Powershell是否会在下载失败时调用WebRequest抛出错误？

# 导入WebRequest模块
Import-Module -Name Microsoft.PowerShell.Utility

# 定义下载链接和保存路径
$downloadUrl = "https://example.com/file.txt"
$savePath = "C:\Downloads\file.txt"

# 创建WebRequest对象
$webRequest = [System.Net.WebRequest]::Create($downloadUrl)

# 发送请求并获取响应
$response = $webRequest.GetResponse()

# 检查HTTP状态码
if ($response.StatusCode -eq [System.Net.HttpStatusCode]::OK) {
    # 下载文件
    $responseStream = $response.GetResponseStream()
    $fileStream = [System.IO.File]::Create($savePath)
    $responseStream.CopyTo($fileStream)
    $fileStream.Close()
    $responseStream.Close()
} else {
    # 下载失败，抛出错误
    throw "文件下载失败，HTTP状态码: $($response.StatusCode)"
}
