Android volley如何使用身份验证头和Json对象发送请求

  在Request类中，覆盖 getHeaders() 以发送自定义标头

  要在请求正文中发送参数，您需要覆盖请求类的getParams（）或getBody（）方法

  试试这段代码

  @Override
  public Map<String, String> getHeaders() throws AuthFailureError {
      HashMap<String, String> params = new HashMap<String, String>();
      String creds = String.format("%s:%s","USERNAME","PASSWORD");
      String auth = "Basic " + Base64.encodeToString(creds.getBytes(), Base64.DEFAULT);
      params.put("Authorization", auth);
      return params;
  }

  getHeaders（）和getParams（）方法可以同时用作 Headers 和正文分别发送数据 .

  JsonObjectRequest jsonObjectRequest = new 
                      JsonObjectRequest(Request.Method.GET,
                      url,
                      null,
                      new Response.Listener<JSONObject>() {
                          @Override
                          public void onResponse(JSONObject response) {
                              Log.d(TAG, response.toString());
                          }
                      },
                      new Response.ErrorListener() {
                          @Override
                          public void onErrorResponse(VolleyError error) {
                              Log.d(TAG, error.toString());
                          }
                      }) {
                  @Override
                  public Map<String, String> getHeaders() throws AuthFailureError {
                      HashMap<String, String> headers = new HashMap<>();
  
                      headers.put(headerKey, headerValue);
                      return headers;
                  }
  
                  @Override
                  protected Map<String, String> getParams() throws AuthFailureError {
                      Map<String, String> params = new HashMap<>();
                      params.put(bodyKey, bodyValue);
                      return params;
                  }
              };
              VolleySingleton.getInstance(getActivity()).addToRequestQueue(jsonObjectRequest);
  

  这对我有用!!
