c# - 指定的容器不存在

Question

遇到此错误指定的容器不存在。

让我解释一下，

CloudBlobClient blobStorage = GetBlobStorage("upload");
CloudBlockBlob blob = BlobPropertySetting(blobStorage, Guid.NewGuid().ToString().ToLower() + Path.GetExtension(file.FileName));
blob.UploadFromStream(file.InputStream);

public static CloudBlobClient GetBlobStorage(string cloudBlobContainserName)
{
    CloudBlobClient blobStorage;

    try
    {
        var storageAccount = CloudStorageAccount.FromConfigurationSetting("StorageConnectionString");
        blobStorage = storageAccount.CreateCloudBlobClient();
        CloudBlobContainer container = blobStorage.GetContainerReference(cloudBlobContainserName); 

        container.CreateIfNotExist();

        var permissions = container.GetPermissions();
        permissions.PublicAccess = BlobContainerPublicAccessType.Container;

        container.SetPermissions(permissions);
    }
    catch (Exception ex)
    {
        Logger.LogError(Log4NetLogger.Category.Exception, "Error in : BlobHandler.GetBlobStorage :>> Exception message: " + ex.Message);
        throw;
    }

    return blobStorage;
}

public static CloudBlockBlob BlobPropertySetting(CloudBlobClient cloudBlobClientReferenceName, string blobContentName)
{
    return cloudBlobClientReferenceName.GetBlockBlobReference(blobContentName);
}

我的StorageConnectionString是

<Setting name="StorageConnectionString" value="DefaultEndpointsProtocol=https;AccountName=duw;AccountKey=bla bla" />

容器“upload”和存储帐户“duw”存在。

执行blob.UploadFromStream(file.InputStream);语句会导致错误。

堆栈跟踪:

内部异常:

{“远程服务器返回错误:(404) 未找到。”}

任何人都可以帮我解决这个问题吗？

简短版本

尝试使用以下代码来实现 BlobPropertySetting 函数:

 public static CloudBlockBlob BlobPropertySetting(CloudBlobClient cloudBlobClientReferenceName, string blobContentName)
    {
        CloudBlockBlob blob = cloudBlobClientReferenceName.GetBlockBlobReference("upload/" + blobContentName);
        return blob;
    }

现在是更长的版本:)

您收到此错误的原因是您在 BlobPropertySetting 方法中构造 CloudBlockBlob 对象的方式所致。当您使用代码时，它会创建一个具有以下 URI 的 blob 对象:https://duv.blob.core.windows.net/blobContentName。如果您注意到，那里没有容器名称。由于没有容器名称，存储客户端库假定您尝试在 $root Blob 容器中创建 Blob，这是一个特殊的 Blob 容器。您可以在这里阅读更多相关信息:http://msdn.microsoft.com/en-us/library/windowsazure/hh488356.aspx 。由于您的存储帐户没有此容器，因此您会收到 404 - Resource Not Found 错误。
