本文针对 python 2.7 版本，介绍了 BaseHTTPServer 这个库的使用方法。
这个库是 python 自带的标准库的一部分，不需要额外安装，在 linux 系统下，位置在 /usr/lib/python2.7/BaseHTTPServer.py。

这个类可以帮助你快速编写一个 HTTP 服务端 server。别说了，先上代码：
fromBaseHTTPServerimportBaseHTTPRequestHandler
importcgi
importjson
classTodoHandler(BaseHTTPRequestHandler):
"""A simple TODO server
which can display and manage todos for you.
"""
# Global instance to store todos. You should use a database in reality.
TODOS=
defdo_GET(self):
# return all todos
ifself.path!='/':
self.send_error(404"File not found.")
return
# Just dump data to json, and return it
message=json.dumps(self.TODOS)
self.send_response(200)
self.send_header('Content-type''application/json')
self.end_headers
self.wfile.write(message)
defdo_POST(self):
"""Add a new todo
Only json data is supported, otherwise send a 415 response back.
Append new todo to class variable, and it will be displayed
in following get request
"""
ctypepdict=cgi.parse_header(self.headers['content-type'])ifctype=='application/json':
length=int(self.headers['content-length'])post_values=json.loads(self.rfile.read(length))
self.TODOS.append(post_values)
else:
self.send_error(415"Only json data is supported.")
self.wfile.write(post_values)
if__name__=='__main__':
# Start a simple server, and loop forever
fromBaseHTTPServerimportHTTPServer
server=HTTPServer(('localhost'8888),TodoHandler)
print("Starting server, use <Ctrl-C> to stop")
server.serve_forever
这段代码实现的功能很简单，就是一个简单的 Todo 管理：你可以添加 todo，也可以查询 todo。更新和删除 todo 可以根据上面的代码自行添加。
