Im trying to load a php file from my server, loading the PHP's URL directly gives me instant results however loading it using as3 URLLoader takes around 15 seconds. I have no idea why nor what im doing wrong... any ideas?
this is how I'm coding it
// Build the varSend variable
varSend = new URLRequest(prefix + "php/myphpPage.php"); varSend.method = URLRequestMethod.POST;
varSend.data = variables;
varLoader = new URLLoader;
varLoader.dataFormat = URLLoaderDataFormat.TEXT;
varLoader.addEventListener(Event.COMPLETE, loadInitialInfo);
varLoader.addEventListener(IOErrorEvent.IO_ERROR,onIOError);
var0 = var0;
variables.sendRequest = "AAA";
// Send the data to the php file
varLoader.load(varSend);
thanks a lot

I am trying to write into the file and everything was working fine upto the time i used File.desktopDirectory but after updating it with File.applicationDirectory lots of places i am getting security issue.
So overcome this issue i tried this code
File file = File.applicationDirectory.resolvePath("urlsList.properties");
var writeStream:FileStream = new FileStream();
var pathToFile:String = file.nativePath;
var destination:File = new File (pathToFile);
writeStream.open(destination, FileMode.WRITE);
file.moveTo (destination, true);
writeStream.close();
Now its throwing error at file.moveTo (destination, true);
SecurityError: fileWriteResource at flash.filesystem::File/moveTo()

Taking screenshot functionality was working in my application but now it is not working. The code I am using for taking screen shot in flex is as below:
I am using flex 3.5 SDK
private function captureScreenShot():void
{
var jpgSource:BitmapData = new BitmapData (siteDisplayContainer.width, siteDisplayContainer.height); // siteDisplayContainer is the <mx:VBox> flex container
jpgSource.draw(siteDisplayContainer);
var jpgEncoder:JPGEncoder = new JPGEncoder(85);
var jpgStream:ByteArray = jpgEncoder.encode(jpgSource);
var myDate:Date = new Date();
var unixTime:Number = Math.round(myDate.getTime()/1000);
var reqURL:String = parentApplication.imageDownloadScriptURL+unixTime+".jpg"; // imageDownloadScriptURL is the php file absolute path
var header:URLRequestHeader = new URLRequestHeader("Content-type", "application/octet-stream");
var jpgURLRequest:URLRequest = new URLRequest(reqURL);
jpgURLRequest.requestHeaders.push(header);
jpgURLRequest.method = URLRequestMethod.POST;
jpgURLRequest.data = jpgStream;
navigateToURL(jpgURLRequest, "_blank");
}
PHP file code for downloading flex screen shot:
<?php
if (isset($GLOBALS["HTTP_RAW_POST_DATA"]))
{
// get bytearray
$jpg = $GLOBALS["HTTP_RAW_POST_DATA"];
// add headers for download dialog-box
header('Content-Type: image/jpeg');
header("Content-Disposition: attachment; filename=".$_GET['name']);
echo $jpg;
echo '<script TYPE="text/javascript">window.close();</script>';
}
?>
Since the data is binary, I don't know how I can debug this code. I do not know where exactly is the code failing. There cannot be any major error since this exact code was working till about 6 months back.
How do I debug this code? What can be the reason for the code not working?
If it was working six months ago, have you checked your server settings for changes in the PHP version or security?
For testing the PHP, can you pass a binary into you it to verify that portion is working? For the flex side, I would setup the debugging version of flash player and then setup breakpoints and trace statements and just go through it and see if the flex debugging perspective and flash player give you any good debugging data to work with on narrowing down the culprit.
I have to build a banner where people fill a form with their name and email send when they click, we send the data in order to send them back a brochure instantly.
I am not a dev, so it is a little bit confusing for me and I hope my explanations will be clear enough.
Apparently, the website only accept POST request but we cannot send like that from the banner due to crossdomain issue. So the request has to be send as a GET.
We found this website which does the conversion:
http://get-to-post.nickj.org/
for the purpose of the test, everything is hardcoded. When we test, this url:
http://get-to-post.nickj.org/?http://www.vikingrivercruises.co.uk/Forms/SaveRequestBrochures?InquiryReason[0]=2351&InquiryMessage[0]=UK+River+Brochure+Download&InquiryType[0]=Brochure-d&InquiryReason[1]=1450&InquiryMessage[1]=UK+Brochure+Requests+%28from+web%29&InquiryType[1]=Brochure&BrochureCode=UKBR15&SelectedBrochuresDeliverability=UKBR15+mail-yes+ebrochure-yes&selectedBrochures=UKBR15&Title=Mr.&FirstName=Andrew&LastName=Davies&EmailAddress=nicom21a%40gmail.com&PhoneNumberString=098921313132312&Country=United+Kingdom&OtherCountry=&Address1=&Address2=&Address3=&City=&State=&OtherState=&Zip=&EmailMeSpecialOffers=true&FriendTitle=&FriendFirstName=&FriendLastName=&FriendEmailAddress=&RedirectUrl=http%3A%2F%2Fwww.vikingrivercruises.co.uk%2Fbrochures%2Frivers-brochure-thank-you.html
and copy past it in the browser, it works perfectly and we receive a brochure instantly, but when I try to replicate it from the banner it doesn't work.
