discuz论坛与其它网站登录注册整合

本文以discuz 7.0.0 php版本的论坛与 .net 2.0的网站注册登录整合为类.
没有采用uc_center或第三方插件.以另类的方式实现.
此方法实现的好处是不用过多了解论坛本身的实现细节,借助论坛自己的登录,注册页面来完成,我们只是获到参数post到这个页面来实现注册及登录过程,修改密码也可以用这个方式,但考虑到修改相对简单,就用直接修改数据库的方式实现.

一、论坛修改的地方

1. 论坛入口修改
a. templates/default/header.htm 修改注册和登录入口到网站
b. forumdata/ templates/1_discuz.tpl.php 修改注册和登录的入口
2. register.php改成如下:
<?php

*/

define('CURSCRIPT', 'viewthread');

require_once './include/common.inc.php';

if($goto == 'findpost') {

$pid = intval($pid);
$ptid = intval($ptid);

if($post = $db->fetch_first("SELECT p.tid, p.dateline, t.special FROM {$tablepre}

posts p LEFT JOIN {$tablepre}threads t USING(tid) WHERE p.pid='$pid'")) {
$sqladd = $post['special'] ? "AND first=0" : '';
$page = ceil($db->result_first("SELECT count(*) FROM {$tablepre}posts WHERE

tid='$post[tid]' AND dateline<='$post[dateline]' $sqladd") / $ppp);
if(!empty($special) && $special == 'trade') {
dheader("Location: viewthread.php?do=tradeinfo&tid=$post[tid]

&pid=$pid");
} else {
dheader("Location: viewthread.php?tid=$post[tid]&page=$page".

(isset($_GET['modthreadkey']) && ($modthreadkey=modthreadkey($post['tid'])) ?

"&modthreadkey=$modthreadkey": '')."#pid$pid");
  }
} else {
         $ptid = !empty($ptid) ? intval($ptid) : 0;
  showmessage('post_check', NULL, 'HALTED');
}
}

$tid = $forum['closed'] < 2 ? $tid : $forum['closed'];

if(empty($tid)) {
showmessage('thread_nonexistence');
}

if(isset($fid) && empty($forum)) {
showmessage('forum_nonexistence', NULL, 'HALTED');
}

@include DISCUZ_ROOT.'./forumdata/cache/cache_viewthread.php';

if($goto == 'lastpost') {

if($tid) {
$query = $db->query("SELECT tid, replies, special FROM {$tablepre}threads

WHERE tid='$tid' AND displayorder>='0'");
} else {
$query = $db->query("SELECT tid, replies, special FROM {$tablepre}threads

WHERE fid='$fid' AND displayorder>='0' ORDER BY lastpost DESC LIMIT 1");
}
if(!$thread = $db->fetch_array($query)) {
showmessage('thread_nonexistence');
}
$page = ceil(($thread['special'] ? $thread['replies'] : $thread['replies'] + 1) /

$ppp);
$tid = $thread['tid'];

require_once DISCUZ_ROOT.'./viewthread.php';
exit();

} elseif($goto == 'newpost') {

$page = max(ceil($db->result_first("SELECT COUNT(*) FROM {$tablepre}posts WHERE

tid='$tid' AND dateline<='$lastvisit'") / $ppp), 1);

require_once DISCUZ_ROOT.'./viewthread.php';
exit();

} elseif($goto == 'nextnewset') {

if($fid && $tid) {
$this_lastpost = $db->result_first("SELECT lastpost FROM {$tablepre}threads

WHERE tid='$tid' AND displayorder>='0'");
if($next = $db->fetch_first("SELECT tid FROM {$tablepre}threads WHERE

fid='$fid' AND displayorder>='0' AND lastpost>'$this_lastpost' ORDER BY lastpost ASC LIMIT

1")) {
   $tid = $next['tid'];
   require_once DISCUZ_ROOT.'./viewthread.php';
   exit();
  } else {
   showmessage('redirect_nextnewset_nonexistence');
  }
} else {
  showmessage('undefined_action', NULL, 'HALTED');
}

} elseif($goto == 'nextoldset') {

if($fid && $tid) {
$this_lastpost = $db->result_first("SELECT lastpost FROM {$tablepre}threads

WHERE tid='$tid' AND displayorder>='0'");
if($last = $db->fetch_first("SELECT tid FROM {$tablepre}threads WHERE

fid='$fid' AND displayorder>='0' AND lastpost<'$this_lastpost' ORDER BY lastpost DESC LIMIT

