Playback Cache Success Callback
Purpose:
For cloud classroom-type playback videos, once the offline cache content of the playback video is successfully generated, a callback notification will be sent to the configured interface address.
Details:
After setting the interface address, if the offline cache file of the playback video is successfully generated, the live streaming system will submit the relevant parameters to the user-defined callback interface via GET method for notification, e.g., http://abc.com/test.do?vid=8205ac89d37e05513c5cb49dcb5f2705_8&zipSize=24016232&zipUrl=//liveimages.videocc.net/ppt/8205ac89d37e05513c5cb49dcb5f2705.zip&origin=auto&sign=f9b45f4a063b3ae312db66b03f9e0fdb&videoId=e529178318&channelId=286500×tamp=1568819519570
