HTTPService

Package | mx.rpc.http
Class | public class HTTPService
Inheritance | HTTPService AbstractInvoker flash.events.EventDispatcher
Subclasses | HTTPService

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

You use the HTTPService class to represent an HTTPService object in ActionScript. 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.

Implementation
`public function get showBusyCursor():Boolean`
`public function set showBusyCursor(value:Boolean):void`

url | property |

`url:String`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

Specifies whether to use the Flex proxy service. The default value is `false`. If you do not specify `true` to proxy requests though the Flex server, you must ensure that the player can reach the target URL. You also cannot use destinations defined in the services-config.xml file if the `useProxy` property is set to `false`.

The default value is `false`.

Implementation
`public function get useProxy():Boolean`
`public function set useProxy(value:Boolean):void`

xmlDecode | property |

`xmlDecode:Function`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

ActionScript function used to decode a service result from XML. When the `resultFormat` is an object and the `xmlDecode` property is set, Flex uses the XML that the HTTPService returns to create an Object. If it is not defined the default XMLDecoder is used to do the work.

The function referenced by the `xmlDecode` property must take a flash.xml.XMLNode object as a parameter and should return an Object. It can return any type of object, but it must return something. Returning `null` or `undefined` causes a fault.

The following example shows an <mx:HTTPService> tag that specifies an xmlDecode function:

       <mx:HTTPService id="hs" xmlDecode="xmlDecoder" url="myURL" resultFormat="object" contentType="application/xml">
            <mx:request><source/>
                <obj>{RequestObject}</obj>
            </mx:request>
       </mx:HTTPService>

The following example shows an xmlDecoder function:

    function xmlDecoder (myXML)
    {
     // Simplified decoding logic.
     var myObj = {};
     myObj.name = myXML.firstChild.nodeValue;
     myObj.honorific = myXML.firstChild.attributes.honorific;
     return myObj;
    }

Implementation
`public function get xmlDecode():Function`
`public function set xmlDecode(value:Function):void`

xmlEncode | property |

`xmlEncode:Function`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

ActionScript function used to encode a service request as XML. When the `contentType` of a request is `application/xml` and the request object passed in is an Object, Flex attempts to use the function specified in the `xmlEncode` property to turn it into a flash.xml.XMLNode object If the `xmlEncode` property is not set, Flex uses the default XMLEncoder to turn the object graph into a flash.xml.XMLNode object.

The `xmlEncode` property takes an Object and should return a flash.xml.XMLNode object. In this case, the XMLNode object can be a flash.xml.XML object, which is a subclass of XMLNode, or the first child of the flash.xml.XML object, which is what you get from an `<mx:XML>` tag. Returning the wrong type of object causes a fault. The following example shows an <mx:HTTPService> tag that specifies an xmlEncode function:

      <mx:HTTPService id="hs" xmlEncode="xmlEncoder" url="myURL" resultFormat="object" contentType="application/xml">
            <mx:request><source/>
                <obj>{RequestObject}</obj>
            </mx:request>
       </mx:HTTPService>

The following example shows an xmlEncoder function:

    function xmlEncoder (myObj)
    {
      return new XML("");
    }

Implementation
`public function get xmlEncode():Function`
`public function set xmlEncode(value:Function):void`

Parameters

| `id:String` (default = `null`)`` — The messageId of the invocation to cancel. Optional. If omitted, the last service invocation is canceled.

Returns

| `AsyncToken` — The AsyncToken associated with the call that is cancelled or null if no call was cancelled.

clearResult | () | method |

logout | () | method |

`public function logout():void`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

Logs the user out of the destination. Logging out of a destination applies to everything connected using the same channel as specified in the server configuration. For example, if you're connected over the my-rtmp channel and you log out using one of your RPC components, anything that was connected over my-rtmp is logged out.

Note: Adobe recommends that you use the mx.messaging.ChannelSet.logout() method rather than this method.
