在 WTForms 中验证美国 phone 号码

Question

我正在使用烧瓶应用程序并使用 wtforms:

class RegisterForm(Form):
    username = StringField('Username', validators=[DataRequired(), Length(min=3, max=25)])
    email = StringField('Email', validators=[DataRequired(), Email(), Length(min=6, max=40)])
    phone = StringField('Phone', validators=[DataRequired(), Length(10)])

我刚刚添加了 phone，正在寻找一种方法来验证美国号码。我遇到了 http://wtforms-components.readthedocs.org/en/stable/#phonenumberfield，但这似乎不再有 phonenumberfield。使用 wtfforms 处理此问题的最佳方法是什么？

已编辑 class：

class RegisterForm(Form):
    username = StringField('Username', validators=[DataRequired(), Length(min=3, max=25)])
    email = StringField('Email', validators=[DataRequired(), Email(), Length(min=6, max=40)])
    phone = StringField('Phone', validators=[DataRequired(),validate_phone('RegisterForm','phone'), Length(min=6, max=40)])

    def validate_phone(form, field):
        if len(field.data) > 16:
            raise ValidationError('Invalid phone number.')
        try:
            input_number = phonenumbers.parse(field.data)
            if not (phonenumbers.is_valid_number(input_number)):
                raise ValidationError('Invalid phone number.')
        except:
            input_number = phonenumbers.parse("+1"+field.data)
            if not (phonenumbers.is_valid_number(input_number)):
                raise ValidationError('Invalid phone number.')

我在最近的申请中使用了python-phonenumbers。它使用 google phone 数字解析的东西。以下是我的使用方法：

from wtforms import ValidationError
import phonenumbers

class RegisterForm(Form):
    username = StringField('Username', validators=[DataRequired(), Length(min=3, max=25)])
    email = StringField('Email', validators=[DataRequired(), Email(), Length(min=6, max=40)])
    phone = StringField('Phone', validators=[DataRequired()])

    def validate_phone(form, field):
        if len(field.data) > 16:
            raise ValidationError('Invalid phone number.')
        try:
            input_number = phonenumbers.parse(field.data)
            if not (phonenumbers.is_valid_number(input_number)):
                raise ValidationError('Invalid phone number.')
        except:
            input_number = phonenumbers.parse("+1"+field.data)
            if not (phonenumbers.is_valid_number(input_number)):
                raise ValidationError('Invalid phone number.')

我在 wtforms 组件中使用了内置的 PhoneNumberField。这是我的使用方法。

from wtforms_components import PhoneNumberField

class UserForm(Form):
    phone_number = PhoneNumberField(
        country_code='US'
        display_format='national'
    )
