使用Paramiko处理中断的下载

import paramiko

def download_file(hostname, username, password, remote_path, local_path):
    try:
        # 建立SSH连接
        ssh = paramiko.SSHClient()
        ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
        ssh.connect(hostname, username=username, password=password)
        
        # 创建SFTP客户端对象
        sftp = ssh.open_sftp()
        
        # 下载文件
        sftp.get(remote_path, local_path)
        
        # 关闭连接
        sftp.close()
        ssh.close()
        
        print("文件下载成功！")
    except paramiko.AuthenticationException:
        print("认证失败，请检查用户名和密码！")
    except paramiko.SSHException as e:
        print("SSH连接错误：", str(e))
    except paramiko.SFTPException as e:
        print("SFTP操作错误：", str(e))
    except Exception as e:
        print("未知错误：", str(e))

# 调用函数进行下载
download_file("服务器IP地址", "用户名", "密码", "远程文件路径", "本地文件路径")
