  添加getHeader

  @Override
          public Map<String, String> getHeaders() throws AuthFailureError {
              HashMap<String, String> headers = new HashMap<String, String>();
              headers.put("token", SharedVariables.TOKEN);
              headers.put("device", SharedVariables.DEVICE_ID);
              headers.put("accept-language", "en-US");
              headers.put("api-version", "1.0");
              return headers;
          }

  此错误意味着您需要进行身份验证 . 您可以这样做，将getHeaders（）添加到您的代码中，所以它是这样的：

  RequestQueue queue = Volley.newRequestQueue(getActivity()); 
  JsonObjectRequest getRequest = new JsonObjectRequest(Request.Method.GET, Server.URL, null,
          new Response.Listener<JSONObject>()
          {
              @Override
              public void onResponse(JSONObject response) {  
                  // display response    
                  hideProgressDialog();
  
              }
          },
          new Response.ErrorListener()
          {
               @Override
               public void onErrorResponse(VolleyError error) {           
                   hideProgressDialog();
             }
          }
  
       @Override
          public Map<String, String> getHeaders() throws AuthFailureError {
          HashMap<String, String> params = new HashMap<String, String>();
          params.put("Content-Type", "application/json");
          String creds = String.format("%s:%s","username","password");
          String auth = "Basic " + Base64.encodeToString(creds.getBytes(), Base64.DEFAULT);
          params.put("Authorization", auth);
          return params;
  
          }
  
      );
  
  queue.add(getRequest);

  HTTP 401表示网站需要身份验证，但未提供或失败 . 您需要对自己进行身份验证 . 未知是否需要提供HTTP基本身份验证，或者Web服务是否需要特殊身份验证，并且只是对其返回值很聪明 .

  如果我们使用 POST instead of GET 或 GET instead of POST 芒，则会发生此错误

  所以，在这一行中将GET改为Post

  JsonObjectRequest getRequest = new JsonObjectRequest(Request.Method.GET, Server.URL, null, new Response.Listener<JSONObject>()

  String http_post() {
  
  RequestQueue MyRequestQueue = Volley.newRequestQueue(Library.this);
  
  //String url = "http://" + "hqplayer" + ":" + Utils.password + "@" + Utils.ip + ":8088/library";
  String url = "http://" + Utils.ip + ":8088/library";
  Log.i(TAG, "HttpPost() <" + url + ">");
  String credentials = "hqplayer:valvole";
  byte[] t = credentials.getBytes();
  byte[] auth = Base64.encode(t, Base64.DEFAULT);
  final String basicAuthValue = new String(auth);
  MyRequestQueue.add(new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {
     @Override
     public void onResponse(String response) {
         Log.i(TAG, "HttpPost() - onResponse() ");               
     }
  }, new Response.ErrorListener() {
     @Override
     public void onErrorResponse(VolleyError error) {
         Log.i(TAG, "HttpPost() - onErrorResponse() ");
         Log.i(TAG, "HttpPost() error <" + error + ">");
     }
  }) {
     @Override
     public Map<String, String> getHeaders() throws AuthFailureError {
         HashMap<String, String> params = new HashMap<String, String>();
         String creds = String.format("%s:%s","hqplayer","valvole");
         String auth = "Basic " + Base64.encodeToString(creds.getBytes(), Base64.DEFAULT);
         params.put("Authorization", auth);
         return params;
      }});
     return null;
  }
