PowerShell function to download files from a GitHub repository

DownloadFilesFromRepo.ps1

function DownloadFilesFromRepo {
Param(
    [string]$Owner,
    [string]$Repository,
    [string]$Path,
    [string]$DestinationPath
    )

    $baseUri = "https://api.github.com/"
    $args = "repos/$Owner/$Repository/contents/$Path"
    $wr = Invoke-WebRequest -Uri $($baseuri+$args)
    $objects = $wr.Content | ConvertFrom-Json
    $files = $objects | where {$_.type -eq "file"} | Select -exp download_url
    $directories = $objects | where {$_.type -eq "dir"}
    
    $directories | ForEach-Object { 
        DownloadFilesFromRepo -Owner $Owner -Repository $Repository -Path $_.path -DestinationPath $($DestinationPath+$_.name)
    }

    
    if (-not (Test-Path $DestinationPath)) {
        # Destination path does not exist, let's create it
        try {
            New-Item -Path $DestinationPath -ItemType Directory -ErrorAction Stop
        } catch {
            throw "Could not create path '$DestinationPath'!"
        }
    }

    foreach ($file in $files) {
        $fileDestination = Join-Path $DestinationPath (Split-Path $file -Leaf)
        try {
            Invoke-WebRequest -Uri $file -OutFile $fileDestination -ErrorAction Stop -Verbose
            "Grabbed '$($file)' to '$fileDestination'"
        } catch {
            throw "Unable to download '$($file.path)'"
        }
    }

}

How will this work if the repository is private? Is there anyone to stick in the oauth token?

I need help with this too.

If the repo is private...

$token = "<Create a Personal Access Token>"
$headers = @{Authorization = "token $($token)"}
Invoke-WebRequest -Headers $headers -Uri $uri

If the repo is private...

$token = "<Create a Personal Access Token>"
$headers = @{Authorization = "token $($token)"}
Invoke-WebRequest -Headers $headers -Uri $uri

Thank you @StanleyGoldman , So difficult to find this specific scenario cleanly presented.

I am new on GitHub. This article was very useful. Thank you very much.

Does this also work with fine grained access tokens? Trying this script out and changing bits here and there but whatever i do, i cant get it to work.

not bad
