Google Cloud Message API通知数据未显示 - PHP

Question

im sending notifications to my clients with PHP. Here is my PHP Code for this

<?php

define( 'API_ACCESS_KEY', 'AIzaSyAYq7KpB5J7x3p3zYyna...' );
$registrationId = array( $_GET['id'] );

$msg = array
(
    'message'   => 'here is a message. message',
    'title'     => 'This is a title. title',
    'subtitle'  => 'This is a subtitle. subtitle'
);
$fields = array
(
    'registration_ids'  => $registrationId,
    'notification'          => $msg
);

$headers = array
(
    'Authorization: key=' . API_ACCESS_KEY,
    'Content-Type: application/json'
);

$ch = curl_init();
curl_setopt( $ch,CURLOPT_URL, 'https://android.googleapis.com/gcm/send' );
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 ) );
$result = curl_exec($ch );
curl_close( $ch );
echo $result;

When i execute the script with my registration id there is notification like this, Notification

Title is Push message Body is The Message

As you can see, Notification title and message body is not equal with mines. How i can fix this ? Thank you.

$msg should be a JSON object, as indicated in the Messaging Concepts and Options

{ "to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...", "data" : { "Nick" : "Mario", "body" : "great match!", "Room" : "PortugalVSDenmark" }, }

For a more detailed discussion regarding Downstream Messaging, you can refer to its documentation page were it discusses various aspects of sending messages.
