使用powershell将Google.Protobuf/3.1.0 nuget包下载到本地机器

Question

我已经在下面的博客中获得了这个脚本，它将使用power-shell脚本将所有nuget包下载到我的本地服务器。我已经使用相同的脚本将Google.Protobuf/3.1.0 Nuget包下载到本地驱动器。这对一个特定的包页面 -

https://www.nuget.org/packages/Google.Protobuf/3.1.0/不是供稿网址基地脚本。

在我看来是这样的：

$serviceBase = GetPackageUrl($feedUrlBase) 
$feedUrl = $serviceBase + "Packages" 

可以只用

$feedUrl = "http://packages.nuget.org/v1/FeedService.svc/Packages" 

，如果你很高兴来限制自己nuget.org更换......。
