How to download flash files embedded using SWFObject

downloadflashswfobject

A site I use displays a flash file, which is embedded dynamically using SWFObject. I want to download the flash file locally, so I can run it when I don't have access to the net. However, when I try to open the url to the swf file, it demands an 'id' parameter that is normally passed by the SWFObject Javascript.

Specifically, the source of the page contains:

swfobject.embedSWF("/bin/loader.swf", "main", "100%", "100%", "9", false, flashvars, params, attributes);

And the flashvars have the following definiton:

var flashvars = {
        file_id: "imilc2lxnfft",
        app: "main-502.swf",
        show_play_button: "false",
        autoplay: ""

When I try to access site.com/bin/loader.swf, it says it requires a file_id parameter.

How do I pass the parameter and download the file to my desktop?

Save locally (with a D/L manager):

http://example.com/bin/loader.swf
http://example.com/main-502.swf

And create a local HTML file with the SWFObject JS code, including the flashvars and a <div> in your page with the right id (id="name" in this case).

It's also possible you don't need the loader, and the 2nd swf file will work standalone.

Java – How to download and save a file from the Internet using Java

Give Java NIO a try:

URL website = new URL("http://www.website.com/information.asp");
ReadableByteChannel rbc = Channels.newChannel(website.openStream());
FileOutputStream fos = new FileOutputStream("information.html");
fos.getChannel().transferFrom(rbc, 0, Long.MAX_VALUE);

Using transferFrom() is potentially much more efficient than a simple loop that reads from the source channel and writes to this channel. Many operating systems can transfer bytes directly from the source channel into the filesystem cache without actually copying them.

Check more about it here.

Note: The third parameter in transferFrom is the maximum number of bytes to transfer. Integer.MAX_VALUE will transfer at most 2^31 bytes, Long.MAX_VALUE will allow at most 2^63 bytes (larger than any file in existence).
