在django / python中检查电子邮件的有效性

这是

django.core.validators

class EmailValidator(RegexValidator):    def __call__(self, value):        try: super(EmailValidator, self).__call__(value)        except ValidationError, e: # Trivial case failed. Try for possible IDN domain-part if value and u'@' in value:     parts = value.split(u'@')     domain_part = parts[-1]     try:         parts[-1] = parts[-1].enpre('idna')     except UnipreError:         raise e     super(EmailValidator, self).__call__(u'@'.join(parts)) else:     raiseemail_re = re.compile(    r"(^[-!#$%&'*+/=?^_`{}|~0-9A-Z]+(.[-!#$%&'*+/=?^_`{}|~0-9A-Z]+)*"  # dot-atom    r'|^"([01-10131416-37!#-[]-177]|\[01-011131416-177])*"' # quoted-string    r')@(?:[A-Z0-9](?:[A-Z0-9-]{0,61}[A-Z0-9])?.)+[A-Z]{2,6}.?$', re.IGNORECASE)  # domainvalidate_email = EmailValidator(email_re, _(u'Enter a valid e-mail address.'), 'invalid')

因此，如果你不想使用表单和表单字段，则可以

email_re

validate_email

ValidationError

def validateEmail( email ):    from django.core.validators import validate_email    from django.core.exceptions import ValidationError    try:        validate_email( email )        return True    except ValidationError:        return False
