空的string值""是string类型的有效值，因此它是具有string作为键类型的映射的有效键值。在这方面没有什么“边缘”情况。
是否有意义存储与空字符串键相关联的值取决于您的用例。这没有好坏之分。如果对您有意义，请使用它。
英文:
The empty string value "" is a valid value for the string type, so it's a valid key value for maps having string as the key type. There's nothing "edge" case in that.
Whether it makes sense to store a value associated with the empty string key really depends on your use case. There's nothing good or bad in it. Use it if it has meaning for you.
