Question

我在服务器上遇到了一个API，但是我收到了此错误消息：

BasicNetwork.performRequest：意外的响应代码500和onErrorResponse：错误：null

我尝试了所有操作，但根本没有工作。请帮忙。

这是创建JSON数组的代码，因为我需要一个参数作为JSON数组。

         private void createJSONOrder() {


    String firstDay = etDate1.getText().toString() + "##" + etStartTime1.getText().toString() + "##" + etEndTime1.getText().toString();
    String secondDay = etDate2.getText().toString() + "##" + etStartTime2.getText().toString() + "##" + etEndTime2.getText().toString();
    selectionItems.add(firstDay);
    selectionItems.add(secondDay);
    String[] blist = new String[selectionItems.s¬ize()];
    Log.e("tag", "array" + blist.length + selectionItems);

    for (int i = 0; i < selectionItems.size(); i++) {
        blist[i] = selectionItems.get(i);
    }
    Log.e("tag", "arrayList" + blist[0]);
    weekdata = new JSONArray();
    for (int i = 0; i < blist.length; i++) {
        weekdata.put(blist[i]);   // create array and add items into that
    }


    Log.e("TAG", "jsonProduct: " + weekdata);
    generataeInvoiceApi();

}

API调用代码：

          private void generataeInvoiceApi() {
    String tag_json_obj = "json_obj_req";
    String url = Constants.GENERATE_INVOICE;


    pBar.setVisibility(View.VISIBLE);

    final SessionManager session = new SessionManager(getActivity());
    final HashMap<String, String> loggedDetail = session.getLoggedDetail();
    HashMap<String, String> params = new HashMap<String, String>();

    params.put("package_id", package_id);
    params.put("week", weekName);
    params.put("weekdata", weekdata.toString());


    Log.e("Tag", "generateInvoiceParam:" + params);

    JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.POST,
            url, new JSONObject(params),
            new Response.Listener<JSONObject>() {

                @Override
                public void onResponse(JSONObject response) {

                    Log.e("generate_response", response.toString());


                    pBar.setVisibility(View.GONE);

                }

            }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            VolleyLog.e("Error: " + error.getMessage());
            // handle error
            pBar.setVisibility(View.GONE);
        }
    }) {

        @Override
        public Map<String, String> getHeaders() throws AuthFailureError {
            HashMap<String, String> headers = new HashMap<String, String>();
            headers.put("Content-Type", "application/json; charset=UTF-8");
            headers.put("Authorization", "Bearer " + loggedDetail.get("api_token"));
            return headers;
        }
    };


    jsonObjReq.setRetryPolicy(new DefaultRetryPolicy(
            100000,
            DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
            DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));


    AppController.getInstance().addToRequestQueue(jsonObjReq, tag_json_obj);
}
  }

我要发送的参数的格式为：

     {weekdata=["2019-04-01##2:15##2:15","2019-04-03##2:15##2:15"], package_id=44, week=Apr 01, 2019}

一切都很好。网址正在iOS端上运行，但无法在我的应用中使用。我该怎么解决？

Answer 1

尝试更改

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

通过

 JSONObject params = new JSONObject();
