Class Method Details

open(name, *rest, &block) (mod_func)

Allows the opening of various resources including URIs.

If the first argument responds to the 'open' method, 'open' is called on it with the rest of the arguments.

If the first argument is a string that begins with xxx://, it is parsed by URI.parse. If the parsed object responds to the 'open' method, 'open' is called on it with the rest of the arguments.

Otherwise, the original open is called.

OpenURI::OpenRead#open provides URI::HTTP#open, URI::HTTPS#open and URI::FTP#open, open.

We can accept URIs and strings that begin with http://, https:// and ftp://. In these cases, the opened file object is extended by ::OpenURI::Meta.
