PowerShell DownloadFile（）不适用于Nexus神器下载

我试图从Nexus存储库下载最新的神器。如果我给出确切的zip文件名称，它工作正常。当我尝试使用通用URL（REST URI）进行下载时，它会给我401 Unauthorized。我也尝试过Invoke-WebRequest，WebClient和Invoke-RestMethod。PowerShell DownloadFile（）不适用于Nexus神器下载

$wc = New-Object System.Net.WebClient 
$URL = "http://nexusrepo/nexus/service/local/artifact/maven/redirect?r=my-snapshot&g=my.group.id&a=my.artifact.id&v=1.10.0-SNAPSHOT&c=win32.win32.x86_64&p=zip" 
$username = "nexus" 
$password = "nexus" 
$auth = $username + ":" + $password 
[System.Net.ServicePointManager]::ServerCertificateValidationCallback = {$true} 
$Encoded = [System.Text.Encoding]::UTF8.GetBytes($auth) 
$EncodedPassword = [System.Convert]::ToBase64String($Encoded) 
$wc.Headers.Add("Accept-Encoding", "gzip,deflate") 
$wc.Credentials = New-Object System.Net.NetworkCredential($username, $password) 
$wc.Headers.Add("Authorization", "Basic " + $EncodedPassword) 
$wc.UseDefaultCredentials = $false 
$wc.DownloadFile($URL, "MyApp.zip")

 
Exception calling "DownloadString" with "1" argument(s): "The remote server 
returned an error: (401) Unauthorized."

Nexus服务器上的日志显示什么？ –

我无法访问Nexus服务器的日志。 –

仍在寻找答案。标题信息一旦被重定向就会消失。任何想法我们可以如何在PowerShell中的重定向URL中再次设置Header信息？如果有人能帮助我，请欣赏它。 –

作为一种解决方法，我回到了Invoke-WebRequest并首先使用MaximumRedirection 0获取重定向的URL，然后将该URL作为请求提交。下面的代码工作。

$URL = "http://nexusrepo/nexus/service/local/artifact/maven/redirect?r=my-snapshot&g=my.group.id&a=my.artifact.id&v=1.10.0-SNAPSHOT&c=win32.win32.x86_64&p=zip" 
$username = "nexus" 
$password = "nexus" 
$auth=$username+":"+$password 
$Encoded = [System.Text.Encoding]::UTF8.GetBytes($auth) 
$EncodedPassword = [System.Convert]::ToBase64String($Encoded) 
$latestArtifactURL = Invoke-WebRequest $url -Headers @{Authorization = "Basic $EncodedPassword"} -MaximumRedirection 0 
$redirectedMessage = "$latestArtifactURL".IndexOf('http:') 
$targetURL = "$latestArtifactURL".SubString("$redirectedMessage") 
Invoke-WebRequest $targetURL -Headers @{Authorization = "Basic $EncodedPassword"} -OutFile "MyApp.zip"
