php - 从 JsonArrayRequest Volley 发送帖子到服务器不工作

Question

我已经尝试了一些关于将帖子从 JsonArrayRequest volley 发送到服务器的示例，但它不起作用并且日志中没有错误..

所以当我在服务器中调用一个帖子时，帖子无法获取并且在不调用帖子时显示我的数据，但是现在调用帖子时，数据不显示

这是代码

public void JSON_DATA_WEB_CALL() {
            CustomJsonArrayRequest request = new CustomJsonArrayRequest (GET_JSON_DATA_HTTP_URL,
                    new Response.Listener<JSONArray>() {
                        @Override
                        public void onResponse(JSONArray response) {

                            JSON_PARSE_DATA_AFTER_WEBCALL(response);
                        }
                    },
                    new Response.ErrorListener() {
                        @Override
                        public void onErrorResponse(VolleyError error) {

                        }
                    }){
                @Override
                protected Map<String, String> getParams() throws AuthFailureError {
                    HashMap<String, String> params = new HashMap<String, String>();
                    params.put("name", "value");
                    return params;
                }
            };
            requestQueue = Volley.newRequestQueue(this);
            requestQueue.add(request);
    }

这是新类的代码

    public class CustomJsonArrayRequest extends JsonRequest<JSONArray> {

        public CustomJsonArrayRequest(String url, Response.Listener<JSONArray> listener, Response.ErrorListener errorListener) {
            super(Method.POST, url, null, listener, errorListener);
        }

        @Override
        protected Map<String, String> getParams() throws AuthFailureError {
            HashMap<String, String> params = new HashMap<String, String>();
            params.put("name", "value");
            return params;
        }

        @Override
        protected Response<JSONArray> parseNetworkResponse(NetworkResponse response) {
            try {
                String jsonString =
                        new String(response.data, HttpHeaderParser.parseCharset(response.headers));
                return Response.success(new JSONArray(jsonString),
                        HttpHeaderParser.parseCacheHeaders(response));
            } catch (UnsupportedEncodingException e) {
                return Response.error(new ParseError(e));
            } catch (JSONException je) {
                return Response.error(new ParseError(je));
            }
        }
    }

after webcall

public void JSON_PARSE_DATA_AFTER_WEBCALL(JSONArray array){

        for(int i = 0; i<array.length(); i++) {

            GetDataAdapterRiwayat GetDataAdapter2 = new GetDataAdapterRiwayat();

            JSONObject json = null;
            try {

                json = array.getJSONObject(i);

                GetDataAdapter2.setIdJalanRiwayat(json.getString(JSON_ID_JALAN));
                GetDataAdapter2.setNamaJalanRiwayat(json.getString(JSON_NAMA_JALAN));
                GetDataAdapter2.setLatitudeRiwayat(json.getString(JSON_LATITUDE));
                GetDataAdapter2.setLongitudeRiwayat(json.getString(JSON_LONGITUDE));
                GetDataAdapter2.setFotoSebelumRiwayat(json.getString(JSON_FOTO_SEBELUM));
                GetDataAdapter2.setFotoSetelahRiwayat(json.getString(JSON_FOTO_SETELAH));
                GetDataAdapter2.setIdRiwayat(json.getString(JSON_ID_RIWAYAT));

            } catch (JSONException e) {

                e.printStackTrace();
            }
            GetDataAdapter1.add(GetDataAdapter2);
        }

        recyclerViewadapterRiwayat = new RecyclerViewAdapterRiwayat(GetDataAdapter1, this);

        recyclerView.setAdapter(recyclerViewadapterRiwayat);
    }

Answer 1

如果 POST 仍然无效，请使用 GET

例子

CustomJsonArrayRequest request = new CustomJsonArrayRequest (GET_JSON_DATA_HTTP_URL + "?&name=value",
                new Response.Listener<JSONArray>() {
                    @Override
                    public void onResponse(JSONArray response) {

                        JSON_PARSE_DATA_AFTER_WEBCALL(response);
                    }
                },
                new Response.ErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError error) {

                    }
                });

并更改类 CustomJsonArrayRequest

super(Method.POST, url, null, listener, errorListener);

与

super(Method.GET, url, null, listener, errorListener);
