Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
With the vigorous development of the live broadcasting industry, the variety of gifts available for the live broadcasting room is also increasing, resulting in an increasing size of the gifts profile. The types of gifts can reach more than 3000, but only about 100 gifts are commonly used in a living broadcast room. These gifts are mainly used for the following business modules such as a gift shelf, a wrapping gift panel, a public screen gift message, etc.
Wherein, the gift shelf is used for displaying the gift in the state of being put on shelf, generally refer to the gift that can be purchased; the parcel panel is used for displaying the gift owned by the current user, and generally displaying the quantity of the gift owned by the user; the gift public screen message is used for displaying the gift giving condition of the current living broadcast room, and generally displays the user identification of the gift giving and the icon of the gift giving. The display interfaces corresponding to these service modules are typically displayed directly on the user graphical interface provided by the terminal device after the user enters the living room.
After triggering an event entering a living broadcast room through a terminal device, for example, clicking an entry icon of a living broadcast room, a client running on the terminal device generally renders the service module related to gift display through the following logic: and responding to a trigger event entering the living broadcast room, requesting to acquire a configuration file from a server, and rendering business modules such as gift shelves and the like based on the configuration file sent by the server.
The configuration file sent to the client by the server generally contains configuration information of all gifts, and the configuration file is too large, so that the reading of the gift configuration file is slow, the rendering of the service module is slow, and the user can see the gift shelf only after a long time after entering a room. And as the product iterates, the number of gifts is increased, the configuration file is increased, and the time for reading the gift configuration file is longer. Because part of interface rendering and display (such as the display interface of the service module) depends on gift configuration files, the long time required for reading the configuration files can cause slow interface display and clamping, and the user experience is affected. Based on the above, the data processing method and the electronic device for the live broadcast room provided by the embodiment of the invention can be applied to the display process of gifts in various live broadcast scenes.
For the convenience of understanding the present embodiment, first, a data processing method of a live broadcast room disclosed in the present embodiment is described in detail, where the method is applied to a terminal device; providing a graphical user interface by the terminal device, the method comprising the steps of:
Step S102, a first gift configuration request is sent to a server in response to a trigger event entering a live broadcast room, so that the server sends a first configuration file to terminal equipment; the first configuration file comprises configuration information of a hot spot gift, and the hot spot gift is determined by the server in advance according to set conditions.
The triggering event may include monitoring that an icon of the live broadcast room is clicked, that a link of the live broadcast room is clicked, and so on, entering the live broadcast room. After entering the living broadcast room, the living broadcast picture and the display picture of the appointed business module related to the gift are required to be displayed, so that the gift configuration file is required to be acquired from the server after the trigger event is monitored. The first gift configuration request may include an identifier of a user entering the live broadcasting room, verification information, and the like, and the server may determine validity of the request according to the identifier of the user and the verification information, and if the request is legal, send the first configuration file to the corresponding terminal device.
The first configuration file includes configuration information of hot gifts, but not configuration information of all gifts, and is smaller than the configuration file of all gifts. The configuration information generally includes various attribute information such as identification, name, display icon, configuration status, modification time, etc. of the hot spot gift. The hot spot gift is determined for the server according to the set conditions. The server can search the all gifts which are consistent with the set conditions, and determine hot spot gifts.
In general, a gift configured in an upper frame, a gift presented in a last period, and a gift newly added or modified in a set period may be used as a hot spot gift. The server can screen and obtain the hot spot gift through the configuration information of the gift. For example, the configuration information of the gift includes the modification time thereof, the server determines whether the modification time thereof is in a set time period, and if the modification time of the gift is in the set time period, the gift is determined as a hot-spot gift, thereby adding the configuration information of the gift in the first configuration file. In addition, the hot spot gift can be determined according to the type of the gift required by the service module which needs to be displayed in time in the terminal equipment.
