+# Тестовое задание для Stilsoft
+
+Сервис для асинхронной обработки ссылок. Написан на tokio+axum+sled.  
+
+Для настройки сервиса используются переменные окружения в файле `.env`. Экспортировать их в терминал не нужно, они считаются автоматически.
+Запуск осуществляется через `cargo run`.
+
+Для отправки HTTP-запросов к сервису можно использовать дополнительную утилиту run.py:
+```
+./run.py list <url1> <url2>
+./run.py upload <url1> <url2>
+./run.py del <url1> <url2>
+```
+
+Схема:
+
+Получение списка сохранённых ссылок:
+```
+Без фильтров:
+GET localhost:8000/url
+
+С фильтром:
+POST localhost:8000/url
+    body: {"urls": [url1, url2]}
+```
+
+Загрузка ссылок:
+```
+POST localhost:8000/url/upload
+    body: {"urls": [url1, url2]}
+```
+
+Удаление сохранённых ссылок:
+```
+Удаление всех ссылок:
+GET localhost:8000/url/delete
+
+Удаление заданных ссылок:
+POST localhost:8000/url
+    body: {"urls": [url1, url2]}
+```
