I don't understand why got Access Violation error. :-(
Hello,
Also don't understand the reason and I can't reproduce this
error. Can you try to pass ubyte[] to f.write() explicitly
converting responseBody to array? Like
f.write(d.responseBody.data());
No no, not work. :-(
when i trying this:
File f = File(path_hash[web_url], "wb");
f.write( d.responseBody.data() );
f.close();
downloaded text file like a byte[] array:
[255, 216, 255, 225, 32, 246, 69, 120, 105, 102, 0, 0, 77, 77, 0,
42, 0, 0, 0, 8, 0, 7, 1 ... // this is a file that downloaded and
open notepad.exe
