第三方应用从UC账号免激活异步登录Discuz方法

最近刚好需要一个结合UC并使用了DX2.5的方案，发现DX2.5官方只提供允许登录自动激活的功能（这选项在DX管理中心->站长 -> UCENTER设置），等于通过UC注册的账号，仍必须在DX2.5登录一次，才能自动激活账号，这样其它基于UC的其它应用，才能实现异步登录。

以下方法解决第三方应用登录，同时异步登录DX2.5，，已在DX2.5+UC1.6+开发的第三方应用中测试通过。

非官方解决方法：

修改dx2.5目录下的api/uc.php
找到以下代码：function synlogin($get, $post) {
     global $_G;

     if(!API_SYNLOGIN) {
       return API_RETURN_FORBIDDEN;
     }

     header('P3P: CP="CURa ADMa DEVa PSAo PSDo OUR BUS UNI PUR INT DEM STA PRE COM NAV OTC NOI DSP COR"');

     $cookietime = 31536000;
     $uid = intval($get['uid']);
     if(($member = getuserbyuid($uid, 1))) {
       dsetcookie('auth', authcode("$member[password]\t$member[uid]", 'ENCODE'), $cookietime);
     }
   }改为：function synlogin($get, $post) {
     global $_G;

     if(!API_SYNLOGIN) {
       return API_RETURN_FORBIDDEN;
     }

     header('P3P: CP="CURa ADMa DEVa PSAo PSDo OUR BUS UNI PUR INT DEM STA PRE COM NAV OTC NOI DSP COR"');

     $cookietime = 31536000;
     $uid = intval($get['uid']);
     if(($member = getuserbyuid($uid, 1))) {
       dsetcookie('auth', authcode("$member[password]\t$member[uid]", 'ENCODE'), $cookietime);
     }
 /**以下代码是新添加**/
     else{
       $init_arr = explode(',', $_G['setting']['initcredits']);
       $groupid = $_G['setting']['regverify'] ? 8 : $_G['setting']['newusergroupid'];

       C::t('common_member')->insert($uid, $get['username'], md5(random(10)), $get['email'], $_G['clientip'], $groupid, $init_arr);
       C::t('common_member_status')->update($uid, array('lastip' => $_G['clientip'], 'lastvisit' =>TIMESTAMP, 'lastactivity' => TIMESTAMP));
       if(($member = getuserbyuid($uid, 1))) {
         dsetcookie('auth', authcode("$member[password]\t$member[uid]", 'ENCODE'), $cookietime);
       }
     }
 /**到这里新增代码结束**/
   }如果要符合DX2.5后台的自动激活选项，要改成这样：function synlogin($get, $post) {
     global $_G;

     if(!API_SYNLOGIN) {
       return API_RETURN_FORBIDDEN;
     }

     header('P3P: CP="CURa ADMa DEVa PSAo PSDo OUR BUS UNI PUR INT DEM STA PRE COM NAV OTC NOI DSP COR"');

     $cookietime = 31536000;
     $uid = intval($get['uid']);
     if(($member = getuserbyuid($uid, 1))) {
       dsetcookie('auth', authcode("$member[password]\t$member[uid]", 'ENCODE'), $cookietime);
     }
     else{
       if($_G['setting']['fastactivation']){
         $init_arr = explode(',', $_G['setting']['initcredits']);
         $groupid = $_G['setting']['regverify'] ? 8 : $_G['setting']['newusergroupid'];

         C::t('common_member')->insert($uid, $get['username'], md5(random(10)), $get['email'], $_G['clientip'], $groupid, $init_arr);
         C::t('common_member_status')->update($uid, array('lastip' => $_G['clientip'], 'lastvisit' =>TIMESTAMP, 'lastactivity' => TIMESTAMP));
         if(($member = getuserbyuid($uid, 1))) {
           dsetcookie('auth', authcode("$member[password]\t$member[uid]", 'ENCODE'), $cookietime);
         }
       }
     }
   }只是简单实现登录，不保证有没有其它的风险存在。慎用。后果自负。
