python套接字发送文件函数说明

import socket

def send_file(file_path, host, port):
    # 创建套接字对象
    sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    
    try:
        # 连接到远程主机
        sock.connect((host, port))
        
        # 打开文件并读取内容
        with open(file_path, 'rb') as file:
            file_data = file.read()
        
        # 发送文件内容到远程主机
        sock.sendall(file_data)
        
        print("文件发送成功！")
        
    except Exception as e:
        print("文件发送失败：", str(e))
        
    finally:
        # 关闭套接字和文件
        sock.close()

# 调用函数发送文件
send_file("/path/to/file.txt", "remote_host", 1234)
