这几天公司里要我把三个系统整合起来，一个是自己开发的招商引资系统，一个是前任程序员开发的B2B商务程序，还有一个就是动网BBS，所谓整合就是一站式注册，一站式登陆，一站式注销，前两个系统因为是自己公司开发的，都有开发文档在，所以整合起来比较简单，动网总的来说，验证机制还是比较麻烦的！
一开始我上动网官网上搜索的，找到了一个整合文件，不过个人技术太菜，看了一会放弃了，后来又上CSDN，也没有找到很好的解决方案，那么就只有靠自己了！
这几天我一共试了两种办法，下面先说一下第一种办法，
第一种的思路是这样的，在网站登陆的时候，写Cookies，访问论坛的时候读这个Cookies，如果存在的话，就查询动网的用户表，然后写动网自己的Cookies和Session,实现的步骤是这样的：
1.第一步当然是同步用户表呀。
2.在网站登陆验证页面写下如下语名
'-----------------------------------------------------------------
'同步登陆 修改于（2006-06-28 15:54:00）
'-----------------------------------------------------------------
Response.Cookies("Zjing").Domain = " Zjing. net " 这里域名设置（指定该Cookies只定zjing.com有效）
Response.Cookies("Zjing ").Expires = date()+365
Response.Cookies("Zjing ")("ChinaUserName") = 用户名
Response.Cookies("Zjing ")("ChinaPassword") =Md5加密的密码
'-----------------------------------------------------------------
'同步登陆 修改于（2006-06-28 15:54:00）
'-----------------------------------------------------------------
3.用Dw整站替换的功能将动网所有的
引用内容
Response.Cookies(Dvbbs.Forum_sn).path = Dvbbs.cookiepath
替换为
Response.Cookies("Zjing").Domain = " Zjing. net "
4.新建一个WriteCookies.asp的文件放在动网根目录。将下面这段代码复制进去

上面的代段我就不来分析了，我和大家教一下动网的验证机制吧，动网是Cookies配合Session进行验证的，
Cookies:
Response.Cookies(Dvbbs.Forum_sn).Domain = "Zjing.net" Cookies所在域名
Response.Cookies(Dvbbs.Forum_sn)("StatUserID") = StatUserID 用户在线ID
Response.Cookies(Dvbbs.Forum_sn)("username") = Regname 用户名
Response.Cookies(Dvbbs.Forum_sn)("password") = TruePassWordChina 随机生成的密码，在程序中会和数据库中进行判断
Response.Cookies(Dvbbs.Forum_sn)("userclass") = userclass 用户等级
Response.Cookies(Dvbbs.Forum_sn)("userid") = Dvbbs.UserID 用户名
Response.Cookies(Dvbbs.Forum_sn)("userhidden") = 2 是否在线
Session:
Session(Dvbbs.CacheName & "UserID")
他储存的是一个Xml文档
<xml><userinfo userid="14424" username="用户名" userpassword="密码" useremail="Email" userpost="发贴数" usertopic="主题" usersex="性别" userface="头像" userwidth="头像宽" userheight="头像高" joindate="注册时间" lastlogin="最后登陆时间" cometime="2006-6-28 22:48:39" activetime="活动时间" userlogins="登陆次数" lockuser="0" userclass="版主" usergroupid="3" usergroup="" userwealth="1504" userep="766" usercp="400" userpower="0" userbirthday="" userlastip="220.184.65.190" userdel="0" userisbest="0" userhidden="1" usermsg="" ischallenge="0" usermobile="" titlepic="level18.gif" usertitle="" truepassword="BfVIy4k886ZuD956" usertoday="33|0|0|0|0" usermoney="0" userticket="0" followmsgid="" vip_startime="" vip_endtime="" boardid="0" isuserpermissionall="0"/><agent browser="Microsoft Internet Explorer" version="6.0" platform="Windows 2003" ip="220.184.65.190" lockip="0"/></xml>
5．打开inc/const.asp，在第二行加<!--#include file="../WriteCookies.asp"-->
Const.asp的完整代码为
<!--#Include File="Dv_ClsMain.asp"-->
<!--#include file="../WriteCookies.asp"-->
<%
Set MyBoardOnline=new Cls_UserOnlne
Dvbbs.GetForum_Setting
Dvbbs.CheckUserLogin

到此整合基本上已经可以了,在这里需要特别注意的就是Cookies的域设置，因为我的站比较特别，不是同一个域名，而是有很多的子域名组成的，比如主站www,论坛bbs,所以这里域一定要设置正确，不然三个系统就不能正确读取Cookies了
