thinkphp後臺登陸ajax提交驗證碼怎麽進行判斷

判斷傳過去的驗證碼和cookie裏的驗證碼讓否壹致

具體代碼如下：

check_verify($code) //驗證函數

{

$verify = new

\Think\Verify();

return $verify->check($code);

}

Public function login(){ //登陸

$authcode = trim(I('authcode'));

//獲取前端ajax傳過來的authcode

if ( (

!$this->check_verify($authcode)) ){

$this->ajaxReturn(0,"驗證碼錯誤",0);

}
