Constructor Details

#initialize(scheme, userinfo, host, port, registry, path, opaque, query, fragment, parser = DEFAULT_PARSER, arg_check = false) ⇒ Generic

Args

scheme

Protocol scheme, i.e. ‘http’,‘ftp’,‘mailto’ and so on.

userinfo

User name and password, i.e. ‘sdmitry:bla’.

host

Server host name.

port

Server port.

Instance Attribute Details

#fragment ⇒ Object

Returns the fragment component of the Bundler::URI.

Bundler::URI("http://foo/bar/baz?search=FooBar#ponies").fragment #=> "ponies"



284
285
286
 
# File 'lib/bundler/vendor/uri/lib/uri/generic.rb', line 284

def fragment
  @fragment
end

#host ⇒ Object

Returns the host component of the Bundler::URI.

Bundler::URI("http://foo/bar/baz").host #=> "foo"

It returns nil if no host component exists.

Bundler::URI("mailto:[email protected]").host #=> nil

The component does not contain the port number.

Bundler::URI("http://foo:8080/bar/baz").host #=> "foo"

Since IPv6 addresses are wrapped with brackets in URIs, this method returns IPv6 addresses wrapped with brackets. This form is not appropriate to pass to socket methods such as TCPSocket.open. If unwrapped host names are required, use the #hostname method.

Bundler::URI("http://[::1]/bar/baz").host     #=> "[::1]"
Bundler::URI("http://[::1]/bar/baz").hostname #=> "::1"

# File 'lib/bundler/vendor/uri/lib/uri/generic.rb', line 244

def host
  @host
end

#opaque ⇒ Object

Returns the opaque part of the Bundler::URI.

Bundler::URI("mailto:[email protected]").opaque #=> "[email protected]"
Bundler::URI("http://foo/bar/baz").opaque     #=> nil

The portion of the path that does not make use of the slash ‘/’. The path typically refers to an absolute path or an opaque part. (See RFC2396 Section 3 and 5.2.)

#find_proxy(env = ENV) ⇒ Object

Returns a proxy Bundler::URI. The proxy Bundler::URI is obtained from environment variables such as http_proxy, ftp_proxy, no_proxy, etc. If there is no proper proxy, nil is returned.

If the optional parameter env is specified, it is used instead of ENV.

Note that capitalized variables (HTTP_PROXY, FTP_PROXY, NO_PROXY, etc.) are examined, too.

But http_proxy and HTTP_PROXY is treated specially under CGI environment. It’s because HTTP_PROXY may be set by Proxy: header. So HTTP_PROXY is not used. http_proxy is not used too if the variable is case insensitive. CGI_HTTP_PROXY can be used instead.

Raises:

#hostname ⇒ Object

Extract the host part of the Bundler::URI and unwrap brackets for IPv6 addresses.

This method is the same as Bundler::URI::Generic#host except brackets for IPv6 (and future IP) addresses are removed.

Sets the host part of the Bundler::URI as the argument with brackets for IPv6 addresses.

This method is the same as Bundler::URI::Generic#host= except the argument can be a bare IPv6 address.

uri = Bundler::URI("http://foo/bar")
uri.hostname = "::1"
uri.to_s  #=> "http://[::1]/bar"

If the argument seems to be an IPv6 address, it is wrapped with brackets.
