PowerShell:从GitHub检索文件 [英] PowerShell : retrieve file from GitHub

问题描述

我需要从GitHub私有存储库下载文件.因此，按照GitHub网站上的说明，我为自己的凭据创建了OAuth令牌.

I need to download a file from my GitHub private repo. So following the instructions on the GitHub site, I created an OAuth token for my credentials.

然后我执行了这个PS脚本:

Then I executed this PS script :

$WebClient = New-Object -TypeName System.Net.WebClient
$WebClient.Headers.Add('Authorization','{OAuth token}')
$uri = "https://github.com/mycompany/myrepo/blob/master/myfile.zip"
$targetPath = "c:\temp"
$WebClient.DownloadFile($uri, $targetPath)

但是，$WebClient.DownloadFile()返回404.这很奇怪，因为我可以通过登录到GitHub的浏览器使用创建OAuth令牌的相同凭据从$uri检索文件.

However, $WebClient.DownloadFile() returns a 404. This is strange because I can retrieve the file from $uri via a browser logged-in to GitHub with same credentials used to create OAuth token.

推荐答案

根据

According to this your two options are HTTPS basic auth and an OAuth token.

因此要将基本身份验证添加到您的Web客户端，请尝试以下操作:

So to add basic auth to your webclient try this:

$url = 'https://github.com/mycompany/myrepo/blob/master/myscript.ps1'
$wc = New-Object -TypeName System.Net.WebClient
$wc.Credentials = New-Object -TypeName System.Net.NetworkCredential 'username', 'password'
iex ($wc.DownloadString($url))

要使用OAuth，您需要添加一个名为Authorization的标头并提供令牌字符串作为参数.以此替换上面示例中的NetworkCredential行.

To use OAuth you'll need to add a header named Authorization and provide the token string as an argument. Replace the NetworkCredential line from the example above with this.

$wc.Headers.Add('Authorization','token your_token')

按照说明此处使用 curl 创建OAuth令牌.这部分可以使用PowerShell来完成，但这只是一次性的事情，因此您可以仅使用GitHub提供的示例.

Follow the instructions here to create the OAuth token using curl. This part can be done with PowerShell but it's only a one time thing so you can just use the example GitHub provides.
