An Operation used specifically by an HTTPMultiService. An Operation is an individual operation on a service usually corresponding to a single operation on the server side. An Operation can be called either by invoking the function of the same name on the service or by accessing the Operation as a property on the service and calling the send(param1, param2) method. HTTP services also support a sendBody method which allows you to directly specify the body of the HTTP response. If you use the send(param1, param2) method, the body is typically formed by combining the argumentNames property of the operation with the parameters sent. An Object is created which uses the argumentNames[i] as the key and the corresponding parameter as the value.

The exact way in which the HTTP operation arguments is put into the HTTP body is determined by the serializationFilter used.

Descrizione delle proprietà

concurrency

proprietà
concurrency:String[override]

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 3
Versioni runtime: Flash Player 9, AIR 1.1

Value that indicates how to handle multiple calls to the same service operation. The default value is multiple. The following values are permitted:

  • multiple Existing requests are not cancelled, and the developer is responsible for ensuring the consistency of returned data by carefully managing the event stream. This is the default value.
  • single Only a single request at a time is allowed on the operation; multiple requests generate a fault.
  • last Making a request cancels any existing request.



Implementazione
    override public function get concurrency():String
    override public function set concurrency(value:String):void

contentType

proprietà 
contentType:String[override]

Type of content for service requests. The default is application/x-www-form-urlencoded which sends requests like a normal HTTP POST with name-value pairs. application/xml send requests as XML.



Implementazione
    override public function get contentType():String
    override public function set contentType(value:String):void

makeObjectsBindable

proprietà 
makeObjectsBindable:Boolean[override]

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 3
Versioni runtime: Flash Player 9, AIR 1.1

When this value is true, anonymous objects returned are forced to bindable objects.



Implementazione
    override public function get makeObjectsBindable():Boolean
    override public function set makeObjectsBindable(value:Boolean):void

method

proprietà 
method:String[override]

HTTP method for sending the request. Permitted values are GET, POST, HEAD, OPTIONS, PUT, TRACE and DELETE. Lowercase letters are converted to uppercase letters. The default value is GET.



Implementazione
    override public function get method():String
    override public function set method(value:String):void

resultFormat

proprietà 
resultFormat:String[override]

Value that indicates how you want to deserialize the result returned by the HTTP call. The value for this is based on the following:

  • Whether you are returning XML or name/value pairs.
  • How you want to access the results; you can access results as an object, text, or XML.

The default value is object. The following values are permitted:

  • object The value returned is XML and is parsed as a tree of ActionScript objects. This is the default.
  • array The value returned is XML and is parsed as a tree of ActionScript objects however if the top level object is not an Array, a new Array is created and the result set as the first item. If makeObjectsBindable is true then the Array will be wrapped in an ArrayCollection.
  • xml The value returned is XML and is returned as literal XML in an ActionScript XMLnode object.
  • flashvars The value returned is text containing name=value pairs separated by ampersands, which is parsed into an ActionScript object.
  • text The value returned is text, and is left raw.
  • e4x The value returned is XML and is returned as literal XML in an ActionScript XML object, which can be accessed using ECMAScript for XML (E4X) expressions.



Implementazione
    override public function get resultFormat():String
    override public function set resultFormat(value:String):void

rootURL

proprietà 
rootURL:String[override]

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 3
Versioni runtime: Flash Player 9, AIR 1.1

The rootURL is used to compute the URL for an HTTP service operation when the a relative URL is specified for the operation. The directory name of the rootURL is prepended to any relative URLs for the operation. It is typically more convenient to set the baseURL since baseURL specifies the directory name directly whereas rootURL specifies the name of a file whose directory name is prepended. If neither rootURL nor baseURL are set explicitly, the directory name of the .swf file is prepended to relative paths.



Implementazione
    override public function get rootURL():String
    override public function set rootURL(value:String):void

showBusyCursor

proprietà 
showBusyCursor:Boolean[override]

If true, a busy cursor is displayed while a service is executing. The default value is false.



Implementazione
    override public function get showBusyCursor():Boolean
    override public function set showBusyCursor(value:Boolean):void

useProxy

proprietà 
useProxy:Boolean[override]

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.



Implementazione
    override public function get useProxy():Boolean
    override public function set useProxy(value:Boolean):void

Descrizione dei metodi

send

()metodo
override public function send(... args):mx.rpc:AsyncToken

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 3
Versioni runtime: Flash Player 9, AIR 1.1

Executes the http operation. Any arguments passed in are passed along as part of the operation call. If there are no arguments passed, the arguments property of class is used as the source of parameters. HTTP operations commonly take named parameters, not positional parameters. To supply the names for these parameters, you can also set the argumentNames property to an array of the property names.

Parametri

... args — Optional arguments passed in as part of the method call. If there are no arguments passed, the arguments object is used as the source of parameters.

Restituisce
mx.rpc:AsyncToken — AsyncToken Call using the asynchronous completion token pattern. The same object is available in the result and fault events from the token property.
