Answer 1

I had the same issue myself when I first tried this library out. The URI should not have any path in it, just the protocol and host (and port)

Your request URI should look like this:

request.uri = 'http://esbvucmv5.vu.edu.au'

And the Path in the get call would look like this:

request.uri.path = /D2L/2.0/users/

Answer 2

Thanks to the GitHub issue link provided by @Vinay as well as the support of @cjstehno (creator of the helpful http-builder-ng project), I was able to get this working when making calls to Mule.

Normally this should work in http-builder-ng

request.auth.basic(username, password)

But that doesn't work with Mule, and you receive cryptic error messages about authentication, as seen in the question above.

The following workaround resolves this issue when calling Mule.

// Manually generate Base 64 encoding of username and password
String encodedAuthString = "Basic " + ("$username:$password".bytes.encodeBase64().toString())

// Set in the `HttpBuilder.configure` closure
request.headers['Authorization'] = encodedAuthString
