我认为,这是一个非常个人的问题,但由于我正在设计如何允许我的网站上的用户名使用结构和特性,我开始思考,我是否太严厉? 什么应该受到限制,什么不是?
这是我的用户名规则:
What is generally a good aspect of the username? Am I too harsh? Am I to stricted? Should I let other characters after spaces, etc.
如果有人感兴趣的话,这是我的reg:
/^(?=.{3,20}$)[a-zA-Z][a-zA-Z0-9_.^]*(?: [a-zA-Z0-9]+)*$/
在进行了一些研究之后,我决定沿用本专题描述的模式。 这就是说“可以接受”。
