see: + # + # - Gem::Net::HTTPRequest. + # - Gem::Net::HTTPResponse. + # + # == Following Redirection + # + # Each returned response is an instance of a subclass of Gem::Net::HTTPResponse. + # See the {response class hierarchy}[rdoc-ref:Gem::Net::HTTPResponse@Response+Subclasses]. + # + # In particular, class Gem::Net::HTTPRedirection is the parent + # of all redirection classes. + # This allows you to craft a case statement to handle redirections properly: + # + # def fetch(uri, limit = 10) + # # You should choose a better exception. + # raise ArgumentError, 'Too many HTTP redirects' if limit == 0 + # + # res = Gem::Net::HTTP.get_response(Gem::URI(uri)) + # case res + # when Gem::Net::HTTPSuccess # Any success class. + # res + # when Gem::Net::HTTPRedirection # Any redirection class. + # location = res['Location'] + # warn "Redirected to #{location}" + # fetch(location, limit - 1) + # else # Any other class. + # res.value + # end + # end + # + # fetch(uri) + # + # == Basic Authentication + # + # Basic authentication is performed according to + # {RFC2617}[http://www.ietf.org/rfc/rfc2617.txt]: + # + # req = Gem::Net::HTTP::Get.new(uri) + # req.basic_auth('user', 'pass') + # res = Gem::Net::HTTP.start(hostname) do |http| + # http.request(req) + # end + # + # == Streaming Response Bodies + # + # By default \Gem::Net::HTTP reads an entire response into memory.

Gem::Net::HTTP.get(uri) + # + # == Proxy Server + # + # An \HTTP object can have + # a {proxy server}[https://en.wikipedia.org/wiki/Proxy_server]. + # + # You can create an \HTTP object with a proxy server + # using method Gem::Net::HTTP.new or method Gem::Net::HTTP.start. + # + # The proxy may be defined either by argument +p_addr+ + # or by environment variable <tt>'http_proxy'</tt>. + # + # === Proxy Using Argument +p_addr+ as a \String + # + # When argument +p_addr+ is a string hostname, + # the returned +http+ has the given host as its proxy: + # + # http = Gem::Net::HTTP.new(hostname, nil, 'proxy.example') + # http.proxy? # => true + # http.proxy_from_env? # => false + # http.proxy_address # => "proxy.example" + # # These use default values. + # http.proxy_port # => 80 + # http.proxy_user # => nil + # http.proxy_pass # => nil + # + #

+ # === Proxy Using '<tt>ENV['http_proxy']</tt>' + # + # When environment variable <tt>'http_proxy'</tt> + # is set to a \Gem::URI string, + # the returned +http+ will have the server at that URI as its proxy; + # note that the \Gem::URI string must have a protocol + # such as <tt>'http'</tt> or <tt>'https'</tt>: + # + # ENV['http_proxy'] = 'http://example.com' + # http = Gem::Net::HTTP.new(hostname) + # http.proxy? #

+ # With method Gem::Net::HTTP.new (but not Gem::Net::HTTP.start), + # you can use argument +p_no_proxy+ to filter proxies: + # + # - Reject a certain address: + # + # http = Gem::Net::HTTP.new('example.com', nil, 'proxy.example', 8000, 'pname', 'ppass', 'proxy.example') + #

+ # http = Gem::Net::HTTP.new('example.com', nil, 'proxy.example', 8000, 'pname', 'ppass', 'my.proxy,proxy.example:8000') + # http.proxy_address # => nil + # + # http = Gem::Net::HTTP.new('example.com', nil, 'my.proxy', 8000, 'pname', 'ppass', 'my.proxy,proxy.example:8000') + # http.proxy_address # => nil + # + # == Compression and Decompression + # + # \Gem::Net::HTTP does not compress the body of a request before sending. + # + # By default, \Gem::Net::HTTP adds header <tt>'Accept-Encoding'</tt> + # to a new {request object}[rdoc-ref:Gem::Net::HTTPRequest]: + # + # Gem::Net::HTTP::Get.new(uri)['Accept-Encoding'] + # # => "gzip;q=1.0,deflate;q=0.6,identity;q=0.3" + # + # This requests the server to zip-encode the response body if there is one; + # the server is not required to do so. + # + # \Gem::Net::HTTP does not automatically decompress a response body + # if the response has header <tt>'Content-Range'</tt>. + # + # Otherwise decompression (or not) depends on the value of header + # {Content-Encoding}[https://en.wikipedia.org/wiki/List_of_HTTP_header_fields#content-encoding-response-header]: + # + # - <tt>'deflate'</tt>, <tt>'gzip'</tt>, or <tt>'x-gzip'</tt>: + # decompresses the body and deletes the header. + #
