Django打造在线教育平台_day_4： 完成注册与账户激活功能

1、功能分析

　　输入合法验证、验证码生成：form.py

　　注册：views.py

　　发送邮件功能：utils/email_send.py

2、把注册register.html页面复制到templats目录下

3、安装Django验证码生成库

pip install django-simple-captcha=0.4.6

4、输入合法验证、验证码生成form.py

from django import forms
from captcha.fields import CaptchaField  #倒入验证码模块

class RegisterForm(forms.Form):
    """注册用户验证码"""
    email = forms.EmailField(required=True)
    password = forms.CharField(required=True, min_length=8)  # 最小长度8
    captcha = CaptchaField(error_messages={'invalid': u'验证码错误'})  # 自定义错误提示信息

5、在user目录下新建utils文件夹，在文件夹下建立向邮箱发送邮件文件email_send.py，实现注册邮件发送功能：

from random import Random
from django.core.mail import send_mail  #发送邮件模块
from users.models import EmailVerifyRecord
from MxOnline.settings import EMAIL_FROM

def random_str(randomlength=8):
    """生成随机字符串"""
    str = ''
    chars = 'AaBbCcDdEdFfGgHhIiJjKkLlMmNnOoPpQqRrSsTtUuVvWwXxYyZz0123456789'
    length = len(chars) - 1
    random = Random()
    for i in range(randomlength):
        str += chars[random.randint(0,length)]
    return str

def send_register_email(email, send_type='register'):
    email_record = EmailVerifyRecord()
    code = random_str(16)  # 16位长度的字符串
    email_record.code = code
    email_record.email = email
    email_record.send_type = send_type
    email_record.save() #保存

    email_title = ''
    email_body = ''

    if send_type == 'register':
        email_title = '注册激活链接'
        email_body = '请点击链接激活你的账号：http://127.0.0.1:8000/active/{0}'.format(code)

        send_status = send_mail(email_title, email_body, EMAIL_FROM, [email]) # 发送邮件
        if send_status:
            pass

6、在users/views.py文件中实现注册激活

from django.shortcuts import render
from django.views.generic.base import View
from django.contrib.auth.hashers import make_password  # 对密码加密模块

from .models import UserProfile, EmailVerifyRecord
from .forms import RegisterForm
from users.utils.email_send import send_register_email

class RegisterView(View):
    def get(self, request):
        register_form = RegisterForm()
        return render(request, "register.html", {'register_form': register_form})

    def post(self, request):
        register_form = RegisterForm(request.POST)
        if register_form.is_valid():
            user_name = request.POST.get('email', '')
            if UserProfile.objects.filter(email=user_name): # 判断邮箱是否已经存在
                return render(request, "register.html", {'register_form': register_form, 'msg':'用户已经注册'})
            pass_word = request.POST.get('password', '')
            user_profile = UserProfile()
            user_profile.username = user_name
            user_profile.email = user_name
            user_profile.is_active = False # 设置注册的账户没有激活
            user_profile.password = make_password(pass_word) # 对密码加密
            user_profile.save() # 保存数据库

            send_register_email(user_name, 'register')
            return render(request, "login.html")
        else:
            return render(request, "register.html", {'register_form': register_form})


class ActiveUserView(View):
    """账户激活的View"""
    def get(self, request, active_code):
        all_records = EmailVerifyRecord.objects.filter(code=active_code)
        if all_records:
            for record in all_records:
                email = record.email
                user = UserProfile.objects.get(email=email)
                user.is_active = True
                user.save()
        else:
            # active_fail.html在templates中新建的一个文件body中就一个<p>链接失效!</p>
            return render(request, "active_fail.html", {})
        return render(request, "login.html", {})

7、urls.py文件添加代码

from django.conf.urls import url, includefrom django.views.generic import TemplateViewfrom users.views import LoginView, RegisterView, ActiveUserView

urlpatterns = [
    url(r'^register/$', RegisterView.as_view(), name='register'), # 注册
    url(r'^captcha/', include('captcha.urls')), # 验证码
    url(r'^active/(?P<active_code>.*)/$', ActiveUserView.as_view(), name='user_active'), # 配置激活账户链接
]

8、修改index与register.html

<a style="color:white" class="fr registerbtn" href="{% url 'register' %}">注册</a>  # href="{% url 'register' %}"

<!DOCTYPE html>
<html>
{% load staticfiles %} #添加

<link rel="stylesheet" type="text/css" href="{% static 'css/reset.css' %}">
<link rel="stylesheet" type="text/css" href="{% static 'css/login.css' %}">

<li><a href=""><img width="483" height="472" src="{% static 'images/57a801860001c34b12000460.jpg' %}" /></a></li>
<li><a href=""><img width="483" height="472" src="{% static 'images/57a801860001c34b12000460.jpg' %}" /></a></li>

<li><a href=""><img width="483" height="472" src="{% static 'images/57a801860001c34b12000460.jpg' %}" /></a></li>

<script src="{% static 'js/jquery.min.js' %}" type="text/javascript"></script>
<script src="{% static 'js/unslider.js' %}" type="text/javascript"></script>
<script src="{% static 'js/validateDialog.js' %}"  type="text/javascript"></script>
<script src="{% static 'js/login.js' %}"  type="text/javascript"></script>

9、在settings.py中添加captcha，配置发送邮箱

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'users',  # 注册App
    'operation',
    'courses',
    'organization',
    # 添加以下两个app配置
    'xadmin',
    'crispy_forms',
    'captcha',
]

# 邮箱发送者配置
EMAIL_HOST = 'smtp.sina.com'
EMAIL_PORT = 25
EMAIL_HOST_USER = 'qq602906176@sina.com'
EMAIL_HOST_PASSWORD = 'mao228298'
EMAIL_USE_TLS = False
EMAIL_FROM = 'qq602906176@sina.com'

10、Tools->run manage.py Tas生成captcha相关数据表

　　输入：makemigrations

　　输入：migrate

11、register.html

<form id="email_register_form" method="post" action="{% url 'register' %}" autocomplete="off">
........

<div class="form-group marb8 captcha1 ">
    <label>验&nbsp;证&nbsp;码</label>
    {{ register_form.captcha }} #生成验证码输入框与生成验证码图片
    </div>
........
{% csrf_token %}
</form>
<div class="tab-form">

    <form id="email_register_form" method="post" action="{% url 'register' %}" autocomplete="off">
        <div class="form-group marb20 {% if register_form.errors.email %}errorput{% endif %}">
            <label>邮&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;箱</label>
            <input  type="text" id="id_email" name="email" value="{{ register_form.email.value }}" placeholder="请输入您的邮箱地址" />
        </div>
        <div class="form-group marb8 {% if register_form.errors.password %}errorput{% endif %}">
            <label>密&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;码</label>
            <input type="password" id="id_password" name="password"  value="{{ register_form.email.password }}" placeholder="请输入6-20位非中文字符密码" />
        </div>
        <div class="form-group marb8 captcha1 {% if register_form.errors.captcha %}errorput{% endif %}">
            <label>验&nbsp;证&nbsp;码</label>
            {{ register_form.captcha }}
        </div>
        <div class="error btns" id="jsEmailTips">{% for key,error in register_form.errors.items %}{{ error }}{% endfor %}{{ msg }}</div>
        <div class="auto-box marb8">
        </div>
        <input class="btn btn-green" id="jsEmailRegBtn" type="submit" value="注册并登录" />
     {% csrf_token %}
    </form>
