具有两个输出绑定的Azure函数（Azure队列＆amp; blob存储）

Question

是否可以使用两个输出绑定来编写Azure HTTP触发功能，以便数据不仅输出到Azure队列，还将相同的消息发送到Azure Blob存储中？

Answer 1

请在此处找到多个出站绑定的样本：

    public async Task<IActionResult> Sample(
[HttpTrigger(AuthorizationLevel.Anonymous, "post", Route = "sample")] HttpRequest req,
[Queue("sample", Connection = "StorageAccountString")] CloudQueue sampleQueue,
[Blob("sample", FileAccess.Read, Connection = "StorageAccountString")] CloudBlobContainer sampleContainer,
ExecutionContext context,
ILogger log)
    {
        var requestBody = await req.ReadAsStringAsync().ConfigureAwait(false);

        var queueMessage = new CloudQueueMessage(requestBody);
        await sampleQueue.AddMessageAsync(queueMessage).ConfigureAwait(false);

        CloudBlockBlob blob = sampleContainer.GetBlockBlobReference($"{Guid.NewGuid().ToString()}");
        blob.UploadText(requestBody);

        return new OkResult();
    }

在这里您可以找到多个Blob出站绑定：

        { ImageSize.ExtraSmall, (320, 200) },
        { ImageSize.Small,      (640, 400) },
        { ImageSize.Medium,     (800, 600) }
    };

如果您在一个孤立的过程中运行函数应用程序，Microsoft在此处进行了简短的讨论和示例：
