Yields each source URI
in the list.
Default fetcher instance. Use this instead of ::new
to reduce object allocation.
Enumerate every known spec. See ::dirs=
and ::add_spec
to set the list of specs.
v
Public setter for the scheme component v
(with validation).
See also URI::Generic.check_scheme
.
require 'uri' uri = URI.parse("http://my.example.com") uri.scheme = "https" uri.to_s #=> "https://my.example.com"
Returns true if URI
is hierarchical.
URI
has components listed in order of decreasing significance from left to right, see RFC3986 www.rfc-editor.org/rfc/rfc3986 1.2.3.
require 'uri' uri = URI.parse("http://my.example.com/") uri.hierarchical? #=> true uri = URI.parse("mailto:joe@example.com") uri.hierarchical? #=> false
Return value associated with key
.
If there is no value for key
and no block is given, returns ifnone
.
Otherwise, calls block passing in the given key
.
See ::DBM#fetch for more information.
Obtains a lock, runs the block, and releases the lock when the block completes. See the example under Thread::Mutex
.
Iterates over keys and values. Note that unlike other collections, each
without block isn’t supported.
Executes the block for every line in the stream where lines are separated by eol.

Reads a one-character string from the stream. Raises an EOFError
at end of file.
Generate a Checkbox Input element as a string.
The attributes of the element can be specified as three arguments, name
, value
, and checked
. checked
is a boolean value; if true, the CHECKED attribute will be included in the element.
Alternatively, the attributes can be specified as a hash.
checkbox("name") # = checkbox("NAME" => "name") checkbox("name", "value") # = checkbox("NAME" => "name", "VALUE" => "value") checkbox("name", "value", true) # = checkbox("NAME" => "name", "VALUE" => "value", "CHECKED" => true)
With a block, returns the string value for key
if it exists; otherwise returns the value of the block; ignores the default_val
; see Fields:
res = Net::HTTP.get_response(hostname, '/todos/1') # Field exists; block not called. res.fetch('Connection') do |value| fail 'Cannot happen' end # => "keep-alive" # Field does not exist; block called. res.fetch('Nosuch') do |value| value.downcase end # => "nosuch"
With no block, returns the string value for key
if it exists; otherwise, returns default_val
if it was given; otherwise raises an exception:
res.fetch('Connection', 'Foo') # => "keep-alive" res.fetch('Nosuch', 'Foo') # => "Foo" res.fetch('Nosuch') # Raises KeyError.
Returns true
if field 'Transfer-Encoding'
exists and has value 'chunked'
, false
otherwise; see Transfer-Encoding response header:
res = Net::HTTP.get_response(hostname, '/todos/1') res['Transfer-Encoding'] # => "chunked" res.chunked? # => true
returns a charset parameter in Content-Type field. It is downcased for canonicalization.
If charset parameter is not given but a block is given, the block is called and its result is returned. It can be used to guess charset.
If charset parameter and block is not given, nil is returned except text type. In that case, “utf-8” is returned as defined by RFC6838 4.2.1
