Description

Method, device and system for acquiring file

Technical Field

The present invention relates to the field of internet technologies, and in particular, to a method, an apparatus, and a system for acquiring a file.

Background

With the continuous development of internet technology, the amount of network information is larger and larger, and obtaining information by using a network becomes an important way for most users to obtain information. When the amount of information that a user wants to obtain is large, the information that the user needs is often obtained by obtaining a file containing a large amount of information.

The file acquired by the user from the network often has some unknown factors, for example, it is unknown whether the read file exists, whether the file is in a dynamic growth state, when the file can be grown, and the like. In the prior art, an acquisition mode of an unknown file by a common web server is to inquire whether the file exists at intervals and judge the growth state of the file, if the file which a user needs to acquire is in a dynamic growth state, the user cannot acquire the file, and the server can send the file to the user only after the file grows.

By adopting the acquisition mode in the prior art, on one hand, in the process of inquiring the file by the web server, the interval time of the inquiry can cause the file to generate larger time delay in the acquisition process, so that the file has the problem of low timeliness in the acquisition process. On the other hand, only when the file is complete file content, the server can send the file to the user, and a certain time may be spent in the process that the user waits for the file to grow, which wastes user time and causes a problem of poor user experience.

Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

In order to solve the above technical problem, an embodiment of the present invention provides a method for obtaining a file, which is applicable to a file processing server. Fig. 1 is a flowchart illustrating a method for acquiring a file according to an embodiment of the present invention. Referring to fig. 1, the method includes at least steps S102 to S110.

Step S102, receiving a file acquisition request from a client forwarded by a web cluster.

In this step, the File acquisition request may be in the form of a hypertext Transfer Protocol (HTTP), a hypertext Transfer Protocol secure Socket L layer, a File Transfer Protocol (FTP), and the like.

In this step, the web cluster may include a plurality of web servers, such as an Nginx server, an Internet server, and the like, and the type of the server in the embodiment of the present invention is not particularly limited.

And step S104, when determining that the file content requested by the file acquisition request is not stored locally, waiting for a monitoring notification from the file monitoring server, wherein the monitoring notification carries new file content generated due to system file change.

In this step, the file monitoring server may monitor the change of the system file, and may receive the new file content after the change. When the file monitoring server monitors that the system file changes, the file generation server is triggered to generate new file content, the new file content generated by the file generation server is received, and meanwhile the new file content is carried in the monitoring notification and sent to the file processing server.

And step S106, when the monitoring notice is received, reading the new file content carried in the monitoring notice, and judging whether the new file content contains an end mark for ending the file.

In this step, the end flag that the file has ended is actually an identifier indicating whether or not the file content requested by the file acquisition request has been completely generated. The ending mark may be a number, letter, a string, etc. If the new file content contains the end mark, it indicates that the file content requested by the file obtaining request is completely generated, and if the new file content does not contain the end mark, it indicates that the file content requested by the file obtaining request is not completely generated, only a part of the file content is generated, and at this time, the file content requested by the file obtaining request is in a dynamic growth state.

The ending mark in this step may be added to the new file content by the file generation server after the new file content is generated, or may be added to the new file content by the file monitoring server after the new file content sent by the file generation server is received, which is not limited in this embodiment of the present invention.

And step S108, if the end mark is included, deleting the end mark, and sending the deleted file content to the web cluster so as to enable the deleted file content to be forwarded to the client side by the web cluster.

Step S110, if the end mark is not included, the new file content is forwarded to the web cluster, so that the new file content is forwarded to the client by the web cluster, and the monitoring notification carrying the new file content from the file monitoring server is continuously received until the new file content includes the end mark.

In the embodiment of the invention, when the file processing server receives a file acquisition request from the client, which is forwarded by the web cluster, and determines that the file content requested by the file acquisition request is not stored locally, the file processing server can select to wait for a monitoring notification from the file monitoring server, which carries new file content generated due to the change of the system file. If the file processing server receives the monitoring notification sent by the file monitoring server and knows that the new file content carried in the monitoring notification contains the end mark through judgment, the new file growth is finished, the file processing server can send the file content with the end mark deleted to the web cluster, and then the web cluster forwards the file content to the user. If the new file content does not include the end mark, it indicates that the new file is growing, i.e. the requested file content requested by the user is in a dynamic growth state, and the file processing server needs to continue to wait for the monitoring notification of the file monitoring server until the new file content includes the end mark. Therefore, no matter whether the file content requested by the user is in a dynamic growth state or not, the scheme of the invention can ensure that the user can acquire the requested file content in time. Particularly, if it is known through the judgment that the new file content does not include the end flag, that is, the requested file content requested by the user is in the dynamic growth state, the file processing server will wait for the monitoring notification of the file monitoring server, timely receive the generated new file content until the new file content includes the end flag, and when the new file content includes the end flag, the file content requested by the user at this time is completely acquired. In the process, the user does not need to acquire the requested file content after waiting for all the requested file content to be generated, so that the file acquisition instantaneity can be effectively improved, the time for the user to wait for the requested file content to be generated is reduced, and the operation experience of the user is further improved.

