在android java firebase中发送通知时出现排球错误

Question

Volley BasicNetwork.performRequest.BasicNetwork.PerformRequest: 预期的响应代码401 https:/fcm.googleapis.comfcmsend 错误

我不知道这是什么错误，请大家帮忙。

我想得到通知.还是新的向火基消息&volley。请帮助我能够得到聊天通知，但不能用这个。

(PS：原代码有授权与我的firebase密钥，在这里过滤掉了)

首先确保你有服务器密钥从firebase-console -> project-setting -> cloud messaging选项卡。

我有同样的问题，发送通知与 JsonObjectRequest尝试用StringRequest代替.它为我工作。

public void send(String topic,String mes){


    JSONObject notification=new JSONObject();
    JSONObject notificationBody=new JSONObject();
    JSONObject data=new JSONObject();

    try{
        data.put("key","value");
        notificationBody.put("title", "notification title");
        notificationBody.put("body", mes);

        notification.put("to", "/topics/"+topic);
        notification.put("notification", notificationBody);
        notification.put("data", data);

    }
    catch (Exception e){
        e.printStackTrace();
    }


    StringRequest req=new StringRequest(Request.Method.POST, FCM_API, new Response.Listener<String>() {
        @Override
        public void onResponse(String response) {

        }
       },null){


        @Override
        public byte[] getBody() throws AuthFailureError {
            try{
                return notification.toString().getBytes(StandardCharsets.UTF_8);
            }
            catch (Exception e){
                return null;
            }
        }

        @Override
        public Map<String, String> getHeaders() throws AuthFailureError {
            Map<String, String> params = new HashMap<>();
            params.put("Authorization", "key="+serverKey);
            params.put("Content-Type", contentType);
            return params;
        }
    };

    requestQueue.add(req);

}
