The supported--- flags are as follows:------ [@AI_PASSIVE@] If no 'HostName' value is provided, the network--- address in each 'SockAddr'--- will be left as a "wild card", i.e. as either 'iNADDR_ANY'--- or 'iN6ADDR_ANY'. This is useful for server applications that--- will accept connections from any client.------ [@AI_CANONNAME@] The 'addrCanonName' field of the first returned--- 'AddrInfo' will contain the "canonical name" of the host.------ [@AI_NUMERICHOST@] The 'HostName' argument /must/ be a numeric--- address in string form, and network name lookups will not be--- attempted.--- --- /Note/: Although the following flags are required by RFC 3493, they--- may not have an effect on all platforms, because the underlying--- network stack may not support them. To see whether a flag from the--- list below will have any effect, call 'addrInfoFlagImplemented'.------ [@AI_NUMERICSERV@] The 'ServiceName' argument /must/ be a port--- number in string form, and service name lookups will not be--- attempted.------ [@AI_ADDRCONFIG@] The list of returned 'AddrInfo' values will--- only contain IPv4 addresses if the local system has at least--- one IPv4 interface configured, and likewise for IPv6.------ [@AI_V4MAPPED@] If an IPv6 lookup is performed, and no IPv6--- addresses are found, IPv6-mapped IPv4 addresses will be--- returned.------ [@AI_ALL@] If 'AI_ALL' is specified, return all matching IPv6 and--- IPv4 addresses. Otherwise, this flag has no effect.--- --- You must provide a 'Just' value for at least one of the 'HostName'--- or 'ServiceName' arguments. 'HostName' can be either a numeric--- network address (dotted quad for IPv4, colon-separated hex for--- IPv6) or a hostname. In the latter case, its addresses will be--- looked up unless 'AI_NUMERICHOST' is specified as a hint. If you--- do not provide a 'HostName' value /and/ do not set 'AI_PASSIVE' as--- a hint, network addresses in the result will contain the address of--- the loopback interface.------ If the query fails, this function throws an IO exception instead of--- returning an empty list. Otherwise, it returns a non-empty list--- of 'AddrInfo' values.------ There are several reasons why a query might result in several--- values. For example, the queried-for host could be multihomed, or--- the service might be available via several protocols.------ Note: the order of arguments is slightly different to that defined--- for @getaddrinfo@ in RFC 2553.

The internal--- representation of URI has been changed so that URI strings are more--- completely preserved when round-tripping to a URI value and back.------ In addition, four methods are provided for parsing different--- kinds of URI string (as noted in RFC3986):--- 'parseURI',--- 'parseURIReference',--- 'parseRelativeReference' and--- 'parseAbsoluteURI'.------ Further, four methods are provided for classifying different--- kinds of URI string (as noted in RFC3986):--- 'isURI',--- 'isURIReference',--- 'isRelativeReference' and--- 'isAbsoluteURI'.------ The long-standing official reference for URI handling was RFC2396 [1],--- as updated by RFC 2732 [2], but this was replaced by a new specification,--- RFC3986 [3] in January 2005. This latter specification has been used--- as the primary reference for constructing the URI parser implemented--- here, and it is intended that there is a direct relationship between--- the syntax definition in that document and this parser implementation.------ RFC 1808 [4] contains a number of test cases for relative URI handling.--- Dan Connolly's Python module @uripath.py@ [5] also contains useful details--- and test cases.------ Some of the code has been copied from the previous GHC implementation,--- but the parser is replaced with one that performs more complete--- syntax checking of the URI itself, according to RFC3986 [3].