Documentation

Fields

• requestMethod :: Method

  Request method such as GET.

• httpVersion :: HttpVersion

  HTTP version such as 1.1.

• rawPathInfo :: ByteString

  Extra path information sent by the client. The meaning varies slightly depending on backend; in a standalone server setting, this is most likely all information after the domain name. In a CGI application, this would be the information following the path to the CGI executable itself.

  Middlewares and routing tools should not modify this raw value, as it may be used for such things as creating redirect destinations by applications. Instead, if you are writing a middleware or routing framework, modify the pathInfo instead. This is the approach taken by systems like Yesod subsites.

  Note: At the time of writing this documentation, there is at least one system (Network.Wai.UrlMap from wai-extra) that does not follow the above recommendation. Therefore, it is recommended that you test the behavior of your application when using rawPathInfo and any form of library that might modify the Request.

• rawQueryString :: ByteString

  If no query string was specified, this should be empty. This value will include the leading question mark. Do not modify this raw value - modify queryString instead.

• requestHeaders :: RequestHeaders

  A list of headers (a pair of key and value) in an HTTP request.

• isSecure :: Bool

  Was this request made over an SSL connection?

  Note that this value will not tell you if the client originally made this request over SSL, but rather whether the current connection is SSL. The distinction lies with reverse proxies. In many cases, the client will connect to a load balancer over SSL, but connect to the WAI handler without SSL. In such a case, isSecure will be False, but from a user perspective, there is a secure connection.

• remoteHost :: SockAddr

  The client's host information.

• pathInfo :: [Text]

  Path info in individual pieces - the URL without a hostname/port and without a query string, split on forward slashes.

• queryString :: Query

  Parsed query string information.

• requestBody :: IO ByteString

  Deprecated: requestBody's name is misleading because it only gets a partial chunk of the body. Use getRequestBodyChunk instead.

  Get the next chunk of the body. Returns empty when the body is fully consumed. Since 3.2.2, this is deprecated in favor of getRequestBodyChunk.

• vault :: Vault

  A location for arbitrary data to be shared by applications and middleware.

• requestBodyLength :: RequestBodyLength

  The size of the request body. In the case of a chunked request body, this may be unknown.

  Since 1.4.0

• requestHeaderHost :: Maybe ByteString

  The value of the Host header in a HTTP request.

  Since 2.0.0

• requestHeaderRange :: Maybe ByteString

  The value of the Range header in a HTTP request.

  Since 2.0.0

• requestHeaderReferer :: Maybe ByteString

  The value of the Referer header in a HTTP request.

  Since 3.2.0

• requestHeaderUserAgent :: Maybe ByteString

  The value of the User-Agent header in a HTTP request.

  Since 3.2.0
