# The syntax of HTTP URIs is defined in RFC1738 section 3.3.
|
|
#
|
|
# Note that the Ruby URI library allows HTTP URLs containing usernames and
|
|
# passwords. This is not legal as per the RFC, but used to be
|
|
# supported in Internet Explorer 5 and 6, before the MS04-004 security
|
|
# update. See <URL:http://support.microsoft.com/kb/834489>.

#
|
|
# == Description
|
|
#
|
|
# Creates a new URI::HTTP object from components, with syntax checking.
|
|
#
|
|
# The components accepted are userinfo, host, port, path, query, and
|
|
# fragment.
|
|
#
|
|
# The components should be provided either as an Array, or as a Hash
|
|
# with keys formed by preceding the component names with a colon.
|
|
#
|
|
# If an Array is used, the components must be passed in the
|
|
# order <code>[userinfo, host, port, path, query, fragment]</code>.
|
|
#
|
|
# Example:
|
|
#
|
|
# uri = URI::HTTP.build(host: 'www.example.com', path: '/foo/bar')
|
|
#
|
|
# uri = URI::HTTP.build([nil, "www.example.com", nil, "/path",
|
|
# "query", 'fragment'])
|
|
#
|
|
# Currently, if passed userinfo components this method generates
|
|
# invalid HTTP URIs as per RFC 1738.

|
|
# == Description
|
|
#
|
|
# Returns the full path for an HTTP request, as required by Net::HTTP::Get.
|
|
#
|
|
# If the URI contains a query, the full path is URI#path + '?' + URI#query.
|
|
# Otherwise, the path is simply URI#path.
|
|
#
|
|
# Example:
|
|
#
|
|
# uri = URI::HTTP.build(path: '/foo/bar', query: 'test=true')
|
|
# uri.request_uri # => "/foo/bar?test=true"

# URI::HTTP.build(host: 'www.example.com', path: '/foo/bar').authority #=> "www.example.com"

|
# URI::HTTP.build(host: 'www.example.com', port: 8000, path: '/foo/bar').authority #=> "www.example.com:8000"
