本系列博文计划： 　　1、剖析基于Python的Web框架Tornado的源码 　　2、为Python开发一个完善的MVC框架　　 　　首先将带着大家一起来剖析基于python编写的Web框架 tornado ，本着易读易懂的目标来写这一系列，寄希让小白也能zeng明白其中的道理，与其说剖析还不如说是白话，因为本系列都会用通俗的语言去描述Web框架中的各个知识点。 一个脚本引发的一场“案例”.... 运行脚本并在浏览器上访问http://127.0.0.1:8080 #!/usr/bin/env python #coding:utf-8 import socket def handle_request(client): buf = client.recv(1024) client.send("HTTP/1.1 200 OK\r\n\r\n") client.send("Hello, Seven") def main(): sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) sock.bind(('localhost',8080)) sock.listen(5) while True: connection, address = sock.accept() handle_request(connection)

What is Facebook's new Tornado framework?

由 点点圈 提交于 2019-12-30 01:54:07
问题 Facebook just open-sourced a framework called Tornado. What is it? What does it help a site do? I believe Facebook uses a LAMP structure. Is it useful for smaller sites which are written under the LAMP stack? 回答1: It looks like it is a web-server optimized for high-concurrency and high-scalability, but made for smaller payloads. It was designed to support 10,000 concurrent users well. The framework is distinct from most mainstream web server frameworks (and certainly most Python frameworks)

I stumbled across someone's posting that mentioned some signed cookie functions from the Tornado framework and it looks like what I need. What I have in mind is storing a user's id in a tamper proof cookie, and maybe using a decorator for the
