Overview

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.

Constructor Details

#initialize(path, initheader = nil) ⇒ HTTPRequest

Creates an HTTP request object for path.

initheader are the default headers to use. Net::HTTP adds Accept-Encoding to enable compression of the response body unless Accept-Encoding or Range are supplied in initheader.
