Question

我尝试从https网址下载文件时遇到以下错误。我正在使用Power Shell 3.0

Shell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：

异常调用＆＃34; DownloadFile＆＃34;用＆＃34; 2＆＃34;参数：＆＃34; WebClient请求期间发生异常。＆＃34; 在行：7 char：1 + $ WebClient.DownloadFile（$ Url，$ Path）

有什么建议吗？

Answer 1

在try catch块中包装现有的powershell代码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
}

你的代码中也有拼写错误。检查变量名称。

在脚本中添加了以下命令，现在工作正常

   [System.Net.ServicePointManager]::ServerCertificateValidationCallback = {$true}
    [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
