Python如何实现WEB

这篇文章主要介绍Python如何实现WEB，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！

Python实现WEB测试环境:

服务器配置: 4 x Intel(R) Xeon(R) CPU E5405 @ 2.00GHz， 4G内存, 操作系统: CentOS 5.3 x86_64

nginx前端 + 4 tornado(0.2) web process

tornado: http://www.tornadoweb.org (已被墙)

Python实现WEB测试场景:

http get请求，服务器端直接返回"hello world"

Python实现WEB代码及nginx配置:

main.py:  #!/usr/bin/python  # -*- coding: utf-8 -*-  """web main"""  from tornado.httpserver import HTTPServer  from tornado.ioloop import IOLoop  from tornado.web import RequestHandler, Application, authenticated  #from rockps.auth import AuthHandler  class MainHandler(RequestHandler):  def get(self):  self.write("hello world")  settings = {  }  application = Application([  (r"/", MainHandler),  ], **settings)  if __name__ == "__main__":  http_server = HTTPServer(application)  http_server.listen(8081)  IOLoop.instance().start()  nginx.conf:  user root;  worker_processes 1;  error_log /var/nginx_error.log;  pid /var/run/nginx.pid;  events {  worker_connections 51200;  use epoll;  }  http {  # Enumerate all the Tornado servers here  upstream frontends {  server 127.0.0.1:8081;  server 127.0.0.1:8082;  server 127.0.0.1:8083;  server 127.0.0.1:8084;  }  #include /etc/nginx/mime.types;  default_type application/octet-stream;  access_log /var/log/nginx/access22.log;  keepalive_timeout 65;  proxy_read_timeout 200;  sendfile on;  tcp_nopush on;  tcp_nodelay on;  gzip on;  gzip_min_length 1000;  gzip_proxied any;   gzip_types text/plain text/html text/css text/xml  application/x-javascript application/xml  application/atom+xml text/javascript;  # Only retry if there was a communication error, not a timeout  # on the Tornado server (to avoid propagating "queries of death"  # to all frontends)  proxy_next_upstream error;  server {  listen 8085;  # Allow file uploads  client_max_body_size 50M;  location ^~ /static/ {  root /var/www;  if ($query_string) {  expires max;  }  }  location = /favicon.ico {  rewrite (.*) /static/favicon.ico;  }  location = /robots.txt {  rewrite (.*) /static/robots.txt;  }  location / {  proxy_pass_header Server;  proxy_set_header Host $http_host;  proxy_set_header X-Real-IP $remote_addr;  proxy_set_header X-Scheme $scheme;  proxy_pass http://frontends;  }  }  }
