RE: [flexcoders] POST vs GET vs SEND ...not the same inside Flex

[Tracy Spratt]

Use HTTPService.  Don't mess with contentType, but send your xml as a
string in a name=value pair. Set the method as post.  Set
resultFormat="e4x".  It will work without any problems,
Tracy

Sample code using HTTPService, e4x, handler function to populate a list
item.  
Also shows usage of AsyncToken.

The DataGrid tag:
<mx:DataGrid id="dg" dataProvider="{_xlcMyListData}" .../>


The HTTPService tag:
<mx:HTTPService id="service" resultFormat="e4x" result="onResult(event)"
fault="..../>

Script block declaration:
import mx.rpc.Events.ResultEvent;
[Bindable]private var _xlcMyListData:XMLListCollection;

Invoke send:
var oRequest:Object = new Object();
oRequest.Arg1 = "value1";
var callToken:AsyncToken = service.send(oRequest);
token.callId = "myQuery1";

Result Handler function:
private function onResult(oEvent:ResultEvent):void  {
  var xmlResult:XML = XML(event.result);                //converts
result Object to XML. can also use "as" operator
  var xlMyListData:XMLList = xmlResult.myListData;      //depends on xml
format, is row data
  _xlcMyListData = new XMLListCollection(xlMyListData); //wrap the
XMLList in a collection
  trace(_xlcMyListData.toXMLString());                  //so you can see
exactly how to specify dataField or build labelFunction
  var callToken:AsyncToken = oEvent.token;
  var sCallId = callToken.callId;                       //"myQuery1"
  switch(sCallId)  {                                    //Process the
result conditionally
    case "myQuery1":
      doQuery2();                                       //do whatever
      break;
    ... 
  }
}//onResult

Subject: [flexcoders] POST vs GET vs SEND ...not the same inside Flex

The more I play with this, the more I am convinced that it is acting
wrong because of Flex. I am watching the Apache server access.log as
the data goes by. And I just can't figure this out. My apologies for
the cross-post with Flash-Tiger group but I haven't heard anything and
thought it might be more appropriate here if Flex is causing the error.

I am working from the example in the Actionscript 3 cookbook chapter
20.13 trying to learn how to properly send XML data to a server-side
script. I have tried this a couple ways but haven't been able to get
past xml parsing errors with the basic HTTPService send. And to
compound matters, I am trying to learn Flex at the same time.

This code is from chapter 20.13 but to get any data to pass I have to
switch it from a .POST to a .GET. From what I have read, the .POST is
the right way. Has anybody been through this? Any advice greatly
appreciated.

var request:URLRequest = new URLRequest( "/saveResults.php" );
// Set the data property to the dataToSave XML instance to send
the XML
// data to the server
request.data= dataToSave;
// Set the contentType to signal XML data being sent
request.contentType = "text/xml";
// Use the post method to send the data
request.method = URLRequestMethod.POST;

// Create a URLLoader to handle sending and loading of the XML data
var loader:URLLoader = new URLLoader( );
// When the server response is finished downloading, invoke
handleResponse

loader.addEventListener( Event.COMPLETE, handleResponse );
// Finally, send off the XML data to the URL
loader.load( request );
}

Thanks,
Imogene
