Question

尝试注册用户但收到错误意外的响应代码404，虽然URL正确，参数也正确，我已经在POSTMAN上测试了它并且它工作正常但是当我尝试提出要求：

E / Volley：[19358] BasicNetwork.performRequest：GIVEN URL的意外响应代码404

参数似乎没有附加到网址，但我也提出了自定义请求，但这也不起作用，请帮忙。

注意：唯一的标题是＆＃34; application/x-www-form-urlencoded＆＃34;;

 private void registerUser()
                {
StringRequest stringRequest = new StringRequest(Request.Method.POST, APIReference.USER_REGISTRATION_URL, new Response.Listener<String>() {
                        @Override
                        public void onResponse(String response) {
                            try {
                                JSONObject jsonObject = new JSONObject(response);
                                Toast.makeText(mContext,jsonObject.getString("status"),Toast.LENGTH_LONG).show();
                                showSnackbar(jsonObject.getString("status"));

                                JSONObject object = jsonObject.getJSONObject("response");
                                User user = new User(object.getString("user_id"),

                                        object.getString("user_email"),
                            object.getString("user_phone_no"));

                Toast.makeText(mContext,String.valueOf(jsonObject.getJSONObject("response")),Toast.LENGTH_LONG).show();

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

        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            Log.d("response error : ", String.valueOf(error));
            showSnackbar(String.valueOf(error));
         }
    })

            Map<String, String> params = new HashMap<>();

            params.put("Content-Type", "application/x-www-form-urlencoded,charset=utf-8");
            return params;

        @Override
        public String getBodyContentType() {
            return "application/x-www-form-urlencoded,charset=utf-8";

    VolleySingleton.getInstance(mContext).getRequestQueue().add(stringRequest);

有时JSON网址响应正常，但在Android中，由于超时，它在Volley Library上显示错误。所以你必须设定时间。

在您的Volley Code上添加此代码：

private static final int MY_SOCKET_TIMEOUT_MS = 60000;

 eventoReq.setRetryPolicy(new DefaultRetryPolicy(
            MY_SOCKET_TIMEOUT_MS,
            DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
            DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));

完整代码：

String url = urlhere;
    Log.e("URL", "" + url);

    StringRequest eventoReq = new StringRequest(Request.Method.GET, url,
            new Response.Listener<String>() {
                @Override
                public void onResponse(String response) {
                    Log.e("RESPONSE", response.toString());

                    utils.hideDialog();
                    try {
                        JSONArray j = new JSONArray(response);

                         //code here
                                }

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

                        }

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


                }
            }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            Log.e("Error: ", "" + error.getMessage());
            utils.hideDialog();
            utils.showtoast("Please try again...");

        }
    });
    eventoReq.setRetryPolicy(new DefaultRetryPolicy(
            MY_SOCKET_TIMEOUT_MS,
            DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
            DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
    // Añade la peticion a la cola
    AppController.getInstance(this).addToRequestQueue(eventoReq);