Here is my code, many thanks
var requestVars:URLVariables = new URLVariables();
requestVars.link = 'InquiryReason[0]=2351&InquiryMessage[0]=UK+River+Brochure+Download&InquiryType[0]=Brochure-d&InquiryReason[1]=1450&InquiryMessage[1]=UK+Brochure+Requests+%28from+web%29&InquiryType[1]=Brochure&BrochureCode=UKBR15&SelectedBrochuresDeliverability=UKBR15+mail-yes+ebrochure-yes&selectedBrochures=UKBR15&Title=Mr.&FirstName=Andrew&LastName=Davies&EmailAddress=nicom21a%40gmail.com&PhoneNumberString=098921313132312&Country=United+Kingdom&OtherCountry=&Address1=&Address2=&Address3=&City=&State=&OtherState=&Zip=&EmailMeSpecialOffers=true&FriendTitle=&FriendFirstName=&FriendLastName=&FriendEmailAddress=&RedirectUrl=http%3A%2F%2Fwww.vikingrivercruises.co.uk%2Fbrochures%2Frivers-brochure-thank-you.html'
var request:URLRequest = new URLRequest();
request.url = 'http://get-to-post.nickj.org/?http://www.vikingrivercruises.co.uk/Forms/SaveRequestBrochures';
request.method = URLRequestMethod.GET;
request.data = requestVars;
for (var prop:String in requestVars) {
trace("Sent " + prop + " as: " + requestVars[prop]);
}
var loader:URLLoader = new URLLoader();
loader.dataFormat = URLLoaderDataFormat.TEXT;
loader.addEventListener(Event.COMPLETE, loaderCompleteHandler);
loader.addEventListener(HTTPStatusEvent.HTTP_STATUS, httpStatusHandler);
loader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler);
loader.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);
I also tried like that
request.url = 'http://get-to-post.nickj.org/?http://www.vikingrivercruises.co.uk/Forms/SaveRequestBrochures?';
I think there are many points in your case that should be clarified :
If you want send a URL request to a server, but ignores any response, and I think this is your case because you can't get response, It's better to use sendToURL instead of URLLoader.load().
If you test your swf on line, you will get a security error because the used site(http://get-to-post.nickj.org/) doesn't have a crossdomain.xml file to get authorization to execute the URL : http://get-to-post.nickj.org/?http://www.example.com/?param=value.
Even when you execute your sendToURL successfully, you have another problem because the site that you have mentioned, which convert GET request to a POST one, will not do the job because it's creating a page with a POST form with your data and submitting it when the page is loaded which is never fired with flash.
So, I think it's better to see the crossdomain problem with your target site (vikingrivercruises) to give you authorization to send POST data. And if It's always impossible, try to set another URL (site) that get your GET data and send it via curl, for example, to your destination.
How can I save the modified data to the same xml file after loading from that external xml file in ActionScript3.
Is there exist any function or method or any way to save the modified data again in the same file from which it was loaded.
import flash.net.URLRequest;
var myXML:XML = new XML();
var XML_URL:String = "sample.xml";
var myXMLURL:URLRequest = new URLRequest(XML_URL);
var myLoader:URLLoader = new URLLoader(myXMLURL);
myLoader.addEventListener("complete", xmlLoaded);
function xmlLoaded(event:Event):void
{
myXML = XML(myLoader.data);
trace("Data loaded.");
trace(myXML); //showing output of just loaded xml file.
//process of adding new child node or property.
var newnode:XML = new XML();
newnode =
<student >
<sname srno="2">mm</sname>
<father tax="no">
<fname>Ratan</fname>
<focc>business man</focc>
<mobno>9928946899</mobno>
</father>
</student>;
myXML = myXML.appendChild(newnode);
trace(myXML); //showing o/p after being the child-node appended.
}
where the sample.xml file located in the same working path, contains only the following data.-
<data>
<student srno="1" class="5" rollno="1">
<sname>Rohan Jain</sname>
<father tax="yes">
<fname>Ronak Jain</fname>
<focc>teacher</focc>
<mobno>9928946899</mobno>
</father>
</student>
</data>
If you're building a browser based application; nothing you can do on the client will save the file to a specific name and location. You'll have to send your updated doc to the server for saving. It is easy to write a service to do this in most server side languages I have dealt with.
If you want to save the file to the client machine; you can do so using FileReference.save(). However, this requires user input and there is no way to guarantee what the user will name the file or where they'll put it.
I want a user to press an excel button and get prompted to download an excel file. I normally do it like this:
var dest:String = excelEndpoint;
var request:URLRequest = new URLRequest();
request.url = dest;
fr.download( request,'Locates.xls' );
fr.addEventListener(HTTPStatusEvent.HTTP_STATUS, handleStatus);
fr.addEventListener(IOErrorEvent.IO_ERROR, handleErr);
However, now I need to pass an object to the servlet. Seeing that you can't do that with URLRequest I tried using HTTPService:
var service:HTTPService = new HTTPService();
service.url = excelEndpoint;
service.method = "POST";
service.showBusyCursor = true;
service.addEventListener("result", httpResult);
service.addEventListener("fault", httpFault);
service.send( myObject);
Now I can get my data (myObject) to the servlet successfully, but I don't get prompted for a download.
How can I do that? Is it even possible with HTTPService?
Thanks for any helpful tips.
I don't think there is anything you can do w/ a remote request from the Flash Player to prompt the user to download something. The way I have done this in the past is two fold:
Remote request pings server that generates the excel file and saves it to a temporary directory. The request returns a URL to the Flex app as the result of the call.
When Flex app gets the result--a URL--it creates a URL request and pops it open in a new window, prompting the user to download the generated excel sheet.
I don't see a way to do this in one shot; because the return value from the Flex HTTPService call goes to the Flash Player, not the browser.
SOLVED:
I wanted to accomplish this with 1 remote call and the way I found to do this while passing an object that contained collections is this:
var uv:URLVariables = new URLVariables();
uv.typesColl = myObj.types.toString();
uv.partiesColl = myObj.parties.toString();
uv.statuses = myObj.statuses.toString();
Basically, create a property on the URLVariables object for each collection and then set all collections toString();
Hope that helps someone.
