Groovy HTTPBuilder Cookies

Groovy's super-convenient HTTPBuilder makes web-scraping a breeze. Surprisingly, it doesn't seem to have a built-in DSL for adding pre-configured cookies to your client's session. That's okay, because they're pretty easy to add (once you plow through the documentation). Here's a quick example:

#!/usr/bin/groovy import groovyx.net.http.HTTPBuilder import org.apache.http.impl.cookie.BasicClientCookie @Grapes([ @Grab(group='org.codehaus.groovy.modules.http-builder', module='http-builder', version='0.5.1') ]) class MyScraper { static http = new HTTPBuilder('http://www.example.com/') static void main(String[] args) { try { run args } catch (e) { e.printStackTrace() } } static run(args) { // add some cookies addCookie domain: 'www.example.com', path: '/', name: 'mycookie', value: 'myvalue' addCookie domain: 'www.example.com', path: '/', name: 'anothercookie', value: 'anothervalue' // make some requests using the cookies def html = http.get(path: '/search', query: [q:'groovy']) // ... } // adds a cookie to the http client // with the specified name and value, and optional domain and path static addCookie(m) { // create the basic cookie object def cookie = new BasicClientCookie(m.name, m.value) // add optional cookie properties m.findAll { k,v -> !(k in ['name', 'value']) }. each { k,v -> cookie[k] = v } // add the new cookie to the client's cookie-store http.client.cookieStore.addCookie cookie } }
