[flexcoders] Re: Please Help. Http Service WTH
You would need to have -some- way to access the variables... You
could pass in the variables as parameters to your url-building
function (as I did in the example), or you could directly access
them as properties of ui components. I passed them as parameters in
the example for the sake of modularity, but the choice is up to
you. If your url doesn't require any search parameters, the url
value and service.send() are all you need.

has its method property set to POST.

Then just call buldMyUrl(textinput.text) somewhere, such
as the
click handler for a button or just before you call your
httpservice's send() method.

Re: [flexcoders] Re: Please Help. Http Service WTH
Hi Faisal,
Personally, due to the security restrictions and sandboxing of the
Flash player, I prefer to use a proxy method for HTTPServices:
---
MXML File
---
mx:Script
![CDATA[
public function sendService()
{
var parameters : Object = new Object();
parameters.url = "">
/*
* Alternatively, the URL parameter could be:
* parameters.url = '' +
textInput.text + '/thing/here/doc.html';
*/
parameters.myParam_x = textInput2.text;
parameters.myParam_y = textInput3.text;
parameters.myParam_z = textInput4.text;
myService.send(parameters);
}
public function processServiceResult(_event : Event) :
void
{
//
// This would process the result of the HTTPService call
somehow
//
}
]]
/mx:Script
mx:HTTPService
id="myService"
url=""
resultFormat="e4x"
result="processServiceResult(event)"/
!-- URL Field --
mx:TextInput id="textInput"/
!-- Parameter Fields --
mx:TextInput id="textInput2"/
mx:TextInput id="textInput3"/
mx:TextInput id="textInput4"/
!-- Button to activate the service --
mx:Button click="sendService();"/
===
---
PHP File - myProxy.php
---
?
// Grab the specified URL
$url = "">
$start = true;
for ($_REQUEST as $key = $value)
{
// If the parameter name starts with 'myParam'
if (substr($key, 8) == 'myParam_')
{
if ($start)
{
$start = false;
$url .= '?';
}
else
{
$url .= '';
}
// Add the parameter to the URL String
$url .= $key . '=' . $value;
}
}
// Set the content type
header('Content-type: text/xml');
// Open a connection to the specified URL
$handle = fopen($url, 'r');
if (!$handle)
die('errorFailed to open URL/error');
// Collect the result
while (!feof($handle))
$result .= fread($handle, 8192);
// display the result
die($result);
?

This method is a little longwinded. But the "myProxy.php" is generic
enough to work for any project, and should work for any HTTPService
that you need. This allows you to have a dynamic HTTPService accessing
any resource.
Drop me an email if you have any issues with this sample (The code is
from my head, not a working copy)

Graham Weldon