Step S104, based on the first configuration file, rendering the appointed business module of the live broadcasting room on the graphical user interface, and displaying the control corresponding to the appointed business module.
Typically, the designated traffic module includes a plurality. The display information of the hot spot gift required by each specified service module can be obtained from the first configuration file in a parsing mode based on the service requirement of each specified service module. For example, the gift shelf module needs to display the gift in the shelf state, and the first configuration file includes configuration information of the hot-spot gift in the shelf state and configuration information of other hot-spot gifts. At this time, the configuration information related to each hot-spot gift may be checked, if the configuration information of the hot-spot gift indicates that the configuration state of the hot-spot gift is the upper frame, the hot-spot gift may be determined to be the hot-spot gift corresponding to the gift frame module, and then the display information, such as an icon, a dynamic video, and the like, of the hot-spot gift may be further obtained from the configuration information in the hot-spot gift. And finally, rendering the gift shelf module based on the display information of all hot spots gift corresponding to the gift shelf module, so as to display the control corresponding to the gift shelf module.
According to the data processing method of the live broadcasting room, the terminal equipment responds to the trigger event entering the live broadcasting room and sends the first gift configuration request to the server so that the server sends the first configuration file to the terminal equipment; the first configuration file comprises configuration information of a hot spot gift, and the hot spot gift is determined by a server in advance according to set conditions; and further, based on the first configuration file, rendering a designated service module of the live broadcasting room on the graphical user interface, and displaying a control corresponding to the designated service module. In the mode, the server determines the hot spot gift based on the setting condition, the first configuration file only comprises the configuration information of the hot spot gift, the file is small, and the terminal equipment can quickly render the appointed service module of the live broadcasting room based on the configuration file, so that the speed of gift display is improved, and the user experience is improved.
The following embodiment provides an implementation manner of rendering a specified service module of a live broadcast room on a graphical user interface based on a first configuration file, and displaying a control corresponding to the specified service module.
In a specific implementation, the configuration file of the gift may be composed of a data table, and the configuration information of each line in the data table may represent a gift, and the configuration information of a gift is displayed as follows:
the first profile (also referred to as "hot spot gift profile") contains only a part of the rows in the table, and the full-volume gift profile (the gift profile acquired by the terminal device in the related art) contains all the rows in the table.
Since the configuration information of the gift includes various kinds, only a case where the configuration information includes a gift id, a gift name, a gift icon, a configuration state, which may be display information of the gift, is shown by way of example. When a designated service module of a live broadcasting room is rendered on a graphical user interface based on a first configuration file, determining a hot spot gift corresponding to the designated service module based on the first configuration file and the preset requirement of the designated service module; and rendering the appointed service module of the live broadcasting room on the graphical user interface based on the display information of the hot spot gift corresponding to the appointed service module.
The designated service module generally includes a gift box module because the user needs to see the gift box of the living room after entering the living room. The configuration information also includes a configuration state of the hot spot gift, where the configuration state may be an upper frame or a lower frame, the configuration state may be represented by a variable, where a value of 1 indicates that the configuration state of the gift is an upper frame, and a value of 0 indicates that the configuration state of the gift is a lower frame. The preset requirements of the gift shelf module are as follows: displaying the gift with the configuration state of being on shelf. When the hot-spot gift corresponding to the gift shelf module is determined, the hot-spot gift with the configuration state of being the upper shelf can be searched from the first configuration file, and then the searched hot-spot gift is determined to be the hot-spot gift corresponding to the gift shelf module.
The appointed service module comprises a package gift module because the gift owned by the user can be displayed on the interface after the user enters the living broadcast room; the first profile includes a category of hotspot gift. The preset requirements of the parcel gift module are: and displaying the gift owned by the current user. When determining the hot spot gift corresponding to the parcel gift module, firstly acquiring parcel gift information corresponding to the current user; package gift information typically includes information on the kind and quantity of the gift owned by the current user, which is typically held by a server; and then, searching the hot-spot gift with the same type as the gift owned by the current user from the first configuration file, and finally determining the searched hot-spot gift as the hot-spot gift corresponding to the package gift module.
