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?发生此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，我将这个问题坚持了近1天.反馈可能会受到高度赞赏和指导，非常感谢，因为我期待着更多有关此问题的详细信息.
Hi Team is there any mate who can help me, as i am getting this exception? What am missing from the solution? The Storage account has been created on portal and i am using connection string from portal, the container has been also created. Is there anything i should be in a position to add or modify? What could be reason for this error? i just want to understand it, maybe i am calling not valid name on my 'connectionString'? Or Kindly please provide me with some idea around this as i am stuck to this problem for close 1 day with no help from internet. Feedback maybe highly appreciated and guidance, thanks as i am looking forward for more details to this problem.
推荐答案
您的容器名称或连接字符串似乎错误.
Seems your Container name or connection string wrong.
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(-)必须紧跟在前面，并在后面加上一个字母或数字；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.
A container name must be a valid DNS name, conforming to the following naming rules: Container names must start with a letter or number, and can contain only letters, numbers, and the dash (-) character. Every dash (-) character must be immediately preceded and followed by a letter or number; consecutive dashes are not permitted in container names. All letters in a container name must be lowercase. Container names must be from 3 through 63 characters long.
请参考 容器命名约定
