查找 Blob 存储中是否存在零字节文件

Question

我有一个包含大量文件（数百万）的 Azure blob 容器。我需要找出是否有文件大小为0字节的文件。有简单的方法吗？

以防万一，容器没有应用任何标签。

Answer 1

以防万一这可能对其他人有帮助，这是我在 powershell 中编写的脚本：

$ctx = New-AzStorageContext -StorageAccountName <AccountName> -StorageAccountKey <PrimaryKey>
$ContainerName = "containerName"
$MaxReturn = 10000
$loopCount = 0
$Total = 0
$Token = $Null

do {
  $Blobs = Get-AzStorageBlob -Context $ctx -Container $ContainerName -MaxCount $MaxReturn -ContinuationToken $Token

  $Total += $Blobs.Count

  foreach ($blobitem in $Blobs) {
    $loopCount += 1
    Write-Host -NoNewline "`rValidating batch: " $loopCount "/" $blobsList.Length " (Current total:" $Total ")"

    if ($blobitem.Length -eq 0) {
      Write-Host ""
      Write-Host "Zero bytes file found: " $blobitem.Name
    }
  }

  $loopCount = 0
  if ($Blobs.Length -le 0) { Break; }
  $Token = $Blobs[$blobs.Count - 1].ContinuationToken;
}
While ($Token -ne $Null)

Write-Host ""
Write-Host "Finished!"

blob_path="give/your/blob/path/here"

files = dbutils.fs.ls(blob_path)

for file in files:
    file_path = file.path
    file_size = file.size
    if(file_size==0):
        print("File size is {0} for file {1}".format(file_size, file_path))
