使用.NET Core 2的Azure WebJob失败，并显示“无效的存储帐户”。

本文介绍了使用.NET Core 2的Azure WebJob失败，并显示“无效的存储帐户”。的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

马特·罗伯茨（Matt Roberts）出色的循序渐进文章。NET Core 2中的Azure WebJobs（具有DI和配置）我创建了一个解决方案，该解决方案的部署没有问题（使用Visual Studio 2017），但是失败并出现无效的存储帐户异常：

Following Matt Roberts excellent step-by-step article Azure WebJobs in .NET Core 2 (with DI and configuration) I've created a solution that deploys without issue (using Visual Studio 2017), but fails with a "Invalid storage account" exception:

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)'.

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

I can see that the AzureWebJobsDashboard and AzureWebJobsStorage environment variables must be getting picked up as the error explicitly names the AccountName used in the connection string.

我尝试使用存储连接字符串进行两种变体，结果相同：

I've tried two variations with the storage connection string with the same result:

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

任何想法可能是什么问题？

Any ideas what the issue might be?

以下是完整的异常日志，以防它包含任何其他线索，或者我被误导了：

推荐答案

在这些NuGet软件包中似乎都存在一个错误：

It looks like there was either a bug in either of these NuGet packages:

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

我正在使用这些软件包的v2.2.0，但它们似乎具有一个错误。将这些交换为NuGet软件包的v3 beta预发行版本，无需任何代码更改即可解决此问题。

I was using v2.2.0 of these packages, but they appear to have a bug. Swapping these for v3 beta pre-releases of the NuGet packages without any code changes resolved the issue.

更新

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

Only v3+ is supported on .NET Core - github/Azure/azure-webjobs-sdk/issues/1649#issuecomment-377633805
