微信授權(quán)問題

在web開發(fā)者工具調(diào)試就有

沒問題
授權(quán)登陸的頁面
但是到了手機(jī)測(cè)試
就沒有這個(gè)頁面但是也可以獲取openid 這是什么原因？

代碼應(yīng)該是沒問題的，因?yàn)榱硪粋€(gè)項(xiàng)目沒有出現(xiàn)這種問題

  //根據(jù)授權(quán)code獲取用戶id 
public static function weixin(){
  $code=!empty($_GET['code'])?trim($_GET['code']):'';
  if(!$code){

我將 獲取用戶的信息的json數(shù)據(jù) 打印出來
