+# Отчет по лабораторной работе №3
+
+Выполнил студент  Михайлов Юрий гр. ИСЭбд-41 .
+
+## REST API, Gateway и синхронный обмен между микросервисами
+
+## Создание микросервисов
+
+1. С помощью команды `dotnet new web -n worker-1` в терминале создали первый микросервис.
+2. Добавил решение `dotnet new sln`. Связал решение и проект командой `dotnet sln worker-1.sln add worker-1.csproj` повторил для 2-ого микросервиса.
+3. Добавил библиотеку Swagger и OpenAi в проекты и запустил с помощью команды `dotnet run`.
+
+Протестированный микросервис:
+![](picture/1.png) 
+
+
+## Реализация синхронного обмена.
+Реализован код, который вызывет сихронно данные из соседнего микросервиса.
+
+```cs
+app.MapGet("/Сities/", async () =>
+{
+    var httpClient = new HttpClient();
+    var secondWorkerResponse = await httpClient.GetStringAsync("http://worker-1:8080/");
+    return secondWorkerResponse.ToArray();
+})
+.WithName("GetCountries")
+.WithOpenApi();
+```
+
+## Реализация gateway при помощи nginx
+
+Добавил nginx.conf:
+
+```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;
+    }
+}
+```
+Результат после команды `docker-compose up`:
