猫鼬-验证电子邮件语法

问题描述

我有一个用于用户的猫鼬模式(UserSchema)，我想验证电子邮件是否具有正确的语法.我当前使用的验证如下:

I have a mongoose schema for users (UserSchema) and I'd like to validate whether the email has the right syntax. The validation that I currently use is the following:

UserSchema.path('email').validate(function (email) {
  return email.length
}, 'The e-mail field cannot be empty.')

但是，这只会检查该字段是否为空，而不检查语法.

However, this only checks if the field is empty or not, and not for the syntax.

是否已经存在一些我可以重复使用的东西，或者我必须提出自己的方法并在validate函数中调用它?

Does something already exist that I could re-use or would I have to come up with my own method and call that inside the validate function?

推荐答案

您可以使用正则表达式.看看这个问题:使用JavaScript验证电子邮件地址吗?

You can use a regex. Take a look at this question: Validate email address in JavaScript?

我过去曾经使用过.

UserSchema.path('email').validate(function (email) {
   var emailRegex = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/;
   return emailRegex.test(email.text); // Assuming email has a text attribute
}, 'The e-mail field cannot be empty.')
