Firebase 从 android 应用程序发送 http 云消息

Question

我目前正在使用 http post 请求从 Postman 发送 firebase 云消息。一切正常。我现在正在尝试制作一个简单的 Android 应用程序来发送来自 .但是它不起作用，我得到 InvalidRegistration 或 MissingRegistration 或 com.android.volley.AuthFailureError

在 postman 中，我向 https://fcm.googleapis.com/fcm/send

发送了一个 http post 请求

有 2 个 headers:

Key: 'Authorization'   Value: 'key=AAAAnfdQ2jM:AP....'

Key: 'Content-Type'     Value: application/json

然后在 body 中，使用 raw:

{
"to": "/topics/anytopic",


"data": {
    "my_message": "Hi everyone!",
   }

}

在哪里以及如何将此信息放入我的 volley http post 请求中？

RequestQueue queue = Volley.newRequestQueue(this);
    StringRequest sr = new StringRequest(Request.Method.POST,"https://fcm.googleapis.com/fcm/send", new Response.Listener<String>() {
        @Override
        public void onResponse(String response) {
            Log.d(TAG, "Response: " + response);
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {

        }
    }){
        @Override
        protected Map<String,String> getParams(){
            Map<String,String> params = new HashMap<String, String>();
            return params;
        }

        @Override
        public Map<String, String> getHeaders() throws AuthFailureError {
            Map<String,String> params = new HashMap<String, String>();
            return params;
        }
    };
    queue.add(sr);

我找不到任何这样的例子。

非常感谢。

您需要像这样添加 JSON 正文：

        JSONObject jsonBody = new JSONObject();
    jsonBody.put("to", REUVEN_TOKEN_BE_YOUNG);

    JSONObject jsonObject = new JSONObject();
    jsonObject.put("my_message", "Keep eating healthy!");

    jsonBody.putOpt("data", jsonObject);


    final String requestBody = jsonBody.toString();


    RequestQueue queue = Volley.newRequestQueue(this);
    StringRequest sr = new StringRequest(Request.Method.POST,"https://fcm.googleapis.com/fcm/send", new Response.Listener<String>() {
        @Override
        public void onResponse(String response) {
            Log.d(TAG, "Response: " + response);
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            Log.d(TAG, "That didn't work..." + error);
        }
    }){
        @Override
        protected Map<String,String> getParams(){
            Map<String,String> params = new HashMap<String, String>();

            return params;
        }

        @Override
        public Map<String, String> getHeaders() throws AuthFailureError {
            Map<String,String> params = new HashMap<String, String>();
            params.put("Authorization",BE_YOUNG_APP_KEY);

            return params;
        }



        @Override
        public String getBodyContentType() {
            return "application/json; charset=utf-8";
        }

        @Override
        public byte[] getBody() throws AuthFailureError {
            try {
                return requestBody == null ? null : requestBody.getBytes("utf-8");
            } catch (UnsupportedEncodingException uee) {
                VolleyLog.wtf("Unsupported Encoding while trying to get the bytes of %s using %s", requestBody, "utf-8");
                return null;
            }
        }

    };
    queue.add(sr);
