azure-webjobs - 异常 : An attempt was made to access a socket in a way forbidden by its access permissions

Question

当我将 WebJob 部署到 Azure 时，我收到以下错误消息:

Unhandled Exception: Microsoft.WindowsAzure.Storage.StorageException: An attempt was made to access a socket in a way forbidden by its access permissions

堆栈跟踪无助于查看:

Unhandled Exception: Microsoft.WindowsAzure.Storage.StorageException: An attempt was made to access a socket in a way forbidden by its access permissions ---> System.Net.Http.HttpRequestException: An attempt was made to access a socket in a way forbidden by its access permissions ---> System.Net.Sockets.SocketException: An attempt was made to access a socket in a way forbidden by its access permissions

任何人都知道什么可以解决这个问题？

我最近遇到了同样的问题。
当其功能无法正确加载其触发器时，Webjobs 会出错。

与函数相反，当绑定(bind)失败时，Webjobs 真的不太会谈论到底出了什么问题。

我会检查以下内容:

确保在您的 appsettings、Azure Config 或 Keyvault(或存储连接字符串的任何位置)中定义了连接字符串

确保连接字符串名为“AzureWebJobsStorage”作为默认属性 (QueueTrigger) 仅限 在配置

中查找该特定键

确保连接字符串实际上指向允许您的 webjob 访问的存储(例如，不要将您的开发订阅指向您的 qa 环境，这是我的错误)
