How to do HTTP authentication in android?

Question

I am checking out the class org.apache.http.auth. Any more reference or example if anyone has?

Answer 1

I've not met that particular package before, but it says it's for client-side HTTP authentication, which I've been able to do on Android using the java.net APIs, like so:

Authenticator.setDefault(new Authenticator(){
    protected PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication("myuser","mypass".toCharArray());
    }});
HttpURLConnection c = (HttpURLConnection) new URL(url).openConnection();
c.setUseCaches(false);
c.connect();

Obviously your getPasswordAuthentication() should probably do something more intelligent than returning a constant.

If you're trying to make a request with a body (e.g. POST) with authentication, beware of Android issue 4326. I've linked a suggested fix to the platform there, but there's a simple workaround if you only want Basic auth: don't bother with Authenticator, and instead do this:

c.setRequestProperty("Authorization", "basic " +
        Base64.encode("myuser:mypass".getBytes(), Base64.NO_WRAP));

Answer 2

For me, it worked,

final String basicAuth = "Basic " + Base64.encodeToString("user:password".getBytes(), Base64.NO_WRAP);

Apache HttpCLient:

request.setHeader("Authorization", basicAuth);

HttpUrlConnection:

connection.setRequestProperty ("Authorization", basicAuth);

Answer 3

You can manually insert http header to request:

HttpGet request = new HttpGet(...);
request.setHeader("Authorization", "Basic "+Base64.encodeBytes("login:password".getBytes()));

Answer 4

Manual method works well with import android.util.Base64, but be sure to set Base64.NO_WRAP on calling encode:

String basicAuth = "Basic " + new String(Base64.encode("user:pass".getBytes(),Base64.NO_WRAP ));
connection.setRequestProperty ("Authorization", basicAuth);

Answer 5

For my Android projects I've used the Base64 library from here:

It's a very extensive library and so far I've had no problems with it.

Answer 6

This works for me

 URL imageUrl = new URL(url);
                    HttpURLConnection conn = (HttpURLConnection) imageUrl
                            .openConnection();
                    conn.setRequestProperty("Authorization", "basic " +
                            Base64.encode("username:password".getBytes()));
                    conn.setConnectTimeout(30000);
                    conn.setReadTimeout(30000);
                    conn.setInstanceFollowRedirects(true);
                    InputStream is = conn.getInputStream();
