[英]Can I create a batch program that extracts only one of several IP?
I am trying to create a batch file that port forwards my IP.我正在尝试创建一个端口转发我的 IP 的批处理文件。 The IP can be found with the command ipconfig | findstr IPv4
IP 可以通过命令ipconfig | findstr IPv4
找到。 ipconfig | findstr IPv4
, but there are multiple internet adapters and multiple IP addresses. ipconfig | findstr IPv4
,但有多个互联网适配器和多个 IP 地址。 I want to get only one address like 192.168.40.??
我只想得到一个地址,比如192.168.40.??
192.168.56.1 and 192.168.56.2 is my VirtualBox adapter. 192.168.56.1 和 192.168.56.2 是我的 VirtualBox 适配器。 I'm not sure how to set the condition in the if statement.我不确定如何在 if 语句中设置条件。
This is the Windows batch file (*.bat):这是 Windows 批处理文件 (*.bat):
D:\>ipconfig | findstr IPv4
IPv4 adress . . . . . . . . . : 192.168.56.2
IPv4 adress . . . . . . . . . : 192.168.56.1
IPv4 adress . . . . . . . . . : 192.168.40.19
I tried the following batch file:我尝试了以下批处理文件:
@echo off
setlocal
setlocal enabledelayedexpansion
for /f "usebackq tokens=*" %%a in (`ipconfig ^| findstr IPv4`) do (
for /f delims^=^:^ tokens^=2 %%b in ('echo %%a') do (
for /f "tokens=1-4 delims=." %%c in ("%%b") do (
set _o1=%%c
set _o2=%%d
set _o3=%%e
set _o4=%%f
set _4octet=!_o1:~1!.!_o2!.!_o3!.!_o4!
echo ==start port fowarding==
netsh interface portproxy add v4tov4 listenport=8080 listenaddress=!_4octet! connectport=8080 connectaddress=192.168.56.1
echo ========================
netsh interface portproxy show v4tov4
)
)
)
endlocal
But this runs on all of my adapters:但这在我所有的适配器上运行:
address port address port
--------------- ---------- --------------- ----------
192.168.56.2 8080 192.168.56.1 8080 <- not want
192.168.56.1 8080 192.168.56.1 8080 <- not want
192.168.40.19 8080 192.168.56.1 8080 <- i want only
I then tried:然后我尝试了:
@echo off
setlocal
setlocal enabledelayedexpansion
for /f "usebackq tokens=*" %%a in (`ipconfig ^| findstr IPv4`) do (
for /f delims^=^:^ tokens^=2 %%b in ('echo %%a') do (
for /f "tokens=1-4 delims=." %%c in ("%%b") do (
set _o1=%%c
set _o2=%%d
set _o3=%%e
set _o4=%%f
set _4octet=!_o1:~1!.!_o2!.!_o3!.!_o4!
echo ==start port fowarding==
if !_4octet!==192.168.56.1
(
)
else if !_4octet!==192.168.56.2
(
)
else
netsh interface portproxy add v4tov4 listenport=8080 listenaddress=!_4octet! connectport=8080 connectaddress=192.168.56.1
echo ========================
netsh interface portproxy show v4tov4
)
)
)
endlocal
But I receive the error:但我收到错误:
The syntax of the command is incorrect.该命令的语法不正确。
Perhaps the cause is that the variable (._4octet!) Is not working properly.也许原因是变量 (._4octet!) 工作不正常。
if !_4octet! == 192.168.56.1 (
Can you help me with this problem?你能帮我解决这个问题吗?
If you want to get something like this ip 192.168.40.*
如果你想得到这样的东西 ip 192.168.40.*
You can use a little regex with the command findstr
like this:您可以像这样在命令findstr
中使用一些正则表达式:
ipconfig | findstr IPv4 | findstr /r /c:"192.168.40.*"
You can see more help here findstr /?您可以在这里找到更多帮助findstr /?
/R /C:string Use string as a regular expression. /R /C:string 使用字符串作为正则表达式。
So, with a batch script you can do it to set your IP into Variable like this:因此,您可以使用批处理脚本将 IP 设置为变量,如下所示:
@echo off
SetLocal EnableDelayedExpansion
for /f "usebackq delims=: tokens=2" %%a in (`ipconfig ^| findstr IPv4 ^| findstr /r /c:"192.168.40.*"`) do (
Set "MyIP=%%a"
Set "MyIP=!MyIP!"
set "MyIP=!MyIP: =!"
)
echo MyIP="!MyIP!"
pause
You could use wmic to retrieve the IP Address:您可以使用wmic检索 IP 地址:
@Set "IPA="&For /F Tokens^=2Delims^=^" %%A In ('^""%__AppDir__%wbem\WMIC.exe"^
NICConfig Where "IPEnabled='TRUE' And Not Description Like '%%VirtualBox%%'"^
Get IPAddress 2^>NUL^"')Do @Set "IPA=%%A"
@If Defined IPA Echo=%IPA%&Pause>NUL
