Python3:如何关闭http.server打开的连接？

from http.server import BaseHTTPRequestHandler, HTTPServer

class MyHTTPRequestHandler(BaseHTTPRequestHandler):
    def do_GET(self):
        # 处理GET请求的逻辑
        pass

# 创建HTTPServer实例对象，并指定自定义的请求处理类
server = HTTPServer(('localhost', 8000), MyHTTPRequestHandler)

# 关闭服务器
server.shutdown()

from http.server import BaseHTTPRequestHandler, HTTPServer

class MyHTTPRequestHandler(BaseHTTPRequestHandler):
    def do_GET(self):
        # 处理GET请求的逻辑
        pass

# 创建HTTPServer实例对象，并指定自定义的请求处理类
server = HTTPServer(('localhost', 8000), MyHTTPRequestHandler)

try:
    # 启动服务器
    server.serve_forever()
except KeyboardInterrupt:
    # 捕获Ctrl+C键盘中断信号，关闭服务器
    server.shutdown()
