Returns a suggested filename.


Returns a suggested filename.
The method tries to create a filename using the following, in order:

  • A filename specified using the content disposition header.
  • The last path component of the URL.
  • The host of the URL.

If the host of URL can't be converted to a valid filename, the filename "unknown” is used.

In most cases, this method appends the proper file extension based on the MIME type. This method will always return a valid filename regardless of whether or not the resource is saved to disk.
