【问题描述】：

我尝试使用 pushNotification 注册我的设备，使用演示。 它不起作用。打印“Cordova PushNotification Plugin Demo”和“registring android”并查看警报“OK”（successHandler 功能有效）。问题是“ecb”不起作用。为什么？你能帮帮我吗？

我用 Cordova 安装的插件有：PushPlugin、Device、Notification、InAppBrowser 和 Network Information。

我已经在我的 LG L9 和模拟器上试用过该应用程序。同样的问题。

这是代码：

<script type="text/javascript" charset="utf-8" src="cordova.js"></script>
<script type="text/javascript" charset="utf-8" src="jquery_1.5.2.min.js"></script>
<script type="text/javascript" src="PushNotification.js"></script>        
<script type="text/javascript">
var pushNotification;

document.addEventListener("deviceready", onDeviceReady, false);
// device APIs are available

function onDeviceReady() 
pushNotification = window.plugins.pushNotification;
if (device.platform == 'android' || device.platform == 'Android') 
    $("#app-status-ul").append("<li>registering android</li>");
    window.plugins.pushNotification.register(successHandler, errorHandler, 
        "senderID": "my_id",
        "ecb": "onNotificationGCM"
    ); // required!
 else 
    $("#app-status-ul").append("<li>registering ios</li>");
    pushNotification.register(tokenHandler, errorHandler, 
        "badge": "true",
        "sound": "true",
        "alert": "true",
        "ecb": "onNotificationAPN"
    ); // required!



// handle APNS notifications for iOS

function onNotificationAPN(e) 
if (e.alert) 
    navigator.notification.alert(e.alert);

if (e.sound) 
    var snd = new Media(e.sound);
    snd.play();

if (e.badge) 
    pushNotification.setApplicationIconBadgeNumber(successHandler, e.badge);


// handle GCM notifications for Android

function onNotificationGCM(e) 
navigator.notification.alert(e.event);
switch (e.event) 
case 'registered':
    if (e.regid.length > 0) 
        navigator.notification.alert(e.regid);
        // Your GCM push server needs to know the regID before it can push to this device
        // here is where you might want to send it the regID for later use.
        $("#app-status-ul").append("<li>regID = " + e.regid +"</li>");
        sessionStorage.setItem("deviceId",e.regid);
    
    break;
case 'message':
    // if this flag is set, this notification happened while we were in the foreground.
    // you might want to play a sound to get the user's attention, throw up a dialog, etc.
    if (e.foreground) 
        navigator.notification.alert('--INLINE NOTIFICATION--');
        // if the notification contains a soundname, play it.
        var my_media = new Media("/android_asset/www/" + e.soundname);
        my_media.play();
     else  // otherwise we were launched because the user touched a notification in the notification tray.
        if (e.coldstart) navigator.notification.alert('--COLDSTART NOTIFICATION--');
        else navigator.notification.alert('--BACKGROUND NOTIFICATION--');
    
    navigator.notification.alert(e.payload.message);
    navigator.notification.alert('MESSAGE -> MSGCNT: ' + e.payload.msgcnt);
    break;
case 'error':
    navigator.notification.alert('ERROR -> MSG:' + e.msg);
    break;
default:
    navigator.notification.alert('EVENT -> Unknown, an event was received and we do not know what it is');
    break;



function tokenHandler(result) 
navigator.notification.alert(result, null, 'Alert', 'OK');
sessionStorage.setItem("deviceId", result);
sessionStorage.setItem("notificationServer", "APNS");
// Your iOS push server needs to know the token before it can push to this device
// here is where you might want to send it the token for later use.


function successHandler(result) 
navigator.notification.alert(result, null, 'Alert', 'OK');
sessionStorage.setItem("deviceId", result);
sessionStorage.setItem("notificationServer", "GCM");


function errorHandler(error) 
navigator.notification.alert(error, null, 'Alert', 'OK');


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

     </script>

【问题讨论】：

onNotificationGCM 必须在窗口中有范围。查看 logcat 以显示更多错误

那是？没看懂，能举个例子吗？

您运行插件的平台和设备是什么？注意：PushPlugin 在 IOS 模拟器中不工作，您必须在真机上测试。在 Android 中，您可以使用 google API 目标在模拟器中对其进行测试（包括用于 GCM 工作的 google 服务）

【参考方案1】：

正如 Hanh Le 所说，您需要让 ecb-callback 可以从窗口对象访问

这样

    pushNotification.register(tokenHandler, errorHandler, 
       "badge": "true",
       "sound": "true",
       "alert": "true",
       "ecb": "window.onNotificationAPN"
    ); // required!

然后替换

     function onNotificationAPN(e) 

与

    window.onNotificationAPN = function(e) 

编辑：这是您发布的全部代码，我认为应该可以编辑：

<script type="text/javascript" charset="utf-8" src="cordova.js"></script>
<script type="text/javascript" charset="utf-8" src="jquery_1.5.2.min.js"></script>

【讨论】：

安卓系统呢？我试过这个：window.onNotificationGCM = function(e) - - - 然后我编辑了这个 window.plugins.pushNotification.register(successHandler, errorHandler, "senderID": "my_id", "ecb": "window.onNotificationGCM"); 并再次在这个 plugins.pushNotification.register 中再次使用这个 pushNotification.register，但它们不起作用..

我也尝试过其他组合，但没有。我会等待你的建议。

在 iOS 上，无法在模拟器中测试通知，但在您的 android 设备上它应该可以工作。你是如何发送通知的？如果你的设备注册正确，你能在 logcat 中看到传入的通知吗？

也许我错了。但是使用“onNotificationGCM”功能，他应该打印（使用$("#app-status-ul").append("<li>regID = " + e.regid +"</li>")）注册ID？现在，我正在使用平板电脑编写代码，但无法更改代码。在 logcat 中，我没有看到任何关于“regID”的信息。但是，对于 Android，正确的方法是什么？我会在 13 号之后做进一步的测试。

在 locgat 中我没有看到任何关于“regID”的信息，因为我没有在日志中“打印”id，而是在“ul”中使用 $("#app-status-ul").append(...

【参考方案2】：

您可以将 onNotificationGCM 函数放在控制器之外。这是最适合我的解决方案。

创建外部js文件例如：push.js 将onNotificationGCM 函数粘贴到push.js 中，而不使用任何angularjs API，例如angular.module 或.controller

【参考方案3】：

我已经找到了适用于 iOS 的解决方案。此问题的原因是在PushPlugin.m 中，callback 属性在终止应用程序时设置为nil。结果，- (void)notificationReceived 回调中不满足对line#202 的检查。该问题的解决方法是在每次应用启动时在打开推送通知时实例化 PushPlugin 类。这可以通过在应用启动时注册推送通知插件来完成。 每次应用启动时在 javascript 中调用 pushNotification.register 方法，这将实例化插件并分配适当的 callback 插件。我已将以下代码添加到我的Ionic 应用程序的app.run() 部分

window.plugins.pushNotification.register(successCallback, errorCallback, 
    badge: 'true',
    sound: 'true',
    alert: 'true',
    ecb: 'window.onNotificationAPN')
