一、从FinalShell获取服务器基本信息

如图操作会导出一个json文件，可以直接保存在桌面，或者其他位置

json格式如下：

{"forwarding_auto_reconnect":false ,"custom_size":false ,"delete_time":0 ,"secret_key_id":"" ,"user_name":"root" ,"remote_port_forwarding":{} ,"conection_type":100 ,"sort_time":0 ,"description":"" ,"proxy_id":"0" ,"authentication_type":1 ,"drivestoredirect":true ,"delete_key_sequence":0 ,"password":"xE4F2Pi13TnbkO8vo6wwmQNbqB77PUeI" ,"modified_time":1700460445433 ,"host":"x.xx.xx.xx" ,"accelerate":false ,"id":"sn1xqbrr5womw787" ,"height":0 ,"order":0 ,"create_time":1700460445433 ,"port_forwarding_list":[] ,"parent_update_time":0 ,"rename_time":0 ,"backspace_key_sequence":2 ,"fullscreen":false ,"port":22 ,"terminal_encoding":"UTF-8" ,"parent_id":"root" ,"exec_channel_enable":true ,"width":0 ,"name":"xx.xx.xx.xx" ,"access_time":1719895278353}

二、代码读取并解析获取账号明文信息

三、执行main方法，获取信息

这样就获取到了！
