aiohttp github.com/aio-libs/aio asyncio + HTTP。它将asyncio的异步编程和HTTP网络请求相结合,实现了异步非阻塞的HTTP client/server。利用asyncio避免同步网络IO的阻塞,可以处理大量网络请求。性能高,但需要会asyncio编码 vs requests:异步请求 异步网络服务 性能高,非阻塞 依赖asyncio aiomultiprocess github.com/omni...
异步HTTP客户端和服务器,为asyncio 设计。 因为 作为客户端的 requests 支持同步请求模式, 一个请求完成后,才能执行下一个请求。 Asynchronous HTTP Client/Server forasyncioand Python. Key Features¶ Supports bothClientandHTTP Server. Supports bothServer WebSocketsandClient WebSocketsout-of-the-box without ...
Python 的例子是 Echo Client,我们稍微复杂一点,是 HTTP Client,都是 TCP。 class ClientProtocol(asyncio.Protocol): def __init__(self, loop): self.loop = loop def connection_made(self, transport): request = 'GET / HTTP/1.1\r\nHost: localhost\r\n\r\n' ...

要使用Python的asyncio和aiohttp库实现异步HTTP请求,首先需要安装aiohttp库,可以使用pip进行安装: pip install aiohttp 接下来,你可以编写一个简单的异步HTTP请求示例: import asyncio import aiohttp async def fetch(session, url): async with session.get(url) as response: ...
