Token authentication failure and family members

Solution to token verification failure:

When using URL and token to enable the message interface of WeChat public platform development mode, we will encounter the following three situations. Token validation failed, so please check that each configuration is correct. Token is a string in the form of numbers or letters, which is used for authentication when WeChat server communicates with your server. Prevent illegal data from confusing.

URL is the web address where the interface program is placed. This URL must usually be your own server or space address. You already have an interface program in a directory in this space, and you know the access address of this interface program on the Internet.
