javascript - How to obtain openID on H5 page outside WeChat official account?

Question

To develop a service account public account, configure the menu, click the menu to enter the H5 page, and you can silently authorize and get the openID. The problem is, there is another requirement: scan the code to enter a certain menu H5 page (not through the public account, so If you have not entered the official account), you cannot get openID at this time. What is the reason? Is it because you cannot get openID outside the WeChat official account?

Answer 1

Your menu obtains openID through "WeChat webpage authorization", right? Just make the same URL as the menu into a QR code. For example, the URL in the following format:

https://open.weixin.qq.com/connect/oauth2/authorize?appid=wx520c15f417810387&redirect_uri=https%3A%2F%2Fchong.qq.com%2Fphp%2Findex.php%3Fd%3D%26c%3DwxAdap

Answer 2

If you scan the QR code or click on the shared link, there will be no silent authorization. To change it to userinfo authorization, the user needs to manually click to agree
