I couldn’t find any tutorials on how to use Amazon AWS with GroovyWS, so I took a few minutes to figure out how to do it. Here is some sample code:

import groovyx.net.ws.WSClient

def proxy = new WSClient(“http://webservices.amazon.com/AWSECommerceService/AWSECommerceService.wsdl?”, this.class.classLoader)

def req = proxy.create(“com.amazon.webservices.awsecommerceservice._2008_04_07.ItemSearchRequest”)

req.searchIndex = ‘Books’
req.keywords = “Groovy and Grails”

def search = proxy.create(“com.amazon.webservices.awsecommerceservice._2008_04_07.ItemSearch”)

search.AWSAccessKeyId = “your id here”
search.request.add(req)

def res = proxy.ItemSearch(search)

res.getItems().each {it.getItem().each {
println it.getASIN()
}}

If you’ve downloaded the GroovyWS jar and put it in your GROOVY_HOME/lib, that should work. I think it is kinda cool how quick and easy it is you can get something simple working with GroovyWS, but if you are going to be using Amazon Web Services a lot, it is probably easier to grab the Java Library that Amazon provides and use it. Here is the code for using that in Groovy:

import com.amazonaws.a2s.model.*;
import com.amazonaws.a2s.*;

class AmazonSearch {

String key = ‘your key’
String tag = ‘your associates tag’

def doSearch(String keywords) {
AmazonA2S service = new AmazonA2SClient(key, tag)
ItemSearchRequest request = new ItemSearchRequest()
request.searchIndex = ‘Books’
request.keywords = keywords
processRequest(service, request)
}

private processRequest(AmazonA2S service, ItemSearchRequest request) {
ItemSearchResponse response = service.itemSearch(request)
response.getItems()[0].getItem().each {
println it.getASIN()
}
}

static void main(args) {
AmazonSearch search = new AmazonSearch()
search.doSearch(“Groovy and Grails”)
}

}
