初始tornado框架
2.7版本的一个简单的框架
1 from wsgiref.simple_server import make_server 2 3 def new(): 4 return 'new' 5 def index(): 6 return 'index' 7 8 urls={'/new':new, 9 '/index':index 10 } 11 12 def Runserver(environ,start_response): 13 start_response('200 OK',[('Content-Type','text/html')]) 14 url=environ['PATH_INFO'] 15 if url in urls.keys(): 16 ret=urls[url]() 17 else: 18 ret='404' 19 return ret 20 21 if __name__=="__main__": 22 httpd=make_server('',8000,Runserver) 23 httpd.serve_forever()
一个简单的tornado脚本
