CgiRequest and TestRequest provide concrete implementations.
HTTP_METHODS | = | %w(get head put post delete options) | ||
HTTP_METHOD_LOOKUP | = | HTTP_METHODS.inject({}) { |h, m| h[m] = h[m.upcase] = m.to_sym; | ||
TRUSTED_PROXIES | = | /^127\.0\.0\.1$|^(10|172\.(1[6-9]|2[0-9]|30|31)|192\.168)\./i | Which IP addresses are "trusted proxies" that can be stripped from the right-hand-side of X-Forwarded-For | |
MULTIPART_BOUNDARY | = | %r|\Amultipart/form-data.*boundary=\"?([^\";,]+)\"?|n | ||
EOL | = | "\015\012" |
env | [R] | The hash of environment variables for this request, such as { ‘RAILS_ENV’ => ‘production’ }. |
The request body is an IO input stream. If the RAW_POST_DATA environment variable is already set, wrap it in a StringIO.
The MIME type of the HTTP request, such as Mime::XML.
For backward compatibility, the post \format is extracted from the X-Post-Data-Format HTTP header if present.
Returns the \domain part of a \host, such as "rubyonrails.org" in "www.rubyonrails.org". You can specify a different tld_length, such as 2 to catch rubyonrails.co.uk in "www.rubyonrails.co.uk".
Returns the Mime type for the \format used in the request.
GET /posts/5.xml | request.format => Mime::XML GET /posts/5.xhtml | request.format => Mime::HTML GET /posts/5 | request.format => Mime::HTML or MIME::JS, or request.accepts.first depending on the value of <tt>ActionController::Base.use_accept_header</tt>
Sets the \format by string extension, which can be used to force custom formats that are not controlled by the extension.
class ApplicationController < ActionController::Base before_filter :adjust_format_for_iphone private def adjust_format_for_iphone request.format = :iphone if request.env["HTTP_USER_AGENT"][/iPhone/] end end
Check response freshness (Last-Modified and ETag) against request If-Modified-Since and If-None-Match conditions. If both headers are supplied, both must match, or the request is not considered fresh.
Provides access to the request‘s HTTP headers, for example:
request.headers["Content-Type"] # => "text/plain"
The HTTP request \method as a lowercase symbol, such as :get. Note, HEAD is returned as :get since the two are functionally equivalent from the application‘s perspective.
Returns the interpreted \path to requested resource after all the installation directory of this application was taken into account.
Returns a hash with the \parameters used to form the \path of the request. Returned hash keys are strings:
{'action' => 'my_action', 'controller' => 'my_controller'}
See symbolized_path_parameters for symbolized keys.
Read the request \body. This is useful for web services that need to work with raw requests directly.
Determines 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 if REMOTE_ADDR is a proxy. HTTP_X_FORWARDED_FOR may be a comma- delimited list in the case of multiple chained proxies; the last address which is not trusted is the originating IP.
The true HTTP request \method as a lowercase symbol, such as :get. UnknownHttpMethod is raised for invalid methods not listed in ACCEPTED_HTTP_METHODS.
Returns the request URI, accounting for server idiosyncrasies. WEBrick includes the full URL. IIS leaves REQUEST_URI blank.
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".
Returns true if the request‘s "X-Requested-With" header contains "XMLHttpRequest". (The Prototype Javascript library sends this header with every Ajax request.)
The raw content type string. Use when you need parameters such as charset or boundary which aren‘t included in the content_type MIME type. Overridden by the X-POST_DATA_FORMAT header for backward compatibility.
