Step S204, locally caching the list content corresponding to the second live broadcast room fed back by the server, and sending the list content corresponding to the second live broadcast room to the client for displaying in the second live broadcast room interface of the client.
In step S201, when the user enters a certain live broadcast room, such as a second live broadcast room, a second request for obtaining the list content corresponding to the second live broadcast room is sent, where it is to be noted that when the user enters the second live broadcast room, it may be that the user logs in an account to enter the second live broadcast room, or that the user enters the second live broadcast room with a visitor identity, that is, when the second live broadcast room is opened, the second request for obtaining the list content corresponding to the second live broadcast room is sent, where the second request carries an identifier of the second live broadcast room, such as ID information of the second live broadcast room.
Receiving the step S201, in step S202, according to the identifier of the second live broadcast room, querying whether list content corresponding to the second live broadcast room is cached locally; specifically, whether the list content corresponding to the second live broadcast room exists locally is queried according to the ID information of the second live broadcast room.
In step S203, if the list content corresponding to the second live broadcast room is cached locally, the operation of sending the list content to the client may be performed; and if the list content corresponding to the second live broadcast room is not locally cached, sending a third request for obtaining the list content corresponding to the second live broadcast room to the server, wherein the second request sent by the client is converted into the third request sent to the server when the local cache is not available.
After the step S203, in step S204, after receiving the third request, the server may feed back the third request, that is, feed back the list content corresponding to the second live broadcast. Specifically, the list content corresponding to the second live broadcast room fed back by the server is cached locally, and then the list content corresponding to the second live broadcast room is sent to the client, so that the second request for the client is completed, the list content is displayed in the second live broadcast room interface of the client, that is, the list content is displayed in the second live broadcast room of the client, and for example, the contribution ranking list of the audience to the main broadcast of the second live broadcast room is displayed in the live broadcast picture of the second live broadcast room.
in the embodiment, the request of the client is received, the request is sent to the server when the list content is not cached locally, the list content fed back by the server is cached locally and sent to the client for displaying, the problem that the server is over-stressed due to the fact that the client directly obtains the list content from the server is avoided, and the technical problem that the background server is over-stressed when the anchor live broadcasting room information is obtained in the video live broadcasting field at the present stage is further solved.
EXAMPLE III
Referring to fig. 3, a flowchart of a method of a list information obtaining method according to a third embodiment of the present invention is shown, where on the basis of the first embodiment or the second embodiment, the method further includes the following steps:
Step S300, establishing an information communication mechanism for subscribing the list content corresponding to the at least one live broadcast room with the server based on the locally cached list content corresponding to the at least one live broadcast room, so that the server sends the list subscription information when the list content corresponding to any one or more live broadcast rooms in the at least one live broadcast room changes.
Specifically, a subscription information communication mechanism is established between the locally stored list content corresponding to at least one live broadcast room and the server, and after the list content of the corresponding live broadcast room in the server changes, the new list content after the change sent by the server is received in time. Here, the change in the list contents of the live broadcast rooms means that the list contents of one or more live broadcast rooms in the live broadcast rooms change, in other words, the change in the list contents of the live broadcast rooms is regarded as a change in the list contents of the live broadcast rooms. The reason for establishing the subscription information communication mechanism with the server is to enable the server to send the list subscription information when the list content corresponding to any one or more of the at least one live broadcast rooms changes.
Example four
referring to fig. 4, a flowchart of a method of the list information obtaining method according to the fourth embodiment of the present invention is shown, where on the basis of the first embodiment or the second embodiment, the method further includes the following steps:
In step S400, when a cache invalidation event occurs, deleting part or all of the list content corresponding to the at least one local cache live broadcast room.
specifically, because the storage space of the local cache is limited, the list content sent by the server is not stored unlimitedly, and the list content in the local cache also needs to be cleared, that is, when a cache failure event occurs, part or all of the list content corresponding to at least one live broadcast room of the local cache is deleted, where the cache failure event may be that a request for obtaining the list content from the client is not received for a long time, that a main broadcast account of the live broadcast room logs off on a live broadcast platform, or that the number of viewers who pay attention to the main broadcast of the live broadcast room is less than a certain number.
the specific situation of the cache invalidation event is not specifically limited, and it is only necessary to emphasize that when the cache invalidation event occurs, part or all of the list content corresponding to the at least one local cache live broadcast room is deleted, where it is to be noted that the deletion may be the whole content of the list or the partial content of the list.
EXAMPLE five
Referring to fig. 5, a flowchart of a method of the list information obtaining method according to the fifth embodiment of the present invention is shown, where in this embodiment, on the basis of the fourth embodiment, the method further includes the following steps:
step S501, recording the caching time of the corresponding list content of the third live broadcast room;
step S502, if the time length from the caching moment to the current moment exceeds a threshold value, the caching failure event of the corresponding list content of the third live broadcast room is triggered to be deleted.
In step S501, when the list content sent by the server is cached, a caching time of the list content corresponding to the live broadcast room is recorded, for example, the cached list content includes a generation time of the list content.
in step S502, performing difference processing on the caching time and the current time to obtain a time difference between the caching time and the current time, and when the time difference exceeds a threshold, for example, 72 hours, triggering to delete the cache invalidation event of the list content corresponding to the third live broadcast room, and triggering the cache invalidation event, that is, to delete part or all of the locally cached list content corresponding to the third live broadcast room.
By triggering the cache invalidation event, part or all of the list content of the local cache is deleted, the redundant cache can be timely cleaned, and the local cache pressure is reduced.
