HTTPService URL

I am working on my first Flex and CF Project. The project
works when I run it locally and on a remote CF server. The problem
I have is with coding.
I currently have variables defined for running locally and
for running on the server. I am using comments to manually change
which variables will be used for local and which ones to use for
deploying to a remote server.
For example,
the server needs a full path (d:\home\name\wwwroot\...)
locally I use (c:\coldfusion8\wwwroot\...).
Local code uses the local CF server
<mx:HTTPService id="getDataFile"
url="
http://localhost:8500/com/xml/movieData.xml"
resultFormat= "object"
result="onResult(event)">
</mx:HTTPService>
remote code uses the full url
<mx:HTTPService id="getDataFile"
url="
http://www.somesite.com/com/xml/movieData.xml"
resultFormat= "object"
result="onResult(event)">
</mx:HTTPService>
I was thinking I should have the code detect if its running
locally or remotely and then select the appropriate variables for
remote or local operation. I would appreciate some feedback on the
best way to make this work.
BTW, I don't like conditional compiles to solve this.

Hello,
I am not shure, but I think you have to use a webserver, with
a folder directing to your desktop. Then you can use something like
that:
http://localhost/Desktop.
Otherwise you can try file:///C://Documents and
Settings/[username]/Desktop/flex/...xml
I hope this will help

Dynamic HTTPService URL

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://yourdomainname.com/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!!!

Are you asking if you can make the URL property of the
HTTPService that points to the textService dynamic?
You can bind the property to some local variable that is
dynamically built:
<mx:HTTPService id="textService" url="{someXMLFilePath}"
result="resultHandler(event)" />
The someXMLFilePath variable can be built in the
initializeHandler ( or where ever you want).

Httpservice url property problem

hello everyone
I need to include non latin characters in my httpservice url property. It points to a file. (http://www.myurl.com/nonLatinCharactersInFilename.xml)And its giving me errors.
When I check the error, the url appears like so: http://www.myurl.com/??????????????????.xml
Im using these character set everywhere in the code and there are no problems except when im sending the httpservice call.
I also have same characters in the result event. and theres no prpblem with that.
Any ideas how I can include these file names in the url property? or is there another way?
In my app the user clicks a list (of file names with non latin characters) and an http service is sent to load the corresponding file to a richEditableText component.
every thing except the non latin character part works fine
any help in the right direction will be appreciated.
thanx

Insert variables from script into HTTPService url

I'm trying to insert values from script into a HTTPService
url. How do I go about doing this? I tried the code below, but it
gives an error. Can anybody help?
<mx:HTTPService
id="httpCall"
url="
http://api.service.com/user/{userName}/list?count={apiCount}&offset={(apiOffset)}&sort={ap iSort}&appkey=1234"
resultFormat="e4x"
result="callHandler(event);"
fault="httpFaultHandler(event);"
showBusyCursor="true"
/>
<mx:Script>
<![CDATA[

private var userName:String = "myName";
private var apiCount:uint = 10;
private var apiOffset:uint = 0;
private var apiSort:String = "desc";

Set the HTTPService properties in an AS function.
<mx:HTTPService id="httpCall" resultFormat="e4x" ...

Using a Variable in HttpService url attribute

I have a dynamic url defined below
public var forecastURL:String = "
http://www.weather.gov/forecasts/xml/SOAP_server/ndfdSOAPclientByDay.php?lat="
+ latitude + "&lon=" + longitude +
"&format=12+hourly&startDate=" + todaysDate +
"&numDays=" + numberDays + ""
I would like to use the var without the {} bind. The compiler
complains if the url is not surrounded in quotes. This should be
simple? How can I use a var within the url attribute without the
bind brackets?
<mx:HTTPService
id="forecastRequest"
url = "{forecastURL}" result="resultHandler(event)"
/>

Not Possible..why don't you use the subtitle box instead of help url?

