Method: Addressable::URI.heuristic_parse

Defined in:
lib/vendor/addressable/lib/addressable/uri.rb

.heuristic_parse(uri, hints = {}) ⇒ Addressable::URI

Converts an input to a URI. The input does not have to be a valid URI — the method will use heuristics to guess what URI was intended. This is not standards-compliant, merely user-friendly.

No parsing is performed if the object is already an Addressable::URI. Defaults to {:scheme => "http"}.

Parameters:

Returns:
