Parse.com推送通知未在android上的后台显示

我正在将Parse.com与Ionic应用程序和PushPlugin一起使用,并尝试使用自定义发件人ID通过GCM实施Parse的推送通知。

当我向所有设备发送消息或使用带有cURL的REST API时, 当应用程序在后台但没有安装android通知时,iOS通知会触发。

这是我尝试使用其余的API First for iOS,它运行良好:

curl -X POST \
  -H "X-Parse-Application-Id: APP-ID" \
  -H "X-Parse-REST-API-Key: API-KEY" \
  -H "Content-Type: application/json" \
  -d '{
        "where": {
          "deviceType": "ios"
        },
        "data": {
          "alert": "Hello World!"
        }
      }' \
  https://api.parse.com/1/push

即使应用关闭或在后台打开,也会收到并显示iOS通知。

现在,当我为Android设备尝试相同的定位时:

curl -X POST \
  -H "X-Parse-Application-Id: APP-ID" \
  -H "X-Parse-REST-API-Key: API-KEY" \
  -H "Content-Type: application/json" \
  -d '{
        "where": {
          "deviceType": "android"
        },
        "data": {
          "alert": "Hello World!"
        }
      }' \
  https://api.parse.com/1/push

设备收到通知并部分登录adb logcat但未显示在通知栏中或以其他方式确认。我尝试将'alert'更改为'message',但这没有效果。

但是,如果我尝试使用Postman或cURL的GCM HTTP API,一切都运行良好:

curl 'https://android.googleapis.com/gcm/send' \
  -H 'authorization: key=API-KEY' \
  -H 'content-type: application/json' \
  -d '{
        "registration_ids" : [
          "DEVICE-REGISTRATION-ID"
        ],
        "data" : {
          "message": "You Go I Go, Buddy!"
        }
      }'

使用GCM API和Parse推送通知API时,记录adb logcat时日志不同:

使用Parse:

I/GCM     (10319): GCM message co.yougoigo.mobile 0:1423318254669687%bd9ff524f9fd7ecd

V/GCMBaseIntentService(11506): Intent service name: GCMIntentService-GCMIntentService-3
D/GCMIntentService(11506): onMessage - context: android.app.Application@251ee33b

使用GCM cURL致电:

有没有人有过将GCM通知用于手机应用程序的经验?

为了使用带有Parse Push的phonegap / cordova PushPlugin,您必须意识到Parse实际上以非标准方式包装它的内容。这导致PushPlugin在应用程序位于前台时接收推送通知,但不在后台处理时接收推送通知。

来自GCMIntentService.java的源代码片段

@Override
protected void onMessage(Context context, Intent intent) {
    Log.d(TAG, "onMessage - context: " + context);

    // Extract the payload from the message
    Bundle extras = intent.getExtras();
    if (extras != null)
    {
        // if we are in the foreground, just surface the payload, else post it to the statusbar
        if (PushPlugin.isInForeground()) {
            extras.putBoolean("foreground", true);
            PushPlugin.sendExtras(extras);
        }
        else {
            extras.putBoolean("foreground", false);

            // Send a notification if there is a message
            if (extras.getString("message") != null && extras.getString("message").length() != 0) {
                createNotification(context, extras);
            }
        }
    }
}

正如您所看到的PushPlugin.isInForeground()检查失败时,它会检查附加软件包上的'message'属性。

2观察:

  1. Parse在通知中不包含“消息”,因此PushPlugin不会调用createNotification(content, extras)
  2. 如果您查看捆绑包的“payload”属性,它会将其包含在比“传统”GCM通知更深的一层,方法是将通知放在带有“数据”键的对象上。
  3. 这是捆绑在JSON中的样子

    { ...
      "payload" : {
        "data" : { 
          "message" : "your message here",
          "title": "your title here",
          ...,
          "customData": { ... }
        }
    }
    

    因此,您必须执行一些自定义逻辑以从包extras.getString("payload")中提取有效内容,然后创建新的JSONObject(文档:http://developer.android.com/reference/org/json/JSONObject.html)。

    而不是检查bundle.getString("message"),您需要检查是否存在payload.data,然后解析消息和标题,并确保它们位于正确的位置,以便createNotification函数通过重新打包捆绑来工作(或创建自己的)。

    我的建议是保持现有代码不变,但是对解析格式化通知单独检查并调用自定义createNotification函数。

    如:

    if (PushPlugin.isInForeground()) {
      extras.putBoolean("foreground", true);
      PushPlugin.sendExtras(extras);
    } else if (extras.getString("message") && extras.getString("message").length() != 0) {
      extras.putBoolean("foreground", false);
      createNotification(context, extras);
    } else {
      JSONObject payload = extras.getString("payload");
      JSONObject data = payload.getJSONObject("data");
      String message = data.getString("alert") //parse puts the message as an alert if you don't use custom json payload
      extras.putString("message", alert)
      createNotification(context, extras)
    }
    

    希望这会有所帮助。老实说,我希望解析只是像其他人一样发送数据,以便它与开箱即用的PushPlugin兼容。
