Discuz! Passport 通行证整合

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

第二步: 删除dz安装目录/forumdata/cache/cache_settings.php
第三步: 重新访问论坛

登陆和注册整合流程
用户从登陆或注册表单提交帐号密码信息 ==>
主站程序检验用户登陆或注册,成功(注册需要生成新用户)则 ==>
设置主站自身的cookie或session    ==>
url传递 返回地址forward和编码后的用户信息和其他信息 到dz/api/passport.php

整合之前请先仔细阅读官方passport技术文档: http://www.discuz.net/usersguide/advanced_passport.htm
<?php
//该文档保存为login.php
//首先将接口技术文档里的加密解密函数拷贝
//为了不让代码太乱，我拷贝到文档的结尾处
//假设自己的用户数据库表里用户名字段为UserName, 密码字段为Pwd, Email字段为 Email
//注册页实现方法差不多，可自行实现，疑问加我QQ:2666556

第二篇:php168 v3.5与discuz v4.10的整合
168整站 与 discuz的passport整合

php168整站v3.5与discuz v4.1.0的整合(带视频)

使用说明
请注意自己所用的程序的版本号
login.php 登陆和退出的整合
register.php 注册的整合

整合前请先核对一下你使用的php168的login.php 和 register.php 是否和 整合文件.rar中[原文件] 文件夹下的文件相同
如果不同..请不要整合

(一)准备工作
1.下载php168 v3.5
2.下载discuz bbs v4.1.0

(二)安装和整合 (请参考视频安装)

1.安装php168 v3.5 (如已安装 到第2步) (如何安装请参考php168的安装说明)
2.进入php168的后台管理界面关闭168的论坛整合功能 (新安装可跳过)
3.在php168的安装目录下建立名称为bbs的文件夹
4.下载安装discuz bbs v4.1.0的upload/下的所有文件拷贝到bbs文件夹下
5.运行discuz bbs的install.php 进行安装
6.到discuz的后台管理设置开启通行证
具体参数如下
启用通行证:       是
应用程序 URL 地址: http://localhost/php168/ 根据具体情况设置
通行证私有密匙:   1234567890 (如果这里改了..两个整合文件中的$passportkey的值也必须改成相同的值)
验证字串有效期(秒): 3600
应用程序注册地址:   register.php
应用程序登录地址:   login.php
应用程序退出地址:   login.php?action=quit
积分同步选项:     不同步积分
7.将整合压缩包中的login.php 和 register.php替换 php168下同名的文件
安装完成

第四篇 :Asp整合实例－PowerEasy2006 SP2普及版 与 discuz v4.10的整合

PowerEasy下载地址:http://www.powereasy.net/Soft/PE_soft/181.html

步骤1：
        下载安装powerEasy,下载安装discuz v4.10

步骤2：
        将user_chklogin.asp 覆盖到 powereasy安装根目录/user/user_chklogin.asp
        将user_logout.asp   覆盖到 powereasy安装根目录/user/user_logout.asp
        将user_regpost.asp  覆盖到 powereasy安装根目录/reg/user_regpost.asp
        拷贝discuz_passport文件夹到Powereasy安装根目录

步骤3:  修改discuz_passport里的config.asp文件部分变量
        Discuz_PassportKey="1234567890"                  '这里换成你discuz论坛通行证设置的passportkey
        Discuz_YourAspWeb_Url="http://localhost:8080/"  '这里换成你的主页绝对地址或相对地址
        Discuz_Bbs_Url="http://localhost/discuz/"       '这里换成你的discuz论坛绝对地址或相对地址

步骤4：
        到discuz论坛后台通行证设置开启通行证
        启用通行证:                 是
        应用程序 URL 地址:         http://localhost:8080/        '这里换成你的主页绝对地址或相对地址
        通行证私有密匙:         1234567890                '这里必须与Discuz_Passportkey的值相同
        验证字串有效期(秒):        3600
        应用程序注册地址:        Reg/User_Reg.asp
        应用程序登录地址:        index.asp
        应用程序退出地址:        User/User_Logout.asp
        具体请参照论坛设置图片
