Problems with HttpBuilder-NG basic authentication for a step definition

I am having problems implementing HttpBuilder-NG basic authentication for a Cucumber feature step definition using Gradle, Groovy and Junit. I have sucessfully implemented this step definition using Behat/PHP. I have also verified the test using Postman.

Here is the build.gradle file

apply plugin: 'groovy'
apply plugin: 'java'

repositories {
    mavenCentral()
}

dependencies {
    compile 'org.codehaus.groovy:groovy-all:2.4.12'
    compile 'io.github.http-builder-ng:http-builder-ng-core:1.0.2'
    testCompile 'junit:junit:4.12'
    testCompile 'info.cukes:cucumber-groovy:1.2.5'
    testCompile 'info.cukes:cucumber-junit:1.2.5'
}

The github API /user/repos path requires authentication to retrieve the user's repository information but the Get is returning an unAuthorized exception. If I leave out the path I get success but the base URL does not require authentication. Here is the Groovy code:

import static cucumber.api.groovy.EN.*
import cucumber.api.PendingException
import static groovyx.net.http.HttpBuilder.configure
import static groovyx.net.http.util.SslUtils.ignoreSslIssues

Given(~/^I am an authenticated user$/) { ->
    def github = configure {
        ignoreSslIssues execution
        request.uri = 'https://api.github.com'
    request.auth.basic('githubUser', 'githubPassword', false)
    }.get {
        request.uri.path = '/user/repos'
    }
    assert github != null
    println github.dump()
}

And here is the exception I am getting (401):

Solution

It looks like GitHub does provide BASIC support (https://developer.github.com/v3/auth/) but it is non-standard and they suggest creating the Authorization header yourself, which would look something like this:

@Grab('io.github.http-builder-ng:http-builder-ng-core:1.0.2')

import static groovyx.net.http.HttpBuilder.configure
import static groovyx.net.http.util.SslUtils.ignoreSslIssues

def username = 'blah'
def password = 'blah'
def creds = "$username:$password".bytes.encodeBase64()

def github = configure {
    ignoreSslIssues execution
    request.uri = 'https://api.github.com'
    request.headers['Authorization'] = "Basic $creds"
}.get {
    request.uri.path = '/user/repos'
    response.failure { fs, obj->
        println "Status: ${fs.statusCode}"
        fs.headers.each { h->
            println h
        }
    }
}

println github.dump()

However, this presents a problem which you may not have on your end. I have 2-factor authentication enabled on my account so I get the X-GitHub-OTP: required; :2fa-type header back (per the documentation linked above). If you do not have 2-factor you should have what you need.

I added the failure handler to get some additional information about the failure cases - it's not required for the solution.
