.Synopsis Download Artifacts .Description Download artifacts from artifacts storage .Parameter artifactUrl Url for application artifact to use. .Parameter includePlatform Add this switch to include the platform artifact in the download .Parameter force Add this switch to force download artifacts even though they already exists .Parameter forceRedirection Add this switch to force download redirection artifacts even though they already exists .Parameter basePath Load the artifacts into a file structure below this path. (default is c:\bcartifacts.cache) .Parameter timeout Timeout in seconds for each file download. .Example $artifactPaths = Download-Artifacts -artifactUrl $artifactUrl -includePlatform $appArtifactPath = $artifactPaths[0] $platformArtifactPath = $artifactPaths[1] .Example $appArtifactPath = Download-Artifacts -artifactUrl $artifactUrl #> function Download-Artifacts { Param ( [Parameter(Mandatory=$true)] [string] $artifactUrl, [switch] $includePlatform, [switch] $force, [switch] $forceRedirection, [string] $basePath = "", [int] $timeout = 300 ) if ($basePath -eq "") { $basePath = $navcontainerhelperConfig.bcartifactsCacheFolder } if (-not (Test-Path $basePath)) { New-Item $basePath -ItemType Directory | Out-Null } do { $redir = $false $appUri = [Uri]::new($artifactUrl) $appArtifactPath = Join-Path $basePath $appUri.AbsolutePath $exists = Test-Path $appArtifactPath if ($exists -and $force) { Remove-Item $appArtifactPath -Recurse -Force $exists = $false } if ($exists -and $forceRedirection) { $appManifestPath = Join-Path $appArtifactPath "manifest.json" $appManifest = Get-Content $appManifestPath | ConvertFrom-Json if ($appManifest.PSObject.Properties.name -eq "applicationUrl") { # redirect artifacts are always downloaded Remove-Item $appArtifactPath -Recurse -Force $exists = $false } } if (-not $exists) { Write-Host "Downloading application artifact $($appUri.AbsolutePath)" $appZip = Join-Path ([System.IO.Path]::GetTempPath()) "$([Guid]::NewGuid().ToString()).zip" try { TestSasToken -sasToken $artifactUrl Download-File -sourceUrl $artifactUrl -destinationFile $appZip -timeout $timeout } catch { if ($artifactUrl.Contains('.azureedge.net/')) { $artifactUrl = $artifactUrl.Replace('.azureedge.net/','.blob.core.windows.net/') Write-Host "Retrying download..."
