I have A subscribe number. Fan A shares A link. When B clicks this sharing link, can I get B's openid?

It should be okay. If you are talking about fans, you should pay attention to the public account. If you use WeixinApi of js to finish sharing, you will know whether the user has successfully shared the message. When the sharing is successful, you can use the "OAuth2.0 webpage authorization" function in the Advanced Interface to obtain user information.