The package gift information may be represented by a package gift table, in which package gifts owned by the user are recorded, as follows:
After entering the living broadcast room, the user can display the gift received by the living broadcast room on the interface, so the appointed service module comprises a gift public screen module; the first profile includes a category of hotspot gift. The preset requirements of the gift public screen module are as follows: and displaying the user information of the gift received by the live broadcast. When the hot spot gift corresponding to the designated service module is determined, public screen gift information of the live broadcasting room can be obtained; the public screen gift information comprises the type of the gift received by the live broadcast and the user information of the gift, and is also usually stored by a server; and then, a hot-spot gift with the same type as the gift received by the live broadcast is searched from the first configuration file, and finally, the searched gift is determined to be the hot-spot gift corresponding to the gift public screen module.
The public screen gift information may be recorded by a gift log table, which records the gift gifted by the user, and examples are as follows:
The embodiment of the invention also provides another data processing method of the live broadcasting room, which is applied to the server; the server is in communication connection with the terminal equipment; providing a graphical user interface through the terminal equipment; as shown in fig. 2, the method comprises the steps of:
Step S202, receiving a first gift configuration request; the first gift configuration request is sent by the terminal device in response to a trigger event entering the living room.
The first gift configuration request is sent by the terminal device after detecting that the user needs to enter the living broadcast room, and the request can include identification, verification information and the like of the user. After receiving the first gift configuration request, the server needs to verify the validity of the first gift configuration request based on the user identification and verification information, and if the verification is passed, the next step is performed.
Step S204, a predetermined first configuration file is sent to the terminal equipment, so that the terminal equipment renders a designated service module of the live broadcasting room on the graphical user interface based on the first configuration file, and controls corresponding to the designated service module are displayed; the first configuration file comprises configuration information of a hot spot gift, and the hot spot gift is determined by the server in advance according to set conditions.
Because the terminal device needs to render the designated service module based on the first configuration file, the first configuration file needs to include the configuration information of the gift corresponding to the designated service module, that is, the configuration information of the hot spot gift. The hot spot gift is determined by the server according to a set condition that needs to be considered to meet the service requirements of the specified service module. For example, the gift box module needs to display the gift-giving situation of the living room where the user enters, and the gift-giving situation is usually stored by a server, and the server may select a hot gift from the gift based on the gift-giving situation. In addition, newly added gifts or gifts whose configuration information is modified are easily used, such as purchased or gifted, and they may be determined as hot spot gifts.
According to the data processing method of the live broadcasting room, after receiving the first gift configuration request sent by the terminal equipment, the server sends the predetermined first configuration file to the terminal equipment, so that the terminal equipment renders a designated service module of the live broadcasting room on a graphical user interface based on the first configuration file, and controls corresponding to the designated service module are displayed; the first configuration file comprises configuration information of a hot spot gift, and the hot spot gift is determined by the server in advance according to set conditions. In the mode, the server determines the hot spot gift based on the setting condition, the first configuration file only comprises the configuration information of the hot spot gift, the file is small, and the terminal equipment can quickly render the appointed service module of the live broadcasting room based on the configuration file, so that the speed of gift display is improved, and the user experience is improved.
The following embodiments provide an implementation of determining hot spot gifts.
In a general situation, a server stores configuration information of various gifts in advance; the configuration information may include a configuration state of the gift, a modification time, and a delivery time; the configuration state comprises upper frame or lower frame; the hotspot gift is determined by: searching gift with configuration information meeting the set condition; wherein the setting condition includes one of: the configuration state is upper frame; the modification time is later than the first set time; the sending time is later than the second set time; and determining the found gift as a hot spot gift.
