Description

WAI (Web Application Interface) Application for static files and CGI.

Synopsis

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.

Instances

Eq StatusInfo Source #
Methods (==) :: StatusInfo -> StatusInfo -> Bool # (/=) :: StatusInfo -> StatusInfo -> Bool #
Show StatusInfo Source #
Methods showsPrec :: Int -> StatusInfo -> ShowS # show :: StatusInfo -> String # showList :: [StatusInfo] -> ShowS #

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.

Instances

Eq FileRoute Source #
Methods (==) :: FileRoute -> FileRoute -> Bool # (/=) :: FileRoute -> FileRoute -> Bool #
Show FileRoute Source #
Methods showsPrec :: Int -> FileRoute -> ShowS # show :: FileRoute -> String # showList :: [FileRoute] -> ShowS #

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.

Instances

Eq RedirectRoute Source #
Methods (==) :: RedirectRoute -> RedirectRoute -> Bool # (/=) :: RedirectRoute -> RedirectRoute -> Bool #
Show RedirectRoute Source #
Methods showsPrec :: Int -> RedirectRoute -> ShowS # show :: RedirectRoute -> String # showList :: [RedirectRoute] -> ShowS #

redirectApp :: ClassicAppSpec -> RedirectRoute -> Application Source #

CGI

data CgiAppSpec Source #

Constructors

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

Instances

Eq CgiAppSpec Source #
Methods (==) :: CgiAppSpec -> CgiAppSpec -> Bool # (/=) :: CgiAppSpec -> CgiAppSpec -> Bool #
Show CgiAppSpec Source #
Methods showsPrec :: Int -> CgiAppSpec -> ShowS # show :: CgiAppSpec -> String # showList :: [CgiAppSpec] -> ShowS #

defaultCgiAppSpec :: CgiAppSpec Source #

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

data CgiRoute Source #

Constructors

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

Instances

Eq CgiRoute Source #
Methods (==) :: CgiRoute -> CgiRoute -> Bool # (/=) :: CgiRoute -> CgiRoute -> Bool #
Show CgiRoute Source #
Methods showsPrec :: Int -> CgiRoute -> ShowS # show :: CgiRoute -> String # showList :: [CgiRoute] -> ShowS #

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.

Instances

Eq RevProxyRoute Source #
Methods (==) :: RevProxyRoute -> RevProxyRoute -> Bool # (/=) :: RevProxyRoute -> RevProxyRoute -> Bool #
Show RevProxyRoute Source #
Methods showsPrec :: Int -> RevProxyRoute -> ShowS # show :: RevProxyRoute -> String # showList :: [RevProxyRoute] -> ShowS #

revProxyApp :: ClassicAppSpec -> RevProxyAppSpec -> RevProxyRoute -> Application Source #

Relaying any requests as reverse proxy.

Path

type Path = ByteString Source #

File path.

pathString :: Path -> String Source #

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

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

Appending with the file separator.

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

(<\>) :: 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"

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