The Douyin remove watermark applet is too bad, you can only download one a day and you need to pay. Or write a good one in Python

For dads who make short Douyin videos, it is absolutely necessary to download a few videos without watermarks every day for reference.

Wechat has many small watermark removal programs like this, but you can only download one for free per day, otherwise you have to open a membership

Think of a way, why not use Python to climb it yourself?

first step

First look at the results obtained by directly accessing Douyin

Next, open the browser's developer tools and look at the address of the video.

Next is the key point. First of all, you need to enable your browser to modify the UA, which is the "User-Agent" that crawlers often use.

Create a folder on your computer

This is the path to the folder

C:\Users\111\Music\MV

And run the following code on the command line in the root directory.

open -n /Applications/Google\ Chrome.app/ --args --disable-web-security --user-data-dir=/Users/star-river/Documents/MyChrome

In this way, you have successfully changed to UA.

Return to the developer mode of the Douyin page

It is found that the interface beginning with "?item_ids" contains the watermark-free Douyin video we want.

In this way, we also know the parameter values of "item_ids" and "dytk".

However, the two links we get directly through browser access will not directly display the video, and need to be the same as above.

Final Python code implementation:
