What is 'useProxy' in HTTPService?

There is a property of HTTPService Class: useProxy which is Boolean.
What is the use of this property?

Look at this stackoverflow post:
http://stackoverflow.com/questions/746634/confused-about-httpservices-useproxy-flex-3
There's a few good and applicable descriptions of what this attribute actually means.

Mx:HTTPService tag and mx:headers tag question??

I am trying to send some header information to my servlet via
HTTPService.
I have a <mx:HTTPService> tag and I see that I can have
child tags to pass header information in the request,
<mx:headers> But I am not sure of the syntax, I get parse
errors in the Flex Builder editor. Here is what I have:
<mx:HTTPService id="Test" method="POST" resultFormat="e4x"
contentType="application/xml" url="myServlet" useProxy="false">
<mx:headers>
<!-- NOT SURE OF THE SYNTAX FOR THE DATA I WANT TO SEND
HERE????? ->
</mx:headers>
</mx:HTTPService>
Does someone have an example of the <mx:headers>
section??? I want to pass a value or 2 to my servlet.
Thanks!

You can try building the request object in AS instead of
declaratively
private var getData():void {
var oRequest:Object = {};
oRequest["ui.action"] = ""run";
oRequest["ui.object"] = "whatever";
http_srv.send(oRequest)'

Timeout in resultHandler for HTTPService request

Hello All,
I have a flex application where I am calling to get data in XML format. The data file most likely will contain 10's of thousands of records (in most cases). What I am experiencing is a timeout in my rHandle function (see code snippets below):
Error #1502 A Script has executed for longer than the default timeout period of 15 seconds
My question/problem has 2 parts.
1) how do you disable the timeout?
2) the reading/parsing of the XML data seems to take waaaay too long. Is there a better way?
I put an Alert message at the top of the result handler function and it didnt trigger before the timeout message triggered. I am reading what could be 10's of thousands of records. Is there a better (and FASTER) way to do this than to read in XML format? Currently, no matter what I set the httpservice requests 'timeout' value to doesnt seem to have any effect. I get a timeout after 15 seconds every time. I have tried setting the timeout value to -1 (as documentation suggested) and/or to some very large value (say, 1200...20 minutes). Any and all help is appreciated.   Here is the code and an example of the XML file
private var contactService:HTTPService = new HTTPService();
private var xData:XML;
private var T_Data:ArrayCollection = new ArrayCollection();
private function get_data():void
   contactService.url="data/big_data.xml";
   contactService.format = "e4x";
   contactService.addEventListener(ResultEvent.RESULT, rHandle);
   contactService.requestTimeout = -1;
   contactService.send();
private function rHandle(event:ResultEvent):void
   var i:int;
   xData = event.result as XML;
   for (i=0; i < xData.el.length(); i++)
      var t:Object = new Object();
      t.cid = xData.el[i].cid;
      t.date = xData.el[i].date;
      t.y_axis = xData.el[i].y_axis;
      T_Data.addItem(t);
<mx:PlotChart.....DataProvider="{T_Data}"
   <mx:horizontalAxis>
      <mx:DateTimeAxis />
   </mx:horizontalAxis>
   <mx:verticalAxis>
      <mx:LinearAxis />
   </mx:verticalAxis>
   <mx:series>
      <mx:PlotSeries id=... yField="y_axis" xField="date" />
   </mx:series>
</mx:PlotChart.....
contents of big_data.xml
<xml.....>
<data>
<el><cid>1</cid><date>1243814400982</date><y_axis>10</y_axis></el>
<el><cid>2</cid><date>1243814401982</date><y_axis>12</y_axis></el>
<el><cid>3</cid><date>1243814451982</date><y_axis>44</y_axis></el>
<el><cid>4</cid><date>1243815451730</date><y_axis>21</y_axis></el>
.........(10s of thousands of records like this)....
</data>

Through trial and error, and some investigation, I found that the solution to my problem was to use remoteobject rather than httpservice.
Flex doesnt seem to handle httpservice calls with XX meg feeds very well.

