我正面临着GCM推送通知的问题.我收到以下错误.

{
  "multicast_id":4630467710672911593,
  "success":0,
  "failure":1,
  "canonical_ids":0,
  "results":[{
      "error":"MismatchSenderId"
  }]
}

以下是代码.任何帮助将非常感激.提前致谢.

public function gcmPush() 
{
    $regId = "APA91bHFcgOssQZEqtdUk3EC1ojwC5-LVG3NPV2bMqKyC9rPymR6StmAbz-N7Ss8fnvruZhWWNrR3lmBqpjQItlu00AKHPbltBclUJF-EfC5qG4CF2xiuYYC0NCf8u5rbiYFk8ARhIT4lY2AEPWzGpl1OtTvQEC0gA"; 
    $registatoin_ids = array($regId); 
    $message = array("msg" => 12345); 

    $this->send_notification($registatoin_ids, $message);
}

public function send_notification($registatoin_ids, $message) 
{
  // Set POST variables
  $url = 'https://android.googleapis.com/gcm/send';         
  define('GOOGLE_API_KEY', 'AIzaSyBavsIgQKo1Nf9wKZ5o_fGvE_6MI52LFR0');
  $fields = array(
    'registration_ids' => $registatoin_ids,
    'data' => $message,
  );
  $headers = array(
   'Authorization: key=' . GOOGLE_API_KEY,
   'Content-Type: application/json'
  );

  // Open connection
  $ch = curl_init();

  // Set the url, number of POST vars, POST data

需要创建javascript确认弹出点击浏览器后退按钮.如果我点击后退按钮,弹出窗口会出现并说"你想要继续？" 如果单击是,则它将重定向到上一页.

我有以下代码,它不符合要求.

if(window.history && history.pushState){ // check for history api support
        window.addEventListener('load', function(){

            // create history states
            history.pushState(-1, null); // back state
            history.pushState(0, null); // main state
            history.pushState(1, null); // forward state
            history.go(-1); // start in main state

            this.addEventListener('popstate', function(event, state){
                // check history state and fire custom events
                if(state = event.state){

                    event = document.createEvent('Event');
                    event.initEvent(state > 0 ? 'next' : 'previous', true, true);
                    this.dispatchEvent(event);

                    var r = confirm("Would you like to save this draft?");
                    if(r==true) {
