Module plug that validates params against the schema defined for an operation.

If validation fails, the plug will send a 422 response with the reason as the body. This plug should always be run after OpenApiSpex.Plug.Cast, as it expects the params map to have atom keys and query params converted from strings to the appropriate types.

Example

defmodule MyApp.UserController do
  use Phoenix.Controller
  plug OpenApiSpex.Plug.Cast
  plug OpenApiSpex.Plug.Validate
  ...
end
