Question

I’m writing a app with Flex/air,and i need a function that downloading files to the default dir without a pop-up window.i tried to use ftp instead of http but found it’s not supported by air.how can i solve this problem?

Answer 1

This should be possible in AIR. I don’t know if there’s a direct API approach, but you should be able to load the bytes into memory and then flush them into a file. In pseudo-pseudo-code using File and FileStream:

// get the bytes
var loader:URLLoader = new URLLoader();
loader.load("http://www.stackoverflow.com");
...
var bytes:ByteArray = loader.data;

// get the file in the correct location
var f:File = File.documentsDirectory.resolvePath("myfile.txt");

// write the file
var fs:FileStream = new FileStream(f, FileMode.WRITE);
fs.writeBytes(bytes);
fs.close();

There are a few examples out there to look at.

None of this is possible in Flash Player because of the security limits @viatropos suggests.
