android - Android推送插件注册但未收到任何消息

Question

我正在我的应用程序中为 android 实现推送插件通知，为此，在我的应用程序中实际实现 android 的 phonegap 推送插件之前，我遵循了几个教程

第 1 步）我从 GCM 站点的示例下获得了示例代码并创建了一个“示例 APP”。它与一个tomcat服务器一起工作，即我能够注册>>在后端接收这些注册ID>>将它们存储在mysql中>>向每个注册ID发送消息

第 2 步）然后我尝试在我的“主应用程序”中使用适用于 android 的 phonegap 推送插件。虽然它能够使用 gcm 注册应用程序（获取注册 ID）我无法连接到我的后端 tomcat 服务器（与上面相同，具有相同的发件人 ID），即使我尝试在 mysql 中创建一个示例 regid 然后推送消息到 regId 但设备上未收到消息，尽管步骤 1 的“示例应用程序”仍在接收来自 Tomcat 服务器的消息

这是我的主应用程序 AndroidManifest.xml的代码

Answer 1

嗨，我通过在“Android 的 phonegap push-plugin 通知”提供的 onNotificationGCM(ecb) javascript 方法中的事件回调函数 (ECB) 中添加对服务器的显式调用解决了我自己的问题，现在我能够在前台和后台接收通知

var theUrl = new String("http://<yourUrl>:8080?regId="+e.regid+"&userName=xyz");

                            var xmlHttp = null;

                            xmlHttp = new XMLHttpRequest();
                            xmlHttp.open( "GET", theUrl, false );
                            xmlHttp.send( null );
                            alert(xmlHttp.responseText);

我还了解到 CordovaGCMBroadCastReceiver 和 GCMIntentService 应该“一起”并且在主包（mainfest 标签中指定的包）中，原因是当同一设备存在多播（非折叠）时，多个线程将是创建用于将消息发送到同一设备，然后它们中的任何一个都将用于获取唤醒锁，从而导致死锁情况，当我将 CordovaGCMBroadCastReceiver 和 GCMIntentService 都移动到我的主包（即从 com.plugin.gcm 到 com）时，这又被重新定义了。 votesapp.phonegap（我的清单标签中提到的包）。现在我能够接收到同一设备的多个通知。

注意：此解决方案特定于 phonegap 推送插件代码

Answer 2

@user2845335 我遵循了相同的步骤。我在警报中获得了注册 ID。GCM 在谷歌上注册。如果您回忆服务器上的文件http://www.mydomain.com/index.php，则向设备发送消息非常有效

<html>
<head>
 <title>GCM</title>
</head>
<body>
 <?php
  if(isset($_POST['submit'])){
   $con = mysql_connect("x.x.x.x", "Sqlxxxx","xxxxxxx");
   if(!$con){
    die('MySQL connection failed');
   }

   $db = mysql_select_db("Sqlxxxx");
   if(!$db){
    die('Database selection failed');
   }


   $registatoin_ids = array();
   $sql = "SELECT * FROM android_udid";
   $result = mysql_query($sql, $con);
   while($row = mysql_fetch_assoc($result)){
    array_push($registatoin_ids, $row['registration_id']);
   }

   // Set POST variables
   $url = 'https://android.googleapis.com/gcm/send';

   $message = array("message" => $_POST['message']);
       $fields = array(
           'registration_ids' => $registatoin_ids,
           'data' => $message,
        );

        $headers = array(
             'Authorization: key=mykey',
             'Content-Type: application/json'
         );
         // Open connection
         $ch = curl_init();

         // Set the url, number of POST vars, POST data
         curl_setopt($ch, CURLOPT_URL, $url);

         curl_setopt($ch, CURLOPT_POST, true);
         curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
         curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

         // Disabling SSL Certificate support temporarly
         curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

         curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));

         // Execute post
         $result = curl_exec($ch);
         if ($result === FALSE) {
             die('Curl failed: ' . curl_error($ch));
         }

         // Close connection
         curl_close($ch);
         echo $result;

  }
 ?>
 <form method="post" action="index.php">
  <label>Insert Message: </label><input type="text" name="message" />

  <input type="submit" name="submit" value="Send" />
 </form>
 <?php
if (isset($fields)) {
print_r($fields);
}
?>
</body>
</html>

我仍然不能做的是存储在mysql id注册上

<script>

    url: "http://www.mydomain.com/register.php",
    data:...

</script>
