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:
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
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>

Net::HTTP.post: sends POST request, returns response body.
Sends a PROPFIND request to the server; returns an instance of a subclass of Net::HTTPResponse.
The request is based on the Net::HTTP::Propfind object created from string path, string body, and initial headers hash initheader.
data = '{"userId": 1, "id": 1, "title": "delectus aut autem", "completed": false}' http = Net::HTTP.new(hostname) http.propfind('/todos/1', data)
Sends a TRACE request to the server; returns an instance of a subclass of Net::HTTPResponse.
The request is based on the Net::HTTP::Trace object created from string path and initial headers hash initheader.
http = Net::HTTP.new(hostname) http.trace('/todos/1')
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>
Returns a string representation of the request:
Net::HTTP::Post.new(uri).inspect # => "#<Net::HTTP::Post POST>"
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.
Returns the lines of the source code as an array of strings.
Binary search through the offsets to find the line number for the given byte offset.
Returns a string representation of this location.
Returns a new location that stretches from this location to the given other location. Raises an error if this location is not before the other location or if they don’t share the same source.
Join this location with the first occurrence of the string in the source that occurs after this location on the same line, and return the new location. This will raise an error if the string does not exist.
Returns a string representation of this comment.
Returns a string representation of this comment.
