HTTPService Component

Hello,
I am having problems with the following example using php/mysql:
http://livedocs.adobe.com/flex/3/html/help.html?content=data_access_2.html#196471
When uploaded on my server, it gives the dreaded "Security Error Accessing URL" message. I put the crossover.xml file in my root, but it doesn't work. I'm still learning, and haven't quite caught up with all the best practices in Flex. When I created my project, I said that it had no server type, and then to deploy on my web server, I am simply exporting as a release build and copying files. Is this poor practice and possibly the reason for this error? What is best practice? The php file works with a simple HTML site, so I know the code is working and the database is set up properly. Can someone please help me out?
Thanks,
Joe

Try adding --use-network=true to your compiler options.
In Flex Builder, in menubar:
Project - Properties
Flex Compiler
Additional compiler options
Often when we develop our apps this does not matter, but when posting online you need it set to true.

Multiple HTTP requests using single HTTPService component

Hi,
I am having one requirement, I need to use a single HTTPService component to send request to a same and single ASP.net multiple times.
How can I acheive that..? I know that I can acheive this by sending one request at a time and after the "result" event is called for the first request then sending the second request and so on...
But if I do so then it will be delayed response as I need to wait until the result handler for the previous request is called...
So how do I do this..?
Any help greatly appreciated....:)
Thanks in advance..
Thanks,
Bhasker Chari

yep, the setting works when set to 10. Seemed to not work when set to 20. Anyways, summary is "long polling" and Flex
or Flash are not good compatriates. So, you will need to work out your own mechanism on the server or client
side to limit the sockets used/wasted. Painful but true.

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="

<mx:HTTPService id="textService" url="

<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!!!

(HTTPService - result="" - to ArrayCollection) - a question for super expert ;)

Firstly look at my example then you will read the question:
Look at example below - I'm using HTTPService component to retrieve data from SQL database
(read_record.php is generating nice and tidy xml file with my data)


    <mx:HTTPService id="readTimed"
        url="http://www.pudelek.pl/SCRIPT/A/read_record.php"
        result="patient(event)">
    </mx:HTTPService>
Then 'result' is calling a function patient() which task is to assign 'event.result'
to ArrayCollection called 'A_patient_dp' (this ArrayCollection is a data provider
for a specific data grid)
private function patient(event:ResultEvent):void {
    trace("A - PATIENT - loaded...")
    trace(event.result.patient.patient)
    A_patient_dp = event.result.patient.patient
Everything looks great here, data grid shows all the data from xml file generated
by read_record.php
and now is my problem :
I don't want to display all the data, I want HTTPService to retrieve only particular data
which are described by variable {parametr} - this var is generated by my application
I've dond it this way:


    <mx:HTTPService id="readRequestA"
        url="http://www.pudelek.pl/SCRIPT/A/A_send_read_record.php"
            useProxy="false"
            method="POST">
        <mx:request xmlns="">
            <idstaff>{parametr}</idstaff>
        </mx:request>
    </mx:HTTPService>
I'm looking into source of 'A_send_read_record.php' in the internet browser and I see
exact data tree (filtered) which I need.
The problem here is : how to call function patient(event:ResultEvent) and give it
data from the event to be assigned to ArrayCollection - like in first example.
Thanks for all the ideas !!

Disable form while submitting data (via HTTPService)

And how can I let them know once the data submission has been
completed?
So far, i've been using Alert.show() for both submission +
notification of submission completion but it's a little weird b/c
the first alert is below the second alert... so the user has to
click twice to get back to the form. Not to mention the FIRST alert
window is still after data has been submitted...
Any recommendations?

Hi,
I think this is happening because the response from the
server is received before the user clicks OK on the Alert showing
that the data is being submitted.
I think of two solutions for this,
One is set the showBusyCursor property of the HTTPService
component to true. So that a busy cursor will be displayed to the
user when you call the send() method of the HTTPService, till the
response is back from the server.
Second is to have a custom component displaying message
asking the user to wait, which can be popped up using PopupManager
when the user clicks on submit and then remove it when the response
is back from the server.
Hope this helps.

HTTPService POST sends header and body separately

I'm having a performance issue with XML-RPC via the
HTTPService component. The HTTPService.send() sends the request in
two parts: first the headers, then the body. Evidently, the server
get the headers, times out, sends an ACK, and then HTTPService
sends the body, resulting in very poor performance. Here's the
timeline, from the client's view:
Time = 0.000000 - POST Partial Message Headers
Time = 0.108784 - ACK for POST Partial Message Headers
received (TCP ACK Packet)
Time = 0.108824 - POST Completion of Message Headers +
Message Body (contains XML-RPC method)
Time = 0.110257 - Response received (containing XML-RPC
methodResponse)
Time = 0.359815 - ACK for Response (TCP ACK Packet)
Yep, 108ms wasted waiting for an ACK for the headers!
The question is, is there any way to cause the headers and
body to be sent together? Otherwise, I'll have to look at using
Sockets...
Thanks, JohnB

Well, I solved my performance problem by using XMLSocket,
instead of HTTPService - a shame, since HTTPService is more
appropriate.
Question: how do I determine whether Adobe knows about this
issue, and whether they care?

Now i want to retreive all "Category" elements in the XML, i
tried using the below code it didn't work,
var temp:XML = XML(event.result);
var category:* = temp.elements("Category"); // to retrieve
Category Elements
but i don't see any elements in it. What am i doing wrong
please let me know.

Weird. It works for me. I did have to remove the namespace
from the XML. I assume there is a way to do this in

HTTPService Security Sandbox Violation

Hello there.
Using the HTTPService component to the URL that is seen
below,
I get the following message:
[SWF]
D:\AdobeFlexTraining\_workspace\AdobeODT\bin-debug\AdobeODT.swf -
1,042,346 bytes after decompression
*** Security Sandbox Violation ***
Connection to

I have a trial version of Flex Builder 3.
How can I run this request, nevertheless.
Thanks

Probably FB, being an IDE, allows you to act as if you were
on the network, so -use-network=true may be ignored (unless you
execute the SWF outside of FB).
The command line probably respects -use-network=true so for
testing set to false, and when putting the SWF on the network set
to true.

Getting the values from Servlet

Hi EveryOne,
I have done one thing using Flex,i have send the parmeters
from flex to servlet using HttpService and in the servlet i
captured them and used them.Now what i want is i have to capture
the values from servlet to flex .
Response content in servlet is set to text/xml,any one please
give me the idea how to do thsi or please send me some code to do
this.
{Sorry for my English} Thanks,
Namala.

Hi,
You have to handle the result event of the HTTPService
component. In the result handler you will have access to the
ResultEvent object which will contain the response from the server
in the "result" property. Please visit the URL below for more
details on how to handle result from the server.

Reg - How to remind previous view state?

Hi,
I have the following requirement:
In mobile application, the home view screen has a text input and button controls. Text input will contain a service URL (value provided at run time), on click of the button, the given URL (specified in text box) will be executed using HTTPService component. The resultant value will be bound to a List component. On select of the list item, next view (details view) will be launched with the selectedItem value. The details view has 'Back' button, on press of back button the home view will be launched. On launch of Home view from the details view i need to maintain the previous state (resultant value) as it is. How can i implement this?
Note: I don't want to allow user to give input and fire a service on each time return back from 'Details view'
I just tried and can able to pass and return the URL value using 'navigator.poppedViewReturnedObject' but it requires need to fire a HTTPservice again on launch of 'Home view' from 'Details view'. How i overcome this? or am i understood wrongly?
Can you help me with your knowledge and experince?
Thanks and Regards,
Manikandan

Hi Mani,
You can use persistence manager.
If I have understood you correct.These two links can help you achive what you want.

Flex, xml, and non-English characters

Hello! I have a Flex web app with AdvancedDataGrid. And I use httpService component to load some data to grid. The .xml file contains non-english characters in attributes (russian in my case) like this:
<?xml version="1.0" encoding="utf-8" ?>
   <Autoparts>
    <autopart DESCRIPTION="Барабан">
</Autoparts>
And when i run app, AdvancedDataGrid display it like "ÑÐŸÐ". How can i fix it? I try to change encoding="utf-8" with some another charsets, bun unsuccesfully. Thank you.

Try changing the xml structure by using CDATA instead of having the russian part as an attribute and see if that makes any difference.
What I meant is use something like this:
<?xml version="1.0" encoding="utf-8" ?>
   <Autoparts>
    <autopart>
       <description><![CDATA[Барабан]]></description>
</autopart>
</Autoparts>
instead of the current xml.

Sending attachments/binary data from flex to Restful APIs

Hi,
We have a requirement of sending the files (or binary data) from flex GUI to Restful services(backend APIs). We are using flex HTTPService component to invoke the rest apis. The Rest APIs are designed to accept the multipart/mixed data which can support the binary data as well.
Can any one help us understand, how can we send the multipart/mixed OR multipart/form-data from flex to backend using the HTTPService. Or is there a better way to send the mixed data from Flex GU to Restful APIs.
Request you to please respond to this at the earliest as this is very urgent.
Thanks and Regards,

How do I change below to make it work with https? I tried with AMFSecureChannel but that did not work. Appreciate any help... thanks!
<channel-definition id="my-amf-poll" class="mx.messaging.channels.AMFChannel">
    <endpoint

        <polling-interval-seconds>1</polling-interval-seconds>
    </properties>
</channel-definition>

Hi
I think you don't need to do all these things. With default setting create a HTTPService component and assign the required url to it. You can assign the resultFormat.Call the send() method. Optionally you can pass argument to it.
Hope this helps

[Unload SWF] appears in console and hangs app

Occasionally, "[Unload SWF] path:main-debug.swf" appears and
kills any HTTPService calls that are made.
The app behaves as such:
1. About 4 HTTPService calls are made at once, using
different HTTPService instances.
2. Occasionally, in the debug console a "[Unload SWF]..."
appears, showing the path to my app. Sometimes it appears once for
every webservice call that I make.
3. Each webservice that gets the "[Unload SWF]" will never
return and hangs forever.
Sometimes, I'll also see a "[SWF] path:main-debug.swf"
message in the console, at which point the webservices will hang
again. If I click "Cancel" in my app, then try it again, they will
sometimes magically work (and I don't get those [Unload SWF]
messages).
Any help would be greatly appreciated!
-Michael Whitaker:confused;

Unbelievable...
I think I may have found the problem and solution:
The way I was using the HTTPService component was through a
seperate class which itself contained the httpservice that I was
instantiating and calling on a per-need basis. The function I was
using to call my web service needs accepted two function pointers
(or Function types) which were called on a ResultEvent or a
FaultEvent (from the HTTPService). I was using lamba functions
(inline functions) in the method call. That is what seemed to be
the problem. As soon as I moved the lamba functions outside ,into
real functions, and just passed their reference through my method,
everything worked.
I've noticed several problems with lamba functions, all of
which are very unfortunate (because I would use them more, but they
are so buggy):
1. A lamba function sometimes has some weird scope. At times
calling "this.something" fails from within the lamba function as
'this' is null. Ex:
class Bob
public Bob()
this.addEventListener(Event.ENTER_FRAME,
function(e:Event):void { trace("this: " + this.toString()); },
false, 0, true);
(Note: this is 1% psudo code (uncompiled).) "this" will
sometimes be null (depending on where the lamba is used).
2. If, using the above code, you were to instantiate several
Bobs at a time, and add them to the displaylist, sometimes only ONE
of the instances will actually call their lamba function on
enterframe; the others won't. I'm not sure why this happens, but I
think multiple instances of the same class using a lamba function
tends to conflict in memory or something. (or in the special
lamba-scope).
3. At times, as per my problem in this thread, a lamba
function won't even be called. I've solved this by pulling out the
lamba functions and placing them in real functions, then just
passing the pointer across.
I guess the debugger sending [Unload SWF] and [SWF] messages
were just a coincidence (unless they somehow affect lamba
functions). I'm going to continue testing this to verify that the
problem has gone away. If it hasn't, I'll probably start a new
thread.
Thanks for your help mike_morearty!
