Verifying your identity through session_id

PHP code

账号密码验证成功：                session('uid',100);                $sid=session_id();                $this->ajaxReturn(array("result"=>"1","sessionid"=>$sid));               

The HTML page will save session_id in a cookie named SID

  $.cookie('sid', response.data.sessionid);

Verify PHP, each page request sends SID (SESSION_ID)

      $sid=I('post.sid');        session_id($sid);        $this->ajaxReturn(array("uid"=>session('uid'),"sid"=>"$sid"));

Question: Could not get the session's worth or null
But Sid passed the past.

The session will automatically save the identity SessionID on the client, and each request will also carry the session ID to the server. No additional processing is required. Do not know what you are doing here to define an additional SID cookie.
Another cookie is scoped, do you have the same two request domain?
