Applet cannot get user information.

The solution to the failure of applet to obtain user information is as follows

Many times we need users to obtain user information when dealing with applet functions, but for information security reasons, users are not authorized and authorization fails; However, the second time, the applet did not start the authorization information layer. In order to give users the experience of 1, the project was launched several times in half a year. After going online this time, three customers reported that they could not log in, and other users were normal. 2. Customer feedback: Click the login button and there is no response. Usually, you should prompt the authorization box. 3. It is normal for customers to use other WeChat applets. 4. Let the user scan the code and log in to my local developer tool, and all operations are normal.
