c# - Azure Blob 存储下载所有文件

Question

我想从容器“$logs”下载所有文件，但抛出 StorageException。

CloudStorageAccount storageAccount = CloudStorageAccount.Parse("DefaultEndpointsProtocol=https;AccountName=" + accName + ";AccountKey=" + accKey);

CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();

CloudBlobContainer container = blobClient.GetContainerReference("$logs");

IEnumerable<IListBlobItem> ListBlobs = container.ListBlobs(string.Empty, true);

foreach (var item in ListBlobs)
{
    CloudBlockBlob blockBlob = container.GetBlockBlobReference(item.ToString());
    string path= (@"C:\Users\Ay\Downloads\AzureLogs");
    blockBlob.DownloadToFile(path, FileMode.Open);
}

问题是什么？

Answer 1

问题是 item.ToString() 将返回“Microsoft.WindowsAzure.Storage.Blob.CloudBlockBlob”，因此不存在这样的 blob，从而导致 404 错误。

将该行更改为

CloudBlockBlob blockBlob = container.GetBlockBlobReference(((CloudBlockBlob)item).Name);

编辑: 本地写入文件的代码也不正确。 试试这个

foreach (var item in ListBlobs)
{
    string name = ((CloudBlockBlob) item).Name;
    CloudBlockBlob blockBlob = container.GetBlockBlobReference(name);
    string path = (@"C:\Users\Ay\Downloads\AzureLogs\" + name);
    blockBlob.DownloadToFile(path, FileMode.OpenOrCreate);
}
