# Отчет по лабораторной работе №4
|
||||
|
||||
Выполнил студентка гр. ИСЭбд-41 Юденичева Дарья
|
||||
|
||||
## Tutorial
|
||||
|
||||
Установила rabbitMQ server, erlang и зашла в брокер под гостем по http://localhost:15672/#/
|
||||
|
||||
|
||||
|
||||
Туториал-1:

## Разработка демонстрационных приложений
|
||||
|
||||
Предметная область: Расходные договора и договора на платное обучение.
|
||||
Разработа три приложения согласно предметной области.
|
||||
|
||||
1. Publisher
|
||||
|
||||
```py
|
||||
import pika
|
||||
import time
|
||||
import random
|
||||
|
||||
collection = ["Application for general business expenses", "The contract is completed", "Enrollment order completed", "Student enrolled"]
|
||||
|
||||
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()
|
||||
```
