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.

renderQuery Source #

Arguments

:: Bool

prepend question mark?

-> Query 
-> ByteString 

Convert Query to ByteString.

renderQueryBuilder Source #

Arguments

:: Bool

prepend a question mark?

-> Query 
-> Builder 

Convert Query to a Builder.

renderSimpleQuery Source #

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).

queryTextToQuery :: QueryText -> Query Source #

Convert QueryText to Query.

queryToQueryText :: Query -> QueryText Source #

Convert Query to QueryText (leniently decoding the UTF-8).

renderQueryText Source #

Arguments

:: Bool

prepend a question mark?

-> QueryText 
-> Builder 

Convert QueryText to a Builder.

parseQueryText :: ByteString -> QueryText Source #

Parse QueryText from a ByteString. See parseQuery for details.

Generalized query types

class QueryLike a where Source #

Types which can, and commonly are, converted to Query are in this class.

You can use lists of simple key value pairs, with ByteString (strict, or lazy: ByteString), Text, or String as the key/value types. You can also have the value type lifted into a Maybe to support keys without values; and finally it is possible to put each pair into a Maybe for key-value pairs that aren't always present.

toQuery :: a -> Query Source #

Methods

toQuery :: [(k, v)] -> Query Source #

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 ""
"/"

encodePath :: [Text] -> Query -> Builder Source #

Encode a whole path (path segments + query).

decodePath :: ByteString -> ([Text], Query) Source #

Decode a whole path (path segments + query).

URL encoding / decoding

urlEncodeBuilder Source #

-> ByteString 
-> Builder 

Percent-encoding for URLs (using Builder).

urlEncode Source #
