如果要通过队列触发器将队列消息存储到azure blob，可以使用cloudAppendblob。以下是演示代码

[FunctionName("TestQueueTrigger")]
public static void Run([QueueTrigger("queueName", Connection = "AzureWebJobsStorage")]string myQueueItem,TraceWriter log)
{

   log.Info($"C# Queue trigger function processed: {myQueueItem}");
   CloudStorageAccount storageAccount = CloudStorageAccount.Parse(CloudConfigurationManager.GetSetting("AzureWebJobsStorage"));
   CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
   CloudBlobContainer container = blobClient.GetContainerReference("mycontainer");

// Create the container if it doesn't already exist.
   container.CreateIfNotExists();

   var appendBlob = container.GetAppendBlobReference("blobName.txt");

   if (!appendBlob.Exists())
   {
        appendBlob.CreateOrReplace();
        appendBlob.AppendText(myQueueItem);
   }
   else
   {
      appendBlob.AppendText($",{myQueueItem}");
   }


 }
