+# Отчет по лабораторной работе №3
+
+Выполнила студентка гр. ИСЭбд-41 Островская С. Ф.
+
+## REST API, Gateway и синхронный обмен между микросервисами
+
+## Создание микросервисов
+
+1. Создала первый микросервис - `dotnet new web -n worker-1`
+2. Добавила решение - `dotnet new sln`
+3. Связала решение и проект - `dotnet sln worker-1.sln add worker-1.csproj`
+4. Для второго микросервиса выполнила пункты 1-3
+5. Добавила библиотеку Swagger и OpenAi - `dotnet add worker-1.csproj package Swashbuckle.AspNetCore` , `dotnet add worker-1.csproj package Microsoft.AspNetCore.OpenApi`
+6. Запустила - `dotnet run`
+
+Скриншоты протестированных микросервисов:
+![](pic/pic1.jpg)
+![](pic/pic2.jpg)
+
+## Реализация синхронного обмена
+
+Код реализации синхронного обмена:
+
+```cs
+//Файд Program.cs проекта worker-2
+app.MapGet("/Requests/", 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
+
+Добавила 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-Real-IP $remote_addr;
+ proxy_set_header X-Forwarded-Proto $scheme;
+ proxy_set_header X-Forwarded-Prefix /worker-2;
+ }
+}
+
+```
+
+Результат, после выполнения команды `docker compose up`:
+
+Docker:
