powershell - 尝试使用 Powershell 下载文件时出错

Question

当我尝试从 https URL 下载文件时，出现以下错误。我正在使用 Power Shell 3.0

外壳脚本

$Username = 'user'
$Password = 'password'
$Url = "url"
$Path = "path"
$WebClinet = New-Object System.Net.WebClient
$WebClient.Credentials = New-Object System.Net.Networkcredential($Username, $Password)
$WebClient.DownloadFile( $Url, $Path )

错误:

使用“2”个参数调用“DownloadFile”时发生异常:“WebClient 请求期间发生异常。”在行:7 字符:1+ $WebClient.DownloadFile( $Url, $Path )

有什么建议吗？

Answer 1

将您现有的 powershell 代码包装在一个 try catch block 中，并写出异常详细信息，以便了解导致问题的实际错误。

Try
{
    $Username = 'user'
    $Password = 'password'
    $Url = "url"
    $Path = "path"
    $WebClient = New-Object System.Net.WebClient
    $WebClient.Credentials = New-Object System.Net.Networkcredential($Username, $Password)
    $WebClient.DownloadFile( $Url, $Path )
}
Catch [Exception]
{
    Write-Host $_.Exception | format-list -force
}

而且您的代码中也有错别字。检查您的变量名称。
