通过Volley请求发送身份验证信息 [英] Send authentication information with Volley request

问题描述

在我的Android应用中，我必须调用一个看起来像这样的Web服务

In my Android app I have to call a web service which looks like this

http://mywesite.com/demo/mob/getmenubycategory/1

我正在使用截击发送请求，但结果为VolleyError 401. 我已经覆盖了getParams()方法来添加标题，但是它不起作用.

I am using the volley to send the request but the result is VolleyError 401. I have overridden the getParams() method to add the header, but it is not working.

这是我的代码.

RequestQueue requestQueue = volleySingleton.getRequestQueue();
    requestQueue.add(new JsonObjectRequest(Request.Method.GET, url, new Response.Listener<JSONObject>() {
        @Override
        public void onResponse(JSONObject response) {
            Log.e(TAG, "onResponse = \n " + response.toString());
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            Log.e(TAG, "response error \n" + error.networkResponse.statusCode);
        }
    }) {
        @Override
        protected Map<String, String> getParams() throws AuthFailureError {
            try {
                Map<String, String> map = new HashMap<String, String>();
                String key = "Authorization";
                String encodedString = Base64.encodeToString(String.format("%s:%s", "USERNAME", "Password").getBytes(), Base64.NO_WRAP);
                String value = String.format("Basic %s", encodedString);
                map.put(key, value);
                return map;
            } catch (Exception e) {
                Log.e(TAG, "Authentication Filure" );
            }
            return super.getParams();
        }
    });

当我使用浏览器时，它会显示一个对话框，以输入我的用户名和密码.如何使用Volley发送请求中的用户名和密码.

When I use my browser it shows a dialogue to enter my username and password. How can I send the username and password with the request using Volley.

推荐答案

对于IMHO身份验证，您应覆盖getHeaders而不是getParams，请尝试以下操作:

For authentication, IMHO, you should override getHeaders instead of getParams, please try the following:

@Override
public Map<String, String> getHeaders() throws AuthFailureError {
       Map<String, String> headers = new HashMap<>();                
       String credentials = "username:password";
       String auth = "Basic "
                        + Base64.encodeToString(credentials.getBytes(), Base64.NO_WRAP);
       headers.put("Content-Type", "application/json");
       headers.put("Authorization", auth);
       return headers;
}
