    项目结构

    创建对应的文件夹并测试一个最简单的功能

    main.py

     1 #!/usr/bin/env python
     2 # coding:utf-8
     3 
     4 import tornado.ioloop
     5 import tornado.options

     7 import tornado.web
     8 from tornado.options import define, options
     9 
    10 from url import url
    11 from application import settings
    12 
    13 define("port", default="7777", help="run on the given port", type=int)
    14 
    15 
    16 class Application(tornado.web.Application):
    17 
    18     def __init__(self):
    19         tornado.web.Application.__init__(self, url, **settings)
    20 
    21 if __name__ == '__main__':
    22     tornado.options.parse_command_line()
    23     http_server = tornado.httpserver.HTTPServer(Application())
    24     http_server.listen(options.port)
    25     tornado.ioloop.IOLoop.instance().start()

    7 url = [(r"^/(favicon.ico)", tornado.web.StaticFileHandler,
    8          dict(path=application.settings['static_path']))]
    9 url += [(r"^/", "handlers.index.IndexHandler")]

    application.py

     5 import os

     9 # import base64
    10 # import uuid
    11 # print base64.b64encode(uuid.uuid4().bytes+uuid.uuid4().bytes)

    13 settings = dict(
    14     template_path=os.path.join(os.path.dirname(__file__), "templates"),
    15     static_path=os.path.join(os.path.dirname(__file__), "static"),
    16     xsrf_cookies=True,
    17     cookie_secret="RYxFqFQyRCiCZ/nxFfTMCrbqZpRZ5UW9tQ86fKvrfIw=",
    18     login_url="/login",
    19     debug=True,
    20 )
    View Code

    index.py

     1 #!/usr/bin/env python
     2 #-*- coding:utf-8 -*-
     3 
     4 import tornado.web
     5 
     6 
     7 class IndexHandler(tornado.web.RequestHandler):
     8 
     9     '''
    10     主页处理类
    11     '''
    12 
    13     def get(self):
    14         self.write("Index")
    View Code

    favicon.ico选择自己喜欢的ico放置于static目录下

    这样,最简单的一个Web服务就完成了,Ctrl+B运行main.py

    在浏览器输入localhost:7777,看到返回的Index字符串则表示运行正常。

    更改说明:git仓库的默认端口为8909   -->在浏览器输入localhost:8909,看到返回的Index字符串则表示运行正常。
