1.筆者環境

os：macos

python：3.7.5

2.項目地址

https://gitee.com/goku_black/python-ssh.git

3.依賴來安裝包

pip install paramiko
pip install scp

4.項目結構

├── download_file.py	# 下載文件
├── main.py	# 程序入口
├── settings.py	# 配置
└── upload_file.py	# 上傳文件

5.代碼示例：

# upload_file.py
#!/usr/bin/python
# -*- coding: UTF-8 -*-
