从 URL 下载 Windows 批处理文件 [英] Windows batch file file download from a URL

问题描述

我正在尝试从网站下载文件(例如 http://www.example.com/package.zip) 使用 Windows 批处理文件.我在编写以下函数时收到错误代码:

I am trying to download a file from a website (ex. http://www.example.com/package.zip) using a Windows batch file. I am getting an error code when I write the function below:

xcopy /E /Y "http://www.example.com/package.zip"

批处理文件似乎不喜欢 http 后面的/".有没有办法转义这些字符，使其不假定它们是函数参数?

The batch file doesn't seem to like the "/" after the http. Are there any ways to escape those characters so it doesn't assume they are function parameters?

推荐答案

使用 PowerShell 2.0(预装 Windows 7)，您可以使用:

With PowerShell 2.0 (Windows 7 preinstalled) you can use:

(New-Object Net.WebClient).DownloadFile('http://www.example.com/package.zip', 'package.zip')

从 PowerShell 3.0(预装 Windows 8)开始，您可以使用 Invoke-WebRequest:

Starting with PowerShell 3.0 (Windows 8 preinstalled) you can use Invoke-WebRequest:

Invoke-WebRequest http://www.example.com/package.zip -OutFile package.zip

从批处理文件中调用它们:

From a batch file they are called:

powershell -Command "(New-Object Net.WebClient).DownloadFile('http://www.example.com/package.zip', 'package.zip')"
powershell -Command "Invoke-WebRequest http://www.example.com/package.zip -OutFile package.zip"

(PowerShell 2.0 可在 XP 上安装，3.0 可用于 Windows 7)

(PowerShell 2.0 is available for installation on XP, 3.0 for Windows 7)
