Azure blob 触发器没有触发？

Question

我定义了一个简单的 azure blob 存储触发器并将其部署到 azure。我希望它在名为“mycontainer”的 blob 存储容器中上传文件时进行记录。

在配置设置中，我在名为“AzureWebJobsStorage”的设置中添加了存储帐户连接字符串的值。

要查看日志，我转到监控 > 日志 > 文件系统日志。之后，我将两个文件上传到我的 blob 存储帐户，希望显示名称和字节数，但没有成功。我需要配置其他东西才能让它工作吗？是否有其他地方我可以检查以确保函数正在监听存储容器？

这是我的 azure 函数 blob 触发器。

using System;
using System.IO;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Host;
using Microsoft.Extensions.Logging;

namespace resume
{
    public static class MyApp
    {
        [FunctionName("MyApp")]
        public static void Run([BlobTrigger("mycontainer/{name}", Connection = "AzureWebJobsStorage")]Stream myBlob, string name, ILogger log)
        {
            log.LogInformation($"C# Blob trigger function Processed blob\n Name: {name} \n Size: {myBlob.Length} Bytes");
        }
    }
}

我还注意到我在实时指标中出现异常，出现以下错误：

Answer 1

我认为这可能是由以下几点引起的：

仔细检查您的存储连接字符串并确保它有效（且完整）。
确保您指向的存储帐户不是“BlobStorage”类型（使用通用 (V2)。我听说非通用存储帐户不适用于触发器。

如果不是这两个问题，您使用的是哪个版本的 Functions？
