Azure Function App v4 + .NET 6.0（处理中）+ Blob 绑定（未触发）= 无法将 Blob 绑定到类型错误

Question

即使在 hello world 函数中，我也无法使此组合正常工作。我想要一个消耗 table 和 blob 的函数，但不是作为触发器（触发器是计时器）。

当我在本地运行函数应用程序时，我得到

Microsoft.Azure.WebJobs.Host: Error indexing method 'Function1'. Microsoft.Azure.WebJobs.Host: Can't bind Blob to type 'Microsoft.WindowsAzure.Storage.Blob.CloudBlobContainer'.
Possible causes:
 1) Tried binding to 'Azure.Storage.Blobs.BlobContainerClient, Azure.Storage.Blobs, Version=12.10.0.0, Culture=neutral, PublicKeyToken=92742159e12e44c8' but user type assembly was 'Microsoft.WindowsAzure.Storage.Blob.CloudBlobContainer, Microsoft.WindowsAzure.Storage, Version=9.3.1.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35.

 5) Tried binding to 'Azure.Storage.Blobs.Specialized.PageBlobClient, Azure.Storage.Blobs, Version=12.10.0.0, Culture=neutral, PublicKeyToken=92742159e12e44c8' but user type assembly was 'Microsoft.WindowsAzure.Storage.Blob.CloudBlobContainer, Microsoft.WindowsAzure.Storage, Version=9.3.1.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35.

为了创建这个，我做了以下操作：

正在使用 .NET 6.0 创建新的函数应用程序项目
创建了以下函数：

using System;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Host;
using Microsoft.Extensions.Logging;
using Microsoft.WindowsAzure.Storage.Blob;
using Microsoft.WindowsAzure.Storage.Table;

namespace FunctionApp1
{
    public class Function1
    {
        [FunctionName("Function1")]
        public void Run(
            [TimerTrigger("0 */5 * * * *")] TimerInfo myTimer,
            [Blob("activity-events", Connection = "StorageAccountBlobEndpoint")] CloudBlobContainer cloudBlobContainer,
            ILogger log

        )
        {
            log.LogInformation($"C# Timer trigger function executed at: {DateTime.Now}");
        }
    }
}

完整的 CSPROJ 是

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>
    <AzureFunctionsVersion>v4</AzureFunctionsVersion>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.Azure.WebJobs.Extensions.Storage" Version="4.0.5" />
    <PackageReference Include="Microsoft.NET.Sdk.Functions" Version="4.1.0" />
  </ItemGroup>
  <ItemGroup>
    <None Update="host.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
    <None Update="local.settings.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
      <CopyToPublishDirectory>Never</CopyToPublishDirectory>
    </None>
  </ItemGroup>
</Project>

我将来也想有一个 table 绑定，我知道这会排除 Microsoft.Azure.WebJobs.Extensions.Storage 的 V 5.X。

我可能遗漏了一些基本的东西，但如果有人能识别我将不胜感激。

Answer 1

由于您的 input/trigger 绑定是一个计时器，您是否正在查看 blob 和 table 输出绑定？

看看这个文档：https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-storage-blob-output?tabs=in-process%2Cextensionv5&pivots=programming-language-csharp

我相信一些事情：

            public class Function1
{
    [FunctionName("Function1")]
    public void Run([TimerTrigger("0 */5 * * * *")]TimerInfo myTimer, 
        [Blob("activity-events", FileAccess.Write, Connection = "MyBlobConnString")] out Stream myblob,
        ILogger log)
    {
        log.LogInformation($"C# Timer trigger function executed at: {DateTime.Now}");

        //DO SOMETHING WITH myBlob before function exits
    }
}

Answer 2

好吧，正如预期的那样，它似乎相当简单 - 我没有从 Microsoft.WindowsAzure.Storage.Blob 引用 CloudBlobContainer，而是从 Microsoft.Azure.Cosmos.Table.[=13= 引用它]

旁注：这打开了一个巨大的潘多拉魔盒，里面装满了我现在需要在这个现有解决方案中修复的其他东西。