Referring to step S102 above, in an embodiment of the present invention, when the web cluster receives a request from a client, a web server for receiving a file obtaining request may be selected in the web cluster according to a load balancing algorithm. Load balancing refers to dynamically adjusting the load condition of each station (e.g., server) in the system to eliminate or reduce the phenomenon of load imbalance of each station in the system as much as possible. The specific implementation method can be that the tasks on the heavy-load sites are transferred to other light-load sites, and the load balance of all the sites in the system is realized as much as possible, so that the throughput of the system is improved. In this embodiment, the file retrieval request may be distributed to the server with a lower load in the web cluster, so that the server with a lower load may process the file retrieval request task.

Referring to step S104 above, in an embodiment of the present invention, if the file processing server determines that the file content requested by the file obtaining request is locally stored, the file processing server may directly read the requested file content and send the file content to the web cluster, so that the requested file content is forwarded to the client by the web cluster. When the file content requested by the file acquisition request is sent to the web cluster, the requested file content can be packaged into a chunk form, and then the requested file content is sent to the web cluster in the chunk package form.

With continued reference to step S104 above, in an embodiment of the present invention, when the file monitoring server monitors that the system file changes, for example, the system file is created, deleted, or modified, the file generation server may generate new file content according to the created, modified, or deleted system file, so that the file monitoring server carries the generated new file content in the monitoring notification and sends the monitoring notification to the file processing server.

In this embodiment, when the file processing server waits for a monitoring notification from the file monitoring server, which carries new file content generated due to a change in the system file, it may further determine whether the file processing server needs to continue to wait for the monitoring notification by determining whether a waiting time for the monitoring notification from the file monitoring server exceeds a preset time. For example, the preset time may be 3 seconds, 4 seconds, 5 seconds, and the like, and the preset time is not specifically limited in the embodiment of the present invention.

If the waiting time of the file processing server for waiting the monitoring notification does not exceed the preset time, reading the new file content carried in the monitoring notification when the monitoring notification is received, and further judging whether the new file content contains an end mark indicating that the file is ended or not.

If the waiting time of the file processing server for waiting the monitoring notification exceeds the preset time, determining that the file acquisition request fails, sending a notification message of the file acquisition request failure to the web cluster by the file processing server, and forwarding the notification message of the request failure to the client by the web cluster. The notification message of the request failure may be in the form of voice, text, number, etc. For example, a text notification message "file acquisition failed, please acquire file again".

Referring to step S106, in an embodiment of the present invention, when the file processing server reads new file content carried in the monitoring notification, the file monitoring server monitors that the file acquisition request sent by the client to the web cluster is disconnected, for example, when any one of the client and the web cluster fails, the network is disconnected, or a user closes the client, refreshes a page displayed by the client, and the like, the connection of the file acquisition request between the client and the web cluster is disconnected. At this time, the file monitoring server triggers the file processing server to interrupt reading of new file contents, and the file processing server sends an interrupt notification message to the web cluster, and then the web cluster forwards the interrupt notification message to the client, so that the user knows that file acquisition fails.

In order to more clearly embody the embodiments of the present invention, the present invention will be described with reference to embodiments in a specific context. In this embodiment, the client is a "360-degree secure browser," and the file content requested by the file acquisition request is video content.

When a user opens the 360-degree safety browser and clicks the video on the 360-degree safety browser page, the 360-degree safety browser sends an http protocol request to the corresponding web cluster. When the web cluster receives the http protocol request, a web server with a lower current load can be selected to receive the http protocol request, and after the selected web server receives the http protocol request, the http protocol request is forwarded to the file processing server.

When a file processing server receives an http protocol request of a video file 'cheering', whether the content of the video file 'cheering' is stored in the local is determined, if yes, the video file 'cheering' is directly sent to a web server, and after transcoding and caching are carried out on the video file 'cheering' according to the sequence of a video timeline, the web server sends the transcoded video file to a '360-degree safety browser', so that the video 'cheering' is played on the '360-degree safety browser'.

If the file processing server is determined not to store the video file content of the 'cheering-opening', the file processing server can select to wait for the monitoring notification from the file monitoring server. When the file monitoring server monitors that a video file 'cheering-opening' in the system is created, the file generating server is triggered to generate the video file 'cheering-opening'. After the file generation server generates partial contents of the video file, the generated partial contents of the video file are sent to the file monitoring server, and then the file monitoring server carries the partial contents of the video file in a monitoring notice and sends the monitoring notice to the file processing server. After receiving the monitoring notification, the file processing server reads out part of the video file content from the monitoring notification, namely 'cheering open'.

