def put?
  HTTP_METHOD_LOOKUP[request_method] == :put
end
query_parameters()
Alias for: GET
raw_post()

Read the request body. This is useful for web services that need to work with raw requests directly.

Source: show | on GitHub 

# File actionpack/lib/action_dispatch/http/request.rb, line 225
def raw_post
  unless @env.include? 'RAW_POST_DATA'
    raw_post_body = body

def remote_ip
  @remote_ip ||= (@env["action_dispatch.remote_ip"] || ip).to_s
end
request_method()

Returns the HTTP method that the application should see. In the case where the method was overridden by a middleware (for instance, if a HEAD request was converted to a #GET, or if a _method parameter was used to determine the method the application should use), this method returns the overridden value, not the original.

Source: show | on GitHub 

# File actionpack/lib/action_dispatch/http/request.rb, line 91
def request_method
  @request_method ||= check_method(env["REQUEST_METHOD"])
end
request_method_symbol()

Source: show | on GitHub 

# File actionpack/lib/action_dispatch/http/request.rb, line 96
def request_method_symbol
  HTTP_METHOD_LOOKUP[request_method]

request_parameters()
Alias for: POST
reset_session()

TODO This should be broken apart into AD::Request::Session and probably be included by the session middleware.

Source: show | on GitHub 

# File actionpack/lib/action_dispatch/http/request.rb, line 255
def reset_session
  if session && session.respond_to?(:destroy)
    session.destroy

    self.session = {}
  end
  @env['action_dispatch.request.flash_hash'] = nil
end
server_software()

Returns the lowercase name of the HTTP server software.

Source: show | on GitHub 

# File actionpack/lib/action_dispatch/http/request.rb, line 219
def server_software
  (@env['SERVER_SOFTWARE'] && /^([a-zA-Z]+)/ =~ @env['SERVER_SOFTWARE']) ? $1.downcase : nil
end
session_options=(options)

Source: show | on GitHub 

# File actionpack/lib/action_dispatch/http/request.rb, line 268
def session_options=(options)
  Session::Options.set @env, options
end
uuid()

Returns the unique request id, which is based off either the X-Request-Id header that can be generated by a firewall, load balancer, or web server or by the RequestId middleware (which sets the action_dispatch.request_id environment variable).

This unique ID is useful for tracing a request from end-to-end as part of logging or debugging. This relies on the rack variable set by the ActionDispatch::RequestId middleware.

Source: show | on GitHub 

# File actionpack/lib/action_dispatch/http/request.rb, line 214
def uuid
  @uuid ||= env["action_dispatch.request_id"]
end
xhr?()
Alias for: xml_http_request?
xml_http_request?()

Returns true if the “X-Requested-With” header contains “XMLHttpRequest” (case-insensitive). All major JavaScript libraries send this header with every Ajax request.

Also aliased as: xhr?

Source: show | on GitHub 

# File actionpack/lib/action_dispatch/http/request.rb, line 194
def xml_http_request?
  @env['HTTP_X_REQUESTED_WITH'] =~ /XMLHttpRequest/i
