PHP version of the micro-letter automatically login and get nicknames _php instance

This article describes the PHP version of the micro-letter automatic login and get a nickname method. Share to everyone for your reference, specific as follows:

Micro-letter Automatic login and get nickname is through the API interface can be obtained through the micro-letter open Interface to achieve, let's take a look at an example

Record only: Micro-credit get nickname Auto Login

After several repeated verification, I found this method is flawed:

The micro-letter did not pay attention to access to the site, can not get nickname.

After paying attention, I can get a nickname with this method.

Is the nickname not generated because of the first generation of OpenID? Pending Test.
