使用 .NET Core 2 的 Azure WebJobs 失败 "Invalid storage account"
Azure WebJobs using .NET Core 2 failing with "Invalid storage account"
按照 Matt Roberts 出色的分步文章 Azure WebJobs in .NET Core 2 (with DI and configuration) 我创建了一个部署没有问题的解决方案（使用 Visual Studio 2017），但失败并出现 "Invalid storage account" 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)'.
我可以看到必须选择 AzureWebJobsDashboard 和 AzureWebJobsStorage 环境变量，因为错误明确命名了连接字符串中使用的 AccountName。
我尝试了存储连接字符串的两种变体，结果相同：
DefaultEndpointsProtocol=https;AccountName=mywebjobsstorage;AccountKey=********
DefaultEndpointsProtocol=https;AccountName=mywebjobsstorage;AccountKey=********;EndpointSuffix=core.windows.net
知道问题出在哪里吗？

我们最近遇到了与我们的一项网络作业类似的问题，该作业早些时候运行良好但突然停止工作。 Web 作业尝试每分钟重新启动一次，但失败并显示错误消息 无效存储帐户 ABStorage。请确保您的凭据正确无误。 Web 作业仍处于 Pending Restart 状态。经过调查，我们发现存储连接字符串完全正常，而 Azure 存储 SDK 中存在一些错误，导致在 Azure 门户上针对存储帐户配置的 CORS 规则未被正确解释。在 Azure 门户中，我们在 Azure 存储上只有 1 个 CORS 规则，并选择了所有允许的 HTTP 方法。
我们更新了存储帐户上的 CORS 规则，使每个域具有一个 HTTP 方法，并且 Web 作业能够立即启动。
