Function plugs are similar to module plugs, but they are contained in a function instead of a module. This means that we don't have to call the init to arrange the options. However, function plugs receive two arguments, exactly like the call function in module plugs: the connection and the options. The following function is a function plug:
def my_function_plug(conn, _options) do conn |> put_resp_content_type("text/plain") |> send_resp(200, "Hello #{conn.assigns.username}")end
In this function, we take the connection and pass it through to put_resp_content_type, which will modify the connection to set the content type of the response. Then, we take this modified connection to send a response, setting 200 as the status ...
