php - 使用 PHP 向钛(跨平台)开发的 android 应用程序发送推送通知

Question

要从服务器向 android 应用程序发送推送通知，我使用以下脚本。

<?php
    $message = "hi there";
    $apiKey = "xxxxxxxxxxxx"; 
    $registrationIDs = array("xxxxxxx");
    $url = 'https://android.googleapis.com/gcm/send';   
    // Set POST variables
    $fields = array(
        'registration_ids' => $registrationIDs,
        'data' => array( "message"  => $message,
                         )
                        );
    $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 ));
    $result = curl_exec($ch);   // Execute post 

    if($result === false)
        die('Curl failed ' . curl_error());

    curl_close($ch);
    //return $result;
    // curl_close($ch);          // Close connection
    $response = json_decode($result);
    print_r($response);
?>

此代码适用于 native android 应用程序，但是当我使用上述脚本发送推送通知时，使用钛开发的应用程序，设备收到通知，但带有“NULL”payload。

我想知道，为什么？我的 PHP 脚本有什么问题。

更新

这是我接收通知的代码

// These events monitor incoming push notifications
 CloudPush.addEventListener('callback', function (evt) {
     //Ti.API.info('This is the payload data i got'+JSON.parse(evt.payload));
     Ti.API.log("This is the GCM response "+JSON.stringify(evt)); 
     alert(evt.payload);
     //var payload = JSON.parse(evt.payload);
     //Ti.API.info('This is the message data i got'+payload.message);

 });
 CloudPush.addEventListener('trayClickLaunchedApp', function (evt) {
     Ti.API.info('Tray Click Launched App (app was not running)');
 });
 CloudPush.addEventListener('trayClickFocusedApp', function (evt) {
     Ti.API.info('Tray Click Focused App (app was already running)');
 });

这是回应

[INFO] :   APSCloudPush: receivePayload: null
[INFO] :   APSCloudPush: background: true
[INFO] :   APSCloudPush: queuePayload: null
[INFO] :   APSCloudPush: showTrayNotification
[ERROR] :  APSCloudPush: Payload is null!

Answer 1

上面给出的代码是绝对正确的。我想问题只是关键字有效负载。只需将服务器端脚本中的“消息”一词替换为“有效负载”，如下所示。

    $fields = array(
    'registration_ids' => $registrationIDs,
    'data' => array( "payload"  => $message,
                     )
     );

因为在 Titanium ti.cloudePush 模块内部搜索单词 payload
