Java – http / 1.1 400 error request on httpget with basic authentication

I made an application for httpget

My application uses its own certificate, so the server requires user login For certificates, I used this tutorial

For httpget, I have implemented this implementation:

HttpClient client = new CustClient(getApplicationContext()); // HttpClient that uses my certificates



               // Example send http request
               final String url = "https://ip:port/";// <--in  my implementation i've a right url
               HttpResponse response = null;

               HttpGet httpGet = new HttpGet(url);

               //login
               httpGet.addHeader("Authorization","Basic "+Base64.encodeToString("root:root".getBytes(),Base64.DEFAULT));

               StringBuilder testo = null;
               try {
                response = client.execute(httpGet);
                InputStream contenuto = response.getEntity().getContent();
                BufferedReader rd = new BufferedReader(new InputStreamReader(contenuto));

                String line;
                // Read response until the end
                while ((line = rd.readLine()) != null) { 

                    testo.append(line); 
                }
            } catch (Exception e) {

            }

Why do I make client The execute (httpget) response is an HTTP / 1.1 400 error request Why? Is it correct to authenticate in my code?

Solution

The problem is the authorization header

We must use:

httpGet.addHeader("Authorization",Base64.NO_WRAP));

Substitute:

httpGet.addHeader("Authorization",Base64.DEFAULT));

Because the default parameter adds a "CR" line terminator at the end of the string, it is incorrect if you use it for that title
