iOS, Andorid のアプリを配布するCGI

iOSのほうはiDEP取って inhouseってことで。

else:
  fx = open("/var/uso/jordan/%s"%f, 'rb')
  fx.seek(0, 2)
  bytes = fx.tell()
  fx.seek(0, 0)
  ctype = "text/plain; charset=UTF-8"
  if '.apk' in f:
    ctype = "application/vnd.android.package-archive"
  elif '.ipa' in f:

  print """Content-Type: %s

  while True:

    sys.stdout.write(data)
    if not data: break
  fx.close()

みたいな？

あいかわらず雑ですが。
