Thinkphp整合ucenter完全可以双向同步登陆、退出、删用户、自动激活DZX用户、发消失、推动态、改密码等的。
ucente同步登陆演试，比如把下面的代码放到你网站的登陆控制器里
$uc = new \Ucenter\Client\UcApi(); 
$uc_user = $uc->uc_get_user($user['username'], 0); //根据用户名检查用户是否存在 
if ($uc_user['0'] > 0) { 
$uc_uid = $uc_user['0']; //记录用户uid 
} else { 
$uc_uid = $uc->uc_user_register($user['username'], '12345678', $user['email'] ? $user['email'] : $uid . '@qq.com'); //注册用户 
} 
if ($uc_uid > 0) { 
echo $uc->uc_user_synlogin($uc_uid); //同步登陆；一定要输出这段代码，你可以跳转时输出$this->success($uc->uc_user_synlogin($uc_uid)); 
} else { 
//todo 错误自己写 
}

/*ucente同步退出演试，比如把下面的代码放到你网站的退出控制器里*/ 
$uc = new \Ucenter\Client\UcApi(); 
echo $uc->uc_user_synlogout(); //同步退出；一定要输出这段代码，你可以跳转时输出$this->success($uc->uc_user_synlogout());

++++++++++++++++++++++++++++++++++++++++++++++其它应用同步登陆、同步退出到本应用+++++++++++++++++++++++++++++++++++++++++++ 
手册地址：http://faq.comsenz.com/library/UCenter/api/api_index.htm 
原理：其它应用登陆、退出、发消息等，都会触发本应用Ucenter\Controller\ApiController.class.php里相应的事件函数，所以你只需要在这个文件里添加你要登陆、退出到本应用的代码就可以了 
比如其它应用登陆时，会触发ApiController.class.php里的synlogin函数，同时会将其它应用的UID和用户名都传过来

//里面的函数如下 
private function synlogin($get, $post) { 
$uid = intval($get['uid']); 
$username = $get['username']; 
//自己根据UID或用户名处理注册，登陆本应用 
}
DZX自动激活方法.txt
打开discuz/api/uc.php，然后找到：
if (($member = getuserbyuid($uid, 1))) { 
dsetcookie('auth', authcode("$member[password]\t$member[uid]", 'ENCODE'), $cookietime); 
}
将上面的代码改为：
if (($member = getuserbyuid($uid, 1))) { 
dsetcookie('auth', authcode("$member[password]\t$member[uid]", 'ENCODE'), $cookietime); 
} else { 
if (!function_exists('uc_get_user')) { 
loaducenter(); 
}

$user = uc_get_user($uid, 1); 
if ($user) { 
$time = time(); 
DB::query("REPLACE INTO " . DB::table('common_member') . " SET `uid`='{$user[0]}' , `username`='{$user[1]}' , `password`='" . md5(random(10)) . "' , `email`='{$user[2]}' , `adminid`='0' , `groupid`='10' , `regdate`='{$time}' , `emailstatus`='0' , `credits`='0' , `timeoffset`='9999'"); 
DB::query("REPLACE INTO " . DB::table('common_member_status') . " SET `uid`='{$user[0]}' , `regip`='{$_G['clientip']}' , `lastip`='{$_G['clientip']}' , `lastvisit`='{$time}' , `lastactivity`='' , `lastpost`='0' , `lastsendmail`='0'"); 
DB::query("REPLACE INTO " . DB::table('common_member_count') . " SET `uid`='{$user[0]}' , `extcredits1`='0' , `extcredits2`='0' , `extcredits3`='0' , `extcredits4`='0' , `extcredits5`='0' , `extcredits6`='0' , `extcredits7`='0' , `extcredits8`='0'"); 
DB::query("REPLACE INTO " . DB::table('common_member_profile') . " SET `uid`='{$user[0]}'"); 
DB::query("REPLACE INTO " . DB::table('common_member_field_forum') . " SET `uid`='{$user[0]}'"); 
DB::query("REPLACE INTO " . DB::table('common_member_field_home') . " SET `uid`='{$user[0]}'"); 
DB::query("UPDATE " . DB::table('common_stat') . " SET `register`=`register`+1 WHERE `daytime` = '" . date('Ymd', $time) . "'"); 
if (($member = getuserbyuid($uid, 1))) { 
dsetcookie('auth', authcode("$member[password]\t$member[uid]", 'ENCODE'), $cookietime); 
} 
} 
}
ucenter 验证码cccc 和出现通信不稳定
若是ucenter通信不稳定的话，时而失败，时而成功 
那可能是你的服务器配置问题（字符串中的 空格 自动转换成 “+”） 
更改方法 
步骤一： 
/source/function/function_core.php 
138行中 
function authcode($string, $operation = 'DECODE', $key = '', $expiry = 0) { 
//添加代码： 
$string=rawurldecode(str_replace(" ","+",$string)); 
步骤二： 
/uc_server/model/base.php 
145行中 
function authcode($string, $operation = 'DECODE', $key = '', $expiry = 0) { 
//添加代码： 
$string=rawurldecode(str_replace(" ","+",$string));

这样就可以让 + 改成空格 
也会解决ucenter 验证码 cccc的问题
