Javascript 如何使用XHR（Ajax）通过GCM发送推送通知

这是我的curl命令，用于通过终端发送通知。它工作正常，但如何在点击按钮时发送通知（使用XHR请求）

---

您可以编写一个php脚本来实现这一目的，只需使用客户端发出一个XHR请求，就像javascript或您选择的任何其他脚本一样。 这是我的php脚本，我几个月前做的，它正在工作

    <?php
    $message = "\": 3,\"title\": \"High score alert!\",\"\": true,\"custom_field\": { \"score\": 51,\"headlines\": \"And now for something completely different...\" }}";
    $apiKey = "Your Key";
    $registrationIDs = array("Registration id");
    $url = 'https://android.googleapis.com/gcm/send';
    // Set POST variables
    $notify = array(
       "alert"=> "great match!",
      "title"=> "Portugal vs. Denmark",
      "icon" => "myicon",
      "badge"=>3,
      "vibrate"=>true,
    "notification"=>"message"
    );

    $fields = array(
    'registration_ids' => $registrationIDs,
    'data' => array( "payload"  => $notify,
    "notification"=>json_encode($notify)));
    $headers = array(
    'Authorization: key=' . $apiKey,
    'Content-Type: application/json'
    );
    $ch = curl_init(); // Open connection
    curl_setopt($ch, CURLOPT_URL, $url );
    // Set the url, number of POST vars, POST data
    curl_setopt($ch, CURLOPT_POST, true );
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true );
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode( $fields ));
    var_dump( $url );
    var_dump($headers);
    var_dump(json_encode( $fields ));
    $result = curl_exec($ch);   // Execute post
    if($result === false)
    die('Curl failed ' . curl_error());
$httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    curl_close($ch);
    $response = json_decode($result);
    print_r($response);
    ?>

thanx，谢谢你的回答，但我不想使用php。有什么方法可以使用javascriptis javascript或你来实现这一点吗？是的，我也可以使用ajax。。。。。有没有办法用ajax做到这一点，jquery@Asim KhanPlease read
