It is also worth noting that strictly speaking, pushing packages does not require the View privilege, that is a result of the NuGet client sending a GET request (i.e. "list") first before sending the PUT request to push the package -- it's the first request that gets 401ed. You can use the following PowerShell script to perform just the package upload:
$FeedUrl = 'http://proget/nuget/Default'
$FileName = 'C:\tmp\ProGet\packages\Package.1.0\Package.1.0.nupkg'
$APIKey = 'Admin:Admin'
#params([string]$FeedUrl, [string]$FileName, [string]$APIKey)
$req = [System.Net.WebRequest]::CreateHttp($FeedUrl)
$req.Method = 'PUT'
$req.ServicePoint.Expect100Continue = $false
If ($APIKey) {
$req.Headers.Add('X-NuGet-APIKey', $APIKey)
}
$boundary = '---------------------------' + [System.Guid]::NewGuid().ToString('n')
$req.ContentType = "multipart/form-data; boundary=""$boundary"""
$utf8 = New-Object -TypeName System.Text.UTF8Encoding -ArgumentList ($false)
$reqWriter = New-Object -TypeName System.IO.StreamWriter -ArgumentList ($req.GetRequestStream(), $utf8)
$reqWriter.WriteLine("--$boundary")
$reqWriter.WriteLine("Content-Disposition: form-data; name=""package""; filename=""package""")
$reqWriter.WriteLine("Content-Type: application/octet-stream")
$reqWriter.WriteLine()
$reqWriter.Flush()
$fileStream = [System.IO.File]::OpenRead($FileName)
$fileStream.CopyTo($reqWriter.BaseStream)
$fileStream.Close()
$reqWriter.WriteLine()
$reqWriter.Write("--$boundary--")
$reqWriter.Dispose()
$response = $req.GetResponse()
$response.Dispose()
