1.更新说明接上一期在v1.0.2基础上更新功能1.连接失败时自动清除旧指纹并重连解决一直连接失败的情况2.优化逻辑直接补齐ip即可连接。只有在需要更改固定网段和用户名时选择s3.重构界面更简洁高效让新手也能快速上手2.使用步骤2.1.补齐最后一段ip输入远程主机密码连接成功2.2固定远程设备名和ip在初始界面输入s选择1修改用户名选择2修改固定网段根据你的实际网络地址输入修改完成后按回车返回连接界面2.3连接中断按1可以快速重连刚刚连接的机器输入密码按2可以返回输入IP界面连接其他机器按3可以打开普通终端按q关闭终端退出3.源代码import json import subprocess import sys import time from pathlib import Path from typing import Any, Dict, Optional # --------------------------------------------------------------------------- # 终端样式ANSI # --------------------------------------------------------------------------- class _T: RST \033[0m BOLD \033[1m CYAN \033[36m GREEN \033[32m YELLOW \033[33m RED \033[31m BLUE \033[34m WHITE \033[97m def _enable_ansi_if_windows() - None: if sys.platform !
