太简单了，但时间长了，记不得，浪费我半小时找资料，深刻体会好记性不如烂笔头！！今天把passport文挡贴上，防止以后忘记！！记住，网上找到自己需要的资料也要耗时间的!!!!!!

Passport 通行证 整合

第一篇：整合原理

请注意: 整合不成功可能造成的后果-----dz论坛无法登录,无法管理
解决办法:
第一步: 到dz的数据库表cdb_settings 找到下面这几行修改为

Step 2: Delete the dz installation directory/forumdata/cache/cache_settings.php
Step 3: Re-visit the forum


Log in and register Integration process
The user submits the account and password information from the login or registration form ==> Set the cookie or session of the main website itself ==>
url passes the return address forward and encoded user information and other information to dz/api/passport.php


integration Please read the official passport technical documentation carefully beforehand:
http://www.discuz.net/usersguide/advanced_passport.htm Copy content to clipboard

Code:

//Save this document as login.php//First copy the encryption and decryption function in the interface technical document
/ /In order not to make the code too messy, I copied it to the end of the document
//Assume that the user name field in my user database table is UserName, the password field is Pwd, and the Email field is Email
//Registration page implementation The method is similar and you can implement it yourself. If you have any questions, please send me QQ:2666556
