例外：尝试以访问权限禁止的方式访问套接字

Question

当我将 WebJob 部署到 Azure 时，我收到以下错误消息：

未处理的异常：Microsoft.WindowsAzure.Storage.StorageException：尝试以访问权限禁止的方式访问套接字

堆栈跟踪也无济于事：

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 Webjobs 的函数无法正确加载触发器时，它们会出错。

与函数相反，Webjobs 对绑定失败时究竟出了什么问题并不十分健谈。

我会检查以下内容：

• 确保在应用设置、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”，因为默认属性 (QueueTrigger)仅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）
