form_data?()

Determine whether the request body contains form-data by checking the request Content-Type for one of the media-types: “application/x-www-form-urlencoded” or “multipart/form-data”. The list of form-data media types can be modified through the FORM_DATA_MEDIA_TYPES array.

A request body is not assumed to contain form-data when no Content-Type header is provided and the #request_method is #POST.

Source: show | on GitHub 

# File actionpack/lib/action_dispatch/http/request.rb, line 319
def form_data?
  FORM_DATA_MEDIA_TYPES.include?(media_type)
end

Source: show | on GitHub 

# File actionpack/lib/action_dispatch/http/request.rb, line 218

request.headers["Content-Type"] # => "text/plain"

Source: show | on GitHub 

# File actionpack/lib/action_dispatch/http/request.rb, line 196

  @headers ||= Http::Headers.new(self)

# get "/articles"
request.media_type # => "application/x-www-form-urlencoded"

Source: show | on GitHub 

# File actionpack/lib/action_dispatch/http/request.rb, line 234
def media_type
  content_mime_type.to_s
end
method()

Returns the original value of the environment's REQUEST_METHOD, even if it was overridden by middleware. See request_method for more information.

Source: show | on GitHub 

# File actionpack/lib/action_dispatch/http/request.rb, line 184
def method
  @method ||= check_method(get_header("rack.methodoverride.original_method") || get_header("REQUEST_METHOD"))
end
method_symbol()

Returns a symbol form of the method

Source: show | on GitHub 

# File actionpack/lib/action_dispatch/http/request.rb, line 189
def method_symbol
  HTTP_METHOD_LOOKUP[method]
end
original_fullpath()

Returns a String with the last requested path including their params.

# get '/foo'
request.original_fullpath # => '/foo'

# get '/foo?bar'
request.original_fullpath # => '/foo?bar'

Source: show | on GitHub

def original_url
  base_url + original_fullpath
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 291
def raw_post
  unless has_header? "RAW_POST_DATA"
    raw_post_body = body

    raw_post_body.rewind if raw_post_body.respond_to?(:rewind)
  end
  get_header "RAW_POST_DATA"
end
remote_ip()

Returns the IP address of client as a String, usually set by the RemoteIp middleware.

Source: show | on GitHub 

# File actionpack/lib/action_dispatch/http/request.rb, line 258
def remote_ip
  @remote_ip ||= (get_header("action_dispatch.remote_ip") || ip).to_s
end
remote_ip=(remote_ip)

Source: show | on GitHub 

# File actionpack/lib/action_dispatch/http/request.rb, line 262
def remote_ip=(remote_ip)
  set_header "action_dispatch.remote_ip".freeze, remote_ip
end
request_id()

Returns the unique request id, which is based on 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.

Also aliased as: uuid

Source: show | on GitHub 

# File actionpack/lib/action_dispatch/http/request.rb, line 274
def request_id
  get_header ACTION_DISPATCH_REQUEST_ID
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 131
def request_method
  @request_method ||= check_method(super)
end

def request_parameters=(params)
  raise if params.nil?
  set_header("action_dispatch.request.request_parameters".freeze, params)
end
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 329
def reset_session
  if session && session.respond_to?(:destroy)
    session.destroy
  else
    self.session = {}
  end
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 285

xml_http_request?()

Also aliased as: xhr?

Source: show | on GitHub 

# File actionpack/lib/action_dispatch/http/request.rb, line 246
def xml_http_request?
  get_header("HTTP_X_REQUESTED_WITH") =~ /XMLHttpRequest/i
