解決辦法:
第一步: 到dz的數據庫表cdb_settings 找到下面這幾行修改為
第二步: 刪除dz安裝目錄/forumdata/cache/cache_settings.php
第三步: 重新訪問論壇
登陸和注冊整合流程
用戶從登陸或注冊表單提交帳號密碼信息 ==>
主站程序檢驗用戶登陸或注冊,成功(注冊需要生成新用戶)則 ==>
設置主站自身的cookie或session ==>
url傳遞 返回地址forward和編碼後的用戶信息和其他信息 到dz/api/passport.php
整合之前請先仔細閱讀官方passport技術文檔: http://www.discuz.net/usersguide/advanced_passport.htm

//首先將接口技術文檔裡的加密解密函數拷貝
//為了不讓代碼太亂，我拷貝到文檔的結尾處

//注冊頁實現方法差不多，可自行實現，疑問加我QQ:2666556

第二篇:php168 v3.5與discuz v4.10的整合
168整站 與 discuz的passport整合
php168整站v3.5與discuz v4.1.0的整合(帶視頻)
使用說明
請注意自己所用的程序的版本號
login.php 登陸和退出的整合
register.php 注冊的整合
整合前請先核對一下你使用的php168的login.php 和 register.php 是否和 整合文件.rar中[原文件] 文件夾下的文件相同
如果不同..請不要整合
(一)准備工作
1.下載php168 v3.5
2.下載discuz bbs v4.1.0
(二)安裝和整合 (請參考視頻安裝)
1.安裝php168 v3.5 (如已安裝 到第2步) (如何安裝請參考php168的安裝說明)
2.進入php168的後台管理界面關閉168的論壇整合功能 (新安裝可跳過)
3.在php168的安裝目錄下建立名稱為bbs的文件夾
4.下載安裝discuz bbs v4.1.0的upload/下的所有文件拷貝到bbs文件夾下
5.運行discuz bbs的install.php 進行安裝
6.到discuz的後台管理設置開啟通行證
具體參數如下
啟用通行證: 是
應用程序 URL 地址: http://localhost/php168/ 根據具體情況設置
通行證私有密匙: 1234567890 (如果這裡改了..兩個整合文件中的$passportkey的值也必須改成相同的值)
驗證字串有效期(秒): 3600
應用程序注冊地址: register.php
應用程序登錄地址: login.php
應用程序退出地址: login.php?action=quit
積分同步選項: 不同步積分
7.將整合壓縮包中的login.php 和 register.php替換 php168下同名的文件
安裝完成

第四篇 :Asp整合實例－PowerEasy2006 SP2普及版 與 discuz v4.10的整合
PowerEasy下載地址:http://www.powereasy.net/Soft/PE_soft/181.html
步驟1：
下載安裝powerEasy,下載安裝discuz v4.10
步驟2：
將user_chklogin.asp 覆蓋到 powereasy安裝根目錄/user/user_chklogin.asp
將user_logout.asp 覆蓋到 powereasy安裝根目錄/user/user_logout.asp
將user_regpost.asp 覆蓋到 powereasy安裝根目錄/reg/user_regpost.asp
拷貝discuz_passport文件夾到Powereasy安裝根目錄
步驟3: 修改discuz_passport裡的config.asp文件部分變量
Discuz_PassportKey="1234567890" '這裡換成你discuz論壇通行證設置的passportkey
Discuz_YourAspWeb_Url="http://localhost:8080/" '這裡換成你的主頁絕對地址或相對地址
Discuz_Bbs_Url="http://localhost/discuz/" '這裡換成你的discuz論壇絕對地址或相對地址
步驟4：
到discuz論壇後台通行證設置開啟通行證
啟用通行證: 是
應用程序 URL 地址: http://localhost:8080/ '這裡換成你的主頁絕對地址或相對地址
通行證私有密匙: 1234567890 '這裡必須與Discuz_Passportkey的值相同
