Question

我正在尝试使用Volley从Android调用服务器上的ASP.net Web api getTokens POST方法。

我从服务器收到400错误，我认为这是一个错误的请求。

我尝试了几种不同的方法，例如将content-type设置为

import numpy as np
for i in range(1,5):
    data['result_' + str(i)] = np.maximum(data['a_' + str(i)] - data['b_' + str(i)], 0)

。和

headers.put("Content-Type", "application/json; charset=utf-8");

但是我使用它并没有改变。我相信使用Android时应将其设置为application / json。

我在SO上看到过其他文章，其中提到getHeaders Override在某些情况下不会设置标头。

任何人都可以看到问题所在吗？

headers.put("Content-Type", "application/x-www-form-urlencoded");

。

try {




                JSONObject js = new JSONObject();
                try {

                    js.put("client_id", "HKTPEMS");
                    js.put("client_secret", "B83845-9AFDDD-46D7B487D");
                    js.put("grant_type", "password");
                    js.put("username", firstName);
                    js.put("password", password);

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






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