有效的电子邮件地址正则表达式? [英] Valid email address regular expression?

问题描述

我已经做了一些测试，但我想问问是否有人发现这个用于电子邮件验证的 ruby​​ 正则表达式有问题:

I have done some testing but I wanted to ask if anyone sees a problem with this ruby regular expression for email validation:

/A([^@s]+)@((?:[-a-z0-9]+.)+[a-z]{2,})/i

好看吗?

推荐答案

你已经很接近了，只需要再添加几个字符:

You were close, have to add just a few more characters:
