[flexcoders] HTTPService retrieves no data within itemrenderere

2012-10-04 Thread kaushal.shah123


I have an Horizontal list that is connected to patients
arraycollection.

I've created an Canvas Itemrenderer for the horizontal list that lists
the patient's medical information.

Within the itemrenderer, I am calling out to a PHP HTTPService call to
retrieve the visits for each patient.   However I am not getting any
data returned.

If I run the HTTPService in the main application, it works.







My main app code below:

mx:HorizontalList id=h_compare width=100% height=100%
dataProvider={myCompare} labelField=name
itemRenderer=comparerenderer columnWidth=500

rowHeight={hbox_compare.height} borderColor=haloBlue
scrollTipFunction=horizontalList_scrollTipFunc showScrollTips=true 
alternatingItemColors=[#FF, #EE] backgroundAlpha=.5
removedEffect={fadeOut}/







Itemrenderer code below  (Screenshot also attached).

[flexcoders] httpservice url - not use host

2012-05-03 Thread Sells, Fred

Since the Flex crossdomain policy would normally restrict you to the
server that launched Flex, is there any way to avoid specifying the
whole http://myserver.mydomain.com  prefix in the httpservice.url
parameter similar to the action in html forms?

 

I'm trying to make it easier to move my solution from one server to
another.

[flexcoders] HTTPService in Proxy with authentication.

2012-04-20 Thread Wemerson Couto Guimarães

Greetings!

I use HTTPServices to access our server, but in some clients the internet
access is by authenticated proxy. How do I set my HTTPService to access
using a specific port and proxy connections to exit?

The proxy / firewall uses port 3128. All browsers must be configured to use
that port and I need  to implement this in flex.

Another detail: When trying to access out, still have to inform login and
password!

[flexcoders] HttpService resultHandler in different Window

2012-02-13 Thread isa_loyer

I am working on an AIR application with 2 windows: One to create a new customer 
and another to display some information about the customer. On window 1, there 
is also a textfield to search for a customer by Id or name.

These are the steps to create a new customer:

with an add button on window 1, I open window 2.
on window 2, the user completes a form to create a new customer.
the information is saved in a MySQL Database over an HttpService.
The result handler method calls a public function on window 1:

result = new wWin1().resultSaveCustomer(event)
This part works well - the new customer Id is received.

In some cases, according customer data, I change the component color - this 
operation works well, if I load a customer after a using the search field, but 
if I search directly from the resultSaveCustomer function (after completion of 
step 3), a message appears:

Cannot access a property or method of a null object reference.

I don't understand why, because all the components in window 1, have an Id 
name! Or the property is a label with Id Name.

Thanks for helping me.

Re: [flexcoders] HTTPService post to return an image?

2011-11-03 Thread Rogerio Gonzalez

You can use base64 to encode your image on the server side, and then decode
in flex to display it.

 Is it possible to return an image object using HTTPService?

 The fault method executes when I attempt to do this:

 var http:HTTPService = new HTTPService();
 http.url = myScript.ashx;
 http.method = POST;
 http.resultFormat = object;

 Should URLLoader be used instead?

Hello 

You cant send raw binaries via a http api 
two things i suggest you may do

1) convert your binary data  to hexadecimal (hex) Xters at the server site  and 
send it across the web as hex data then reconvert your  hex data to binaries on 
the browser.

2) Save the image on a path on the server, obtain the url to the path of the 
image
    return the url with httpservice (as a string offcourse) and set as 
imagepath to your image control.  


All the best !

[flexcoders] HttpService error handling

2011-11-02 Thread Sells, Fred

I'm using Flex 4.1 with a django backend.  Django provides a really
useful HTML error traceback when it fails.  Currently I then have to
manually insert the offending url into the browser url to see the error
details when debugging.  That's a pain.   I would like to subclass
HttpService to provide a generic automatic solution, but I'm having
trouble.

 

My typical pattern is

Var parms:Object = new Object()

Parms.a=3

Parms.b=4

MyHttpService.url = http://yadda.yadda.yadda/root/function;

MyHttpService.send(parms)

 

When the faultHandler is called I would like to do something like this

navigateToURL( new URLRequest(
Configure.getServer()+'getpdf?id='+parms.id+resid=+parms.resid ) ); 

 

but I cannot find a way to get the parms back from the HttpService in
order to create the URLRequest string.  I've tried the
MyHttpService.request object but that appears to be empty.  It won't
expand in debugger view and a for loop does not iterate through it.

 

Can anyone offer a suggestion?

 

Thanks,

Fred.

[flexcoders] HttpService results inconsistent

2011-08-24 Thread Sells, Fred

If I have multiple records in the response I get an ArrayCollection
however if I have only 1 record I get an ObjectProxy.  I'm not sure if
specifying the resultFormat would resolve this and if so, which format
is appropriate.  I typically map the results to an ArrayCollection which
is the dataProvider for a datagrid.

 

Perhaps I should just map the datagrid .dataProvider to the
HttpService.lastResult...

 

Any suggestions or experience with this.  My code is below:

 

 

mx:HTTPService id=QueryService
result=QueryService_resultHandler(event) /

...

protected function QueryService_resultHandler(event:ResultEvent):void
{

try { GridDataArray = event.result.resultset.record;

}catch (e:*) {  GridDataArray = new ArrayCollection();  }

mydatagrid.dataProvider = GridDataArray;

}__,_

 

-- results with std xml header removed
-

resultset

record order__therapy=OT name=Landers, Ivee
time__id=3  time__label=08:00   id=3 order__resident__payor=3/

Re: [flexcoders] HTTPService DELETE/PUT automatically got changed to GET??

2011-08-20 Thread Peter Coppens

Fwiw...

As far as I know that is indeed still the case. The doc
(http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/mx/rpc/http/mxml/HTTPService.html)
says

You use the mx:HTTPService tag to represent an HTTPService object in an MXML
file. When you call the HTTPService object's send() method, it makes an HTTP
request to the specified URL, and an HTTP response is returned. Optionally, you
can pass parameters to the specified URL. When you do not go through the
server-based proxy service, you can use only HTTP GET or POST methods. However,
when you set the useProxy property to true and you use the server-based proxy
service, you can also use the HTTP HEAD, OPTIONS, TRACE, and DELETE methods.

In general, unless you can get somewhere some server/proxy control, I have
found Flex not very useful to talk to a REST like service. Some people have
reported success by using http://code.google.com/p/as3httpclientlib/ iso the
Flex provided stuff. Personally I have not tried that. As far as I remember it
gets tricky as you cannot typically reuse browser managed http resources
(cookies, cache, ...).

As it might be of interest to you as well.besides the limited HTTP verb
support I have lost numerous hours getting HTTP headers across. That is also a
non trivial endeavor.

What eventually worked out best in my case is to just bite the bullet , shove a
proxy in between, and use GET and POST to communicate tunneled real HTTP
requests, that are then transformed and forwarded. That is still not perfect if
you care about caching and have a need for custom headers, but at least most of
it is working.

I have always found it a bit ironic that a platform that started it's life as a
toolset to develop Rich Internet Applications has such limited support for
the internet standard as old as HTTP.

Anyway, hth,

Peter

Hi all,

I just would like to get a confirmation.
Right now, I have to use 3rd party REST APIs in our Flex app.
A bunch of the REST APIs are using DELETE and PUT method.

As the title said, they got changed automatically to GET.
And from what I gather from this forum somebody said this in 2008:
It's a limitation of the browser plugin API unfortunately.
