如何使用 PowerShell 下载完整的存储库？

Question

我使用这个 power shell 脚本从 Git Hub 存储库下载文件

$url = "https://gist.github.com/ . . ./test.jpg"
$output = "C:\Users\admin\Desktop\test.jpg"
$start_time = Get-Date

$wc = New-Object System.Net.WebClient
$wc.DownloadFile($url, $output)
#OR
(New-Object System.Net.WebClient).DownloadFile($url, $output)

Write-Output "Time taken: $((Get-Date).Subtract($start_time).Seconds) second(s)" 

它适用于一个文件。如何使用 PowerShell 下载完整的存储库？我无法使用git pull.

编辑 这是我在真实存储库上尝试的内容。

存储库：https : //github.com/githubtraining/hellogitworld/archive/master.zip

这是一个测试代码，但它没有完全下载存储库

$url = "https://github.com/githubtraining/hellogitworld/archive/master.zip"
$output = "C:\Users\mycompi\Desktop\test\master.zip"
$start_time = Get-Date

$wc = New-Object System.Net.WebClient
$wc.DownloadFile($url, $output)

Write-Output "Time taken: $((Get-Date).Subtract($start_time).Seconds) second(s)"

您可以从以下 URL 下载位于当前 HEAD 的分支的压缩副本：

https://github.com/[owner]/[repository]/archive/[branch].zip

例如，要在 GitHub 上下载 PowerShell 存储库的当前主分支，您需要执行以下操作：

$url = "https://github.com/PowerShell/PowerShell/archive/master.zip"
$output = "C:\Users\admin\Desktop\master.zip"
$start_time = Get-Date

$wc = New-Object System.Net.WebClient
$wc.DownloadFile($url, $output)

Write-Output "Time taken: $((Get-Date).Subtract($start_time).Seconds) second(s)" 

你可以很容易地把它变成一个可重用的函数：

function Save-GitHubRepository
{
    param(
        [Parameter(Mandatory)]
        [string]$Owner,

        [Parameter(Mandatory)]
        [string]$Project,

        [Parameter()]
        [string]$Branch = 'master'
    )

    $url = "https://github.com/$Owner/$Project/archive/$Branch.zip"
    $output = Join-Path $HOME "Desktop\${Project}-${Branch}_($(Get-Date -Format yyyyMMddHHmm)).zip"
    $start_time = Get-Date

    $wc = New-Object System.Net.WebClient
    $wc.DownloadFile($url, $output)

    Write-Host "Time taken: $((Get-Date).Subtract($start_time).TotalSeconds) second(s)" 
}

然后像这样使用它：
