The issue of micro-faith OpenID

本人这几天做一个小项目，想通过用户像公共账号发信息之后获取粉丝的信息，中间设计到openID的获取，网上的资料都显示，在接受到的信息中fromUserName就是openid ，但是我通过存储在数据库的信息发现，这个fromUserName 跟测试接口中的openid不一样，只有用到开发账号后台里面显示的openid才能获取到详细的信息。

So I'd like to ask, is there a problem with the way I get it?

OpenID each user is different from each public number, and the test number is certainly not the same.
You certainly didn't read the document carefully ...

Hello, how do you finally solve this problem?
I have also encountered fromusername writing libraries that are different from the OpenID that has been concerned.
