Find the label of the video link. This div is not in the source code

adopt Fiddler grabs the bag , find which js file generated the div of class="mp-h5-player-layer-video"

Open the corresponding js file, breakpoint it, and find the way to generate src

Find the src parameter in this position

At this point, you need to find the source of the string, and then simulate this method

Finally, we found that the string existed in the web page from the very beginning

When a web page is requested, the corresponding string of the video is extracted, and then the URL can be obtained through the simulated method
