Realize the effect:
- Copy and share link on Douyin
- Paste the share link to the App, click Parse
- Click to download to enter the browser to download
Get the video link without watermark
First, we use the browser to open the shared link
Then open the console to find the corresponding video, right-click to check the link to find the video,
https://www.douyin.com/aweme/v1/play/?video_id=v0200fg10000ca08sgbc77udtm7m06p0
then open this link in the browser and find that it is a video without a watermark, and the video downloaded later uses this link.
By testing other shared videos, it is found that it is different The video_id corresponding to the video is different, so we need to find the request to get the video_id.
https://www.douyin.com/aweme/v1/play/?video_id=xxx
Change the device to a mobile device through the console, click the link to share https://v.douyin.com/Y5SpHKD/, and then a request comes into our sight:
https://www.iesdouyin.com/web/api/v2/aweme/iteminfo/?item_ids=7097830584419962125
the response of the request has the video_id we need
. The request has a parameter item_ids, which is part of the redirect link after clicking the share link
, so we only need to parse the link to get item_ids
So far, you have obtained the whole process of downloading the video without watermark.
- Obtain item_ids=7097830584419962125 according to
https://v.douyin.com/Y5SpHKD/the redirection addresshttps://www.iesdouyin.com/share/video/7097830584419962125 https://www.iesdouyin.com/web/api/v2/aweme/iteminfo/?item_ids=7097830584419962125Get the vid according to the response- According to
