Note: You have to disable this when you use other sites. 注意:使用其他站点时,必须禁用此功能。
Put these lines into the top of your signup.php script: 将这些行放入signup.php脚本的顶部:
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: POST, GET, OPTIONS, PUT, DELETE');
header('Access-Control-Allow-Credentials: true');
