Microsoft.Azure.StorageException: 指定的资源名称包含无效字符

Question

我正在创建 blob 存储以将文件从本地路径加载到云。使用我在门户上创建的存储帐户，我收到一个错误：Microsoft.Azure.Storage.StorageException:The specified resource name contains invalid characters. 这是我想要实现的代码下面的代码。它缺少什么？请指教

嗨，团队有没有人可以帮助我，因为我遇到了这个例外？解决方案中缺少什么？存储帐户已在门户上创建，我正在使用来自门户的连接字符串，容器也已创建。有什么我应该可以添加或修改的吗？这个错误可能是什么原因？我只是想了解它，也许我在我的“connectionString”上调用了无效的名称？或者请为我提供一些关于此的想法，因为我在没有互联网帮助的情况下坚持了近 1 天的时间。反馈可能会受到高度赞赏和指导，谢谢，因为我期待有关此问题的更多详细信息。

Answer 1

似乎您的容器名称或连接字符串错误。

容器名称必须是有效的 DNS 名称，符合以下命名规则： 容器名称必须以字母或数字开头，并且只能包含字母、数字和破折号 (-) 字符。每个破折号 (-) 字符的前后必须紧跟一个字母或数字；容器名称中不允许出现连续的破折号。容器名称中的所有字母都必须小写。容器名称的长度必须为 3 到 63 个字符。

请参考文档 Container naming convention

如果这对任何人都有帮助，我在从 Visual Studio 发布到 Azure 函数时遇到了同样的错误。经过一番摸索，发现在安装过程中自动添加了一个新的函数文件，其中包含以下代码：

[FunctionName("Function")]
public static void Run([BlobTrigger("Path/{name}") ...

一旦我改变了

Path/{name} 部分小写

path/{name}，错误消失了。

我最终删除了这个自动生成的文件，但这表明您不能总是信任自动路由，并进一步证实了 Sajeetharan 的回答。
