要使用Python实现支持文件传输的TCP客户端与服务器通信，可以按照以下思路编写代码。 #### 服务器端代码示例 ```python import socket # 创建TCP/IP套接字 server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) # 绑定地址和端口 server_address = ('localhost', 8888) server_socket.bind(server_address) # 监听连接 server_socket.listen(1) print('Waiting for a connection...') connection, client_address = server_socket.accept() try: print(f'Connection from {client_address}') # 接收文件名 file_name = connection.recv(1024).decode() print(f'Receiving file: {file_name}') # 接收文件内容 with open(file_name, 'wb') as file: while True: data = connection.recv(1024) if not data: break file.write(data) print('File received successfully.') finally: # 关闭连接 connection.close() server_socket.close() ``` #### 客户端代码示例 ```python import socket # 创建TCP/IP套接字 client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) # 服务器地址和端口 server_address = ('localhost', 8888) client_socket.connect(server_address) # 要发送的文件名 file_name = 'test.txt' client_socket.send(file_name.encode()) # 发送文件内容 with open(file_name, 'rb') as file: while True: data = file.read(1024) if not data: break client_socket.send(data) # 关闭连接 client_socket.close() ``` 上述代码中，服务器端首先创建一个TCP套接字，绑定地址和端口并开始监听连接。当客户端连接后，服务器接收客户端发送的文件名，然后接收文件内容并保存到本地。客户端则创建一个TCP套接字，连接到服务器，发送文件名和文件内容。