Translate HTTPService request to the plain URI

I'm using following AS code in Flex to get a person's profile:
var httpService:HTTPService = new HTTPService();
httpService.url="http://xyz.com/php/profile.php";
httpService.useProxy=false;
httpService.method="POST";
httpService.resultFormat="e4x";
httpService.addEventListener("result", httpResult);
httpService.addEventListener("fault", httpFault);
var code:Object = new Object();
code.action="getProfile";
code.first_name="John";
code.last_name="Smith";
var ret:AsyncToken = httpService.send(code);
How do I translate the above code into plain HTTP request as you type in a browser's address bar?
I tried the following:
http://xyz.com/php/profile.php?action=getProfile&first_name=John&last_name=Smith
get nothing back. I know I'm using "GET" method in the browser's address bar.

A problem about getEnhancedMicrophone()

In my AIR application
code as below
step 1.
var microphone:Microphone = Microphone.getEnhancedMicrophone();
step 2.
var connection:NetConnection = new NetConnection();
connection.connect("rtmp://localhost:1935/emcs");
step 3.
var httpService:HTTPService = new HTTPService();
httpService.method = "POST";
httpService.useProxy = false;
httpService.resultFormat ="xml";
httpService.url = serverUrl+"/BpMaster?id=1000";
httpService.send();
step 4.
when connection.connected==true ,i publish a NetStream to red5 server, code as below
var nsVoice:NetStream = new NetStream(connection);
nsVoice.client = this;
nsVoice.attachAudio(microphone);
nsVoice.bufferTime = 0;
nsVoice.publish("a_test", "live");
then microphone can not be used anymore, microphone.gain==0 forever,without step3 everythine going well.
please help me solve this problem ,or explain the reason
thanks!

PHP errors in flex

I have an application in PHP and I'm using Flex for the
front. I was wondering how I could transfer information about
errors to flex from php.
So, the questions I am asking are:
What does Flex's HTTPService consider a fault?
Is there a way to write a general wrapper function to manage
httpservices? I tried but flex won't allow me to assign a function
call to the event listener, only a function.

Probably HTTP error codes. You can use the same function in
multiple HTTPServices. If you don't care which one of the
HTTPService thru the error, just use the same function when you
declare the faulthandler for the HTTPService.

What is the proper way to set character encoding in an HTTPService request?

I'm trying to get an HTTPService object's request to have
proper character encoding. If I do nothing, I get "null" inside a
Java servlet when I call getCharacterEncoding() on the request
object. If I do this to my Flex HTTPService:
httpService.contentType = "application/x-www-form-urlencoded;
charset=UTF-8";
then I get a valid character encoding (UTF-8) in the Java
servlet as I should. But the problem is that my HTTPService's POST
parameters are no longer coming along with the request. If I drop
the charset value and set this instead in Flex:
httpService.contentType =
"application/x-www-form-urlencoded";
then I get my POST params in my servlet just fine, but of
course, no charset info.
(For completeness, I am also setting: httpService.method =
"POST"; and httpService.resultFormat = "e4x"; as well as the URL.)
How do I send charset info without interfering with the
transmission of the POST params? This is a serious flaw for anyone
doing UTF-8 content, because most servers are going to assume
ISO-8859-1 if you don't send anything specific. It's interesting
that Flex is actually encoding in UTF-8. I know, because I am
currently working around the problem by intercepting the HTTP
request in my servlet and forcing the character encoding to UTF-8
before binding the params. That's a lousy workaround, though.
Hint to Flex 3 developers: It would be much more preferable
to have a setCharacterEncoding method (or characterEncoding prop)
on the Flex HTTPService.

Hello,
I realize this is an old thread, but the problem still seems
to exist in Flex 3 and I run into it
Unfortunately I don't understand the workaround.
Could someone point out in a bit more detail how this should
be done?
Many thanks indeed,
Peter

HTTPService not reading updated xml, i've been having to refresh the xml in my browser manually

I am calling an HTTPService (id=data2php) which runs a php
script which creates an xml doc and puts it on my server. i then
call another HTTPService (id=feedRequest) which reads the xml doc.
i then try to populate a datagrid with the lastResult of my
HTTPService that reads the xml doc. My issue is that that the
HTTPService which reads the xml doc reads the previous incarnation
of the xml doc, not the newly created one that my HTTPService
(data2php) created. i've been manually going to the xml doc in my
browser and hitting refresh for my feedRequest HTTPService to read
the updated xml.
here is the mxml for the httpservice that reads the xml:
<mx:HTTPService id="feedRequest" url="
http://cfcdi.org/eric/dashboard/php/sales.xml"
result="feedResult(event)" resultFormat="xml" useProxy="false"/>
pretty straight forward.
(actually, once in a while it will read the updated
one)

