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.

concurrency | property |
concurrency:String[override] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | 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:
multipleExisting 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.singleOnly a single request at a time is allowed on the operation; multiple requests generate a fault.lastMaking a request cancels any existing request.
Implementation
override public function get concurrency():String override public function set concurrency(value:String):voidcontentType | property |
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.
Implementation
override public function get contentType():String override public function set contentType(value:String):voidmakeObjectsBindable | property |
makeObjectsBindable:Boolean[override] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
When this value is true, anonymous objects returned are forced to bindable objects.
Implementation
override public function get makeObjectsBindable():Boolean override public function set makeObjectsBindable(value:Boolean):voidmethod | property |
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.
Implementation
override public function get method():String override public function set method(value:String):voidresultFormat | property |
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:
objectThe value returned is XML and is parsed as a tree of ActionScript objects. This is the default.arrayThe 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.xmlThe value returned is XML and is returned as literal XML in an ActionScript XMLnode object.flashvarsThe value returned is text containing name=value pairs separated by ampersands, which is parsed into an ActionScript object.textThe value returned is text, and is left raw.e4xThe 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.
Implementation
override public function get resultFormat():String override public function set resultFormat(value:String):voidrootURL | property |
rootURL:String[override] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | 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.
Implementation
override public function get rootURL():String override public function set rootURL(value:String):voidshowBusyCursor | property |
useProxy | property |
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.
Implementation

override public function send(... args):mx.rpc:AsyncToken| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | 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.
Parameters
... 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.
|
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.
