Flex HTTPservice and POST, Sending Files ?

Question

Hello,

I use a basic Post to send data to a Django server.

The data consists of a base64 encoded 640*380 PNG image dynamically created by the flex component.

<mx:HTTPService id="formSend" showBusyCursor="true" 
    useProxy="false" url="http://127.0.0.1/form/" 
    method="POST" result="formSentConfirmation(event)"    fault="formSendingFailed(event)"/>



private function sendForm(url:String, message:String, meteo:Number):void {
    formSend.url = url;
    var params:Object = { message: message, image_data: getEncodedImage() }; 
    snapButton.label = "sending ...";
    formSend.send(params);
}

On the server side i can see that the data is in the request.POST not in request.FILES. That means the image is not send as a File with multiencode HTTP.

1. Will i get into trouble on a real server ? since the limit is 200k for urlencoded POST var.

2. How to make HTTPservice send the data as a file?

3. Any other solutions?

Thanks

Answer 1

1. Probably, yes. It depends whether you impose a hard limit on the the file size and how the destination page handles the request.

2. I don't believe it's actually possible at the moment.

3. Read this. FileReference is the recommended way of uploading files.

Answer 2

FileRefrence does not work on HTTPS on mozila, any idea how to do other than that

Answer 3

Im actually on the same problem, Is there anyway to create a new FileRefence from a Data without using the .browse??? So we could use the .upload method ! ?

Answer 4

Found something interesting than we can dig on it. Use this:

var urlLoader:URLLoader = new URLLoader();
 urlLoader.dataFormat = URLLoaderDataFormat.BINARY;
 urlLoader.data = _img.data;
 urlLoader.addEventListener(Event.COMPLETE,LoadedComplete);

 var request:URLRequest = new URLRequest("www.url.com?toto=toto");
 request.method = URLRequestMethod.POST
 request.contentType = "multipart/form-data";
 request.data = _img.data;
 request.requestHeaders = new Array(new URLRequestHeader("toto", "toto"));

 urlLoader.load(request);

Well with that i get something in C# server side the request content length is not empty and i got toto in the params and in the header, one problem in files collection there are no files sent ... where are the sent bytes ???