LittleMuscle,
Instead of binding to the lastResult property, I would
explicitly handle the result and fault events of the HTTPService
(the one that reads the newly created xml doc) and then manually
update an XMLListCollection for use as the datagrid's dp. That way,
you can at least walk through the debugger and see what's going on,
and force the second HTTPService to read only when you're sure the
newly created doc is ready.
Since you said it works sometimes and not other times, it
sounds like it's just a timing problem, sometimes the xml doc is
created quickly enough that the HTTPService grabs the new xml doc,
but if not, it's grabbing the old one. That would be my
guess.

Simultaneous httpservice in the same component

Dear Flexer,
I created an Air application.
On loading my component, I'd to make simultaneous request to my database to load some data to my component.
My component is a form with several comobobox and and text field.
But to do that I have two major problem.
- Sometimes, my form (my component) is loaded but there no information in my text field, perhaps request is not finished? but how to verify that and how to solve.
- Other question, as requests with http service is for different table, one to load sudent, other to load note, other to load teaching , is it possible to do this request in the same php file and to get all thos informations with the same E4X file.
Thanks for help

Hello Regina,
That is what I did, and after your answer I checked everything again and I saw I did all right but when embeding the second ALV view by mistake I embeded the first one again.
Now it is working!
Thanks,

HTTPService call not working

I am not able to call the url for some reason. When i click on submit it says in the browser status bar 'Waiting for localhost...'. The swf file is located at
'http://localhost:8080/web/main.swf' so its on the same domain. Heres the code.
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
    <mx:Panel x="121" y="87" width="422" height="234" layout="absolute">
        <mx:Label text="User Name:"/>
        <mx:TextInput id="username"/>
        <mx:Label text="Password:"/>
        <mx:TextInput id="password"/>
        <mx:Button label="Submit" click="userRequest.send()"/>
    </mx:Panel>
    <mx:HTTPService id="userRequest" url="http://localhost:8080/app/login.do" useProxy="false" method="POST">
        <mx:request xmlns="">
            <username>{username.text}</username>
            <password>{password.text}</password>
        </mx:request>
    </mx:HTTPService>
</mx:Application>
When i hit the url (http://localhost:8080/app/login.do) directly it works. But not via swf file. Any suggestions would be helpful. Thanks.

You might also want to consider using something like Charles Proxy to see what is being transmitted and received. Another thing to consider is if you need a crossdomain.xml file in the locaiton of the service. (likely you do).
If you are using Flash Builder 4 Beta you can also use the Network Monitor which might give some insight.

Dynamic URLs for the mx:HTTPService component

I am looking to make the url property of an mx:HTTPService
component dynamic.
<mx:HTTPService
id="srvDivision"
url="
http://prodserver/prod/get_division.jsp"
useProxy="false" method="POST">
</mx:HTTPService>
I would just like to have an environment property or some
other way where the value is not compiled into the code but derived
at runtime. I am sure this quesiton has been asked before but I
couldn't find a direct answer. I currently use a ResourceBundle
(and properties file) but this is done at compile time. I would
like to change the value of the "
http://prodserver/prod" on the
fly, depending on what environment I am working in...dev or test or
whatever. I am not necessarily looking for the fastest way to do
this, but the right way to do this. Is Data Services the way to
go?

