在Django后端仔细检查电子邮件验证

Question

考虑到用户可以在浏览器中禁用JavaScript，我该如何在 Django 后端进行“双重检查”以进行电子邮件验证（具体来说，是为了防止使用Webmail [GMail注册] ，Hotmail等]）？谢谢。

Answer 1

您可以在您的forms.py（必须创建该文件）应用中执行此操作

from django import forms

class ContactForm(forms.Form):
    full_name = forms.CharField()
    email = forms.EmailField()

    def clean_email(self, *args, **kwargs):
        email = self.cleaned_data.get('email')
        if email.endswith('@gmail.com'):  # etc.
            raise forms.ValidationError('This is not a valid email')
        return email
