Azure Functions blob 输入绑定，没有错误，没有创建文件

Question

我正在尝试让 Azure 函数在 blob 存储上创建一个具有给定文件名的文件。我没有收到任何错误，但文件似乎也没有出现。它在本地或部署时不起作用。

我在设置 blob 存储及其访问方面不是很有经验，我错过了什么？

using System;
using System.IO;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Extensions.Http;
using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.Logging;
using Newtonsoft.Json;

namespace My.Functions
{
    public static class UploadGhost
    {
        [FunctionName("UploadGhost")]
        [StorageAccount("AzureWebJobsStorage")]
        public static async Task<IActionResult> Run(
            [HttpTrigger(AuthorizationLevel.Anonymous, "get", "post", Route = null)] HttpRequest req,
            ILogger log,
            IBinder binder)
        {
        
            string filename = "ghostsdev/myFile.txt";
            var attribute = new BlobAttribute(filename, FileAccess.Write);

            attribute.Connection = "AzureWebJobsStorage";
            using (var writer = await binder.BindAsync<TextWriter>(attribute))
            {
                writer.Write("myData");
                log.LogInformation("I made a file! or did I... ");
            }

            return new OkObjectResult("Executed without errors!");
        }
    }
}

输出：

2021-09-17T17:13:07  Welcome, you are now connected to log-streaming service. The default timeout is 2 hours. Change the timeout with the App Setting SCM_LOGSTREAM_TIMEOUT (in seconds).

编辑：我不知道默认情况下有一个与函数关联的存储帐户，文件出现在那里。

通过对本地计算机 visual studio 2019 中的共享代码进行以下更改并添加“Microsoft.Azure.WebJobs.Extensions.Storage(4.0.5)”依赖项，我们能够在存储中创建一个 blob帐户并在触发 Http 触发器时将数据写入创建的 blob。

这里是示例输出以供参考：
