Zlib::GzipWriter

Zlib::GzipWriter is a class for writing gzipped files. GzipWriter should be used with an instance of IO, or IO-like, object.

Following two example generate the same result.

Zlib::GzipWriter.open('hoge.gz') do |gz|
  gz.write 'jugemu jugemu gokou no surikire...'
end

File.open('hoge.gz', 'w') do |f|
  gz = Zlib::GzipWriter.new(f)
  gz.write 'jugemu jugemu gokou no surikire...'
  gz.close
end

To make like gzip(1) does, run following:

orig = 'hoge.txt'
Zlib::GzipWriter.open('hoge.gz') do |gz|
  gz.mtime = File.mtime(orig)
  gz.orig_name = orig
  gz.write IO.binread(orig)
end

NOTE: Due to the limitation of Ruby’s finalizer, you must explicitly close GzipWriter objects by Zlib::GzipWriter#close etc. Otherwise, GzipWriter will be not able to write the gzip footer and will generate a broken gzip file.

File::Stat

Objects of class File::Stat encapsulate common status information for File objects. The information is recorded at the moment the File::Stat object is created; changes made to the file after that point will not be reflected. File::Stat objects are returned by IO#stat, File::stat, File#lstat, and File::lstat. Many of these methods return platform-specific values, and not all values are meaningful on all systems. See also Kernel#test.

IO::EWOULDBLOCKWaitReadable

exception to wait for reading by EWOULDBLOCK. see IO.select.

IO::EWOULDBLOCKWaitWritable

exception to wait for writing by EWOULDBLOCK. see IO.select.

DidYouMean::PlainFormatter

The DidYouMean::Formatter is the basic, default formatter for the gem. The formatter responds to the message_for method and it returns a human readable string.

IPAddr::InvalidAddressError

Raised when the provided IP address is an invalid address.

IPAddr::InvalidPrefixError

Raised when the address is an invalid length.

Net::HTTPRequest

This class is the base class for Net::HTTP request classes. The class should not be used directly; instead you should use its subclasses, listed below.

Creating a Request

An request object may be created with either a URI or a string hostname:

require 'net/http'
uri = URI('https://jsonplaceholder.typicode.com/')
req = Net::HTTP::Get.new(uri)          # => #<Net::HTTP::Get GET>
req = Net::HTTP::Get.new(uri.hostname) # => #<Net::HTTP::Get GET>

And with any of the subclasses:

req = Net::HTTP::Head.new(uri) # => #<Net::HTTP::Head HEAD>
req = Net::HTTP::Post.new(uri) # => #<Net::HTTP::Post POST>
req = Net::HTTP::Put.new(uri)  # => #<Net::HTTP::Put PUT>
# ...

The new instance is suitable for use as the argument to Net::HTTP#request.

Request Headers

A new request object has these header fields by default:

req.to_hash
# =>
{"accept-encoding"=>["gzip;q=1.0,deflate;q=0.6,identity;q=0.3"],
"accept"=>["*/*"],
"user-agent"=>["Ruby"],
"host"=>["jsonplaceholder.typicode.com"]}

See:

You can add headers or override default headers:

#   res = Net::HTTP::Get.new(uri, {'foo' => '0', 'bar' => '1'})

This class (and therefore its subclasses) also includes (indirectly) module Net::HTTPHeader, which gives access to its methods for setting headers.

Request Subclasses

Subclasses for HTTP requests:

Subclasses for WebDAV requests:

Net::HTTPInformation

Parent class for informational (1xx) HTTP response classes.

An informational response indicates that the request was received and understood.

RFC 9110.
Wikipedia.

Net::HTTPContinue

Response class for Continue responses (status code 100).

A Continue response indicates that the server has received the request headers.

References:

Net::HTTPEarlyHints

Response class for Early Hints responses (status code 103).

The Early Hints indicates that the server has received and is processing the request, and contains certain headers; the final response is not available yet.

References:

Net::HTTPMultiStatus

Response class for Multi-Status (WebDAV) responses (status code 207).

The Multi-Status (WebDAV) response indicates that the server has received the request, and that the message body can contain a number of separate response codes.
