Python中aiohttp模块的简单运用方式

pip install aiohttp

import aiohttp  # 导入异步 HTTP 请求库 aiohttp
import asyncio  # 导入异步编程库 asyncio

async def fetch(session, url):
    async with session.get(url) as response:  # 使用 session 对象发出 GET 请求
        return await response.text()  # 返回响应文本

async def main():
    async with aiohttp.ClientSession() as session:  # 创建异步 HTTP 会话
        html = await fetch(session, '<https://www.example.com>')  # 调用 fetch 函数获取 HTML 内容
        print(html)  # 打印 HTML 内容

asyncio.run(main())  # 异步运行主函数

import aiohttp
import asyncio
import json

async def main():
    async with aiohttp.ClientSession() as session:
        # 发送get请求
        async with session.get('<https://www.example.com>') as resp:
            print(await resp.text())

        # 发送post请求
        async with session.post('<https://www.example.com>', json={'key': 'value'}) as resp:
            print(await resp.text())

        # 发送put请求
        async with session.put('<https://www.example.com>', json={'key': 'value'}) as resp:
            print(await resp.text())

        # 发送delete请求
        async with session.delete('<https://www.example.com>', json={'key': 'value'}) as resp:
            print(await resp.text())

asyncio.run(main())
