Detailed Description

In order to make the objects, technical solutions and advantages of the present disclosure more apparent, the technical solutions of the present disclosure will be clearly and completely described below with reference to the specific embodiments of the present disclosure and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person skilled in the art without making any inventive step based on the embodiments in the description belong to the protection scope of the present application.

The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

At present, in order to increase the page loading speed and further improve the user experience, a page is generally split into a page frame and a plurality of components during page development. In the page loading process, the client can load the page frame of the page and render and display the page frame of the page, so that the waiting time of a user is reduced. And then sending a component acquisition request to a corresponding server according to the component identification of the component contained in the page frame so as to asynchronously acquire the component resource and carry out component loading.

But when the network state of the client is poor and the data volume of the component is large, the component loading speed is still slow. Therefore, the present specification provides a page component loading method, which is implemented by presetting component resources corresponding to a plurality of versions in different network states, so that in a component loading process, the component resources corresponding to the versions can be loaded according to the network state of a client, thereby increasing the loading speed of the component and improving the user experience.

Fig. 1 is a schematic view of a page component loading flow provided in an embodiment of the present specification, which specifically includes the following steps:

s100: and receiving a page acquisition request sent by a client.

S102: and determining the frame resource of the page according to the page identifier contained in the page acquisition request, and returning the determined frame resource of the page to the client.

The page component loading method provided by the present specification may be specifically executed by a server providing a page resource, where the server may be a single server, or a system composed of multiple servers, such as a distributed server, and the like.

Since the present specification is a method for loading components in a page loading process, in the present specification, the server may execute the page component loading method when receiving a page acquisition request sent by a client.

Specifically, the server may receive a page obtaining request sent by a user through a client, where the page obtaining request includes a page identifier of a page to be loaded.

Then, the server may determine, according to the page identifier included in the received page acquisition request, a frame resource of the page corresponding to the page identifier from stored frame resources of each page, where the frame resource of the page includes the page frame of the page and the component identifiers of each component in the page.

And finally, returning the determined frame resource of the page to the client, so that the client renders and displays the page frame of the page according to the frame resource of the page.

S104: and receiving a component acquisition request sent by the client.

In one or more embodiments of the present description, in order to increase the page loading speed, the server may determine which version of component resource needs to be issued in real time according to the network state of the client after issuing the frame resource of the page, so as to reduce the page loading duration and improve the user experience.

Therefore, the server can receive the component acquisition request sent by the client after issuing the frame resource of the page, and then issue the corresponding component resource. The component acquisition request comprises a component identifier of the component and a network state of the client. To determine, through subsequent steps, the component resources corresponding to the component identification and the network status.

S106: and determining a plurality of versions of component resources corresponding to the component according to the component identification of the component contained in the component acquisition request.

S108: and determining the component resources corresponding to the network state from the determined component resources of the plurality of versions corresponding to the component according to the network state of the client contained in the component acquisition request.

The page component loading method provided by the specification is characterized in that a plurality of versions of component resources corresponding to different network states are preset, so that the component resources corresponding to the versions can be issued to a client according to different network states of the client in the component loading process, and the loading speed of a page component is increased when the network state of the client is poor.

Therefore, in this specification, the server may store, for each component, several different versions of component resources corresponding to the component in advance. Wherein, the component resources of different versions can realize the same component function, corresponding to different network states respectively. The worse the network state, the worse the configuration of the corresponding component resources, the smaller the data volume. The component loading can be performed subsequently by the page component loading method provided by the present specification.

Specifically, the server may determine, according to the component identifier of the component included in the received component acquisition request, the component resources of the versions corresponding to the component from among the component resources of the versions corresponding to each component stored in advance.

Then, the server may determine, from the plurality of versions of component resources corresponding to the component, the component resource corresponding to the network state of the client according to the network state of the client included in the component acquisition request and a preset correspondence between each different network state and each different version of component resource.

For example, when a news page is loaded, if the network status of the client is the fourth generation communication technology (4G) or Wireless Fidelity (WIFI), the server may issue a video playing component to play video in the news page. If the network state of the client is 3G or 2G, the server can issue component resources for displaying pictures and characters so as to display the pictures and the character information in a news page.

Further, the network status included in the component acquisition request may be a network type in which the client is currently located, such as 2G, 3G, 4G, WIFI, and the like. Of course, the network information may be the current network speed of the client and the like for characterizing the current network condition of the client.

When the network state included in the component acquisition request is the current network speed of the client, the server may determine, according to the network speed of the client, an interval range within which the network speed of the client falls from preset interval ranges of the network speeds. And then, according to the corresponding relation between the preset interval range and the component resources of each version of the component, determining the component resource corresponding to the interval range from the component resources of a plurality of versions corresponding to the component, and using the component resource as the component resource corresponding to the network speed of the client.

