如何在Powershell中进行经过身份验证的Web请求？

Question

在C#中,我可能会这样做:

System.Net.WebClient w = new System.Net.WebClient();
w.Credentials = new System.Net.NetworkCredential(username, auth, domain);
string webpage = w.DownloadString(url);

是否有Powershell版本,或者我应该打电话给CLR？

Answer 1

PowerShell几乎完全相同.

$webclient = new-object System.Net.WebClient
$webclient.Credentials = new-object System.Net.NetworkCredential($username, $password, $domain)
$webpage = $webclient.DownloadString($url)

Answer 2

对于需要Powershell返回其他信息的人,比如Http StatusCode,这是一个例子.包括两种最有可能传递凭证的方法.

它是这个SO答案的略微修改版本:
如何在PowerShell中获取数字HTTP状态代码

$req = [system.Net.WebRequest]::Create($url)
# method 1 $req.UseDefaultCredentials = $true
# method 2 $req.Credentials = new NetworkCredential($username, $pwd, $domain); 
try
{
    $res = $req.GetResponse()
}
catch [System.Net.WebException]
{
    $res = $_.Exception.Response
}

$int = [int]$res.StatusCode
$status = $res.StatusCode
return "$int $status"
