Azure Web Job 有时无法连接到存储帐户

Question

我们有一个正在运行的 Azure Web 作业（具有 [Singleton] 属性），它偶尔会抱怨无法连接到它需要获取锁的存储帐户，或者当我们尝试登录到存储帐户时。

在网络作业日志中，它会导致“无效的存储帐户 XXXXXX。请确保您的凭据正确。”

我已经仔细检查了存储帐户的访问密钥、AzureWebJobsStorage 和 AzureWebJobsDashboard 的托管 Azure 服务连接字符串中的值，以及我们在尝试创建 CloudTableClient 以进行日志记录时使用的应用程序设置。

这是间歇性的，大约 80% 的时间有效，20% 的时间它会抱怨。

Answer 1

我看到您在尝试打开 Socket 以与 Windows 存储通信时遇到异常。我猜您遇到的间歇性问题是由于遇到了 Azure Web 应用程序的出站连接限制。要解决此问题，请尝试扩大到更高的计划。

Answer 2

检查您是否为您的存储帐户启用了任何 CORS？如果有 CORS，则只能从列入白名单的域访问。

Answer 3

最近，我们的一项网络作业遇到了类似的问题，该作业早些时候运行良好，但突然停止运行。 Web 作业尝试每分钟重新启动一次，但失败并显示错误消息 Invalid storage account ABStorage。请确保您的凭据正确。 Web 作业仍处于等待重新启动状态。经过调查，我们发现存储连接字符串完全没有问题，而 Azure 存储 SDK 中存在一些错误，导致 Azure 门户上针对存储帐户配置的 CORS 规则没有被正确解释。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，使每个域有一个 HTTP 方法，并且 Web 作业能够立即启动。
