我在使用check connection命令时遇到问题，因为它无法继续执行if

推荐答案

这将ping www.google.com，如果有响应，则为goto :a，如果未连接，则为goto :Disconnected.

This will ping www.google.com and if there is a response then goto :a, if not connected then it will goto :Disconnected.

findstr将在ping输出中查找TTL(生存时间).很棒的小技巧，可以应用于多种情况.

The findstr will look for the TTL (Time to live) in the ping output. Great little trick that can be applied to multiple situations.

ping -n 1 www.google.com | findstr TTL && goto a
ping -n 1 www.google.com | findstr TTL || goto Disconnected

:a
REM Your connected script here

:Disconnected
REM Your disconnect / reconnect script here

您也可以将其浓缩为以下内容.因为如果脚本不执行findstr TTL，脚本将继续执行；如果不执行，则跳至:a

You could also condense this to the below. As the script will continue if it does not findstr TTL or skip to :a if it does

ping -n 1 www.google.com | findstr TTL && goto a
REM Your disconnect / reconnect script here

:a
REM Your connected script here
