Process of obtaining openid on WeChat webpage

I would like to ask you how you can use silent authorization to obtain openid. I am using the QR code to access page 1 and then on page 1 to check whether there is an openid in the session, if no authorization page is displayed, the system returns code to page 2 and openid to page 2... I would like to ask you how you can use silent authorization to obtain openid. I am using the QR code to access page 1 and then on page 1 to check whether there is an openid in the session, if no code is displayed on the silent authorization page, return to page 2, get the openid on page 2, save the code to the session, and return to page 1 at the beginning, another problem is that I use the test number and the domain name bound to the test number. when I access this page, I will ask the user, not the authorization, it is to ask whether to continue the access. I used the public account and there will be no such problem. Therefore, it seems that the style of the domain name that is not bound is sometimes converted. Links and buttons do not work.
