在django项目中再开启一个socket服务

1.任意项目任意地方写一个createSocket.py文件(文件名任意)

import socket
from django.conf import settings

sock = socket.socket()

def startSocket():
    ip = settings.LOCALHOSTIP
    port = settings.LOCALHOSTPORT
    sock.bind((ip, port))
    sock.listen(10)
    while True:
        try:
            conn, ip = sock.accept()
            res = conn.recv(1024)
            print(res)
        except:
            continue

2.在manage.py中开启进程，运行socket

#!/usr/bin/env python
"""Django's command-line utility for administrative tasks."""
import os
import sys
from multiprocessing import Process
from smartlabdemo.socketserver.createSocket import startSocket


def main():
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'smartlabdemo.settings.dev')
    try:
        from django.core.management import execute_from_command_line
    except ImportError as exc:
        raise ImportError(
            "Couldn't import Django. Are you sure it's installed and "
            "available on your PYTHONPATH environment variable? Did you "
            "forget to activate a virtual environment?"
        ) from exc
        
    # 开启进行监听硬件
    '''
        django项目中再开启一个socket会报错，原因是python一个进程下只能有一个socket服务
    '''
    socketProcess = Process(target=startSocket)
    # 启动进程
    socketProcess.start()
    
    
    execute_from_command_line(sys.argv)


if __name__ == '__main__':
    main()

3.测试，写一个模拟客户端clientdemo.py

import socket

data = 'AA 55 00 00 00 90 00 01 00 00 00 00 00 01 30 30 2D 30 30 2D 30 30 2D 30 30 2D 30 30 2D 30 30 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 55 5F 4C 61 6D 70 73 68 61 64 65 5F 4C 32 35 34 00 00 00 00 72 65 70 6F 72 74 50 6F 77 65 72 44 61 74 61 00 00 00 00 00 00 00 00 3C 32 32 38 2E 30 33 56 00 00 00 30 2E 30 30 30 41 00 00 00 00 30 2E 30 30 57 00 00 00 00 00 30 2E 30 30 33 6B 57 2A 68 00 00 00 00 00 00 30 64 30 30 68 30 31 6D 35 36 73 00 00 00 00 38 0F '

client = socket.socket()
ip = '192.168.50.227'
port = 8100
client.connect((ip, port))
client.send(data.encode('utf8'))
print('发送成功')

4.结果

成功！！！！！！！！！！！！！
