Detailed Description
In the data updating method after updating the video content according to this embodiment, the server caches the video data to cooperate with the CDN to cache the video data to provide video content storage, and the server has a data service, a Node service, a JAVA service, and a GO service, as shown in fig. 1 and fig. 2, the step of the server responding after receiving a video submission request from a video submitting user includes:
1) issuing a notification to a data service;
2) after receiving the release notification, the data service clears the current data cache and caches the latest video data, and notifies the Node service;
3) the Node service starts a data template rendering service to generate a latest video page template and informs the JAVA service;
4) the JAVA service clears the JAVA cache and caches the latest video page template, the CDN is informed of clearing the corresponding cache, and the latest video page template is returned to the source CDN (the JAVA service is pushed to the CDN).
A CDN (content delivery network) is used to provide a nearest site delivery service when a user accesses a site to achieve access acceleration. The cache of the data service can be used for helping the Node service to save the request performance, and a user request can pass through the Node service to carry out data verification and whether the data is hit in the cache or not. The Node service is used for performing HTML template rendering service, the Node service can be separated from the front end and the back end, the front end can be maintained and developed better, and the efficiency can be improved. JAVA services are mainly used to cache video page templates (HTML pages) and also to serve page launch logic, such as user input: www.mgtv.com/b/1235/2346.html, which does not actually have this address, JAVA will do a matter to check if there is a correct video, not returning a default video. In this embodiment, the CDN is a cached video page template (HTML data), the JAVA service caches a video page template (HTML data), the Node service is a rendering service, and the GO service is stored video data. And the Node service calls the video data of the GO service to render pages, and then returns data to the JAVA service.
In fig. 2, the CDN sends/b/cid/vid.html to the JAVA service to start the JAVA service to make a start-up service, to check whether there is a correct video, and if not, returns a default video. When the NODE service sends the VRS update notice to the JAVA service, the VRS update notice specifically refers to the update notice sent by the VRS in the video editing background. The JAVA service has two arrows towards the CDN, which indicates that there are 2 things for the JAVA service, and if the CDN does not have a cache, the CDN takes data to the JAV service. If the editor actively informs that the video is online, the JAVA service is informed of the update, and then the JAVA service informs the CDN that the online cache is about to be cleared and the video page template (HTML template) is updated. The GO service is a data caching service and the odin is a video interface service. The GO service sends the latest data to the NODE service by the video interface service odin and buffers the redis. HTML refers to development for page development, and hoobot is a short for a publishing platform in this embodiment, and is used for platform management for publishing the online static resource.
Generally speaking, a video submitting user is operation editing, and according to the steps, after the operation editing of the updated video, whether the preview video has problems or not can be edited, and if the preview video has no problems, the online video can be released. After the online video is released, a message is sent to the server, so that the response step of the server after receiving the video submission request of the video submission user is executed. Based on the foregoing steps, the response procedure is: the data service receives a notice (1, clear the current data cache.2, cache updated data) > notifies the Node template rendering service to generate the latest video template > notifies the JAVA service (1, clear the JAVA data cache, 2, clear the CDN cache) > CDN obtains the latest page template and caches the latest data.
In addition to submitting requests for video, the video for the video may also need to be updated in time. Therefore, the embodiment further includes a response step after the server receives the video deletion request of the video submitting user, and the detailed steps include:
A1) issuing a notification to a data service;
A2) after receiving the release notification, the data service clears the data cache corresponding to the video deletion request and notifies the Node service;
A3) the Node service directly informs the JAVA service;
A4) and the JAVA service clears the JAVA cache of the video page template corresponding to the video deletion request and informs the CDN of clearing the cache of the video page template corresponding to the video deletion request.
Compared with the steps 1) to 5), the Node service in the step A3) directly notifies the JAVA service because the Node service does not need to render to generate a new video page template; since the CDN only needs to delete, the latest video page template does not need to be returned to the source CDN after step a 4).
The embodiment also comprises the steps that the CDN responds to the video access request of the client, the CDN judges whether the local cache has the corresponding video data or not, and if the local cache has the corresponding video data, the local cache returns the video data to the client initiating the video access request; otherwise, the server cooperates with the CDN to respond to the video access request of the client, referring to fig. 2, where the step of cooperating with the CDN to respond to the video access request of the client includes:
B1) the JAVA service receives a call request of the CDN; the JAVA service verifies the video access request information contained in the call request, and if the verification fails, the operation is ended and quitting is performed; if the verification is passed, whether the corresponding video data are cached in the JAVA cache is judged, and if the corresponding video data are cached, the corresponding video data are returned to the client initiating the video access request through the CDN; otherwise, the JAVA service performs routing judgment to determine the corresponding Node service and call the Node service, and skips to execute the next step;
B2) the Node service calls a data service;
B3) the data service judges whether corresponding video data exist in a cache or not, if the corresponding video data exist in the cache, the corresponding video data are started through the Node service to start a data template rendering service to generate a video page template, and the video page template is returned to a client initiating a video access request through the JAVA service and the CDN in sequence; otherwise, the data service calls the GO service to acquire video data from the video data system according to the video ID data corresponding to the video access request, the acquired video data is processed by the Node service to start a data template rendering service to generate a video page template, and the video page template is returned to the client initiating the video access request through the JAVA service and the CDN in sequence.
As can be seen from the above description, there are four situations in the client initiating the video access request:
in the first case: user access URL CDN has cache, cache reads cache data and returns the cache data to the user
In the second case: the method comprises the steps that a user accesses URL, the CDN does not cache, calls JAVA service, JAVA plays (when the user inputs an incorrect address to check data and access correct data), and the JAVA service returns data cache to the CDN.
In the third case: and after the data is obtained, page rendering is carried out, the data is returned to the JAVA service and then returned to the CDN.
In a fourth case: the method comprises the steps that a user accesses URL, CDN does not cache, calls JAVA service, JAVA service does routing judgment, JAVA service does not have data cache, JAVA service calls Node service, Node service calls data service, data service does not cache data, data service goes to a video data system to obtain corresponding video id data, GO service obtains the corresponding video id data, the obtained video id data is sent to a Node, then the Node enters template rendering data, page rendering is carried out, JAVA is returned, CDN is returned, and one layer of the Node carries out caching.
In this embodiment, an AB test may also be performed as needed. The AB test is to make two (A/B) or a plurality of (A/B/n) versions for a Web or App interface or process, respectively make visitor groups (target population) with the same (similar) components randomly access the versions in the same time dimension, collect user experience data and service data of each group, finally analyze and evaluate the best version, and formally adopt the version. And planting a bucket of cookie on the page in advance at the AB test time, and then the CDN sends the cookie through the page to judge so as to compile the page of the AB version.
