+# Отчёт по лабораторной работе №3
+
+Выполнила: студентка гр. ИСЭбд-41 Никифорова Татьяна Сергеевна.
+
+## REST API, Gateway и синхронный обмен между микросервисами
+## Создание микросервисов
+
+Использовала команду `dotnet new web -n worker-1` в терминале для создания моего первого микросервиса.
+
+Далее, с помощью команды `dotnet new sln`, создала решение для проекта. Затем использовала команду `dotnet sln worker-1.sln add worker-1.csproj`, чтобы связать созданное решение с проектом.
+
+Повторила те же действия для второго микросервиса, добавила оба проекта в единое решение.
+
+Добавил библиотеку Swagger и OpenAi в проекты и запустил с помощью команды `dotnet run`".
+
+Скриншоты API приложений:
+
+![](picture/sworker-1.png) 
+![](picture/sworker-2.png)
+
+## Реализация синхронного обмена
+
+Реализовала механизм синхронного обмена сообщениями между микросервисами.
+
+```cs
+app.MapGet("/Authors/", async () =>
+{
+    var httpClient = new HttpClient();
+    var secondWorkerResponse = await httpClient.GetStringAsync("http://worker-1:8080/");
+
+    return secondWorkerResponse.ToArray();
+})
+.WithName("GetRequests")
+.WithOpenApi();
+```
+
+## Реализация gateway при помощи nginx
+
+Реализовала шлюз на основе прозрачного прокси-сервера nginx.
+
+```conf
+server {
+    listen       8080;
+    listen  [::]:8080;
+    server_name  localhost;
+
+    location / {
+        root   /usr/share/nginx/html;
+        index  index.html index.htm;
+    }
+
+    location /worker-1/ {
+        proxy_pass       http://worker-1:8080/;
+        proxy_set_header Host      $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        proxy_set_header X-Forwarded-Prefix /worker-1;
+    }
+
+    location /worker-2/ {
+        proxy_pass       http://worker-2:8080/;
+        proxy_set_header Host      $host;

+        proxy_set_header X-Forwarded-Proto $scheme;
+        proxy_set_header X-Forwarded-Prefix /worker-2;
+    }
+}
+
+```
+
+Результаты, после вызова команды `docker-compose up`:
