Determine whether the body of a HTTP call is URL-encoded (default) or matches one of the registered param_parsers.

For backward compatibility, the post format is extracted from the X-Post-Data-Format HTTP header if present.

Receive the raw post data. This is useful for services such as REST, XMLRPC and SOAP which communicate over HTTP POST but don’t use the traditional parameter format.

     # File vendor/rails/actionpack/lib/action_controller/request.rb, line 127
127:     def raw_post
128:       @env['RAW_POST_DATA']
129:     end

Returns the path minus the web server relative installation directory. This can be set with the environment variable RAILS_RELATIVE_URL_ROOT. It can be automatically extracted for Apache setups. If the server is not Apache, this method returns an empty string.

[Source]

     # File vendor/rails/actionpack/lib/action_controller/request.rb, line 171
171:     def relative_url_root

178:           ''
179:       end
180:     end

Determine originating IP address. REMOTE_ADDR is the standard but will fail if the user is behind a proxy. HTTP_CLIENT_IP and/or HTTP_X_FORWARDED_FOR are set by proxies so check for these before falling back to REMOTE_ADDR. HTTP_X_FORWARDED_FOR may be a comma- delimited list in the case of multiple chained proxies; the first is the originating IP.

[Source]

     # File vendor/rails/actionpack/lib/action_controller/request.rb, line 93
 93:     def remote_ip
 94:       return @env['HTTP_CLIENT_IP'] if @env.include? 'HTTP_CLIENT_IP'
 95: 
 96:       if @env.include? 'HTTP_X_FORWARDED_FOR' then
 97:         remote_ips = @env['HTTP_X_FORWARDED_FOR'].split(',').reject do |ip|
 98:             ip =~ /^unknown$|^(10|172\.(1[6-9]|2[0-9]|30|31)|192\.168)\./i
 99:         end
100: 
101:         return remote_ips.first.strip unless remote_ips.empty?
102:       end
103: 
104:       @env['REMOTE_ADDR']
105:     end

Returns the request URI correctly, taking into account the idiosyncracies of the various servers.

[Source]

     # File vendor/rails/actionpack/lib/action_controller/request.rb, line 133
133:     def request_uri
134:       if uri = @env['REQUEST_URI']
135:         (%r{^\w+\://[^/]+(/.*|$)$} =~ uri) ? $1 : uri # Remove domain, which webrick puts into the request_uri.
136:       else  # REQUEST_URI is blank under IIS - get this from PATH_INFO and SCRIPT_NAME
137:         script_filename = @env['SCRIPT_NAME'].to_s.match(%r{[^/]+$})
138:         uri = @env['PATH_INFO']
139:         uri = uri.sub(/#{script_filename}\//, '') unless script_filename.nil?
140:         unless (env_qs = @env['QUERY_STRING']).nil? || env_qs.empty?
141:           uri << '?' << env_qs
142:         end
143:         uri
144:       end
145:     end

227:     def server_software
228:       (@env['SERVER_SOFTWARE'] && /^([a-zA-Z]+)/ =~ @env['SERVER_SOFTWARE']) ? $1.downcase : nil
229:     end

[Source]

     # File vendor/rails/actionpack/lib/action_controller/request.rb, line 153

155:     end

Returns the standard port number for this request’s protocol

[Source]

     # File vendor/rails/actionpack/lib/action_controller/request.rb, line 188
188:     def standard_port

191:         else 80
192:       end
193:     end

Returns all the subdomains as an array, so ["dev", "www"] would be returned for "dev.www.rubyonrails.org". You can specify a different tld_length, such as 2 to catch ["www"] instead of ["www", "rubyonrails"] in "www.rubyonrails.co.uk".

[Source]

     # File vendor/rails/actionpack/lib/action_controller/request.rb, line 118
118:     def subdomains(tld_length = 1)
119:       return [] unless host
120:       parts = host.split('.')
121:       parts[0..-(tld_length+2)]
122:     end

215:     end
xhr?()

Alias for xml_http_request?

Returns true if the request’s "X-Requested-With" header contains "XMLHttpRequest". (The Prototype Javascript library sends this header with every Ajax request.)

    # File vendor/rails/actionpack/lib/action_controller/request.rb, line 82
82:     def xml_http_request?
83:       not /XMLHttpRequest/i.match(@env['HTTP_X_REQUESTED_WITH']).nil?

26:       post? && post_format == :xml
27:     end