How about when i wanted my HTTPService url to become dynamic
that it gets from an external text file or xml file. Here is an
exampl...
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
xmlns:remoting="com.oreilly.
programmingflex.rpc.*" layout="absolute"
initialize="initializeHandler(event)">
<mx:Script>
<![CDATA[
private function initializeHandler(event:Event):void {
textService.send( );
private function resultHandler(event:Event):void {
textArea.text = String(textService.lastResult);
]]>
</mx:Script>

<mx:HTTPService id="textService" url="
http://123.136.72.41/mashupdemo/ip.xml"
result="resultHandler(event)" />
<mx:TextArea id="textArea" width="500"/>
<mx:VideoDisplay id="vid"
source="{textService.lastResult.subscribers.thevideo}" width="450"
height="338" x="20" y="75" />
</mx:Application>
As you can see my HTTPService URL points to a file named
ip.txt, the file includes my database URL where i will get my files
to be played in my VideoDisplay. Is there anybody who can help me
with this stuff. any reply would be very much appreciated.
thanks!!!

How to get result of HTTPService within a function?

Hello all,
I'm trying to call an HTTPService's send() and get the
resulting data from within a function, and assigning it locally.
Specifically, this is what I want:
private function getData():void {
myRPC.send();
//How do I set the result of myRPC.send to a variable here?
// Neither myRPC.send().result, nor myRPC.lastResult works! I
get null both times!
// But if I set myRPC.result to a separate function that
handles an event, I get the correct data...but not what I want.
var myObject:Object = ???? myRPC.???
<mx:HTTPService result="???" fault="???" id="myRPC"
method="GET" resultFormat="e4x" url="someurl" useProxy="false">
<mx:request xmlns="">
<somedata>hi</somedata>
</mx:request>
</mx:HTTPService>
I am also not sure what to put in 'result' and 'fault' since
I don't want the result/fault to be passed to another
function...could anyone explain this please? Thanks!

Looping SelectedItem values in HttpService to Update Several Rows in Database in Flex

Hi,
My client wanted me to create something that allows certain
DataGrid to display to allow users to edit and update the database
records. The only dilemma I am having here is how to actually
create something from Flex's end to allow users update several rows
of the database at once. Since everything in my datagrid would be
defined as selectedItem whenever a user accesses the entry, how can
I get Flex to recognize each of the updated variables while I
update the database?
Another question is, if I do something like
dg2.selectedItem.id, it would only display the "selectedItem," and
since I intend to loop every single one of the values as such in
the datagrid to be updated, is it possible to do something like dg.
.id? I tried to do this, and I kept on getting errors.
If anyone could refer me to some examples on how to get this
to start, it would be great.
Thanks in advance.
Alice
This is the current code I have:
<mx:HTTPService id="save_scenario" method="POST" url="
http://localhost/save_scenario.php"
useProxy="false">
<mx:request xmlns="">
<scenario_name>{scenario_name}</scenario_name>
<id_no>{dg2.selectedItem.id}</id_no>
<region_name>{dg2.selectedItem.region_name}</region_name>
<population>{dg2.selectedItem.population}</population>
<market>{dg2.selectedItem.market}</market>
</mx:request>
</mx:HTTPService>

Thanks, but I think I will be a little more explicit here
about what I really wanted to know. My impression is that if I have
a DataGrid and that I would like to allow users to edit certain
entries within the actual grid and have all of it saved to the
database, I could use a for loop and just update everything without
paying attention to what has really been updated, but I have been
struggling with how to pass it all to the variables side.
Currently, I could update things one entry a time, by using the
code I provided earlier, but is there a way of which I can have it
all posted to the HTTPService in one go?
Note: I tried using dg.
.id_no in the for loop to iterate over the variables I intend to
post, but I don't think I am allowed to do so, do I?
Alice
Attached is what I used in a PHP script to allow the code
loop around the users' edits, how could I do the similar thing in
Flex by assigning the index variable to something more dynamic?
Attach Code
<?php
if(!isset($_POST['npop'])){
// this is where the user will select how many pops to insert
?>
<form method="post">
<input type="text" name="npop" value="Type in how many
post values">
<input type="submit" value="Continue">
</form>
<?
} else {
if(!isset($_POST['pop'])){
$pop = $_POST['npop'];
// when the user has selected the N number of pops
// its time to create the N input elements
?>
<form method="post">
<input type="hidden" name="npop"
value="<?=$pop;?>">
<input type="hidden" name="pop" value="0">
<?
for($i = 1;$i <= $pop; $i++){
echo "<h3>Pop $i</h3>";
// now comes the 5 input elements..
// add them as u like naming them in the following pattern,
// or whatever prefix
?>
Market: <input type="text" name="a<?=$i;?>"
value="0"><br />
IM_accept: <input type="text" name="b<?=$i;?>"
value="0"><br />
IM_defer: <input type="text" name="c<?=$i;?>"
value="0"/><br />
CR_accept : <input type="text" name="d<?=$i;?>"
value="0"><br />
FC_accept : <input type="text" name="e<?=$i;?>"
value="0"><br />
<?
?>
<input type="Submit" value="Submit form">
</form>
<?
} else {
$pop = $_POST['npop'];
// when the user has submitted the pops,
// they will be inserted to N rows in the table.
for($i = 1; $i <= $pop; $i++){
$a = $_POST['a'.$i]; $b = $_POST['b'.$i]; $c =
$_POST['c'.$i];
$d = $_POST['d'.$i]; $e = $_POST['e'.$i];
$sql = "insert INTO table VALUES('$a', '$b', '$c', '$d',
'$e')" . "\n";
echo $sql;
$myFile = "testFile.txt";
$fh = fopen($myFile, 'a') or die("can't open file");
fwrite($fh, $sql);
fclose($fh);
echo "POPs were recorded. Thank you";
?>

