Написать сервис на Golang, который принимает массив URL-ов товаров https://www.amazon.co.uk, для данных URL он должен загрузить наименование, цена, фото товара(только URL, грузить изображение не надо), пример:
[ { "url": "https://www.amazon.co.uk/gp/product/1509836071", "meta": { "title": "The Fat-Loss Plan: 100 Quick and Easy Recipes with Workouts", "price": "8.49", "image": "https://images-na.ssl-images-amazon.com/images/I/51kB2nKZ47L.SX382_BO1,204,203,200.jpg", } }, ... ]
Сервис необходимо завернуть в Docker. В Docker можно сделать опционально. Загрузчик должен иметь конфигурируемое ограничение на количество одновременных запросов в amazon.
