验证Dart中的电子邮件地址？ [英] Validate email address in Dart?

问题描述

根据 RegExp 文档，我们必须使用 JavaScript （ Perl 5 ）正则表达式： ECMA规范。您使用哪种模式进行电子邮件验证？

According to RegExp documentation, we must use JavaScript (Perl 5) regular expressions : ECMA Specification. What pattern do you use for email validation?

推荐答案

我建议每个人都对HTML5电子邮件验证规范进行标准化RFC822禁止使用电子邮件地址的几种很少使用的功能（例如注释！），但是可以被正则表达式识别。

I'd recommend everyone standardize on the HTML5 email validation spec, which differs from RFC822 by disallowing several very seldom-used features of email addresses (like comments!), but can be recognized by regexes.

以下是HTML5规范中有关电子邮件验证的部分：
http://www.whatwg.org/specs/web-apps/current-work/multipage/states-of-the-type-attribute.html#e-mail -state-％28type = email％29

Here's the section on email validation in the HTML5 spec: http://www.whatwg.org/specs/web-apps/current-work/multipage/states-of-the-type-attribute.html#e-mail-state-%28type=email%29

这是正则表达式：

^[a-zA-Z0-9.!#$%&'*+/=?^_`{|}~-]+@[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,253}[a-zA-Z0-9])?(?:\.[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,253}[a-zA-Z0-9])?)*$
