Azure Function App 部署后无法删除 Blob 映像

Question

我有一个 Azure Function 应用程序，旨在删除 Azure 存储中的 blob 图像。该函数映射到存储帐户，并且在本地运行时完美运行，指向 Azure 存储帐户。

详情：

• NET版本：.NET 8
• 源代码：C#
• 环境变量：在本地和 Azure 中设置，映射 URL 和存储连接字符串
• 问题：将函数部署到Azure后，无法删除blob映像。在 Azure 中设置的环境变量与在本地执行时设置的环境变量相同。

错误信息：

Exception while executing function: EliminarImagen Could not load file or assembly 'System.Memory.Data, Version=6.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'. The system cannot find the file specified.

我尝试过部署模式设置，将功能设置为

• 依赖框架
• 自给自足

目标运行时间设置为

• win-x64
• 便携式

但总是遇到同样的错误...

这是 .csproj 文件：

<PackageReference Include="Azure.Storage.Blobs" Version="12.22.2" />
<PackageReference Include="Microsoft.NET.Sdk.Functions" Version="4.5.0" />
<PackageReference Include="System.Memory.Data" Version="8.0.1" />

也许我错过了一些东西，但我已经没有想法了，执行删除 blob 的代码是这样的：

using Azure.Storage.Blobs;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Extensions.Http;
using Microsoft.Extensions.Logging;
using System;
using System.Threading.Tasks;

namespace FuncionEliminarImagenes.Clases
 {
    public static class EliminarImagen
    {
        [FunctionName("EliminarImagen")]
         public static async Task<IActionResult> Run(
            [HttpTrigger(AuthorizationLevel.Anonymous, "post", Route = 
"eliminaImagen/{containerName}/{imageName}")] HttpRequest req, string containerName, 
string imageName, ILogger log)
        {
            log.LogInformation("Initializing the function, ready to receive requests...");

        BlobServiceClient blobServiceClient = new BlobServiceClient(Conexion.connectionString);
        BlobContainerClient containerClient = blobServiceClient.GetBlobContainerClient(containerName);

        // Check if container exists
        if (!await containerClient.ExistsAsync())
        {
            log.LogError($"The container {containerName} does not exist.");
            return new NotFoundObjectResult($"The container {containerName} does not exist.");
        }

        BlobClient blobClient = containerClient.GetBlobClient(imageName);
        log.LogInformation($"Attempting to delete the image: {imageName} in the container: {containerName}");

        if (!await blobClient.ExistsAsync())
        {
            log.LogWarning($"The image {imageName} does not exist in the container {containerName}.");
            return new NotFoundObjectResult($"The image {imageName} does not exist in the container {containerName}.");
        }
        else
        {
            var deleteResponse = await blobClient.DeleteIfExistsAsync();
            if (deleteResponse)
            {
                log.LogInformation($"The image {imageName} was deleted from the container {containerName}.");
                return new OkObjectResult($"The image {imageName} was successfully deleted.");
            }
            return new StatusCodeResult(200);
        }
    }
}

}

您需要更新您的函数才能使用 .net 8。我假设您正在使用隔离进程模型。我最近也遇到这个问题了

您需要更新应用程序以使用 Microsoft.Azure.Functions.Worker 包而不是 WebJobs 包。

这篇 MS 文章介绍了如何更新。
