下面这段代码可以参考http://www.tornadoweb.org/en/stable/，这个是tornado宽框架
import tornado.ioloop
import tornado.web
class MainHandler(tornado.web.RequestHandler):
def get(self):
print('get111')
u = self.get_argument('user')
p = self.get_argument('pwd')
if u == 'lws' and p =='lws123':
self.write("welcome")
else:
self.write('滚')
def post(self):
u = self.get_argument('user')
p = self.get_argument('pwd')
print(u,p)
self.write("POST")
def make_app():
return tornado.web.Application([
(r"/", MainHandler),
])
if __name__ == "__main__":
app = make_app()
app.listen(8888)
tornado.ioloop.IOLoop.current().start()
