Uploading folders in sharepoint from powershell

Ankit007 

You could modify the UPLOAD-FILE function to skip files with a .zip extension and assign them to the $file value for upload.

# upload the file
Function UPLOAD-FILE
{
    param($workingDir, $tempDir, $clientId, $clientSecret, $artifactname)
  
    
    Get-ChildItem $workingDir | ForEach-Object {
    
    $name = $_.FullName.Split("\")[-1]
    if ($name -contains ".zip") {
          #skip file
          $file = $_.FullName + "\" +$tempDir + "\" + "$($name)"
    }
    else {
         CREATE-ARCHIVE -workingDir $_.FullName -tempDir $tempDir -name $name
         $file = $_.FullName + "\" +$tempDir + "\" + "$($name).zip"
    }
    
    $fileSize = (Get-Item $file).length       
    $uploadURLObject = GET-UPLOADLINK -clientId $clientId -clientSecret $clientSecret -artifactname $name
    $tokenObject = GET-TOKEN -clientId $clientId -clientSecret $clientSecret
    $uploadHeaders = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"
    $uploadHeaders.Add("Content-Type", "application/json")
    $uploadHeaders.Add("Content-Range", "bytes " + 0 +"-" + ($fileSize-1) + "/" + $fileSize)
    $uploadHeaders.Add("Content-Length", $fileSize)
    $uploadHeaders.Add("Authorization", "Bearer "+ $tokenObject.access_token)    
    $uploadBody = [System.IO.File]::ReadAllBytes($file)
    $response = Invoke-RestMethod $uploadURLObject.uploadUrl -Method 'PUT' -Headers $uploadHeaders -Body $uploadBody
    $response | ConvertTo-Json  
    REMOVE-TEMPDIR -workingDir $_.FullName -tempDir $tempDirectory
    }
    
    
}
