一百零六：CMS系统之修改邮箱功能完成

这里采用把验证码放到memcached中，所以封装一个memcached的操作

import memcache

cache = memcache.Client(['127.0.0.1:11211'], debug=True)


def set(key, value, timeout=60):
    return cache.set(key, value, timeout)


def get(key):
    return cache.get(key)


def delete(key):
    return cache.delete(key)

form验证

from wtforms import StringField, IntegerField
from wtforms.validators import Email, InputRequired, Length, EqualTo, ValidationError
from flask import g

from ..forms import BaseForm
from utils import cmscache


class ResetEmailForm(BaseForm):
    email = StringField(validators=[InputRequired(message='请输入邮箱'), Email(message='邮箱格式错误')])
    captcha = StringField(validators=[Length(6, 6, message='验证码长度错误')])

    def validate_email(self, field):
        if field.data == g.cms_user.email:
            raise ValidationError('要修改的邮箱为当前使用的邮箱')

    def validate_captcha(self, field):
        captcha = field.data
        email = self.email.data
        captcha_cache = cmscache.get(email)
        if not captcha_cache or captcha.lower() != captcha_cache.lower():
            raise ValidationError('邮箱验证码错误')

$(function () {
    $('#submit').click(function (event) {
        event.preventDefault();
        var emailElement = $('input[name="email"]');
        var captchaElement = $('input[name="captcha"]');

        var email = emailElement.val();
        var captcha = captchaElement.val();
        http.post({
            'url': '/cms/resetemail/',
            'data': {
                'email': email,
                'captcha': captcha
            },
            'success': function (data) {
                if(data['code'] == 200){
                    xtalert.alertSuccessToast('修改邮箱成功');
                    emailElement.val('');
                    captchaElement.val('');
                }else{
                    xtalert.alertInfo(data['message']);
                }
            },
            'fail': function (error) {
                xtalert.alertNetworkError();
            }
        })
    });
});

视图

class ResetEmailView(views.MethodView):
    decorators = [login_required]

    def get(self):
        return render_template('cms/cms_resetemail.html')

    def post(self):
        form = ResetEmailForm(request.form)
        if form.validate():
            g.cms_user.email = form.email.data
            db.session.commit()
            return restful.success()
        else:
            return restful.params_error(form.get_error())
