Question

我在这里有一个powershell脚本：

https://github.com/Azure/azure-devtestlab/blob/master/Artifacts/windows-vsts-download-and-run-script/DownloadVstsDropAndExecuteScript.ps1

我用来下载VSTS构建工件的

。当我在Powershell中运行脚本时，该脚本可以完美运行。当我像这样从命令提示符运行它时，它可以正常工作

powershell.exe -ExecutionPolicy Bypass C:\PathToScript\DownloadVstsDropAndExecuteScript.ps1 -parameters

但是，当我尝试将其作为计划任务运行时，脚本似乎无法完成下载（zip文件大小很小，当我尝试打开时，文件已损坏）。既可以使用用户登录模式，也可以不使用登录用户。

Answer 1

已替换

Invoke-RestMethod -Uri "$downloadUrl" -Headers $Headers -Method Get -Outfile $outfile | Out-Null

与

$wc = New-Object System.Net.WebClient
    foreach ($key in $Headers.Keys) {
        $wc.Headers.Add($key, $Headers[$key])
    }
    $wc.DownloadFile($downloadUrl, $outfile)
