Batch file 使用批处理文件将本地IP存储在环境变量中

我试图将我的本地ip存储到一个系统变量中，但我正在努力处理该批处理文件。我已经能够解析我的IP并提取正确的子字符串。然而，声明变量并将其传递给SETX似乎比我想象的要困难

任何帮助都将不胜感激。：）

@echo关闭
延迟扩展
：：这里只是一个示例适配器：
设置“适配器=以太网适配器VirtualBox主机专用网络”
设置adapterfound=false
回声网络连接测试
对于（`ipconfig/all`）中的/f“usebackq令牌=1-2 delims=：”%%f(
设置“项=%%f”
如果/i“！item！”==“！适配器！”(
设置adapterfound=true
)else如果不是“！item！”==”！item:IPv4地址=！“如果”！adapterfound！”==“true”(
echo%%g | cut-d”（“-f1 | tr-d”[：space:]”改进的脚本（可能与区域设置有关）：

另一种方法：

@ECHO OFF
SETLOCAL EnableExtensions DisableDelayedExpansion
:: just a sample adapter here:
set "adapter=Ethernet-Adapter VirtualBox Host-Only Network"
echo Network Connection Test
:: get adapter index
set "_where=where "NetConnectionID = '%adapter%'""
for /F "tokens=1,* delims==" %%G in ('
wmic path Win32_NetworkAdapter %_where% get InterfaceIndex /value ^| findstr "="
') do for /F %%g in ("%%H") do set "_ii=%%~g" 
:: get adapter's IP addresses
set "_where=where "InterfaceIndex = '%_ii%'""
for /F "tokens=1,* delims==" %%G in ('
wmic path Win32_NetworkAdapterConfiguration %_where% get IPAddress /value ^| findstr "="
') do for /F "tokens=1,2 delims={,}" %%g in ("%%H") do (
        set "_IPv4=%%~g" 
        set "_IPv6=%%~h"
      )
set _ip

此处显示了

循环的

%%G
检索所需值
%%g
删除返回值中的结束回车：
wmic
行为：每个输出行以
0x0D0D0A
（
）结束，而不是普通的
0x0D0A
（
）

您知道启用延迟扩展

。然后，使用

！ipadress！

而不是

%ipadress%

！ipadress！给我一个语法错误您需要与此特定适配器关联的确切ipv4地址还是只需要首选的本地ip地址？不幸的是，我需要确切的适配器。但这是wor我只想把“%%g | cut-d”（“-f1 | tr-d”[：space:]”的字符串结果塞进一个变量，然后将其传递给setx命令。

@ECHO OFF
SETLOCAL EnableExtensions EnableDelayedExpansion
::just a sample adapter here:
set "adapter=Ethernet-Adapter VirtualBox Host-Only Network"
set "adapterfound=false"
echo Network Connection Test
for /f "usebackq tokens=1-2 delims=:" %%f in (`ipconfig /all`) do (
    set "item=%%f"
    if not "!item!"=="!item:%adapter%=!" (
        set "adapterfound=true"
        echo %adapter%
    ) else if not "!item!"=="!item:IPv4 Address=!" if "!adapterfound!"=="true" (
           rem                     ↑↑↑↑↑↑↑↑↑↑↑↑ might be locale-dependent
        for /F "delims=( " %%G in ("%%g") do set "ipadress=%%G"
        echo !ipadress!
        rem setx MY_IP !ipadress!
        set "adapterfound=false"
    )
)
echo %ipadress%
