Question

我尝试使用PowerShell从Jenkins下载工件，如下所示：

$webClient = new-object System.Net.WebClient 
$webClient.Credentials = New-Object System.Net.NetworkCredential ("username", "password")
$url = "http://jenkins/job/jobName/lastSuccessfulBuild/artifact/*zip*/archive.zip" 
$localfilename = "C:\Test\archive.zip"  
$webClient.DownloadFile($url, $localfilename)

我得到例外：

使用“2”参数调用“DownloadFile”的异常：“遥控器服务器返回错误：（403）禁止。“在C：\ ps2.ps1：20 char：28 + $ webclient.DownloadFile＆lt;＆lt;＆lt;＆lt; （$ url，$ localfilename） + CategoryInfo：NotSpecified：（:) []，MethodInvocationException + FullyQualifiedErrorId：DotNetMethodException

如果我尝试使用wget下载工件，它可以工作：

wget --auth-no-challenge --http-user=username --http-password=password http://jenkins/job/jobName/lastSuccessfulBuild/artifact/*zip*/archive.zip

如果我使用不带参数--auth-no-challenge的wget，我会收到同样的错误 - Forbidden。

Answer 1

在请求标头中使用此授权非常有效：

# Create web client with authorization header
$webClient = new-object System.Net.WebClient 
$credentialAsBytes = [System.Text.Encoding]::ASCII.GetBytes($userName + ":" + $password)
$credentialAsBase64String = [System.Convert]::ToBase64String($credentialAsBytes);
$webClient.Headers[[System.Net.HttpRequestHeader]::Authorization] = "Basic " + $credentialAsBase64String;

Answer 2

您是否在Jenkins盒子上设置了基本身份验证？如果是这样，试试这个

$webClient = new-object System.Net.WebClient 
$creds = New-Object System.Net.NetworkCredential ("username", "password")
$url = "http://jenkins/job/jobName/lastSuccessfulBuild/artifact/*zip*/archive.zip" 
$localfilename = "C:\Test\archive.zip"  
$cache = new-object System.Net.CredentialCache
$cache.Add($url, "Basic", $creds)
$webclient.Credentials = $cache
$webClient.DownloadFile($url, $localfilename)

Answer 3

我还没有在Jenkins上试过这个，但这就是我用来下载附加到Jira（https）中的问题的文件：

Invoke-WebRequest -uri "https://jira.xyz.com/login.jsp?os_username=$username&os_password=$jiraPassword&os_cookie=true" -UserAgent ([Microsoft.PowerShell.Commands.PSUserAgent]::InternetExplorer) -SessionVariable myWebSession

Invoke-WebRequest -uri $fileUrlPath -LocalOutFilePath $file -method get -UserAgent ([Microsoft.PowerShell.Commands.PSUserAgent]::InternetExplorer) -WebSession $myWebSession

自 Jenkins 2.0 起，clipBehaviour 需要提供会话 cookie。在这种情况下，您需要额外的步骤：

$crumbParams = @{
    Headers = @{'Authorization' = 'Basic ' + [System.Convert]::ToBase64String([System.Text.Encoding]::UTF8.GetBytes("$($credentials.UserName):$($credentials.GetNetworkCredential().Password)"))}
    Uri = "$baseUri/crumbIssuer/api/json"
    SessionVariable = 'crumbSession'
}
[void] (Invoke-RestMethod @crumbParams)

请注意，如果您提供带有域的凭据，如果 Jenkins 只需要用户名而不需要域，则您可能必须使用 $credentials.GetNetworkCredential().UserName。 $baseUri 是 Jenkins 地址，包括 http(s)://。

前面的命令会将会话状态保存在 $crumbSession 中，您可以从中提取所需的 cookie 标头：

$webClient = New-Object System.Net.WebClient
$webClient.Headers.Add([System.Net.HttpRequestHeader]::Cookie, $crumbSession.Cookies.GetCookieHeader($baseUri))
$webClient.Headers.Add([System.Net.HttpRequestHeader]::Authorization, 'Basic ' + [System.Convert]::ToBase64String([System.Text.Encoding]::UTF8.GetBytes("$($credentials.UserName):$($credentials.GetNetworkCredential().Password)")))
$webClient.DownloadFile($url, $localfilename)
