See RFC 2616 section 9.3 for further details. If the files has not been modified since the time in the header a Not Modified response will be returned. The following example performs a conditional GET using the If-Modified-Since header. Other requests that can contain a body such as PUT can be created in the same way using the corresponding request class ( Net::HTTP::Put). You can call a HTTPClient instance from several threads without synchronization after setting up an instance.

HTTPClient instance is designed to be MT-safe. You can call a HTTPClient instance from several threads without synchronization after setting up an instance. The HTTPClient class provides several methods for accessing Web resources via HTTP. To send multipart/form-data use Net::HTTPHeader#set_form: req = Net :: HTTP :: Post. :main:HTTPClient The HTTPClient class provides several methods for accessing Web resources via HTTP. request( req)Įnd case res when Net :: HTTPSuccess, Net :: HTTPRedirection # OK else res.

The request types Net::HTTP supports are listed below in the section “HTTP Request Classes”.įor all the Net::HTTP request objects and shortcut request methods you may supply either a String for the request path or a URI from which Net::HTTP will extract the request path. If you wish to re-use a connection across multiple HTTP requests without automatically closing it you can use ::new and then call start and finish manually. The connection will remain open for multiple requests in the block if the server indicates it supports persistent connections. Net::HTTP::start immediately creates a connection to an HTTP server which is kept open for the duration of the block. request request # Net::HTTPResponse object end port) do | http | request = Net :: HTTP :: Get.
RUBY HTTP CLIENT CODE
The following example code can be used as the basis of an HTTP user-agent which can perform a variety of request types using persistent connections. body POST with Multiple Values ¶ ↑ uri = URI( '') get( uri) # => String GET with Dynamic Parameters ¶ ↑ uri = URI( '') get( '', '/index.html') # => String GET by URI ¶ ↑ uri = URI( '') They are not recommended if you are performing many HTTP requests. The Net::HTTP methods in the following section do not persist connections. This will also require 'uri' so you don't need to require it separately. Simple Examples ¶ ↑Īll examples assume you have loaded Net::HTTP with: require 'net/http' If you are only performing a few GET requests you should try OpenURI. URI::HTTP#host, URI::HTTP#port and URI::HTTP#request_uri are designed to work with Net::HTTP. For more details about HTTP see ( Net::HTTP is designed to work closely with URI.