S110: and returning the determined component resources to the client so that the client carries out component loading according to the received component resources.

In one or more embodiments of the present specification, after the server determines the component resource corresponding to the current network state of the client, the server may issue the determined component resource to the client, so that the client loads the component to complete page loading.

Specifically, the server may return the determined component resource to the client, so that the client loads the component according to the received component resource, and renders and displays the component in the page frame of the page. The component resource is adaptive to the current network state of the client, so that the loading speed of the component is more consistent with the current network state of the client and more consistent with the user requirement.

Based on the page component loading method shown in fig. 1, a page acquisition request sent by a client may be received first, and according to a page identifier included in the page acquisition request, a frame resource of the page may be returned to the client. And then receiving an assembly acquisition request sent by the client, determining a plurality of versions of assembly resources corresponding to the assembly according to the assembly identification of the assembly contained in the assembly acquisition request, and determining the assembly resources corresponding to the network state from the plurality of versions of assembly resources corresponding to the assembly according to the network state of the client contained in the assembly acquisition request. And finally, returning the determined component resources to the client so that the client carries out component loading according to the received component resources. And determining and issuing component resources of corresponding versions based on the network state of the client, so that the speed of loading the components in the client is improved, and the requirement of loading the components in the client is better met.

In another embodiment of this specification, when the server receives a page update request sent by the client, it may determine whether the network state of the client changes according to the network state in the page update request and the network state in the page acquisition request received last time. If the network state of the client changes, according to the network state in the page update request, determining the component resource corresponding to the network state in the update request from the component resources of the versions corresponding to the component determined in step S106 again, and returning the component resource to the client. So that the client renews the component according to the received component resource. If the network state of the client is not changed, returning specified information to the client, wherein the specified information is used for representing that the component resource is not changed. So that the client can perform component loading according to the component resource that received the component most recently.

Alternatively, in other embodiments of the present specification, after receiving again a page obtaining request sent by the client for obtaining the page, the server may also determine whether the network state of the client changes according to the network state included in the page obtaining request and the network state in the page obtaining request that is received last time for obtaining the page. If the network state of the client changes, according to the network state in the re-received page acquisition request, determining the component resource corresponding to the network state from the component resources of the versions corresponding to the component determined in step S106 again, and returning the component resource to the client. So that the client renews the component according to the received component resource. If the network state of the client is not changed, returning specified information to the client so that the client can load the component according to the component resource which receives the component last time.

Based on the page component loading method shown in fig. 1, the present specification also correspondingly provides a page component loading method executed on the client side. Another page component loading flow diagram provided in this specification, as shown in fig. 2, may specifically include the following steps:

s200: and sending a page acquisition request to the server.

S202: and receiving the frame resource of the page returned by the server.

In the page loading process in this specification, by separately loading the page frame in the page and each component in the page, on one hand, the waiting time of a user can be reduced, and the user experience can be improved, and on the other hand, the server can issue component resources having the same function but a smaller data volume according to the network state of the client, so as to improve the loading speed of the component.

Therefore, in this specification, when loading a page, the client may first send a page obtaining request to the server, where the page obtaining request includes a page identifier of the page to be loaded. And then, the client can receive the frame resource of the page returned by the server and render and display the page frame of the page according to the received frame resource of the page.

Further, in this specification, the frame resource of the page further includes a component identifier of a component in the page, and when the page includes a plurality of components, since not all the components may correspond to component resources of different versions in different network states, the data amount of some components is small, and it is not necessary to display component information of different versions in different network states. Therefore, for a component less affected by the network state, the component can be taken as a synchronization component and carried in the framework resource to be synchronously loaded to the client.

The client can render the page frame and the synchronization component for displaying the page according to the frame resource and the component resource of the synchronization component contained therein when receiving the frame resource returned by the server, so as to reduce the waiting time of the user.

S204: and sending a component acquisition request to the server according to the component identification of the component in the framework resource and the network state of the client.

According to the page component loading method provided by the specification, when the component resources are acquired, the client side can send the local network state to the server, so that the server issues the component resources of the corresponding version, and the loading speed of the component is improved.

Specifically, the client may determine the component identifier of the component to be loaded in the page according to the frame resource of the received page. In addition, since the network status of the local environment of the terminal may change, the client needs to detect the local network status information in real time. And then, determining a component acquisition request according to the component identifier of the component to be loaded in the page and the network state detected in real time, and sending the component acquisition request to the server to acquire the component resource of the component.

S206: and receiving the component resources of the components returned by the server.

S208: and loading the components according to the received component resources of the components.

In this specification, after sending a component acquisition request to a server, a component resource returned by the server may be received, so as to perform rendering display according to the received component resource.

