JoKeRooo7 / redis.py

The redis python project. And the automatic launch of scripts using yml

Working with Redis in python

• Installation and launch of Redis
• Configuration settings
• Produser
• Consumer

Installing the Redis server and running it

• macOS
  • installing brew install redis
  • launching the redis-server

Configuring the configuration

I created a separate file with the initial Redis settings - server_data.py .

• REDIS_HOST - the address where REDIS is running
• REDIS_PORT - the port through which REDIS is running * QUEUE_NAME - the name of the queue in REDIS
• SUBSCRIBE - subscription channel where messages will be sent

Produser (manufacturer)

Represented by a file produser.py .

The encoding format in the file is `utf-8'.

# -*- coding: utf-8 -*-

The main() function creates a redis_info host object.

It also has an infinite loop for generating messages in the json format. The generate_json_message() function is used for json. It generates a dictionary with data. The function returns a formatted string in json format from the message dictionary.

I add the generated json file to the top of the queue using the lpush method to the SUBSCRIBE subscription channel.

Information is output to the terminal using the logger object.

Generation occurs once every 1 second time.sleep(1)

Consumer

File consumer.py . To run it, you need command-line arguments, numbers, and if they meet on the server, it will swap them out. (This is done so that if money is sent to a bad account (account number), it can be deployed back)

The find_accounts(bad_accounts) function accepts comma-separated numbers of bad accounts.

It reads all transactions from the beginning to the end. reverse() - expands messages so that there are messages previously sent at the beginning. Messages are being read in the loop, and if there is a number from bad_accounts, it expands the numbers and outputs them to the terminal.
