当然，我可以为你写一个复杂的代码示例。下面是一个使用Python编写的复杂代码示例，它实现了一个简单的Web服务器，并支持基本的HTTP请求处理和路由功能。 ```python import socket import threading from urllib.parse import urlparse, parse_qs class HTTPServer: def __init__(self, host='127.0.0.1', port=8080): self.host = host self.port = port self.routes = {} def route(self, path): def decorator(func): self.routes[path] = func return func return decorator def start(self): with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as server_socket: server_socket.bind((self.host, self.port)) server_socket.listen(5) print(f"Server started at http://{self.host}:{self.port}") while True: client_socket, client_address = server_socket.accept() threading.Thread(target=self.handle_request, args=(client_socket,)).start() def handle_request(self, client_socket): request = client_socket.recv(1024).decode('utf-8') if not request: client_socket.close() return request_line = request.splitlines()[0] method, path, version = request_line.split() url = urlparse(path) params = parse_qs(url.query) response = self.dispatch(method, url.path, params) client_socket.sendall(response) client_socket.close() def dispatch(self, method, path, params): if path in self.routes: handler = self.routes[path] response = handler(params) else: response = self.not_found() return response def not_found(self): return b"HTTP/1.1 404 Not Found\r\nContent-Type: text/plain\r\n\r\n404 Not Found" # Create an instance of the server server = HTTPServer() # Define routes and their corresponding handler functions @server.route('/') def home(params): return b"HTTP/1.1 200 OK\r\nContent-Type: text/html\r\n\r\n

Welcome to the Home Page

" @server.route('/hello') def hello(params): name = params.get('name', ['World'])[0] return f"HTTP/1.1 200 OK\r\nContent-Type: text/html\r\n\r\n

Hello, {name}!

".encode('utf-8') # Start the server if __name__ == "__main__": server.start() ``` 这个代码实现了一个简单的Web服务器，具有以下功能： 1. 监听指定的主机和端口（默认是`127.0.0.1:8080`）。 2. 支持基本的HTTP请求处理。 3. 支持简单的路由机制，通过装饰器定义路径和对应的处理函数。 4. 能够解析URL中的查询参数。 5. 返回简单的HTML响应。 你可以运行这个代码，然后在浏览器中访问`http://127.0.0.1:8080/`和`http://127.0.0.1:8080/hello?name=YourName`来查看效果。
