我正在创建Blob存储,以将文件从本地路径加载到云。使用我在门户网站上创建的存储帐户,出现错误:Microsoft.Azure.Storage.StorageException:The specified resource name contains invalid characters
。这是我想要实现的代码。它缺少什么?请指教

嗨,有队友可以帮助我,因为我遇到这种情况?解决方案缺少什么?已在门户网站上创建了存储帐户,并且我正在使用门户网站上的连接字符串,还创建了容器。我应该添加或修改任何内容吗?该错误的原因可能是什么?我只是想了解它,也许我在'connectionString'上打了无效的名字?或者,请为我提供一些有关此问题的想法,因为在没有互联网帮助的情况下,我在接近1天的时间内一直被这个问题困扰。反馈可能会受到高度赞赏和指导,非常感谢,因为我期待着有关此问题的更多详细信息。

如果这对任何人有帮助,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}
部分为小写
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。

您的容器名称或连接字符串似乎错误。
上的文档容器名称必须是有效的DNS名称,符合以下要求 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。每一个 破折号(-)必须紧接在前面,并在其后 字母或数字;容器中不允许连续的破折号 名称。容器名称中的所有字母都必须小写。容器 名称必须在3到63个字符之间。
