_GET :: Prism' Request Request Source

Prism' to filter GET Requests.

>>> dummyRequest ^? _GET <&> method
Just "GET"
>>> dummyRequestForm ^? _GET <&> method
Nothing

_POST :: Prism' Request Request Source

Prism' to filter for POST Requests.

>>> dummyRequest ^? _POST <&> method
Nothing
>>> dummyRequestForm ^? _POST <&> method
Just "POST"

params :: Traversal' Request MultiMap Source

This Traversal lets you traverse every HTTP parameter regardless of whether it's present in the query string or in the form encoded body of a POST Request. In the rare case where there are HTTP parameters in both, every parameter is still being traversed starting from the /query string/.

You might want to use param for traversing a specific parameter.

>>> let request = dummyRequestForm & query . at "name" ?~ ["hello", "out"] & form  . at "name" ?~ ["there"]
>>> foldOf params request ^? ix "name"
Just ["hello","out","there"]

Testing

dummyRequest :: Request Source

An empty GET request useful for testing.

dummyRequestForm :: Request Source

An empty POST request with an empty form encoded body useful for testing.
