http_client.fetch(req,self.handler_response) defhandler_response(self, response): printresponse.code 用法也比较简单,AsyncHTTPClient中的fetch方法,第一个参数其实是一个HTTPRequest实例对象,因此对于一些和http请求有关的参数,例如method和body,可以使用HTTPRequest先构造一个请求,再扔给fetch方法。通常在转发服务的...

而aiohttp则是一个基于asyncio的异步HTTP客户端/服务器框架,支持HTTP和HTTPS协议,并提供了丰富的API来处理请求和响应。 使用示例 以下是一个使用asyncio和aiohttp发送异步HTTP GET请求的示例: python复制代码 import asyncio import aiohttp async def fetch(session, url): async with session.get(url) as response: ...

在python中其他知名的异步io框架还有：Tornado：异步非阻塞IO的Python Web框架，最新版本的异步协程是基于Python内置的asyncio来实现(老版本用装饰器实现异步)Pulsar：Python的事件驱动并发框架Diesel：基于Greenlet的事件I/O框架安装：pip install aiohttp 基本使用如下：import asynciofrom aiohttp import webasync def index...
async def init(loop): app = web.Application()#创建application实例 app.router.add_route('GET','/', index)#注册路径与请求处理程序 app.router.add_route('GET','/hello/{name}',hello)#之所以上面能识别name,就是因为在这里定义的。 srv = await loop.create_server(app._make_handler(),'127.0....
