15.6 和15.7版本的gitlab在集成阿里云oauth登录时，登录通过之后跳回到gitlab界面报错提示：

Could not authenticate you from Alicloud because "Redirect uri mismatch: redirect uri mismatch. {"request id":"aec60fc5-7953-43c0-882b-b8f2eb8df85c","error description":"redirect uri mismatch.","http code":400,"error":"redirect uri mismatch"}".

Steps to reproduce

Example Project

What is the current bug behavior?

通过阿里云的密码验证之后，应该会跳转登录进入gitlab界面，实际上没有。检查阿里云的oauth配置都是正确的。

What is the expected correct behavior?

通过阿里云的密码验证之后，会跳转登录进入gitlab界面。该功能在15.0左右版本是正常的，最近的几个版本都存在这个问题。
