Question

希望你们做的很好。我正在从事一项活动，该活动需要从API中解析一些值，而该API需要具有一些参数的POST请求。我已经尽了我所能理解的一切来弄错了，但是我没有什么错，因为它使我除了错误以外没有其他回报。任何帮助将不胜感激。

链接到API文档（2）-https://www.greatsmm.in/api_docs

我正在解析 BALANCE ，请在上述两个链接的底部找到它。

这是我正在使用的方法-

  private void Balance() {

    String url="https://followiz.com/api/v2";
    //here you can choose your method,GET/POST,in this case is Post
    JsonObjectRequest jsonReq = new JsonObjectRequest(Request.Method.POST,
            url , null, new Response.Listener<JSONObject>() {

        @Override
        public void onResponse(JSONObject response) {
            Log.e("Volley response","Response is "+response);
            try {
                Toast.makeText(SMM.this, "The balance is "+response.getInt("balance"), Toast.LENGTH_SHORT).show();
            } catch (JSONException e) {
                Log.e("Exp","The error is "+e);
            }
        }
    }, new Response.ErrorListener() {

        @Override
        public void onErrorResponse(VolleyError error) {
            Log.e("Main Error","The error is "+error);
        }
    }) {
        @Override
        protected Map<String, String> getParams() throws AuthFailureError {
            //send your parameter here

            Map<String, String> parameters = new HashMap<>();
            parameters.put("key", "api_key(deleted because of sec. reasons)");
            parameters.put("action", "balance");


            return parameters;
        }

        //adding header to authenticate
        @Override
        public Map<String, String> getHeaders() throws AuthFailureError {

            Map<String,String> headers = new HashMap<>();
            headers.put("Content-Type", "application/json");
            return  headers;
        }
    };


    mQueue.add(jsonReq);

}

我遇到的错误是-

Response is {"error":"Incorrect request"}
The error is org.json.JSONException: No value for balance

在Android（Volley）中使用参数发出POST请求时出错
