Starts an HTTP session.

Without a block, returns self:

http = Net::HTTP.new(hostname)
# => #<Net::HTTP jsonplaceholder.typicode.com:80 open=false>
http.start
# => #<Net::HTTP jsonplaceholder.typicode.com:80 open=true>
http.started? # => true
http.finish

With a block, calls the block with self, finishes the session when the block exits, and returns the block’s value:

http.start do |http|
  http
end
# => #<Net::HTTP jsonplaceholder.typicode.com:80 open=false>
http.started? # => false

Finishes the HTTP session:

http = Net::HTTP.new(hostname)
http.start
http.started? # => true
http.finish   # => nil
http.started? # => false

Raises IOError if not in a session.

Sends a POST request to the server; returns an instance of a subclass of Net::HTTPResponse.

The request is based on the Net::HTTP::Post object created from string path, string data, and initial headers hash initheader.

With a block given, calls the block with the response body:

data = '{"userId": 1, "id": 1, "title": "delectus aut autem", "completed": false}'
http = Net::HTTP.new(hostname)
http.post('/todos', data) do |res|
  p res
end # => #<Net::HTTPCreated 201 Created readbody=true>

Output:

"{\n  \"{\\\"userId\\\": 1, \\\"id\\\": 1, \\\"title\\\": \\\"delectus aut autem\\\", \\\"completed\\\": false}\": \"\",\n  \"id\": 201\n}"

With no block given, simply returns the response object:

http.post('/todos', data) # => #<Net::HTTPCreated 201 Created readbody=true>

Sends the given request req to the server; forms the response into a Net::HTTPResponse object.

The given req must be an instance of a subclass of Net::HTTPRequest. Argument body should be given only if needed for the request.

With no block given, returns the response object:

http = Net::HTTP.new(hostname)

req = Net::HTTP::Get.new('/todos/1')
http.request(req)
# => #<Net::HTTPOK 200 OK readbody=true>

req = Net::HTTP::Post.new('/todos')
http.request(req, 'xyzzy')
# => #<Net::HTTPCreated 201 Created readbody=true>

With a block given, calls the block with the response and returns the response:

req = Net::HTTP::Get.new('/todos/1')
http.request(req) do |res|
  p res
end # => #<Net::HTTPOK 200 OK readbody=true>

Output:

#<Net::HTTPOK 200 OK readbody=false>

Posts data to a host; returns a Net::HTTPResponse object.

Argument url must be a URL; argument data must be a string:

_uri = uri.dup
_uri.path = '/posts'
data = '{"title": "foo", "body": "bar", "userId": 1}'
headers = {'content-type': 'application/json'}
res = Net::HTTP.post(_uri, data, headers) # => #<Net::HTTPCreated 201 Created readbody=true>
puts res.body

Output:

{
  "title": "foo",
  "body": "bar",
  "userId": 1,
  "id": 101
}

Creates a new Net::HTTP object, http, via Net::HTTP.new:

• For arguments address and port, see Net::HTTP.new.

• For proxy-defining arguments p_addr through p_pass, see Proxy Server.

• For argument opts, see below.

With no block given:

• Calls http.start with no block (see start), which opens a TCP connection and HTTP session.

• Returns http.

• The caller should call finish to close the session:

  http = Net::HTTP.start(hostname)
  http.started? # => true
  http.finish
  http.started? # => false
  

With a block given:

• Calls http.start with the block (see start), which:

  • Opens a TCP connection and HTTP session.

  • Calls the block, which may make any number of requests to the host.

  • Closes the HTTP session and TCP connection on block exit.

  • Returns the block’s value object.

• Returns object.

Example:

hostname = 'jsonplaceholder.typicode.com'
Net::HTTP.start(hostname) do |http|
  puts http.get('/todos/1').body
  puts http.get('/todos/2').body
end

Output:

{
  "userId": 1,
  "id": 1,
  "title": "delectus aut autem",
  "completed": false
}
{
  "userId": 1,
  "id": 2,
  "title": "quis ut nam facilis et officia qui",
  "completed": false
}

If the last argument given is a hash, it is the opts hash, where each key is a method or accessor to be called, and its value is the value to be set.

The keys may include:

• ca_file

• ca_path

• cert

• cert_store

• ciphers

• close_on_empty_response

• ipaddr (calls ipaddr=)

• keep_alive_timeout

• key

• open_timeout

• read_timeout

• ssl_timeout

• ssl_version

• use_ssl (calls use_ssl=)

• verify_callback

• verify_depth

• verify_mode

• write_timeout

Note: If port is nil and opts[:use_ssl] is a truthy value, the value passed to new is Net::HTTP.https_default_port, not port.

Returns a string representation of self:

Net::HTTP.new(hostname).inspect
# => "#<Net::HTTP jsonplaceholder.typicode.com:80 open=false>"

Returns true if the HTTP session has been started:

http = Net::HTTP.new(hostname)
http.started? # => false
http.start
http.started? # => true
http.finish # => nil
http.started? # => false

Net::HTTP.start(hostname) do |http|
  http.started?
end # => true
http.started? # => false

http.started? # => true
http.finish

With a block, calls the block with self, finishes the session when the block exits, and returns the block’s value:

http.start do |http|
  http
end
# => #<Net::HTTP jsonplaceholder.typicode.com:80 open=false>
http.started? # => false

Description

Returns the authority for an HTTP uri, as defined in www.rfc-editor.org/rfc/rfc3986#section-3.2.

Example:

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"
URI::HTTP.build(host: 'www.example.com', port: 80, path: '/foo/bar').authority #=> "www.example.com"

This is used as a predicate, and ought to be called first.

Mirrors the C extension’s StringQuery::constant? method.

Whether or not this string is a valid constant name.

Returns the value of the node as an IntegerNode or a FloatNode. This method is deprecated in favor of value or numerator/#denominator.
