Question

我们使用GoogleCloudMessaging.getInstance(context).send(context.getString(R.string.gcm_defaultSenderId) + "@gcm.googleapis.com", mId, mBundle);发送上游消息，但由于我尝试迁移新的fcm概念，我也需要更改它，但还找不到任何文档。

我最好的猜测是使用：

RemoteMessage message = new RemoteMessage.Builder(<?>).setMessageId(mId).setData ...
FirebaseMessaging.getInstance().send(message);

但是什么是Builder作为参数？再一次，找不到api ......

如标题所述，如何使用新的fcm概念发送上游消息？

Answer 1

好吧，我的答案很快。保持问答，以备将来参考。我在https://firebase.google.com/docs/cloud-messaging/android/upstream#sample-send

找到了答案

感谢谷歌智能排除搜索结果In order to show you the most relevant results, we have omitted some entries very similar to the 2 already displayed. If you like, you can repeat the search with the omitted results included.

新的API就像：

FirebaseMessaging fm = FirebaseMessaging.getInstance();
fm.send(new RemoteMessage.Builder(SENDER_ID + "@gcm.googleapis.com")
  .setMessageId(Integer.toString(msgId.incrementAndGet()))
  .addData("my_message", "Hello World")
  .addData("my_action","SAY_HELLO")
  .build());

那么你可以从android应用程序直接将你的消息发送到android设备，这是我做过的简单实现，它对我很有用。

编译android排球库

compile 'com.android.volley:volley:1.0.0'

只需复制粘贴这个简单的功能;）你的生活就像黄油刀一样变得光滑。：D

public static void sendPushToSingleInstance(final Context activity, final HashMap dataValue /*your data from the activity*/, final String instanceIdToken /*firebase instance token you will find in documentation that how to get this*/ ) {


final String url = "https://fcm.googleapis.com/fcm/send";
StringRequest myReq = new StringRequest(Request.Method.POST,url,
        new Response.Listener<String>() {
            @Override
            public void onResponse(String response) {
                Toast.makeText(activity, "Bingo Success", Toast.LENGTH_SHORT).show();
            }
        },
        new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                Toast.makeText(activity, "Oops error", Toast.LENGTH_SHORT).show();
            }
        }) {

    @Override
    public byte[] getBody() throws com.android.volley.AuthFailureError {
        Map<String,String> rawParameters = new Hashtable<String, String>();
        rawParameters.put("data", new JSONObject(dataValue).toString());
        rawParameters.put("to", instanceIdToken);
        return new JSONObject(rawParameters).toString().getBytes();
    };

    public String getBodyContentType()
    {
        return "application/json; charset=utf-8";
    }
    @Override
    public Map<String, String> getHeaders() throws AuthFailureError {
        HashMap<String, String> headers = new HashMap<String, String>();
        headers.put("Authorization", "key="+YOUR_LEGACY_SERVER_KEY_FROM_FIREBASE_CONSOLE);
        return headers;
    }

};

Volley.newRequestQueue(activity).add(myReq);
}

注意如果您要向主题发送消息，则可以将参数 instanceIdToken 更改为 / topics / topicName 。对于组，实现是相同的，但您只需要处理参数。 checkout Firebase documentation and you can pass those parameters. 如果您遇到任何问题，请与我们联系。
