排球字符串请求在android中没有给出响应

Question

我对 Post 方法使用 Volley String 请求..但它没有给出正确的响应..当我使用 JsonObject 请求时它会给我正确的响应..我很困惑，我不明白字符串有什么问题请求..请任何人都可以帮助我处理字符串请求... 这是我的代码..

      StringRequest requestQueue =Volley.newRequestQueue(MainActivity.this);
      String URL ="http://demoangularaims.azurewebsites.net/api/v1/API_NI_ACD_FILL_COMMON_DDL_SP";

      Log.d(TAG, " url=" + URL);
StringRequest stringRequest = new StringRequest(Request.Method.POST, URL, 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, " error=" + error);

    }
}) {
    @Override
    protected Map<String, String> getParams() throws AuthFailureError {

        LinkedHashMap<String, String> linkmap = new LinkedHashMap<>();
        linkmap.put("p_ENTITY_ID", "2");
        linkmap.put("p_ORGCD", "p01");
        linkmap.put("p_COMPCD", "A0002");
        linkmap.put("p_DIVCD", "");
        linkmap.put("p_USERID", "");
        linkmap.put("p_ACDYR", "");
        linkmap.put("p_TYPE", "ACDYR_DDL");
        linkmap.put("p_FILTER1", "");
        linkmap.put("p_FILTER2", "");
        linkmap.put("p_DEFUNCT", "");

        Log.d(TAG, " MAP=" + linkmap);
        return linkmap;
    }

    @Override
    public Map<String, String> getHeaders() throws AuthFailureError {
        LinkedHashMap<String, String> headers = new LinkedHashMap<>();
        return headers;
    }


};

 requestQueue.add(stringRequest);

}

Answer 1

使用 getBody 而不是 getParams 它会起作用。由于您使用的是 POST 方法，因此您应该添加请求正文。

       @Override
        public byte[] getBody() throws AuthFailureError {
            try {                    
                return stringRequestBody.getBytes("utf-8"); //String Request Body with Encoded
            } catch (UnsupportedEncodingException uee) {
                return null;
            }
        }

Answer 2

试试这个

JsonObjectRequest

RequestQueue requestQueue = Volley.newRequestQueue(MainActivity.this);
String URL = "http://demoangularaims.azurewebsites.net/api/v1/API_NI_ACD_FILL_COMMON_DDL_SP";

JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.POST,
                URL, null, new Response.Listener<JSONObject>() {
            @Override
            public void onResponse(JSONObject response) {
                Log.d("TAG", "JSONObj response=" + response);
            }

        }, new Response.ErrorListener() {

            @Override
            public void onErrorResponse(VolleyError error) {
                VolleyLog.d("TAG", "JSONObj Error: " + error.getMessage());
                //Toast.makeText(getApplicationContext(), error.getMessage(), Toast.LENGTH_SHORT).show();
                // hide the progress dialog
            }
        });

requestQueue.add(jsonObjReq);

Jsonobject 请求输出

D/TAG: JSONObj response={"recordsets":[],"output":{},"rowsAffected":[],"returnValue":0}

字符串请求

RequestQueue requestQueue = Volley.newRequestQueue(MainActivity.this);
String URL = "http://demoangularaims.azurewebsites.net/api/v1/API_NI_ACD_FILL_COMMON_DDL_SP";

StringRequest stringRequest = new StringRequest(Request.Method.POST, URL, new Response.Listener<String>() {
            @Override
            public void onResponse(String response) {
                Log.d("TAG", "String response=" + response);
            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                Log.d("TAG", "String error=" + error);

            }
        });
        requestQueue.add(stringRequest);

字符串请求输出

D/TAG: String response={"recordsets":[],"output":{},"rowsAffected":[],"returnValue":0}
