观察到context.set_ciphers那行,思考:aiohttp的ClientSession中发起请求的方法都有个ssl参数,从typing可知他们接受的参数正是SSLContext emmm,有戏 那把ssl参数换成自己的就ok了吗?好像没这么简单。还得书写轮换ssl指纹的逻辑,如下 importrandom i...
from aiohttp import ClientSession import asyncio async def get_html(url: str): async with ClientSession() as session: #client与server建立会话 async with session.get(url) as res: #response print(res.status) print(await res.text())
通过session.get()方法发起请求,并使用response.text()获取响应内容。最后,在main函数中,我们创建了一个ClientSession实例,并调用了fetch函数来执行实际的网络请求。整个过程简洁明了,充分体现了 aiohttp 在处理 HTTP 请求时的高效与便捷。 通过这样一个简单的示例,我们不仅学会了如何使用 aiohttp 发起 HTTP 请求,还...

http 请求可以直接用aiohttp.ClientSession().request(method,url,**kwargs),http 也是一个协程,可以保证网络请求时不被阻塞,通过await http()便可以拿到接口测试数据 async def http(domain, *args, **kwargs): """ http请求处理器 :param domain: 服务地址 ...