When the configuration information of the gift is modified, the gift may be generally regarded as a hot spot gift, and thus the server needs to monitor the modification operation of the configuration information; the modifying operation may include one of: newly adding configuration information; updating configuration information; deleting configuration information; the modification operation is synchronized to the first configuration file. The modification operation may be performed after the relevant staff member logs in to the client with the administrator identity.
The server generally stores package gift information corresponding to each user; wherein, the package gift information includes the kind and quantity of the gift owned by the user. When a user purchases a gift or gives a gift, the kind and number of the user's possession of the gift may change. The server needs to monitor whether the types and the quantity of the gifts in the package gifts information are changed, and if the types and/or the quantity of the gifts in the package gifts information are monitored to be changed, the gifts with the changed types and/or the changed quantity are determined to be hot gifts.
The embodiment of the invention also provides another data processing method of the live broadcast room, which is realized through a gift display system. The system is schematically shown in fig. 3, and includes a client (corresponding to the "terminal device"), a gift server, a database (where the gift server and the database constitute the "server") and a gift configuration background implementation. The gift configuration background comprises an operable page (client) and a background server. The relevant staff can change the configuration parameters of the gift through the gift configuration background.
The implementation of the method is specifically described below based on the parts of the system.
Client side: when a user enters a living broadcast room through a client, a request is firstly initiated to a gift server to obtain a hot-spot gift configuration file, a local gift shelf interface is rendered and displayed after the hot-spot gift configuration file is read, and a request is initiated to the gift server to obtain a full-quantity gift configuration file after the display is completed, so that other gift related interfaces which do not need to be displayed immediately are rendered.
The server side: the timed task updates the configuration file. The gift service end can set a timing task of 4 am every day, screen out a gift union set according to the following conditions, and update a hot spot gift configuration file:
All gifts on the gift shelf: gift with sal_state=1 in the gift configuration table.
All stock wrap gifts: wrapping the gift in the gift list.
Modified gift for approximately 7 days: the update _ at in the gift configuration table is less than 7 days away from the current time.
Gift sent out for nearly 7 days: and a gift less than 7 days from the current time is datetime in the gift log.
The reason for determining the hot spot gift in the mode is as follows: the gifts in the upper rack are displayed on the gift rack and are necessarily hot-spot gifts. The inventory package gift will be displayed on the package panel, and must be a hot spot gift. The gift modified in the near 7 days is likely to be a play gift about to come or already come online, belonging to the hotspot configuration. The gift sent out in the near 7 days is displayed in the public screen message of the gift, and belongs to the hot spot gift.
Configuration background: modifying the gift configuration. When the product responsible person modifies the gift configuration in the gift configuration background, the following processing is performed according to the operation type:
And (3) newly adding: adding the configuration of the gift id to a hot spot gift configuration file and a full gift configuration file; modification: updating the configuration of the gift id into a hot spot gift configuration file and a full gift configuration file; deletion: the configuration of the gift id is removed from the hot spot gift configuration file and the full gift configuration file.
Since the newly modified gift is likely to be a play gift that is about to be or has been online, it is a hotspot gift.
In addition, when the stock quantity of the package gift changes, if a gift sending action occurs or a user obtains a package gift rewarding, and a modification operation occurs on the package gift table, the server side checks the gift id related to the modification, and if the gift id is not in the hot spot gift configuration file, the configuration of the gift id is added into the hot spot gift configuration file.
Since the gift sending action generates a gift public screen message, the package rewards are displayed on the package panel, and the gift public screen message and the package panel are rendered after the user enters the room, the gift configurations belong to hot spots.
The method accelerates the rendering and displaying of the client gift shelf, the gift message and the package gift panel. For the client, the configuration file reading strategy is adjusted, and the minimum loading strategy can effectively reduce the delay of interface rendering when in starting. For a server, a method for maintaining a hot spot gift configuration file is provided, so that the hot spot gift configuration is ensured to be loaded preferentially.
