Я хочу объединить API погоды с формой, в которой вы вводите свое настроение, в 1 приложение: форму, в которой вы заполняете свой город (чтобы вы знали погоду) и где вы заполняли свое настроение в тот день.
В моем сервере. js файл У меня есть две функции GET и две функции POST. Тем не менее, я думаю, что могу использовать res.render ('index', ...) только один раз. Как объединить две функции GET в одну рабочую функцию?
