Kudu REST API Command endpoint error when executing powershell

Question

When trying to execute the POST to /api/command according to this description the following error occurs:

PS C:\\> $Result.Error
remove-item : The Win32 int         


        

Answer 1

After checking this issue on github the correct POSH command should be:

get-childitem -recurse | remove-item -recurse -force

It works well when executing directly from Kudu console or even REST API /api/command endpoint

Answer 2

If the accepted answer isn't appropriate for your situation (i.e. you don't want to use -Recurse on the call to Remove-Item because that would blast an item you want to exclude from deletion, when its containing folder is recursively deleted), the following worked for me:

Get-ChildItem d:\mypath -Recurse -Exclude FileToExclude.ext | Select -ExpandProperty FullName | sort length -Descending | foreach { Remove-Item -Path "$_" -Force }

It seems that simply piping the file object to Remove-Item doesn't work because of this bug, but piping the full filename and then using that as the -Path argument, gets around it.

Answer 3

I can't reproudce the issue that you mentioned. I test with following code,you could refer to it.

$PublishingUsername = "`$userName"

$publishingPassword = "password"

$apiUrl = "https://webAppName.scm.azurewebsites.net/api/command"

$json = @"
{
    "command": 'powershell.exe -command `"get-childitem * -recurse | remove-item -force`"',
    "dir" : 'site\\wwwroot'
 }
"@

$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $PublishingUsername, $publishingPassword)))

$Result = Invoke-RestMethod -Uri $apiUrl -Headers @{Authorization=("Basic {0}" -f $base64AuthInfo)}  -Method Post -Body $json -ContentType "application/json"

Test Result: I aslo check the kudu console that, all of the items under the folder site\wwwroot are deleted.
