class HTTP::Client
Overview
An HTTP Client.
One-shot usage
Without a block, an HTTP::Client::Response
is returned and the response's body
is available as a String
by invoking HTTP::Client::Response#body
.
require "http/client"
response = HTTP::Client.get "http://www.example.com"
response.status_code # => 200
response.body.lines.first # => "<!doctype html>"
Parameters
Parameters can be added to any request with the HTTP::Params#encode
method, which
converts a Hash
or NamedTuple
to a URL encoded HTTP query.
require "http/client"
params = HTTP::Params.encode({"author" => "John Doe", "offset" => "20"}) # => author=John+Doe&offset=20
response = HTTP::Client.get "http://www.example.com?" + params
response.status_code # => 200
Streaming
With a block, an HTTP::Client::Response
body is returned and the response's body
is available as an IO
by invoking HTTP::Client::Response#body_io
.
require "http/client"
HTTP::Client.get("http://www.example.com") do |response|
response.status_code # => 200
response.body_io.gets # => "<!doctype html>"
end
Reusing a connection
Similar to the above cases, but creating an instance of an HTTP::Client
.
require "http/client"
client = HTTP::Client.new "www.example.com"
response = client.get "/"
response.status_code # => 200
response.body.lines.first # => "<!doctype html>"
client.close
Compression
If compress
isn't set to false
, and no Accept-Encoding
header is explicitly specified,
an HTTP::Client will add an "Accept-Encoding": "gzip, deflate"
header, and automatically decompress
the response body/body_io.
Encoding
If a response has a Content-Type
header with a charset, that charset is set as the encoding
of the returned IO (or used for creating a String for the body). Invalid bytes in the given encoding
are silently ignored when reading text content.

Constructor Detail
Creates a new HTTP client from a URI. Parses the host, port,
and tls configuration from the URI provided. Port defaults to
80 if not specified unless using the https protocol, which defaults
to port 443 and sets tls to true
.
require "http/client"
require "uri"
uri = URI.parse("https://secure.example.com")
client = HTTP::Client.new(uri)
client.tls? # => #<OpenSSL::SSL::Context::Client>
client.get("/")
This constructor will ignore any path or query segments in the URI as those will need to be passed to the client when a request is made.
If tls is given it will be used, if not a new TLS context will be created.
If tls is given and uri is a HTTP URI, ArgumentError
is raised.
In any case the active context can be accessed through #tls
.
This constructor will raise an exception if any scheme but HTTP or HTTPS is used.
Creates a new HTTP client from a URI, yields it to the block and closes the
client afterwards. Parses the host, port, and tls configuration from
the URI provided. Port defaults to 80 if not specified unless using the
https protocol, which defaults to port 443 and sets tls to true
.
require "http/client"
require "uri"
uri = URI.parse("https://secure.example.com")
HTTP::Client.new(uri) do |client|
client.tls? # => #<OpenSSL::SSL::Context::Client>
client.get("/")
end
This constructor will ignore any path or query segments in the URI as those will need to be passed to the client when a request is made.
If tls is given it will be used, if not a new TLS context will be created.
If tls is given and uri is a HTTP URI, ArgumentError
is raised.
In any case the active context can be accessed through #tls
.
This constructor will raise an exception if any scheme but HTTP or HTTPS is used.
Creates a new HTTP client, yields it to the block, and closes the client afterwards.
