我有一个截取库，提供com.android.volley.ServerError

在我的应用程序中，我尝试将post方法与JSONObjectRequest结合使用，当我尝试使用volley库调用API时，它给出了一个示例。 我把logcat放在了页面的底部，请帮我解决这个错误。我找不到任何解决办法

com.android.volley.ServerError

我在活动中的职能：

您正在url中附加所有参数。我们在volley中使用了getParams方法，您可以以键值对的形式发送参数

请参阅此代码：

private void sendJsonArrayRequestAddOrder(final Context context)
{
    String selectedDate = SelectedDate.split("-")[1].replace(" ","");
    User user = User.getInstance();
    String url = UrlManager.getUrl(this, R.string.AddOrder_url);

    final ProgressDialog pDialog;
    pDialog = new ProgressDialog(this);
    pDialog.setMessage("Loading...");
    pDialog.setCancelable(false);
    pDialog.show();

    Response.Listener<JSONObject> listener = new Response.Listener<JSONObject>()
    {
        @Override
        public void onResponse(JSONObject response)
        {
            try
            {
                JSONObject orderObj = response;
                String OrderCode = response.getString("OrderCode");


            }
            catch (Exception e)
            {
                Log.d("error", e.getMessage());
                e.printStackTrace();
            }
            pDialog.dismiss();

        }
    };

    Response.ErrorListener errorListener = new Response.ErrorListener()
    {
        @Override
        public void onErrorResponse(VolleyError error)
        {
            error.printStackTrace();
            Toast.makeText(getBaseContext(), "error", Toast.LENGTH_LONG).show();
            pDialog.dismiss();
        }
    };

    protected Map<String, String> getParams() {
        Map<String, String> params = new HashMap<String, String>();
  params.put("mobile", user.Mobile);
      params.put("usercarId", SelectedUserCarId);
      params.put("srvIds", SelectedServiceIds);
      params.put("pkgId", SelectedPackageId);
      params.put("ad", SelectedAddress);
      params.put("lat", SelectedLat);
      params.put("lng", SelectedLong);
      params.put("timeId", SelectedTimeId);
      params.put("date", selectedDate);
      params.put("price", String.valueOf((long)Totalprice));

      return params;
      }

    JsonObjectRequest request = new JsonObjectRequest(Request.Method.POST, url,getParams(), listener, errorListener);
    MyApplication.getInstance().addToRequestQueue(request);
}

即使问题没有得到解决，但检查服务器或internet连接可能存在SocketTimeOutException或连接错误，错误将显示在logcat中。

此处不允许使用注释getParams函数@akshay naikcan您可以放置logcat消息，以便我们可以看到问题所在@miladThere显示在日志中。just in StackTrace show server error@ashkay Naik只需点击webbrowser中的url如果出现任何错误，问题在于您尝试使用的Web设备JSONObject请求将第三个参数用作JSONObject，而不是映射。。。此回答中从未定义参数。请添加完整的logcat错误。您应该将Request.Method.POST、url、null中的null替换为您试图发布的数据。在更新的问题@cricket-007中添加了完整的logcat错误。您可以通过应用程序进行过滤吗？其中只有3行显示错误
