ucenter整合shopnc、tipask、dedecms 实现单点注册登录
1.ucenter介绍
UCenter是Comsenz旗下各个产品之间信息直接传递的一个桥梁,通过UCenter 站长可以无缝整合Comsenz系列产品,实现用户的一站式登录以及社区其他数据的交互。当然可以整合任意程序，只要自己实现接入。
http模式下，同步登陆流程如下：
web1 用client.php中的uc_user_login()去ucenter验证登陆，完成后--->
调用uc_user_synlogin()--->uc_api_post()发送到ucenter下control/user.php的onsynlogin()接口--->
返回 字符串(如下同步登陆参数)----->
通过web1将"; exit(); }

}整合完毕后，会出现个问题，shopnc注册其他两个站点需要先登录一次后才能同步，原因是注册仅仅是把用户数据注册到ucenter用户表中，没有把用户数据注册到各自所属用户表中。问题找到了，如下代码
解决方案：
uc_client/model/user.php 修改
function add_user($username, $password, $email, $uid = 0, $questionid = '', $answer = '', $regip = '') {
$oldp = $password;
$regip = empty($regip) ? $this->base->onlineip : $regip;
$salt = substr(uniqid(rand()), -6);
$password = md5(md5($password).$salt);
$sqladd = $uid ? "uid='".intval($uid)."'," : '';
$sqladd .= $questionid > 0 ? " secques='".$this->quescrypt($questionid, $answer)."'," : " secques='',";
$this->db->query("INSERT INTO ".UC_DBTABLEPRE."members SET $sqladd username='$username', password='$password', email='$email', regip='$regip', regdate='".$this->base->time."', salt='$salt'");
$uid = $this->db->insert_id();
$this->db->query("INSERT INTO ".UC_DBTABLEPRE."memberfields SET uid='$uid'");
//同步注册 dede tipask
$password = md5($oldp);
if($uid)
{
file_get_contents("http://127.0.0.1/extend/ask.php?m=Home&c=Login&a=reg&key=123456&username={$username}&password={$password}&email={$email}&uid={$uid}");
file_get_contents("http://127.0.0.1/extend/dede.php?m=Home&c=Login&a=reg&key=123456&username={$username}&password={$password}&email={$email}&uid={$uid}");
}
return $uid;
}done！
