azure.storage.blobs。身份验证错误编写元数据

Question

我目前正在尝试从不推荐使用的Windowsazure.storage转换为azure.storage.blobs。转换的测试持续了几个小时，然后突然间，我在写信给元数据时开始遇到认证错误。斑点存储本身的读写本身可以正常工作。身份验证错误仅在写入元数据时才发生。

错误详细信息：

我的元数据属性代码：

public IDictionary<string, string> MetaData
{
    get
    {
        IDictionary<string, string> Result = new Dictionary<string, string>();

        Retry( () =>
               {
                   var Props = BlobClient.GetProperties();
                   Result = Props.Value.Metadata;
               } );

        return Result;
    }

    set
    {
        Retry( () =>
               {
                   BlobClient.SetMetadata( value );
               } );
    }
}

关于为什么仅在元数据上发生这种情况的任何想法。

Answer 1

我发现了。这是因为元数据在文本的末尾有一条新线。看来元数据主体只能是单线文本。
