You use the <mx:HTTPService> tag to represent an HTTPService object in an MXML file. When you call the HTTPService object's send() method, it makes an HTTP request to the specified URL, and an HTTP response is returned. Optionally, you can pass parameters to the specified URL. When you do not go through the server-based proxy service, you can use only HTTP GET or POST methods. However, when you set the useProxy property to true and you use the server-based proxy service, you can also use the HTTP HEAD, OPTIONS, TRACE, and DELETE methods.

Note: Due to a software limitation, HTTPService does not generate user-friendly error messages when using GET.

The <mx:HTTPService> tag accepts the following tag attributes:

 <mx:HTTPService
 Properties
 concurrency="multiple|single|last"
 contentType="application/x-www-form-urlencoded|application/xml"
 destination="DefaultHTTP"
 id="No default."
 method="GET|POST|HEAD|OPTIONS|PUT|TRACE|DELETE"
 resultFormat="object|array|xml|e4x|flashvars|text"
 showBusyCursor="false|true"
 makeObjectsBindable="false|true"
 url="No default."
 useProxy="false|true"
 xmlEncode="No default."
 xmlDecode="No default."
 
 Events
 fault="No default."
 result="No default."
 />

The <mx:HTTPService> tag can have a single <mx:request> tag under which the parameters can be specified.

public function HTTPService(rootURL:String = null, destination:String = null)

언어 버전:

ActionScript 3.0

제품 버전:

Flex 3

런타임 버전:

Creates a new HTTPService. This constructor is usually called by the generated code of an MXML document. You usually use the mx.rpc.http.HTTPService class to create an HTTPService in ActionScript.

매개 변수

	`rootURL:String` (default = `null`) — The URL the HTTPService should use when computing relative URLS.

	`destination:String` (default = `null`) — An HTTPService destination name in the service-config.xml file.

public function initialized(document:Object, id:String):void

언어 버전:

ActionScript 3.0

제품 버전:

Flex 3

런타임 버전:

Flash Player 9, AIR 1.1

Called after the implementing object has been created and all component properties specified on the MXML tag have been initialized. If you create this class in ActionScript and want it to function with validation, you must call this method and pass in the MXML document and the HTTPService's id.

매개 변수

	`document:Object` — The MXML document that created this object.

	`id:String` — The identifier used by `document` to refer to this object. If the object is a deep property on document, `id` is null.
