Query string
type QueryItem = (ByteString, Maybe ByteString) Source #
Query item
type Query = [QueryItem] Source #
Query.
General form: a=b&c=d, but if the value is Nothing, it becomes a&c=d.
type SimpleQueryItem = (ByteString, ByteString) Source #
Simplified Query item type without support for parameter-less items.
type SimpleQuery = [SimpleQueryItem] Source #
Simplified Query type without support for parameter-less items.
simpleQueryToQuery :: SimpleQuery -> Query Source #
Convert SimpleQuery to Query.
Arguments
| :: Bool | prepend question mark? |
| -> Query | |
| -> ByteString |
Convert Query to ByteString.
Convert Query to a Builder.
Arguments
| :: Bool | prepend question mark? |
| -> SimpleQuery | |
| -> ByteString |
Convert SimpleQuery to ByteString.
parseQuery :: ByteString -> Query Source #
Split out the query string into a list of keys and values. A few importants points:
- The result returned is still bytestrings, since we perform no character decoding here. Most likely, you will want to use UTF-8 decoding, but this is left to the user of the library.
- Percent decoding errors are ignored. In particular, "%Q" will be output as "%Q".
parseSimpleQuery :: ByteString -> SimpleQuery Source #
Parse SimpleQuery from a ByteString.
Text query string (UTF8 encoded)
type QueryText = [(Text, Maybe Text)] Source #
Like Query, but with Text instead of ByteString (UTF8-encoded).
queryToQueryText :: Query -> QueryText Source #
parseQueryText :: ByteString -> QueryText Source #
Parse QueryText from a ByteString. See parseQuery for details.
Path segments
encodePathSegments :: [Text] -> Builder Source #
Encodes a list of path segments into a valid URL fragment.
This function takes the following three steps:
- UTF-8 encodes the characters.
- Performs percent encoding on all unreserved characters, as well as :@=+$,
- Prepends each segment with a slash.
For example:
encodePathSegments [\"foo\", \"bar\", \"baz\"]
"/foo/bar/baz"
encodePathSegments [\"foo bar\", \"baz\/bin\"]
"/foo%20bar/baz%2Fbin"
encodePathSegments [\"שלום\"]
"/%D7%A9%D7%9C%D7%95%D7%9D"
Huge thanks to Jeremy Shaw who created the original implementation of this function in web-routes and did such thorough research to determine all correct escaping procedures.
decodePathSegments :: ByteString -> [Text] Source #
Parse a list of path segments from a valid URL fragment.
encodePathSegmentsRelative :: [Text] -> Builder Source #
Like encodePathSegments, but without the initial slash.
Path (segments + query string)
extractPath :: ByteString -> ByteString Source #
Extract whole path (path segments + query) from a RFC 2616 Request-URI.
>>>extractPath "/path""/path"
>>>extractPath "http://example.com:8080/path""/path"
>>>extractPath "http://example.com""/"
>>>extractPath """/"
decodePath :: ByteString -> ([Text], Query) Source #
Decode a whole path (path segments + query).
URL encoding / decoding
Arguments
| :: Bool | Whether input is in query string. True: Query string, False: Path element |
| -> ByteString | |
| -> Builder |
Percent-encoding for URLs (using Builder).
Arguments
| :: Bool | Whether to decode |
| -> ByteString | The ByteString to encode as URL |
| -> ByteString | The encoded URL |
Percent-encoding for URLs.
Arguments
| :: Bool | Whether to decode |
| -> ByteString | |
| -> ByteString |
Percent-decoding.
