c# - 创建并上传追加 Blob 以存储在 Azure 容器中

Question

每当消息从服务总线传入时，我都会尝试将新的追加 blob 文件上传到容器。我不想追加到已经存在的 blob 中。我想创建一个全新的追加 blob 并将其添加到末尾。

这可能吗？

我正在看这篇文章，但当他们到达内容部分时，我无法安静地理解他们的意思:https://azuresdkdocs.blob.core.windows.net/$web/javascript/azure-storage-blob/12.1.1/classes/appendblobclient.html#appendblock

这是我到目前为止的代码:

public static async void StoreToBlob(Services service)
    {
        //Serealize Object 
        var sender = JsonConvert.SerializeObject(service);

        // Create a BlobServiceClient object which will be used to create a container client
        BlobServiceClient blobServiceClient = new BlobServiceClient(connectionString);

        // Create the container and return a container client object
        BlobContainerClient containerClient = blobServiceClient.GetBlobContainerClient(containerName);

        // Create the container if it doesn't already exist.  
        await containerClient.CreateIfNotExistsAsync();

        //Reference to blob
        AppendBlobClient appendBlobClient = containerClient.GetAppendBlobClient("services" + Guid.NewGuid().ToString() + ".json");

        // Create the blob. 
        appendBlobClient.Create();

        await appendBlobClient.AppendBlock(sender, sender.Length); //here is where I am having an issue
    }

Answer 1

您可以尝试类似以下内容(未测试的代码):

byte[] blockContent = Encoding.UTF8.GetBytes(sender);
using (var ms = new MemoryStream(blockContent))
{
    appendBlobClient.AppendBlock(ms, blockContent.Length);
}

本质上，我们将字符串转换为字节数组，从中创建一个流，然后上传该流。
