Project is under rebuild. It’s a hard fork of original HttpBuilder-NG

Version 1.* is fully compatible with original project HttpBuilder-NG but on upgraded stack. I.e. supports Groovy 4.* and is built with Java 17.

Quick Overview

This is a modern Groovy DSL for making http requests. It is built against Groovy 4.x, but it doesn’t make any assumptions about which version of Groovy you are using (if they are compatible). The main goal of the client is to allow you to make http requests in a natural and readable way. For example:

//let's configure an http client to make calls to httpbin.org using the default http library
def httpBin = HttpBuilder.configure {
    request.uri = 'http://httpbin.org/'
}

//now let's GET /get endpoint at httpbin.
//This will return a JSON formatted response with an origin property.
def result = httpBin.get {
    request.uri.path = '/get'
}

println("Your ip address is: ${result.origin}")

//Finally lets post a standard http form to httpbin
httpBin.post {
    request.uri.path = '/post'
    request.body = [ input1: 'the first input', input2: 'the second input' ]
    request.contentType = 'application/x-www-form-urlencoded'
}

Hopefully that gives you a general idea of how the client works. It is designed to be compatible with Groovy code annotated with @TypeChecked and @CompileStatic. It also makes use of the @DelegatesTo to provide better IDE support when writing code.
