使用 DevOps 部署 Azure Function

Question

我已经构建了一个 Azure 函数。我可以直接从 Visual Studio（右键单击项目，然后“发布”）将其部署到我的 Azure FunctionApps，没有任何问题。但是，当我尝试使用 Azure DevOps 构建和部署它时，我收到以下错误，但我不知道这意味着什么。我什至不知道什么是Kudu？

The network path was not found.

我懂了。当我创建 Azure Function App 时，它会动态生成一个存储帐户。我不喜欢这个名称，因此删除了存储帐户并使用新名称创建了一个，但旧删除的存储帐户的连接字符串仍然位于 Azure 门户中 Azure Function 的应用程序设置中。

没有存储，没有 Kudu。没有 Kudu，就无法发布您的应用程序。

检查“WEBSITE_CONTENTAZUREFILECONNECTIONSTRING”应用程序设置是否指向仍然存在的实际存储帐户。
