+# Отчет по лабораторной работе №4
+
+Выполнил студент гр. ИСЭбд-41 Андрианов Е.П.
+
+## Прохождение tutorial
+
+Установил rabbitMQ server, erlang и зашел в брокер под гостем по http://localhost:15672/#/

+Туториал 3:

+![](pic/3.1.png)
+
+## Разработка демонстрационных приложений
+
+Предметная область: Доставка почты. Производитель - почтовая станция, которая сигнализирует о том, что пришла почта. Потребитель 1 - курьер тратит время и доставляет почту. Потребитель 2 - мы отправляет письмо по почте.
+
+1. Publisher
+
+```py
+using System.Text;
+using RabbitMQ.Client;
+
+Random rand = new Random();
+var factory = new ConnectionFactory { HostName = "localhost" };
+using var connection = factory.CreateConnection();
+using var channel = connection.CreateModel();
+
+channel.ExchangeDeclare(exchange: "post", type: ExchangeType.Fanout);
+
+foreach (var item in Enumerable.Range(0, 1000))
+{
+ var message = rand.Next().ToString();
+
+ var body = Encoding.UTF8.GetBytes(message);
+ channel.BasicPublish(exchange: "post",
+ routingKey: string.Empty,
+ basicProperties: null,
+ body: body);
+
+ Console.WriteLine($" [x] Письмо готово {message}");
+ await Task.Delay(500);
+}
+
+Console.WriteLine(" Нажми [enter] чтобы выйти.");
+Console.ReadLine();
+
+static string GetMessage(string[] args)
+{
+ return ((args.Length > 0) ? string.Join(" ", args) : "info: Привет Мир!");
+}
+```
+
+2. Consumer 1.
+
+```py
+using System.Text;
+using RabbitMQ.Client;
+using RabbitMQ.Client.Events;
+
+Random rand = new Random();
+var factory = new ConnectionFactory { HostName = "localhost" };
+using var connection = factory.CreateConnection();
+using var channel = connection.CreateModel();
+
+string queueName = $"courier{rand.Next()}";
+
+channel.QueueDeclare(queue: queueName);
+channel.QueueBind(queue: queueName,
+ exchange: "post",
+ routingKey: string.Empty);
+
+Console.WriteLine(" [*] Ожидание сообщения.");
+
+var consumer = new EventingBasicConsumer(channel);
+consumer.Received += async (model, ea) =>
+{
+ byte[] body = ea.Body.ToArray();
+ var message = Encoding.UTF8.GetString(body);
+
+ int waitTime = rand.Next(20, 90);
+ Thread.Sleep(waitTime * 100);
+
+ string outputText = $"Курьер с письмом потратил {waitTime} минут и доставил письмо {message}";
+ Console.WriteLine($" [x] Сделано. {outputText}");
+ channel.BasicAck(deliveryTag: ea.DeliveryTag, multiple: false);
+};
+channel.BasicConsume(queue: queueName,
+ autoAck: false,
+ consumer: consumer);
+
+Console.WriteLine(" Нажми [enter] чтобы выйти.");
+Console.ReadLine();
+
+```
+
+3. Consumer 2.
+
+```py
+using System.Text;
+using RabbitMQ.Client;
+using RabbitMQ.Client.Events;
+
+var factory = new ConnectionFactory { HostName = "localhost" };
+using var connection = factory.CreateConnection();
+using var channel = connection.CreateModel();
+
+channel.QueueDeclare(queue: "mail");
+channel.QueueBind(queue: "mail",
+ exchange: "post",
+ routingKey: string.Empty);
+
+Console.WriteLine(" [*] Ожидание сообщения.");
+
+var consumer = new EventingBasicConsumer(channel);
+consumer.Received += async (model, ea) =>
+{
+ byte[] body = ea.Body.ToArray();
+ var message = Encoding.UTF8.GetString(body);
+
+ string outputText = $"Письмо было отправлено почтой {message}";
+ Console.WriteLine($" [x] Сделано. {outputText}");
+ channel.BasicAck(deliveryTag: ea.DeliveryTag, multiple: false);
+};
+channel.BasicConsume(queue: "mail",
+ autoAck: false,
+ consumer: consumer);
+
+Console.WriteLine(" Нажми [enter] чтобы выйти.");
+Console.ReadLine();
+```
+
+## Результаты выполнения лабораторной работы
+Вот работа наших 2 потребителей и производителя
+![](pic/4.1.png)
+Наш график, где нагляжно видно очереди и скорость прохода сообщений
+![](pic/4.png)
+Очередь с названием "courier..." - это наша очередь с курьером, а очередь "mail" - почтой
+![](pic/4.2.png)
+Вывод: Consumer2 - меньше нагружает память(из-за отсутствия простаивания очереди) и быстрее по времени, чем Consumer1(Реально, я вот щас пишу записку, а он до сих пор назначает курьеров😂)
