安装aiomysql模块
pip3 install aiomysql
示例1:
import asyncio import aiomysql async def execute(): # 网络IO操作:连接MySQL conn = await aiomysql.connect(host='127.0.0.1', port=3306, user='root', password='123', db='mysql', ) # 网络IO操作:创建CURSOR cur = await conn.cursor() # 网络IO操作:执行SQL await cur.execute("SELECT Host,User FROM user") # 网络IO操作:获取SQL结果 result = await cur.fetchall() print(result) # 网络IO操作:关闭链接 await cur.close() conn.close() asyncio.run(execute())
示例2:
#!/usr/bin/env python # -*- coding:utf-8 -*- import asyncio import aiomysql async def execute(host, password): print("开始", host) # 网络IO操作:先去连接 47.93.40.197,遇到IO则自动切换任务,去连接47.93.40.198:6379 conn = await aiomysql.connect(host=host, port=3306, user='root', password=password, db='mysql') # 网络IO操作:遇到IO会自动切换任务 cur = await conn.cursor() # 网络IO操作:遇到IO会自动切换任务 await cur.execute("SELECT Host,User FROM user") # 网络IO操作:遇到IO会自动切换任务 result = await cur.fetchall() print(result) # 网络IO操作:遇到IO会自动切换任务 await cur.close() conn.close() print("结束", host) task_list = [ execute('47.93.41.197', "root!2345"), execute('47.93.40.197', "root!2345") ] asyncio.run(asyncio.wait(task_list))
