Where is the code that shares a page in a friend's circle on a phone?

Where is the code that shares a page in a friend's circle on a phone? I looked for Baidu to share, but Baidu generated a two-dimensional code to let users sweep, why some software can use a button to share the circle of friends?

Look at that JS-SDK .

It's on SF.

The mobile browser is not shared, and then the app has the ability to share it with a circle of friends. JSSDK is an on-site browser that can be shared. It's not possible to share a friend's circle with a website that you want to visit via a mobile browser.

Just looking for this problem, found that only the app can achieve this function
