How to set username and password using RESTEasy client builder?

I have a url which needs authentication (like a browser pop up appears asking username and password.)

enter image description here

Generally, we can use the following format to achieve this:

http://username:[email protected]

Using RESTEasy client builder 

 Client client = ClientBuilder.newClient();
 WebTarget target = client.target("http://url.com");

How to achieve it without having to construct the http://username:[email protected] myself? I've seen if there are any methods which I could use to set it with no luck. Also I'm not sure how these credentials are passed, headers, cookies etc..

Looks like Basic Authentication. If that's the case, you just need to set the Authorization header to Basic base64encode(username:password).

For example:

String credentials = "username:password"
String base64encoded = Base64.getEncoder().encodeToString(credentials.getBytes());
Response response = target.request()
        .header(HttpHeaders.AUTHORIZATION, "Basic " + base64encoded)....

The Base64 class I used is from Java 8. If you're not using Java 8, there are libraries that have Base64 support. Prior to Java 8, there's a com.sun internal Base64 class, but it's advised not to use those.

If you just want to run a quick test (and don't have Java 8 or don't want to go looking for a lib), you can go to this site and just type in your username:password and encode it, then just copy and paste to your code.

For example:

base64encode(username:password) == dXNlcm5hbWU6cGFzc3dvcmQ=
