Ionic Push Android推送通知返回“未定义”消息

我一直试图让Android推送通知在我的应用程序上运行一段时间(iOS已经完成),除了只是通知实际显示在Android设备上之外,还要整理所有内容。

注册设备ID,并推送到GCM服务器似乎都工作正常,但当我测试GCM回复中的消息返回时,我一直收到undefined

将消息推送到GCM时的所有响应都是成功的,正确的设备ID,与之关联的消息ID等等。任何人都能指出正确的方向吗?下面您将看到代码片段,其中只有一个示例“警告”用于显示将要返回的内容,最终将用作“推送”中的通知。

此提醒

alert('message = ' + e.message + ' payload message: ' + e.payload.message +
       ' e payload msgcnt: ' + e.payload.msgcnt + ' e.msg: ' + e.msg);

似乎没有得到任何回报来展示推动。

function onDeviceReady() {
    console.log('deviceready');
    try {
        pushNotification = window.plugins.pushNotification;
        if (device.platform == 'android' || device.platform == 'Android' || device.platform == 'amazon-fireos') {
            console.log('PN register');
            pushNotification.register(successHandler, errorHandler, {
                "senderID": "177718756870",
                "ecb": "onNotification"
            });     // required!
            console.log('after PN register');

        } else {
            console.log('PN register');
            pushNotification.register(tokenHandler, errorHandler, {
                "badge": "true",
                "sound": "true",
                "alert": "true",
                "ecb": "onNotificationAPN"
            }); // required!
            console.log('after PN register');
        }
    }
    catch (err) {
        txt = "There was an error on this page.\n\n";
        txt += "Error description: " + err.message + "\n\n";
        console.log("ERROR", txt);

    }

}

var pushNotification;

// handle GCM notifications for Android
window.onNotification = function(e) {

    console.log('EVENT RECEIVED ' + e.event)
    console.log("regID BEFORE CHECKS = " + e.regid);

    switch( e.event )
    {

        case 'registered':
            if ( e.regid.length > 0)
            {
                console.log("regID = " + e.regid);

                var data =
                {
                    'device_id': e.regid,
                    'platform': device.platform,
                    'os_version': device.version,
                    'app_version': lawnmowerConfig.versionString,
                    'device_model': device.model
                };

                localStorage.setItem('push_data', JSON.stringify(data));
            }
            break;

       case 'message':
           console.log('Inside case message: ' + e.regid)

           if (e.foreground)
           {
               // Add something to play a sound once working
           }
           else
           {    
                if (e.coldstart) {
                    console.log("coldstart");

                }
                else {

                    console.log("not coldstart");

                }
           }

           alert('message = ' + e.message + ' payload message: ' + e.payload.message + ' e payload msgcnt: ' + e.payload.msgcnt + ' e.msg: ' + e.msg);

           break;

           case 'error':
                alert('GCM error = ' + e.msg);

           break;

           default:
                // Testing using these alerts instead
                alert('An unknown GCM event has occurred');

           break;
    }
};

function tokenHandler (result) {
    console.log('push token handler');
    console.log(result);
    var data =
    {
        'device_id': result,
        'platform': device.platform,
        'os_version': device.version,
        'app_version': lawnmowerConfig.versionString,
        'device_model': device.model
    };
    localStorage.setItem('push_data', JSON.stringify(data));
}

function successHandler (result) {

    console.log('success handler push success');
    console.log("result: " + result);
}

function errorHandler (error) {
    console.log('push error');
}

document.addEventListener('deviceready', onDeviceReady, true);

注册设备ID并推送到GCM服务器似乎一切正常,但是当我测试GCM回复中的消息返回时,我一直得到undefined。< / p>

这意味着当你正在测试&#34;消息....是什么&#34;您正在引用尚未定义的变量。在这一行:

alert('message = ' + e.message + ' payload message: ' + e.payload.message +
      ' e payload msgcnt: ' + e.payload.msgcnt + ' e.msg: ' + e.msg);

没有变量e.message。您从服务器发送的数据附加到e.payloade.event的值设置为message。我认为如果您删除e.message,您的问题就可以解决了。类似的东西:

alert('event = ' + e.event + ' payload message: ' + e.payload.message +
      ' e payload msgcnt: ' + e.payload.msgcnt + ' e.msg: ' + e.msg);

注意要检测变量问题(范围和/或声明),请一次调试一个变量。这将帮助您精确识别问题并将其跟踪到其原点。

我建议你使用

alert("Payload message: " + e.payload.message);
