path(token)
Stores the request path on the token on the key :path
iex> request = %Aino.Request{path: ["orders", "10"]}
iex> token = %{request: request}
iex> token = Middleware.path(token)
iex> token.path
["orders", "10"]query_params(token)
Stores query parameters on the token
Converts map and stores on the key :query_params
iex> request = %Aino.Request{args: [{"key", "value"}]}
iex> token = %{request: request}
iex> token = Middleware.query_params(token)
iex> token.query_params
%{"key" => "value"}request_body(token)
