查找文件現在,你扔出去找-ChildItem -Recurse的超級簡單的答案之前,這是我唯一的問題:如何通過目錄樹遞歸使用PowerShell
我遠程連接使用PowerShell到Azure ,抓取站點(槽)列表,然後遍歷站點並使用Kudu API查找目錄結構中的所有圖像。由於Kudu沒有遞歸的概念,我必須構建自己的遞歸函數來抓取根目錄中的所有圖像,然後遍歷所有兒童和孩子的孩子等,以便在這些目錄中找到圖像文件。
這裏是我連接到Azure和抓根目錄代碼:
function Get-AzureRmWebAppPublishingCredentials($resourceGroupName, $webAppName, $slotName = $null){
if ([string]::IsNullOrWhiteSpace($slotName)){
$resourceType = "Microsoft.Web/sites/config"
$resourceName = "$webAppName/publishingcredentials"
}
else{
$resourceType = "Microsoft.Web/sites/slots/config"
$resourceName = "$webAppName/$slotName/publishingcredentials"
}
$publishingCredentials = Invoke-AzureRmResourceAction -ResourceGroupName $resourceGroupName -ResourceType $resourceType -ResourceName $resourceName -Action list -ApiVersion 2015-08-01 -Force
return $publishingCredentials
}
function Get-KuduApiAuthorisationHeaderValue($resourceGroupName, $webAppName, $slotName = $null){
$publishingCredentials = Get-AzureRmWebAppPublishingCredentials $resourceGroupName $webAppName $slotName
return ("Basic {0}" -f [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $publishingCredentials.Properties.PublishingUserName, $publishingCredentials.Properties.PublishingPassword))))
}
function Fill-MimeTypes(){
return @("image/gif", "image/x-icon", "image/jpeg", "image/png", "image/tiff", "image/bmp")
}
$MimeTypes = Fill-MimeTypes
[System.Collections.ArrayList]$Directories = @()
#Login to Azure Account
Login-AzureRmAccount
#Get the Azure subscription
Select-AzureRmSubscription -SubscriptionName [Subscription Name]
#Get the resource group name
$resourceGroupName = [Resource Group Name]
#Get the WebApp name
$Resources = Find-AzureRmResource -ResourceType Microsoft.Web/sites -ResourceGroupNameContains $resourceGroupName
ForEach($Resource in $Resources)
{
#Get the WebAppName
$WebAppName = $Resource.Name
#Now, get the publishing creds
$publishingCredentialsHeader = Get-KuduApiAuthorisationHeaderValue $resourceGroupName $WebAppName $null
$ApiUrl = "https://$WebAppName.scm.azurewebsites.net/api/vfs/site/wwwroot/"
#Now get the list of files in the wwwroot directory
$InitialList = Invoke-RestMethod -Uri $ApiUrl -Headers @{Authorization=$publishingCredentialsHeader} -Method GET -ContentType "application/json"
ForEach($Item in $InitialList)
{
If($MimeTypes -Contains $Item.mime)
{
#Add image file data to a collection
}
If ($Item.mime -eq "inode/directory")
{
#So, here is where I need to recurse...
#The mime type of inode/directory means it's a directory ;)
#I now need to call the Api again with the Url and get the contents of the current directory and rinse and repeat until done
#But I cannot forget about the other directories in the root directory and their children.
}
}
}
如何我寫的遞歸函數?
Up one ..對如何在沒有Get-ChildItem的情況下執行此操作感興趣。一個自定義函數可以有額外的參數,在正確的情況下非常有用 – cet51
你已經演示瞭如何編寫和調用函數,並且你已經寫了評論,你需要做什麼 - 「##添加圖像文件數據到一個集合*「 - 我想你知道如何做這個位? 「*#我現在需要再次調用Api與Url *」 - 這一點?所以你的問題真的「解釋遞歸給我?」有各種語言的遞歸目錄遍歷示例 - https://stackoverflow.com/q/24783862/478656或https://rosettacode.org/wiki/Walk_a_directory/遞歸 - 哪種方法可以執行遞歸漫遊模式或另一個 – TessellatingHeckler
,這個模式或多或少是你在你的評論中寫的,例如函數遞歸 - 步行{將文件添加到集合;對於每個目錄:Recursive-Walk $ directory}; 「*我不能忘記根目錄中的其他目錄*」 - 你不能忘記它們,它們被保存在運行代碼的結構中,就像'1..10 | foreach {process-number $ _}'在函數調用時不會忘記數字 – TessellatingHeckler
