Re: [flexcoders] Using HTTPService in a function

[Michael Schmalle]

Hi,

You not using and object in send()

http.send("?testID=SomeIDNumber")

do;

http.send({testID:someIDNumber})

PS, It really does help to read the docs, they spell this stuff out.

Peace, Mike

Did you import the type?
 
import mx.rpc.events.ResultEvent;
 
Do you 
have the rpc.swc in the classpath?
 
 
Also, 
to use the MXML tag in ActionScript, be sure to use the mxml subpackage version 
of HTTPService, i.e.
 
import 
mx.rpc.http.mxml.HTTPService;

Thanks Martine, 
I have read from the manuals and tutorials and 
tried to do the following: 
 


private function 
SampleFunction():void{
 var 
http:HTTPService;  http = new 
HTTPService(); http.url = 
"">http://www.domain.com/my_xml.php
";
 http.method="POST"; http.useProxy = 
false; http.showBusyCursor = 
true; http.resultFormat = 
"text";

 http.addEventListener( "result", xmlReceived 
); http.send();
}
 
private function xmlReceived(event:ResultEvent):void{    var 
myXML:String;    myXML = 
event.toString();
 
    // Do something with the 
XML}
 
 
The application cannot compile because it says that 
the ResultEvent Type cannot be found.
I even tried to private function 
xmlReceived(event:mx.rpc.events.ResultEvent):void but it 
doesn't solve the problem. 
The error message I receive is "Type was not found or was not a compile-time constant: 
ResultEvent."
 
 
Thanks 
Emery

  It's because at the 
  point that you do:
  myXML = 
  http.lastResult.toString();
  
  … the result of the 
  service has not yet been received. You need to create an event listener to let 
  you know when the service has completed it's call.
  The event listener 
  will then trigger a result function that you create, and in that function is 
  where you should get the result (myXML = 
  http.lastResult.toString();
  ) and do whatever you 
  want with it.

  in a function
  
  
  
  
  
  Hello Group, 
  
  
  I am new here and seeking help 
  from you. 
  
  I have created a function in my 
  Flex application and would like to use the HTTPService object from retreiving 
  XML data from my webservice (based on PHP). 
  
  All the examples I have seen on 
  the Adobe website use same approach (that I don't like) of binding the object 
  to some controls. 
  
  What I trying to achieve is: 
  Create an HTTP object, instruct that object to retreive a web XML string, 
  store that string locally in a variable. 
  
  Using the code I have provided 
  below, the application gives an error saying that the object is not yet 
  created (null). And if I watch the task bar after the error message (in 
  Firefox), I see that the flash application is accessing the webXML. 
  
  
  What might be 
  wrong?
  
  
  
  
  
  
  
  private function 
  SampleFunction():void{
 var 
  http:HTTPService; var 
  myXML:String;  http = new 
  HTTPService(); http.url = 
  "">
http://www.domain.com/my_xml.php";
 http.method="POST";
 http.useProxy = 
  false; http.showBusyCursor = 
  true; http.resultFormat = 
  "text"; http.send();
  
  
  
  myXML = 
  http.lastResult.toString();
  
  
  
  // Do something with 
  XML
  
  }
