Python Paramiko实现sftp文件上传下载以及远程执行命令

Paramiko模块是基于Python实现的SSH远程安全连接，用于SSH远程执行命令、文件传输等功能。

 

安装模块

默认Python没有自带，需要手动安装：

pip3 install paramiko

 

二、上传文件

#!/usr/bin/env python3
# coding: utf-8
import paramiko


def sftp_upload_file(host,user,password,server_path, local_path,timeout=10):
    """
    上传文件，注意：不支持文件夹
    :param host: 主机名
    :param user: 用户名
    :param password: 密码
    :param server_path: 远程路径，比如：/home/sdn/tmp.txt
    :param local_path: 本地路径，比如：D:/text.txt
    :param timeout: 超时时间(默认)，必须是int类型
    :return: bool
    """
    try:
        t = paramiko.Transport((host, 22))
        t.banner_timeout = timeout
        t.connect(username=user, password=password)
        sftp = paramiko.SFTPClient.from_transport(t)
        sftp.put(local_path, server_path)
        t.close()
        return True
    except Exception as e:
        print(e)
        return False

 

测试一下上传，完整代码如下：

#!/usr/bin/env python3
# coding: utf-8
import paramiko


def sftp_upload_file(host, user, password, server_path, local_path, timeout=10):
    """
    上传文件，注意：不支持文件夹
    :param host: 主机名
    :param user: 用户名
    :param password: 密码
    :param server_path: 远程路径，比如：/home/sdn/tmp.txt
    :param local_path: 本地路径，比如：D:/text.txt
    :param timeout: 超时时间(默认)，必须是int类型
    :return: bool
    """
    try:
        t = paramiko.Transport((host, 22))
        t.banner_timeout = timeout
        t.connect(username=user, password=password)
        sftp = paramiko.SFTPClient.from_transport(t)
        sftp.put(local_path, server_path)
        t.close()
        return True
    except Exception as e:
        print(e)
        return False


if __name__ == '__main__':
    host = '192.168.10.1'
    user = 'xiao'
    password = 'xiao@1234'

    server_path = '/tmp/tmp.txt'
    local_path = 'D:/text.txt'
    res = sftp_upload_file(host, user, password, server_path, local_path)
    if not res:
        print("上传文件: %s 失败"%local_path)
    else:
        print("上传文件: %s 成功" % local_path)