Best practice to configure HTTPService url

I try to find the best way to set up the url attribute of a
large number of httpService in an application that use different
servlet as data provider.
My idea is to read an external XML file and use the text of
nodes to find the settings for the url attribute.
For example:
External file config.xml contains a node like this
<service1>
http://achille:8080/dbfw/DBSERVICE</service1>
In my <mx:Application> on creationComplete I read the
config.xml file and put the content in a Bindable variable that I
will refer in every component of my application by the syntax
XML(parentApplication.config).service1 and use the text value of
the node to set the url attribut of an httpService.
This is very important because when I install the application
at a customer the service1 url change and I have to set up the
application data provider through the external XML file.
Is there an esier way to do obtain a behavior like that ?
Thank you at all

Hi Louis,
you need to setup a service with clusterware. On both sides: primary and standby.
On primary you start them. On standby the services are also configured but stopped.
In case of switchover or failover, data guard will notice clusterware to bring them up.
You need to use this service name in your clients tnsnames.
Another issue are TCP timeouts, to protect against them you use
outbount_connect_timeout in your sqlnet.ora
Also have a look at

HTTPService URL from configuration file?

Hello,
I have a need/requirement to use some type of configuration file for my FLEX builds. Right now I manually build my FLEX app.
It would be nice to configure the URL for all HTTPService objects in an XML file, but I am unsure where that file would reside or what the XML structure should look like.
I have looked at Flashbuilder4 Bible book but it doesnt cover much.
Does anybody know of any good examples, tutorials, books, code links, demos, etc that show how to configure data access for a FLEX project?? Preferably in XML?
I am a little lost in this area and any help or direction is appreciated.
Thank you!

What I need is a way to rebuild my application to point to a different server. Easily.
I have solutioned this using an XML file.
I ended up doing something similar to this guy:
http://vatsalad.wordpress.com/2010/08/15/how-to-deploy-your-flex-app-to-different-servers- without-hardcoding-the-url/
I created a folder, outside of the "src" folder, called "settings". In it, there is an XML file, I named it "webserviceconfig.xml".
"webserviceconfig.xml" looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<webserviceconfig>
<url>http://subdomain.domain.com:8080/BusinessLayer/MyDataServiceWSDL.asmx/</url>
</webserviceconfig>
When my application initializes, it sets a FLEXGlobal variable to store my server URL, like so:
//set the dynamic server URL address, read XML settings file for server URL
FlexGlobals.topLevelApplication.serverURL = webserviceconfig.url;
<fx:XML id="webserviceconfig" source="settings/webserviceconfig.xml" />
Now I am able to reference this all over my application:
myHTTPService.url = FlexGlobals.topLevelApplication.serverURL + "myWebServiceNameHere";
Now my application server URL is configurable and I no longer need to hardcode that anywhere in my application, except my XML configuration file.
I am glad to finally get this monkey off my back.
Thank you for your help and consideration, Caludiu Ursica.

Capture full httpservice url?

is there a simple way to capture the full url (parameters included) when a httpservice is sent? I'd like to put the url in a variable for later use.

You could look at the url and body properties on the corresponding HTTPRequestMessage and reconstruct the URL (assuming method="GET"). You can get this message from either the asynchronous completion token returned from calling httpService.send(), or via an InvokeEvent's message property by registering an invoke="invokeHandler(event)" listener on <mx:HTTPService>.
If you're not using a server side gateway / proxy, the client-side mx.messaging.channels.DirectHTTPChannel is the class that manages the HTTP request. It sets up the query parameters to append to the url in its mx_internal::createURLRequest() method around line 234:
            var urlVariables:URLVariables = new URLVariables();
            var body:Object = httpMsg.body;
            for (var p:String in body)
                urlVariables[p] = httpMsg.body[p];
            params = urlVariables.toString();

Make HTTPService url 'dynamic'?

What's the best way to pass a parameter to the HTTPService in
the URL? For example, a SessionID or other standard http/url
params.
This would be run-time determined, of course, and couldn't be
hard-coded in the mxml or action-script (though the root of the URL
could).
Thanks in advance,
AJ

Yes (I'm going to mark that as the answer).
The key to me was setting that var as bindable and using the
HTTPUtil class to retrieve the value from the parameters on the
html (owner) page's url. Then the creationComplete() function
actually does some work
before doing the HTTPService.send().
Thanks for taking the time to reply. I've posted a few things
(that I don't see totally out of the ordinary), and it seems to be
a bit of a "cold" forum at times. :(

Insert control text property inside httpservice url

I am trying to insert a DateField.text property inside of the
url field for HTTPService in the script portion. I have
successfully tested with setting the url field with a location and
calling the .send() for results with a button. How do I base the
url off of a variable? Here is my code I am using to call the
HTTPService and this works if I set the full line.
public function changeDate():void {
srv.url = "
http://mydomain.com/temp/2008-03-21.xml";
srv.send();
I am trying to pull the text property from a DateField with
an id of dF. This fails though.What do I need to correct?
public function changeDate():void {
srv.url = "'
http://mydomain.com/temp/' +
{dF.text} + '.xml'";
srv.send();

Ok, thank you for the help. I got it working!
Here was the final function.
public function changeDate():void {
srv.url = "
http://mydomain.com/temp/" +
dF.text + ".xml";
srv.send();
}

HTTPService url property

Hi,
I have a folder on the desktop named flex which has an xml
file .
I am trying to use HTTPService and wanted to specify the url
property so that I can access the xml file.
Could someone plz help me with this.

