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.

An ordered list of the names of the arguments to pass to a method invocation. Since the arguments object is a hashmap with no guaranteed ordering, this array helps put everything together correctly. It will be set automatically by the MXML compiler, if necessary, when the Operation is used in tag form.

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.

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.

The URL that the HTTPService object should use when computing relative URLs.
This property is only used when going through the proxy.
When the useProxy property is set to false, the relative URL is computed automatically
based on the location of the SWF running this application.

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.

public var xmlDecode:Function| Wersja języka: | ActionScript 3.0 |
| Wersja produktu: | Flex 3 |
| Wersje środowiska wykonawczego: | 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.
<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;
}
xmlEncode | właściwość |
public var xmlEncode:Function| Wersja języka: | ActionScript 3.0 |
| Wersja produktu: | Flex 3 |
| Wersje środowiska wykonawczego: | 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("");
}
