python3通过套接字发送文件

import socket

def send_file(file_path, host, port):
    # 创建套接字
    sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    
    # 绑定地址和端口
    sock.bind((socket.gethostname(), port))
    
    # 监听连接
    sock.listen(1)
    
    print("等待客户端连接...")
    
    # 接受连接
    client_sock, client_addr = sock.accept()
    print("客户端已连接：", client_addr)
    
    try:
        # 打开文件
        file = open(file_path, 'rb')
        
        # 读取文件内容
        buffer = file.read(1024)
        
        while buffer:
            # 发送文件内容
            client_sock.send(buffer)
            buffer = file.read(1024)
        
        print("文件发送完成！")
    except Exception as e:
        print("发送文件时出错：", str(e))
    finally:
        # 关闭文件和套接字
        file.close()
        client_sock.close()
        sock.close()

# 调用函数发送文件
send_file("path/to/file.txt", "localhost", 8000)
