android - APS云推送-负载为空

Question

刚刚将我的应用程序升级到 Appcelerator Platform 和 SDK 4.0.0。如果我在 Android 手机上进行全新安装，则会出现以下错误。它的行为就像推送通知正在传入一样，但实际上没有。有什么想法吗？

这是js代码:

var CloudPush = require('ti.cloudpush');
var rc = CloudPush.isGooglePlayServicesAvailable();
if(rc == CloudPush.SUCCESS){
    var flagBgPush = function(){
        bgPush = true;
    };
    CloudPush.retrieveDeviceToken({
        success: deviceTokenSuccess,
        error: function(){}
    });
    CloudPush.addEventListener('trayClickLaunchedApp', flagBgPush);
    CloudPush.addEventListener('trayClickFocusedApp', flagBgPush);
    CloudPush.addEventListener('callback', pushBackgroundCheck);
}

您是否使用 php 脚本来发送通知？

如果是这样，我建议您使用这个脚本对我来说效果很好:

<?php
define('API_ACCESS_KEY', 'YOUR_API_ACESS_KEY' );
$registrationIds = array('DEVICES_TOKENS');
// prep the bundle
$msg = array('android' => array
(
        'alert'         => 'here is a message. message',
        'title'         => 'This is a title. title',
        'vibrate'       => true,
        'sound'         => 'default',
        'icon'  => 'appicon'
));
$fields = array
(
        'registration_ids'      => $registrationIds,
        'data'                  => array( "payload"  => $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;
