使用正则表达式进行验证电子邮件很棘手

Using regular expression to validate emails is tricky

尝试以下电子邮件作为正则表达式的输入，即： ^ [\w .-] + @ [A-Za -z0-9 .-] + \。[A-Za-z] {2,6} $

Try the following email as an input to your regex ie:^[\w.-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,6}$

abc @ b ... com

如果您是针对某个应用执行此操作，则可以通过向提供的地址发送电子邮件来使用电子邮件验证，而不要使用非常复杂的正则表达式。

If you are doing this for an app then use email validation by sending an email to the address provided rather than using very complex regex.
