The original webpage URL has WeChat parameters added at the WeChat entrance. Then you can judge whether it is in WeChat by just checking whether there are parameters. Of course, if your link is in Moments and the chat is clicked, WeChat will also add relevant parameters by default, like this from=timeline, from=groupmessage from=singlemessage.
Another method is to use the UA of WeChat’s built-in browser to determine whether the webpage is opened in WeChat
