我正在尝试编写一个与 wifi 网络断开连接并在一段时间后重新连接到同一网络的批处理脚本。在这种情况下，它必须记住之前连接的网络 SSID，例如将其存储到变量中。
netsh wlan disconnect
timeout 5
netsh wlan connect name=PreviousNetwork
我可以从中找到 SSID 名称
netsh wlan show networks interface="Wi-Fi" mode=ssid
但是我该如何存储呢？

这是一个方法，请尝试一下：
@echo off
Title How to assign the SSID of current connected wifi network to a variable in a batch script
for /f "delims=: tokens=2" %%n in (
'netsh wlan show interface name="Wi-Fi" ^| find /i "PROFIL"'
) do set "Network=%%n"
Call :Trim "%Network%" Connected_SSID
echo The Current SSID Connected is : "%Connected_SSID%"
echo Did you want to disconnect from this SSID "%Connected_SSID%" ?
pause
cls & echo( & color 0C
netsh wlan disconnect
TimeOut /T 5 /NoBreak>nul
cls & echo( & color 0A
echo Did you want to re-connect to this SSID : "%Connected_SSID%" ?
pause
netsh wlan connect name="%Connected_SSID%"
Pause & Exit

:Trim <String>
(
echo Wscript.echo Trim("%~1"^)
)>"%tmp%\%~n0.vbs"
@for /f "delims=" %%a in ('Cscript /nologo "%tmp%\%~n0.vbs"') do set "%2=%%a"
exit /b

【讨论】：
for /f "tokens=*" %%_ IN ("%~1") DO SET "%2=%%_" 无需 VBScript 或写入磁盘。
for /f "tokens=*" %%_ IN ("%~1") DO SET "%2=%%~nx_"没有必要使用VB 或写入磁盘，这将根据您的目的左右修剪。 TBF 你甚至不需要调用标签for /f "delims=: tokens=2" %%_ in ('netsh wlan show interface name="Wi-Fi" ^| find /i "PROFIL"') do set "Network=%%~nx_"
