Hello everyone, when I was doing WeChat development, I encapsulated a curl method according to the teacher's video to operate the WeChat interface, but there was a problem during the actual operation. When calling this Before the method, all data can be output normally, but after calling this method, the data cannot be output, and the report is: "errcode":40001,"errmsg":"invalid credential, access_token is invalid or not latest hint: [7Gvnoa0808vr46 !]" error, could you please help me find out if there is anything wrong with the curl method I wrote? Why does it report an error as soon as it is executed?

First make sure the appid and secret are correct, and then check whether the access_token exceeds the request limit (up to 2000 times a day). It is best to add the access_token request to the cache or SESSION, otherwise the upper limit will be reached after just testing in one day
The token is cached. It may be that two tokens are generated locally and online, causing one to expire
