build(args) click to toggle source

Synopsis

See new

Description

Creates a new URI::Generic instance from components of URI::Generic with check. Components are: scheme, userinfo, host, port, registry, path, opaque, query and fragment. You can provide arguments either by an Array or a Hash. See new for hash keys to use or for order of array items.

Description

At first, tries to create a new URI::Generic instance using ::build. But, if exception URI::InvalidComponentError is raised, then it URI::Escape#escape all URI components and tries again.
