Consuming Outside Web Services

So far, the only web services we have worked with are the ones we built ourselves. That's not the idea behind web services. The idea is that anyone can build them, and anyone can use them as long as they know how to work with them.

There are a couple of great sites on the web that store references to web services for people to work with:

http://www.webservicex.net/WS/default.aspx

http://www.xmethods.com/

The one we will be using can be found at

http://www.aspxpressway.com/maincontent/webservices/piglatin.asmx

This web service will translate a string of text we send it to pig Latin and return it.

For those not familiar with pig Latin, it's a language that moves the first letter from the front of certain words to the end and then adds an "ay" to it.

So if you have a sentence just like this, it would read like this:

So if you avehay a entencesay ustjay ikelay isthay, it ouldway eadray ikelay isthay.

The following example will build an application to do just that. But before you jump in to the example, add the WSDL to the Web Services panel (http://www.aspxpressway.com/maincontent/webservices/piglatin.asmx?WSDL).

//create the listener object
var tranObj:Object = new Object();
//the event
tranObj.click = function(){
myConnector.trigger();
}
//add the event listener to the Button component
translate_butn.addEventListener("click", tranObj);

Now test the movie, place this paragraph in (or one of your own), and click the Translate button. When the results are returned, you should see something like Figure 25.11.

Now that you have seen how to absorb web services created by other people, you might want to start working on some of the major web services on the web, such as the
