python的httpx包实现异步

import asyncio

from httpx import AsyncClient

#声明该方法为异步方法对象
async def printNum(num):
	$ 异步版的with as
    async with AsyncClient() as client:
    	# 等待函数完成
        req = await client.get(url="")
        $ 输出结果的text
        print(req.text)


if __name__ == '__main__':
	# 用num作为变量遍历range(10)的结果，每次遍历都调用printNum方法
    tasks = [printNum(num) for num in range(10)]
    # 新建一个异步loop
    loop = asyncio.get_event_loop()
    # 等待异步程序完成
    loop.run_until_complete(asyncio.wait(tasks))
    # 关闭loop
    loop.close()
