# URI

## Query string

type QueryItem = (ByteString, Maybe ByteString) #

Query item

type Query = [QueryItem] #

Query.

General form: a=b&c=d, but if the value is Nothing, it becomes a&c=d.

type SimpleQueryItem = (ByteString, ByteString) #

Simplified Query item type without support for parameter-less items.

type SimpleQuery = [SimpleQueryItem] #

Simplified Query type without support for parameter-less items.

simpleQueryToQuery :: SimpleQuery -> Query #

Convert `SimpleQuery` to `Query`.

renderQuery #

Arguments

:: Bool | prepend question mark?
-> Query |
-> ByteString |

Convert `Query` to `ByteString`.

renderQueryBuilder #

Arguments

:: Bool | prepend a question mark?
-> Query |
-> Builder |

Convert `Query` to a `Builder`.

renderSimpleQuery #

Arguments

:: Bool | prepend question mark?
-> SimpleQuery |
-> ByteString |

Convert `SimpleQuery` to `ByteString`.

parseQuery :: ByteString -> Query #

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 #

Parse `SimpleQuery` from a `ByteString`.

### Text query string (UTF8 encoded)

type QueryText = [(Text, Maybe Text)] #

Like Query, but with `Text` instead of `ByteString` (UTF8-encoded).

queryTextToQuery :: QueryText -> Query #

Convert `QueryText` to `Query`.

queryToQueryText :: Query -> QueryText #

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

renderQueryText #

Arguments

:: Bool | prepend a question mark?
-> QueryText |
-> Builder |

Convert `QueryText` to a `Builder`.

parseQueryText :: ByteString -> QueryText #

Parse `QueryText` from a `ByteString`. See `parseQuery` for details.

## Generalized query types

class QueryLike a where #

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.

Minimal complete definition

toQuery

Methods

toQuery :: a -> Query #

Convert to `Query`.

Instances

(QueryKeyLike k, QueryValueLike v) => QueryLike [Maybe (k, v)] # |
Methods toQuery :: [Maybe (k, v)] -> Query #
(QueryKeyLike k, QueryValueLike v) => QueryLike [(k, v)] # |
Methods toQuery :: [(k, v)] -> Query #

## Path segments

encodePathSegments :: [Text] -> Builder #

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] #

Parse a list of path segments from a valid URL fragment.

encodePathSegmentsRelative :: [Text] -> Builder #

Like encodePathSegments, but without the initial slash.

## Path (segments + query string)

extractPath :: ByteString -> ByteString #

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 #

Encode a whole path (path segments + query).

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

Decode a whole path (path segments + query).

## URL encoding / decoding

urlEncodeBuilder #

Arguments

:: Bool | Whether input is in query string. True: Query string, False: Path element
-> ByteString |
-> Builder |

Percent-encoding for URLs (using `Builder`).

urlEncode #

Arguments

:: Bool | Whether to decode `+` to ' '
-> ByteString | The ByteString to encode as URL
-> ByteString | The encoded URL

Percent-encoding for URLs.

urlDecode #

Arguments

:: Bool | Whether to decode `+` to ' '
-> ByteString |
-> ByteString |

Percent-decoding.
