Python实现HTTP请求中的连接复用 在HTTP通信中,连接复用(Connection Reuse)是一个重要的概念,它允许客户端和服务器在同一个TCP连接上发送和接收多个HTTP请求/响应,而不是为每个新的请求/响应都创建一个新的连接。这种技术可以显著提高网络性能,减少网络延迟和资源消耗。在Python中,我们可以使用多种方法来实现HTTP请求的...

而requests模块给出了实现的办法——requests.Session()。 requests.Session(),复用TCP 参考官方的说明。 Keep-AliveExcellent news — thanks to urllib3, keep-alive is 100% automatic within a session! Any requests that you make within a session will automatically reuse the appropriate connection!Note ...
并行: 并行是指多个任务同时执行,比如两个男人同时在给自己女朋友发微信。 并发: 并发是多个任务交替轮流使用资源,比如一个男人在给他7个女朋友发微信,只要他发的够快,宏观上来说他在同时聊7个人。 进程状态与调度 在了解其他概念之前,我们首先要了解进程的几个状态。在程序运行的过程中,由于被操作系统的调度算法...

Even though the Requests library is a common staple for many Python developers, it’s not included in Python’s standard library. There are good reasons for that decision, primarily that the library can continue to evolve more freely as a self-standing project. Note: Requests doesn’t support...

用Python 写过爬虫的同学,一定听说或使用过requests库,以下是使用requests访问Hello World服务端程序的示例代码: 1 2 3 4 5 6 7 8 9 10 # demo_requests.py importrequests response = requests.request('GET','http://127.0.0.1:8000/') print(response.status_code)# 响应状态码 ...
