+# Отчет по лабораторной работе №3
+
+Выполнил студент гр. ИСЭбд-41 Мельников К.Ю.
+
+## REST API, Gateway и синхронный обмен между микросервисами
+
+## Создание микросервисов
+
+1. С помощью команды `dotnet new web -n worker-1` в терминале создал первый микросервис
+2. Добавил решение командой  `dotnet new sln`
+3. Связал решение и проект командой `dotnet sln worker-1.sln add worker-1.csproj`
+4. Повторил действие для второго микросервиса
+5. Добавил библиотеку Swagger и OpenAi в проекты и запустил с помощью команды `dotnet run`
+
+Скриншоты протестированных микросервисов:
+![](scrins/1.png) 
+
+
+## Реализация синхронного обмена
+
+Реализовал код, который вызывает сихронно данные из соседнего микросервиса.
+
+```cs
+//worker-2
+app.MapGet("/Parts/", async () =>
+{
+    var httpClient = new HttpClient();
+    var secondWorkerResponse = await httpClient.GetStringAsync("http://worker-1:8080/");
+
+    return secondWorkerResponse.ToArray();
+})
+.WithName("GetCars")
+.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-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`:

-## Разработка демонстрационных приложений
-
-Предметная область: Дополенительные соглашения и договора на заселение в отель Туристического агентства.
-Разработа три приложения согласно предметной области.
-
-1. Publisher
-
-```py
-import pika
-import time
-import random
-
-collection = ["Application for Travel Agency", "Buying tickets", "Execution of the agreement", "Check-into a hotel"]
-
-connection = pika.BlockingConnection(pika.ConnectionParameters('localhost'))
-channel = connection.channel()
-
-channel.exchange_declare(exchange='Agreements', exchange_type='fanout')
-
-while True:
-    message = f"Message: {random.choice(collection)}"
-
-    channel.basic_publish(exchange='Agreements', routing_key='', body=message)
-
-    time.sleep(1)
-
-connection.close()
-```
-
-2. Consumer 1.
-
-```py
-import pika
-import time
-
-def process_message(ch, method, properties, body):
-    print(f"Получено сообщение: {body}")
-    time.sleep(3)
-    print("Сообщение успешно обработано")
-
-connection = pika.BlockingConnection(pika.ConnectionParameters('localhost'))
-channel = connection.channel()
-
-result = channel.queue_declare(queue='', exclusive=True)
-queue_name = result.method.queue
-
-channel.queue_bind(exchange='Agreements', queue=queue_name)
-
-channel.basic_consume(queue=queue_name, on_message_callback=process_message, auto_ack=True)
-
-print('Ожидание сообщений...')
-channel.start_consuming()
-```
-
-3. Consumer 2.
-
-```py
-import pika
-
-
-def process_message(ch, method, properties, body):
-    print(f"Получено сообщение: {body}")
-    print("Сообщение успешно обработано")
-
-connection = pika.BlockingConnection(pika.ConnectionParameters('localhost'))
-channel = connection.channel()
-
-result = channel.queue_declare(queue='', exclusive=True)
-queue_name = result.method.queue
-
-channel.queue_bind(exchange='Agreements', queue=queue_name)
-
-channel.basic_consume(queue=queue_name, on_message_callback=process_message, auto_ack=True)
-
-print('Ожидание сообщений...')
-channel.start_consuming()
-```
-
-## Результаты выполнения лабораторной работы
-
-Результат отработки Consumer_1:
-
-![](scrins/maintask1.png)
-
-Результат отработки Consumer_2:
-
-![](scrins/maintask2.png)
-
-![](scrins/maintask_dop.png)
-
-Вывод: Consumer_2 нагружает меньше памяти, чем Consumer_1 и принимает сообщения гораздо быстрее, тем самым не позволяя очереди накапливать огромное количество сообщений.
