用socket写一个简单的服务器

import socket

sk=socket.socket()

sk.bind(("127.0.0.1",7001))

sk.listen()

def login(url):
    with open('login.html','rb') as f:
        return f.read()
def index(url):
    with open('index1.html','rb') as f:
        return f.read()

def mng(url):
    with open('bootstrap/dist/js/bootstrap.js', 'rb') as f:
        return f.read()
def css(url):
    with open('bootstrap/dist/css/bootstrap.css', 'rb') as f:
        return  f.read()
def js(url):
    with open('jquery-3.2.1.min.js', 'rb') as f:
        return  f.read()
li=[
    ('/login/', login),
    ('/index/', index),
    ('/jquery-3.2.1.min.js/', js),
    ('/bootstrap.css/', css),
    ('/bootstrap.js/', mng),
