powershell - 如何用powershell下载文件？

问题描述

过去我确实使用过：

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

$url = "https://nodejs.org/dist/v14.17.6/node-v14.17.6-x64.msi"
$folder = "C:\Users\test\Downloads"

$WebClient = New-Object System.Net.WebClient
$WebClient.DownloadFile($url, $folder)

当我今天尝试时，它显示此错误

  Exception calling "DownloadFile" with "2" argument(s): "An exception occurred during a WebClient request."
  At line:1 char:5
  +     $WebClient.DownloadFile($url, $folder)
  +     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
      + FullyQualifiedErrorId : WebException

我试图用找到的建议来修复，但没有一个奏效。

解决方案

您需要提取文件名，以便获得 outfile 的完整路径，但这将起作用：

$url = "https://nodejs.org/dist/v14.17.6/node-v14.17.6-x64.msi"
$fullPath = "C:\Users\test\Downloads\node-v14.17.6-x64.msi"
Invoke-WebRequest $url -outfile $fullPath
