如何在一个变量批处理脚本中存储url的响应

Question

我试图将URL的响应存储到批处理脚本中的变量

的例子:

set initial=PowerShell -Command "(new-object net.webclient).DownloadString('https://some-url/id')"

我试图存储的响应:

PowerShell -Command "(new-object net.webclient).DownloadString('https://some-url/id')"

变量:

initial

但这不起作用。我怎样才能实现我的目标?

Answer 1

使用for /f。像这样。

for /f "usebackq delims=" %%a in (`PowerShell -Command "(new-object net.webclient).DownloadString('https://some-url/id')"`) do set initial=%%a

Answer 2

这是一个展示如何获取公共ip地址的示例:

@echo off
set "URL=http://myexternalip.com/raw"
Call :GetResponse %URL%
echo %initial% 
Pause>nul & exit
::*****************************************************************
:GetResponse <URL>
for /f "usebackq delims=" %%a in (`PowerShell -Command "(new-object net.webclient).DownloadString('%1')"`) do set "initial=%%a"
Exit /b