1")) {
   $tid = $last['tid'];
   require_once DISCUZ_ROOT.'./viewthread.php';
   exit();
  } else {
   showmessage('redirect_nextoldset_nonexistence');
  }
} else {
  showmessage('undefined_action', NULL, 'HALTED');
}

} else {
showmessage('undefined_action', NULL, 'HALTED');
}

?>
修改register.php页面，主要是去掉上面的if判断请求来路

二、网站本身修改的地方
1.登录
a.直接从本站登录：把用户名和密码加密后存入session, 点击导航上论坛链接转到bbslogin.aspx

页面
b.如果是从论坛网站登录。直接请求BBSlogin.aspx登录论坛并打开登录页面。Window.open();

{
存入session
string name = Common.DEncrypt.DESEncrypt.Encrypt(username.Text.Trim().ToString(),

"efdsfdedasf48545111111"); //用户名加密
string pass = Common.DEncrypt.DESEncrypt.Encrypt

(txtPassword.Text.Trim().ToString(), "efdsfdedasf48545111111");//密码加密
Session["name"] = name;
Session["pass"] = pass;
}

{
   //网站登录成功之后，进行论坛登录        用户是从论坛过来的
            if (ViewState["url"].ToString().IndexOf("xxx.com") != -1)
            {
                string u_name = Common.DEncrypt.DESEncrypt.Encrypt

(username.Text.Trim(), "efdsfdedasf48545111111"); //用户名加密
string u_pass = Common.DEncrypt.DESEncrypt.Encrypt

(txtPassword.Text.Trim(), "efdsfdedasf48545111111");//密码加密
Page.ClientScript.RegisterStartupScript(GetType(), "bbskey",

"<script>window.open('/User/BBSLogoin.aspx?n=" + u_name + "&p=" + u_pass +

"');window.location.href='/User/index.aspx'</script>", false);

}
}
{ 登录
protected void Page_Load(object sender, EventArgs e)
    {
        ShowUserInfo();
    }
    public void ShowUserInfo()
    {
        string u_name = Session["name"].ToString();
        string u_pass = Session["pass"].ToString();
        Response.Redirect(SitePath + "User/BBSLogoin.aspx?n=" + u_name + "&p=" + u_pass +

"");
Response.Redirect(SitePath + "login.aspx");
}
}

        }
}
3. 用户密码的修改（直接操作数据库;注意discuz密码加密方式先用新密码a进行一次MD5加密32

位,然后用a+(“discuz_uc_members表中的salt字段的值”)）在进行一次MD5加密

public void BBSPwdUpdate(string name, string pwd)
{
string constr =

"host=121.9.1.1;database=discuz;UserName=dbusername;password=123456";
        string res = GetRegistrerCodeByName(UserName.ToString());
        string pwd1 = Common.StrHelper.Md5(pwd, 32).ToString();
        string pwd2 = Common.StrHelper.Md5((pwd1 + res), 32).ToString();
        string sql = "update cdb_members set password ='" + pwd2 + "' where username = '" +

name + "'";
string sql1 = "update cdb_uc_members set password ='" + pwd2 + "' where username =

'" + name + "'";
        using (MySqlConnection con = new MySqlConnection(constr))
        {
            try
            {
                con.Open();
                MySqlCommand cmd = new MySqlCommand(sql, con);
                MySqlCommand cmd1 = new MySqlCommand(sql1, con);
                cmd.ExecuteNonQuery();
                cmd1.ExecuteNonQuery();
            }
            catch (MySqlException ex)
            {
                throw new Exception(ex.Message);
            }
        }
    }

public string GetRegistrerCodeByName(string name)
{
string constr =

"host=121.9.1.1;database=discuz;UserName=dbusername;password=123456";
        string sql = "select salt from cdb_uc_members where username='" + name + "'";
        string res = "";
        using (MySqlConnection con = new MySqlConnection(constr))
        {
            try
            {
                con.Open();
                MySqlCommand com = new MySqlCommand(sql, con);
                res = com.ExecuteScalar().ToString();
            }
            catch (MySqlException ex)
            {
                throw new Exception(ex.Message);
            }
        }
        return res;
    }

三、mysql远程连接失败解决方法
1。改表法。可能是你的帐号不允许从远程登陆，只能在localhost。这个时候只要在localhost的那

台电脑，登入mysql后，更改 “mysql” 数据库里的 “user” 表里的 “host” 项，从“localhost”

改称“%”
mysql -u root -pvmwaremysql>use mysql;
mysql>update user set host = ‘%’ where user = ‘root’;
mysql>select host, user from user;
2. 授权法。例如
