使用.NET Core 2的Azure WebJobs失败并显示“Invalid storage account”

标签： c# azure .net-core azure-storage azure-webjobs

按照Matt Roberts的优秀分步文章Azure WebJobs in .NET Core 2 (with DI and configuration)，我创建了一个无问题部署的解决方案（使用Visual Studio 2017），但失败并出现“无效存储帐户”异常：

Unhandled Exception: System.InvalidOperationException: Invalid storage account 'mywebjobsstorage'. Please make sure your credentials are correct. ---> System.MissingMethodException: Method not found: 'System.Threading.Tasks.Task`1<Microsoft.WindowsAzure.Storage.Shared.Protocol.ServiceProperties> Microsoft.WindowsAzure.Storage.Blob.CloudBlobClient.GetServicePropertiesAsync(System.Threading.CancellationToken)'.

我可以看到AzureWebJobsDashboard和AzureWebJobsStorage环境变量必须被选中，因为错误明确指出了连接字符串中使用的AccountName。

我尝试了两种带有相同结果的存储连接字符串的变体：

DefaultEndpointsProtocol=https;AccountName=mywebjobsstorage;AccountKey=********

DefaultEndpointsProtocol=https;AccountName=mywebjobsstorage;AccountKey=********;EndpointSuffix=core.windows.net

任何想法可能是什么问题？

这是完整的异常日志，如果它包含任何其他线索，或者我被误导：

答案 0 :(得分：1)

看起来这些NuGet包中都有一个错误：

  • Microsoft.Azure.WebJobs
  • Microsoft.Azure.WebJobs.Extensions

我使用的是这些软件包的v2.2.0，但它们似乎有一个bug。将这些替换为NuGet包的v3 beta预发行版而不进行任何代码更改解决了这个问题。

<强>更新

.NET Core上仅支持v3 + - https://github.com/Azure/azure-webjobs-sdk/issues/1649#issuecomment-377633805
