Uniform authentication between discuz and third-party applications

Recently, some projects have used the unified authentication of discuz and the project. They have made great efforts to study discuz.Source codeAnd passport authentication.

At the beginning, we used version 6.1. it was okay to follow the instruction manual for a long time to register. However, it was impossible to achieve the same login. After reading it for a long timeCode.

A little clear. But the cookies are not found in the session. You 'd better choose to stop using version 6.0. Both registration and unified authentication

It can be implemented in a simple way.

In some cases, update the source code. so I read the discuz code and page for a long time. ten again served discuz's code encapsulation. all operations are encapsulated into functions. ten minutes later. the search is dying. to understand what each function means, it takes a long time to find this function. however, I have to admire that the code running efficiency of this forum is indeed very good. currently, PHP is used for development. so this forum is worth my research and study. however, it may take a long time to understand the meaning of each function in this forum. to understand the code.

The code for unified authentication is attached. If you need it, you can learn it. 6.1 of the unified authentication did not study the value of regret.