------ References------ (1) <http://www.ietf.org/rfc/rfc2396.txt>------ (2) <http://www.ietf.org/rfc/rfc2732.txt>------ (3) <http://www.ietf.org/rfc/rfc3986.txt>------ (4) <http://www.ietf.org/rfc/rfc1808.txt>------ (5) <http://www.w3.org/2000/10/swap/uripath.py>--------------------------------------------------------------------------------------module Network.URI- ( -- * The URI type- URI(..)- , URIAuth(..)- , nullURI- -- * Parsing- , parseURI -- :: String -> Maybe URI- , parseURIReference -- :: String -> Maybe URI- , parseRelativeReference -- :: String -> Maybe URI- , parseAbsoluteURI -- :: String -> Maybe URI- -- * Test for strings containing various kinds of URI- , isURI- , isURIReference- , isRelativeReference- , isAbsoluteURI- , isIPv6address- , isIPv4address- -- * Relative URIs- , relativeTo -- :: URI -> URI -> Maybe URI- , nonStrictRelativeTo -- :: URI -> URI -> Maybe URI- , relativeFrom -- :: URI -> URI -> URI- -- * Operations on URI strings- -- | Support for putting strings into URI-friendly- -- escaped format and getting them back again.- -- This can't be done transparently in all cases, because certain- -- characters have different meanings in different kinds of URI.- -- The URI spec [3], section 2.4, indicates that all URI components- -- should be escaped before they are assembled as a URI:- -- \"Once produced, a URI is always in its percent-encoded form\"- , uriToString -- :: URI -> ShowS- , isReserved, isUnreserved -- :: Char -> Bool- , isAllowedInURI, isUnescapedInURI -- :: Char -> Bool- , escapeURIChar -- :: (Char->Bool) -> Char -> String- , escapeURIString -- :: (Char->Bool) -> String -> String- , unEscapeString -- :: String -> String- -- * URI Normalization functions- , normalizeCase -- :: String -> String- , normalizeEscape -- :: String -> String- , normalizePathSegments -- :: String -> String- -- * Deprecated functions- , parseabsoluteURI -- :: String -> Maybe URI- , escapeString -- :: String -> (Char->Bool) -> String- , reserved, unreserved -- :: Char -> Bool- , scheme, authority, path, query, fragment- )-where--import Text.ParserCombinators.Parsec- ( GenParser(..), ParseError(..)- , parse, (<|>), (<?>), try- , option, many, many1, count, notFollowedBy, lookAhead- , char, satisfy, oneOf, string, letter, digit, hexDigit, eof- , unexpected- )--import Data.Char( ord, chr, isHexDigit, isSpace, toLower, toUpper, digitToInt )--import Debug.Trace( trace )--import Numeric( showIntAtBase )--import Data.Maybe( isJust )--import Control.Monad( MonadPlus(..) )--#ifdef __GLASGOW_HASKELL__-import Data.Typeable ( Typeable )-# if MIN_VERSION_base(4,0,0)-import Data.Data ( Data )-# else-import Data.Generics ( Data )-# endif-#else-import Data.Typeable ( Typeable(..), TyCon, mkTyCon, mkTyConApp )-#endif----------------------------------------------------------------- The URI datatype----------------------------------------------------------------- |Represents a general universal resource identifier using--- its component parts.------ For example, for the URI------ > foo://anonymous@www.haskell.org:42/ghc?query#frag------ the components are:----data URI = URI- { uriScheme :: String -- ^ @foo:@- , uriAuthority :: Maybe URIAuth -- ^ @\/\/anonymous\@www.haskell.org:42@- , uriPath :: String -- ^ @\/ghc@- , uriQuery :: String -- ^ @?query@- , uriFragment :: String -- ^ @#frag@- } deriving (Eq-#ifdef __GLASGOW_HASKELL__- , Typeable, Data-#endif- )--#ifndef __GLASGOW_HASKELL__-uriTc :: TyCon-uriTc = mkTyCon "URI"--instance Typeable URI where- typeOf _ = mkTyConApp uriTc []-#endif---- |Type for authority value within a URI-data URIAuth = URIAuth- { uriUserInfo :: String -- ^ @anonymous\@@- , uriRegName :: String -- ^ @www.haskell.org@- , uriPort :: String -- ^ @:42@- } deriving (Eq-#ifdef __GLASGOW_HASKELL__- , Typeable, Data-#endif- )--#ifndef __GLASGOW_HASKELL__-uriAuthTc :: TyCon-uriAuthTc = mkTyCon "URIAuth"--instance Typeable URIAuth where- typeOf _ = mkTyConApp uriAuthTc []-#endif---- |Blank URI-nullURI :: URI-nullURI = URI- { uriScheme = ""- , uriAuthority = Nothing- , uriPath = ""- , uriQuery = ""- , uriFragment = ""- }---- URI as instance of Show.
