Common

data ClassicAppSpec Source #

Constructors

ClassicAppSpec
Fields softwareName :: ByteString Name specified to Server: in HTTP response. statusFileDir :: Path A function to get HTTP's GMT Date.

defaultClassicAppSpec :: ClassicAppSpec Source #

Default value for ClassicAppSpec. softwareName is "Classic". dater calls epochTime for every request. statusFileDir is "/usr/local/share/html/status/".

data StatusInfo Source #

Constructors

StatusByteString ByteString	HTTP status body is created from `ByteString`.
StatusFile Path Integer	HTTP status body is created from `FilePath`.
StatusNone	No HTTP status body.

Files

data FileAppSpec Source #

Constructors

FileAppSpec
Fields indexFile :: Path A file name of an index file. isHTML :: Path -> Bool Whether this is an HTML or not.

defaultFileAppSpec :: FileAppSpec Source #

Default value for defaultFileAppSpec. indexFile is "index.html". isHTML matches "*.html" and "*.html".

data FileRoute Source #

Constructors

FileRoute
Fields fileSrc :: Path Path prefix to be matched to `rawPathInfo`. fileDst :: Path Path prefix to an actual file system.

Show FileRoute Source #

Eq FileRoute Source #
Instance details Defined in Network.Wai.Application.Classic.Types Methods (==) :: FileRoute -> FileRoute -> Bool # (/=) :: FileRoute -> FileRoute -> Bool #

fileApp :: ClassicAppSpec -> FileAppSpec -> FileRoute -> Application Source #

Handle GET and HEAD for a static file.

If pathInfo ends with '/', indexFile is automatically added. In this case, "Acceptable-Language:" is also handled. Suppose indexFile is "index.html" and if the value is "ja,en", then "index.html.ja", "index.html.en", and "index.html" are tried to be opened in order.

If pathInfo does not end with '/' and a corresponding index file exist, redirection is specified in HTTP response.

Directory contents are NOT automatically listed. To list directory contents, an index file must be created beforehand.

The following HTTP headers are handled: Acceptable-Language:, If-Modified-Since:, Range:, If-Range:, If-Unmodified-Since:.

Redirect

data RedirectRoute Source #

Constructors

RedirectRoute
Fields redirectSrc :: Path Path prefix to be matched to `rawPathInfo`. redirectDst :: Path Path prefix to an actual file system.

CGI

data CgiAppSpec Source #

Constructors

CgiAppSpec
Fields indexCgi :: Path A file name of the default CGI.

defaultCgiAppSpec :: CgiAppSpec Source #

Default value for defaultCgiAppSpec. indexCgi is "index.cgi".

data CgiRoute Source #

CgiRoute
Fields cgiSrc :: Path Path prefix to be matched to `rawPathInfo`. cgiDst :: Path Path prefix to an actual file system.

cgiApp :: ClassicAppSpec -> CgiAppSpec -> CgiRoute -> Application Source #

Handle GET and POST for CGI.

The program to link this library must ignore SIGCHLD as follows:

  installHandler sigCHLD Ignore Nothing

Reverse Proxy

data RevProxyAppSpec Source #

Constructors

RevProxyAppSpec
Fields revProxyManager :: Manager Connection manager

data RevProxyRoute Source #

Constructors

RevProxyRoute
Fields revProxySrc :: Path Path prefix to be matched to `rawPathInfo`. revProxyDst :: Path Destination path prefix. revProxyDomain :: ByteString Destination domain name. revProxyPort :: Int Destination port number.

Relaying any requests as reverse proxy.

Path

fromString :: IsString a => String -> a #

isSuffixOf :: Path -> Path -> Bool Source #

(</>) :: Path -> Path -> Path Source #

Appending with the file separator.

>>> "/foo" </> "bar"
"/foo/bar"
>>> "/foo/" </> "bar"
"/foo/bar"
>>> "/foo" </> "/bar"
"/foo/bar"
>>> "/foo/" </> "/bar"

True
>>> hasTrailingPathSeparator "/foo/bar"
False

type Path = ByteString Source #

File path.

pathString :: Path -> String Source #

(<\>) :: Path -> Path -> Path Source #

Removing prefix. The prefix of the second argument is removed from the first argument.

>>> "foobar" <\> "foo"
"bar"
>>> "foo" <\> "foobar"
""
>>> "foobar" <\> "baz"
"bar"

breakAtSeparator :: Path -> (Path, Path) Source #

Breaking at the first path separator.

>>> breakAtSeparator "/foo/bar/baz"
("","/foo/bar/baz")
>>> breakAtSeparator "foo/bar/baz"
("foo","/bar/baz")
>>> breakAtSeparator "foo"
("foo","")

hasLeadingPathSeparator :: Path -> Bool Source #

Checking if the path ends with the path separator.

>>> hasLeadingPathSeparator "/foo/bar"
True
>>> hasLeadingPathSeparator "foo/bar"
False
