Query string

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 #

Convert Query

Convert Query

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

.
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"
. - It decodes
'+'
characters to' '
parseSimpleQuery :: ByteString -> SimpleQuery Source #
Parse SimpleQuery
from a ByteString
.
Escape only parts
renderQueryPartialEscape Source #
:: Bool | prepend question mark? |
-> PartialEscapeQuery | |

renderQueryBuilderPartialEscape Source #

Convert PartialEscapeQuery

data EscapeItem Source #
For some URIs characters must not be URI encoded,
e.g. '+'
or ':'
in q=a+language:haskell+created:2009-01-01..2009-02-01&sort=stars
The character list unreservedPI instead of unreservedQS would solve this.
But we explicitly decide what part to encode.
This is mandatory when searching for '+'
: q=%2B+language:haskell
.

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

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.

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
:: Bool | Whether input is in query string. True: Query string, False: Path element |
-> ByteString | |
-> Builder |
Percent-encoding for URLs (using Builder
).
:: Bool | Whether to decode |
-> ByteString | The ByteString to encode as URL |
-> ByteString | The encoded URL |
Percent-encoding for URLs.