Extending HTTPService breaks mx:request style variables

This is probably something simple I am doing wrong, or lack of understanding, but I have seen the question asked and not answered elsewhere on the interwebs.
I want to extend HTTPService to add a globally set static rootURL for when the SWF is hosted on a CDN:
package com.something.shared.util
    import mx.rpc.http.mxml.HTTPService;
    public class StaticRootHTTPService extends HTTPService
        public static var staticRootURL:String;
        public function StaticRootHTTPService(rootURL:String=null, destination:String=null)
            if((rootURL == null || rootURL == '') && staticRootURL != null && staticRootURL != '') {
                rootURL = staticRootURL;
            super(rootURL, destination);
However when I do this, I can't seem to figure out what to do to get mxml style request definition working again:
    <util:StaticRootHTTPService id="models_edit"
        url="/{models}/{editingItem.id}.xml"
        useProxy="false" method="POST"
        fault="FlexGlobals.topLevelApplication.faultHandler(event);"
        result="saveHandler(event)" showBusyCursor="true"
    >
        <util:request>
//********* THESE BREAK ************
// Could not resolve <_method> to a component implementation.
            <_method>PUT</_method>
// Could not resolve <company> to a component implementation.
            <company>{model_name.text}</company>
// Could not resolve <allowed_streams> to a component implementation.
            <allowed_streams>{streams.value}</allowed_streams>
        </util:request>
    </util:StaticRootHTTPService>
Any quick solution? Thanks.

It is not clear what you are trying to say. This is a Flex 4.1 SDK project using the Flex 3.5 compatibility mode. The 'fx' namespace is not something this project uses currently.
My question is:
When I use HTTPService directly,
        <mx:request>
            <_method>PUT</_method>
            <company>{model_name.text}</company>
            <allowed_streams>{streams.value}</allowed_streams>
        </mx:request>
works as expected, but when I subclass HTTPService,
        <util:request>
            <_method>PUT</_method>
            <company>{model_name.text}</company>
            <allowed_streams>{streams.value}</allowed_streams>
        </util:request>
does NOT work correctly.
How can I get this to work as it does with HTTPService, when I have extended that class?
Thanks.

Assigning httpservice result in an array

Hi all,
I have been trying to call a httpservice and trying to assign
the result in an array as shown below
quote:
Code:
var grade:Array=userRequestReload.lastResult.servicelo
cations as Array;
// this is not working
For the corresponding code the httpservice tag used is:
quote:
Code:
<mx:HTTPService id="userRequestReload" useProxy="false"
method="POST" fault="defaultFault(event)"
result="reloadComboData()" />
I an not able to get the desired outcome. I tried setting the
resultFormat to array also but couldnt succeed.
Hope to get help soon.
Thanks

That question is generalizable to all of the resultFormats
that take XML and convert it to something, like the default
"object'. That conversion is a gray box, and you have little or no
control over it. Reading the doc on the "array" format is not
enlightening.
If you are getting xml from a data source, I advise using
e4x, so that you can control what the heck happens to your data.