Hello,
I am not shure, but I think you have to use a webserver, with
a folder directing to your desktop. Then you can use something like
that:
http://localhost/Desktop.
Otherwise you can try file:///C://Documents and
Settings/[username]/Desktop/flex/...xml
I hope this will help

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?

Using HTTPService to import data from a XML file

Hello there!
I'm having some problem's with this import... If anyone can
help, I would appreciate it!
I'm using this type of information as data source:
public var dataCollection:ArrayCollection =
new ArrayCollection([
{ id: "P1", name: "Porto", type: "team", children: [
{ id: "R1", name: "Dr Silva", location: "Bloco 1", type:
"member" },
{ id: "R2", name: "Dra Neto", location: "Gabinete", type:
"member"
{ id: "P2", name: "Braga", type: "team", children: [
{ id: "R3", name: "Dr Santos", location: "Bloco 2", type:
"member" },
{ id: "R4", name: "Dra Sonia", location: "Piso 1", type:
"member"
But I want to import it from a XML file like this:
<?xml version="1.0" encoding="utf-8"?>
<items>
<item id="P1" name="Porto" type="team">
<children id="R1" name="Dr Silva" location="Bloco 1"
type="member" />
<children id="R2" name="Dra Neto" location="Gabinete"
type="member" />
</item>
<item id="P2" name="Braga" type="team">
<children id="R3" name="Dr Santos" location="Bloco 2"
type="member" />
<children id="R4" name="Dra Sonia" location="Piso 1"
type="member" />
</item>
</items>
I already import the file, but can not translate the data
into a array collection.
private function initApp():void {
var httpService:HTTPService = new HTTPService();
httpService.url = "dataprovider.xml";
httpService.resultFormat = "e4x";
httpService.addEventListener(FaultEvent.FAULT,
onFaultHttpService);
httpService.addEventListener(ResultEvent.RESULT,
onResultHttpService);
httpService.send();
private function onFaultHttpService(e:FaultEvent):void
Alert.show("Error reading data file.");
private function onResultHttpService(e:ResultEvent):void
//Convert the xml data to a array collection
Thank you

Hello Peter, and thank you for your reply's.
My problem is that I'm receiving the data from the external
file and I don't know how to get the children in place... I mean, I
also have some data being received form a file that I can convert
into an array collection, but the thing is, that file doesn't have
children structure...
It's something like this:
<?xml version="1.0" encoding="utf-8"?>
<items>
<item id="T1" resourceId="R1" name="Cardiologia"
startTime="25-3-09 8:0:0" endTime="25-3-09 8:30:0" />
<item id="T2" resourceId="R2" name="Raio-X"
startTime="25-3-09 9:0:0" endTime="25-3-09 9:15:0" />
<item id="T3" resourceId="R3" name="Analises"
startTime="25-3-09 12:0:0" endTime="25-3-09 12:45:0" />
<item id="T4" resourceId="R4" name="Consulta"
startTime="26-3-09 8:0:0" endTime="26-3-09 9:0:0" />
</items>
And I solve it with this (don't know if is the best):
private function onResultHttpServiceTask(e:ResultEvent):void
var a:Array = xmlListToObjectArray(e.result.item);
tasks = new ArrayCollection(a);
protected function
xmlListToObjectArray(xmlList:XMLList):Array
var a:Array = new Array();
for each(var xml:XML in xmlList)
var attributes:XMLList = xml.attributes();
var o:Object = new Object();
for each (var attribute:XML in attributes)
var nodeName:String = attribute.name().toString();
var value:*;
value = attribute.toString();
o[nodeName] = value;
a.push(new ObjectProxy(o));
return a;
But when the children "enter in action" I don't know how to
bring them to the array...
This code you send it's preaty much the thing I need, but the
thing is that I don't know how to call the children with data as
e:ResultEvent...
If you can help a bit more, I would really appreciate...
Thank You