If the file processing server knows that the content of the part of the video file 'cheering' does not contain the end mark through judgment, the content of the part of the video file 'cheering' is directly forwarded to the web server and continues to wait for the monitoring notification. Then, the web server transcodes and caches the received partial video file content according to the sequence of the video timeline, and then sends the content to the 360-degree safety browser. And then the 360-degree safe browser plays the received partial video file content 'cheering' according to the transcoding sequence.

And if the file processing server knows that the part of the video file content contains the end mark through judgment, deleting the end mark and sending the part of the video file content to the web server. The web server transcodes and caches the received part of the video file content according to the sequence of the video timeline, and then sends the part of the video file content to the 360-degree safety browser. And then the 360-degree safe browser plays the received partial video file content 'cheering' according to the transcoding sequence.

Of course, the above embodiments are merely illustrative, the file content requested by the file obtaining request is not limited to the video file, but may be any other file content, such as text file content, audio file content, and the like. However, the process of file acquisition is substantially the same, and this is not described in any more embodiments of the present invention.

The embodiment of the invention also provides another method for acquiring the file, which is suitable for the file monitoring server. Fig. 2 is a flowchart illustrating a method of acquiring a file according to another embodiment of the present invention. Referring to fig. 2, the method includes at least steps S202 to S206.

Step S202, system file change is monitored.

In this step, the monitoring system file change may specifically be various change states of the system file such as the system file being created, modified, or deleted.

And step S204, when the system file is monitored to be changed, receiving the changed new file content.

In this step, the changed new file content may be generated by the file generation server according to the created, modified or deleted system file.

Step S206, the received new file content is carried in the monitoring notice and sent to the file processing server, so that the file processing server sends the new file content to the web cluster, and then the web cluster sends the new file content to the client.

Referring to step S204 above, in an embodiment of the present invention, when the file monitoring server monitors that the system file is created, modified, or deleted, the file generation server may generate new file content according to the created, modified, or deleted system file and send the new file content to the file monitoring server, and then the file monitoring server forwards the received new file content to the file processing server.

In an embodiment of the present invention, the file monitoring server may be further configured to monitor a network connection status between the client and the web cluster. When it is monitored that a file acquisition request sent by a client to a web cluster is disconnected, for example, a failure occurs in any one of the client and the web cluster, a network is disconnected, or a user closes the client, refreshes a page displayed by the client, and the like, the connection of the file acquisition request between the client and the web cluster is disconnected. And triggering the file processing server to interrupt the reading of the new file content, and triggering the file processing server to send an interrupt notification message to the web cluster, so that the interrupt notification message is forwarded to the client by the web cluster, and the user knows that the file acquisition fails.

The embodiment of the invention utilizes the file monitoring server to monitor the change of the system file in real time, so that when the file monitoring server monitors the change of the system file, a user can acquire the generated new file content in time, thereby effectively improving the real-time property of acquiring the file.

Based on the same inventive concept, the embodiment of the invention also provides a device for acquiring the file, which is suitable for the file processing server.

The embodiment of the invention can enable the user to acquire the requested file content without waiting for the requested file content to be generated completely, thereby not only effectively improving the real-time property of acquiring the file, but also reducing the time for the user to wait for the requested file content to be generated and improving the operation experience of the user.

According to any one or a combination of the above preferred embodiments, the following advantages can be achieved by the embodiments of the present invention:

in the embodiment of the invention, when the file processing server receives a file acquisition request from the client, which is forwarded by the web cluster, and determines that the file content requested by the file acquisition request is not stored locally, the file processing server can select to wait for a monitoring notification from the file monitoring server, which carries new file content generated due to the change of the system file. If the file processing server receives the monitoring notification sent by the file monitoring server and knows that the new file content carried in the monitoring notification contains the end mark through judgment, the new file growth is finished, the file processing server can send the file content with the end mark deleted to the web cluster, and then the web cluster forwards the file content to the user. If the new file content does not include the end mark, it indicates that the new file is growing, i.e. the requested file content requested by the user is in a dynamic growth state, and the file processing server needs to continue to wait for the monitoring notification of the file monitoring server until the new file content includes the end mark. Therefore, no matter whether the file content requested by the user is in a dynamic growth state or not, the scheme of the invention can ensure that the user can acquire the requested file content in time. Particularly, if it is known through the judgment that the new file content does not include the end flag, that is, the requested file content requested by the user is in the dynamic growth state, the file processing server will wait for the monitoring notification of the file monitoring server, timely receive the generated new file content until the new file content includes the end flag, and when the new file content includes the end flag, the file content requested by the user at this time is completely acquired. In the process, the user does not need to acquire the requested file content after waiting for all the requested file content to be generated, so that the file acquisition instantaneity can be effectively improved, the time for the user to wait for the requested file content to be generated is reduced, and the operation experience of the user is further improved.