Specifically, the client may receive the component resources of the component returned by the server. The component resources of the component are determined from the component resources of the plurality of versions corresponding to the component by the server according to the network state included in the component acquisition request, and the component resources of the plurality of versions corresponding to the component can realize the same function, but the data volume of the component resources of each version is different and respectively corresponds to different network states. When the network state of the client is better, the component resources with larger data volume can be loaded, and the components with better performance are displayed. When the network state of the client is poor, the component resource with small data volume can be loaded so as to ensure that the user normally uses the component to execute the service.

Then, the client can load the component according to the received component resource and render and display the component in the page frame of the page.

Based on the page component loading method shown in fig. 2, in the page loading process, a page acquisition request may be sent to the server first, so as to receive the frame resource of the page returned by the server. Then, according to the component identifier of the component in the framework resource and the network state where the client is located, a component acquisition request is sent to the server to receive the component resource of the component returned by the server, and finally, component loading is performed according to the received component resource of the component. The frame resources and the component resources of the page are loaded separately, and the component resources corresponding to the network state are obtained based on the network state of the client to load the components, so that the time for loading the components in the client is reduced.

In another embodiment of this specification, the page to be loaded may also include a plurality of components, and then the frame resource received in step S202 includes component identifiers of the components. Then, the client may send a component obtaining request for obtaining the component to the server for each component in the page, where the component obtaining request includes a component identifier of the component and a network state of the client. And then receiving the component resource of the component returned by the server, and loading the component according to the received component resource of the component.

In this specification, a server that provides a frame resource of a page and a server that provides a component resource may be the same server or different servers, and when the page includes a plurality of components, each component may be acquired from a different server. The specification does not limit this, and the setting can be specifically set as required.

In addition, in this specification, when a same component is set corresponding to a plurality of versions of component resources in different network states, the worse the network state is, the smaller the data amount of the component resource corresponding to the version is, so that the client can increase the loading speed of the component in the case of a bad network state. For example: and when the chat component in the chat interface is loaded, if the network state of the client is in 3G, loading the chat component of the text version. And if the network state of the client is in 4G, loading the voice chat component. And if the network state of the client is in the WIFI, loading the video chat component.

Or when the map display component in the map interface is loaded, if the network state of the client is in 3G, displaying the two-dimensional map and displaying the two-dimensional route. And if the network state of the client is 4G or WIFI, displaying a three-dimensional map and displaying a scene in Virtual Reality (VR). Of course, based on the difference of the application scenarios, component resources of a plurality of versions corresponding to different application scenarios may be set, which is described above by taking a chat scenario and a map display scenario as examples, and may be specifically set according to business needs, and this description does not limit this.

Of course, besides the software implementation, the present specification does not exclude other implementations, such as logic devices or a combination of software and hardware, and the like, that is, the execution subject of the following processing flow is not limited to each logic unit, and may be hardware or logic devices.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.

The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.

The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.

For convenience of description, the above devices are described as being divided into various units by function, and are described separately. Of course, the functions of the various elements may be implemented in the same one or more software and/or hardware implementations of the present description.

As will be appreciated by one skilled in the art, embodiments of the present invention may be provided as a method, system, or computer program product. Accordingly, the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects. Furthermore, the present invention may take the form of a computer program product embodied on one or more computer-usable storage media (including, but not limited to, disk storage, CD-ROM, optical storage, and the like) having computer-usable program code embodied therein.

The present invention is described with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the invention. It will be understood that each flow and/or block of the flow diagrams and/or block diagrams, and combinations of flows and/or blocks in the flow diagrams and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, embedded processor, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.

These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instruction means which implement the function specified in the flowchart flow or flows and/or block diagram block or blocks.

These computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.

In a typical configuration, a computing device includes one or more processors (CPUs), input/output interfaces, network interfaces, and memory.

The memory may include forms of volatile memory in a computer readable medium, Random Access Memory (RAM) and/or non-volatile memory, such as Read Only Memory (ROM) or flash memory (flash RAM). Memory is an example of a computer-readable medium.

Computer-readable media, including both non-transitory and non-transitory, removable and non-removable media, may implement information storage by any method or technology. The information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), Static Random Access Memory (SRAM), Dynamic Random Access Memory (DRAM), other types of Random Access Memory (RAM), Read Only Memory (ROM), Electrically Erasable Programmable Read Only Memory (EEPROM), flash memory or other memory technology, compact disc read only memory (CD-ROM), Digital Versatile Discs (DVD) or other optical storage, magnetic cassettes, magnetic tape magnetic disk storage or other magnetic storage devices, or any other non-transmission medium that can be used to store information that can be accessed by a computing device. As defined herein, a computer readable medium does not include a transitory computer readable medium such as a modulated data signal and a carrier wave.

It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.
