httpDirectory :: Manager -> String -> IO [Text] Source #
List the file links (hrefs) in an http directory
Raises an error if the http request fails.
Note if the directory (webpage) url is redirected to a different path
you may need to use httpRedirect to determine
the actual final url prefix for relative links
(files).
(Filters "non-files/subdirs" @since 0.1.4 (before that was just httpRawDirectory)
httpRawDirectory :: Manager -> String -> IO [Text] Source #
List all the hrefs in an http directory html file.
Raises an error if the http request fails.
Note if the directory (webpage) url is redirected to a different path
you may need to use httpRedirect to determine
the actual final url prefix for relative links
(files).
Since: 0.1.4
httpFileSize :: Manager -> String -> IO (Maybe Integer) Source #
Try to get the filesize (Content-Length field) of an http file
Raises an error if the http request fails.
httpLastModified :: Manager -> String -> IO (Maybe UTCTime) Source #
Try to get the modification time (Last-Modified field) of an http file
Raises an error if the http request fails.
Since: 0.1.1
httpManager :: IO Manager Source #
alias for 'newManager tlsManagerSettings' so one does not need to import http-client etc
Since: 0.1.2
httpRedirect :: Manager -> String -> IO (Maybe ByteString) Source #
Return final redirect for an url
httpRedirect' :: String -> IO (Maybe ByteString) Source #
Like httpRedirect but uses own Manager.
Since: 0.1.4
httpRedirects :: Manager -> String -> IO [ByteString] Source #
Returns the list of http redirects for an url in reverse order (ie last redirect is listed first)
