A couple things here, I first talked about how to send an image and variables to the server (at the same time) on this post, but it felt a bit weird, the file had no name to retrieve it and the variables were sent as GET. Now while working a with a new colleague, he showed me this code that for him was nothing but for me was amazing. It is a little library called UploadPostHelper made by Jonathan Marston back in 2007 (2007! why didn’t someone talk to me about this library before!!!).
Anyway here is a little code snippet showing how to use it:
var jpegEncoder:JPGEncoder = new JPGEncoder(85); //using the JPGEncoder from as3corelib var jpegBytes:ByteArray = jpegEncoder.encode(myPicture.bitmapData); //encoding a Bitmap into a ByteArray var urlRequest : URLRequest = new URLRequest(); urlRequest.url = "THE URL OF YOUR SERVER SIDE SCRIPT"; urlRequest.contentType = 'multipart/form-data; boundary=' + UploadPostHelper.getBoundary(); urlRequest.method = URLRequestMethod.POST; //now create an object with the variables you want to send as POST var postVariables:Object = {variable1Name:variable1Data, variable21Name:variable2Data, variable3Name:variable3Data} urlRequest.data = UploadPostHelper.getPostData( 'image.jpg', jpegBytes,"filedata", postVariables); //here is where the magic happens, filedata will be the name to retrieve the file urlRequest.requestHeaders.push( new URLRequestHeader( 'Cache-Control', 'no-cache' ) ); //from here it is just a normal URLLoader _pictureUploader = new URLLoader(); _pictureUploader.dataFormat = URLLoaderDataFormat.BINARY; _pictureUploader.addEventListener( Event.COMPLETE, _onUploadComplete, false, 0, true ); _pictureUploader.load( urlRequest ); |
How easy and beautiful is that?
So can get the code for the UploadPostHelper at the bottom of this post or I have made a zip file with the .as file here.
Dude, 2007!
