django 通过ajax完成邮箱用户注册、激活账号

一、图片验证码

django-simple-captcha配置

1.在pycharm中，File====》Settings====》Project:项目名====》Project Interpreter====》+====》搜django-simple-captcha　　选择0.55以上版本，然后点install package 按钮进行安装

2.项目名/urls.py中添加代码：

from django.urls import path,include
......

from users.views import IndexView
......

urlpatterns = [
    ......
    
    #配置验证码

    path('captcha/',include('captcha.urls')),
    #首页url
    path('', IndexView.as_view(), name='index'),

    ......
]

3.settings.py中添加一个注册信息

INSTALLED_APPS = [

        ......
    
    'captcha'
]

4.打开终端Terminal执行更新数据库命令：

python manage.py makemigrations
python manage.py migrate

5.在users目录下新建form.py文件：

from django import forms
from captcha.fields import CaptchaField
......


class RegisterForm(forms.Form):
    """注册信息的验证"""

    ......

    captcha=CaptchaField(error_messages={'invalid':'验证码错误'})

   ......

 6.在users/views.py中添加代码：

from users.form import RegisterForm


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

7.在前端首页index.html中显示验证码、输入框

html

<div class="modal fade" id="register" tabindex="-1" role="dialog">

    ......

<!--模态框中关于注册的内容start-->
      <div class="modal-body">
        ......
            
            <P><div style="display: inline-block;100px;text-align: center"><b >验证码：</b></div>

<!--验证码start-->

            <div class="cap">{{ register_form.captcha }}</div>

<!--验证码end-->

</P>
            {% csrf_token %}
        </form>
          <p><div style="margin-left: 100px;background-color: orangered;150px;text-align: center"><b></b></div></p>
      </div>

<!--模态框中关于注册的内容end-->

    ......

css

<style>
    .cap{
        display: inline-block;
        width: 280px;
        height: 36px;
    }
    .cap img{
        float: right;
    }
</style>

js 跟刷新验证码相关（需要先引入jQuery）

$(function(){
        $('.captcha').css({
        'cursor': 'pointer'
    });
    /*# ajax 刷新*/
        $('.captcha').click(function(){
            console.log('click');
            $.getJSON("/captcha/refresh/",function(result){
                $('.captcha').attr('src', result['image_url']);
                $('#id_captcha_0').val(result['key'])
            });
        });
    })

二、ajax邮箱注册

 1.在前端跟注册绑定的模态框代码写成：

html

<div class="modal fade" id="register" tabindex="-1" role="dialog">

  ......
      
      <div class="modal-body">
        <form id="registerform" action="#" method="post">
            <p>
                <div class="re-input"><b>用户名：</b></div>
                <input type="text" name="user" placeholder="用户名">
                <div class="msg"><b id="user-msg"></b></div>
            </p>
            <p>
                <div class="re-input"><b>邮箱：</b></div>
                <input type="text" name="email" placeholder="邮箱">
                <div class="msg"><b id="email-msg">2222</b></div>
            </p>
            <p>
                <div class="re-input"><b >密码：</b></div>
                <input type="password" name="pwd" placeholder="密码（不少于6位）">
                <div class="msg"><b id="pwd-msg">222</b></div>
            </p>
            <p>
                <div class="re-input"><b >确认密码：</b></div>
                <input type="password" name="pwd2" placeholder="确认密码">
                <div class="msg"><b id="pwd-msg2">22</b></div>
            </p>
            <P><div class="re-input"><b >验证码：</b></div>
                <div class="cap">{{ register_form.captcha }}</div>
                <div class="msg"><b id="captcha-msg">2</b></div>
            </P>
            {% csrf_token %}
        </form>
          <p><div style="margin-left: 100px;color: white;background-color: green;180px;text-align: center"><b id="active-msg"></b></div></p>

      ......

        <button type="button" class="btn btn-primary" id="registerbtn">确认注册</button>

      ......

css

<style>
    .cap{
        display: inline-block;
        width: 280px;
        height: 36px;
    }
    .cap img{
        float: right;
    }
    .re-input{
        display: inline-block;
        width:100px;
        text-align: center
    }
    .msg{
        margin-left: 100px;
        background-color: orangered;
        width:180px;
        text-align: center
    }
</style>

跟ajax注册相关的js代码：

$("#registerbtn").click(function() {
        $.ajax({
            cache:false,
            type:"POST",
            url:"{% url 'users:register' %}",
            dataType:'json',
            data:$('#registerform').serialize(),
            //通过id找到提交form表单，并将表单转成字符串
            async:true,
            //异步为真，ajax提交的过程中，同时可以做其他的操作
            success:function (data) {
                //jquery3以后，会将回传过来的字符串格式的data自动json解析不用再使用一遍JSON.parse(data)了，不然反而会在控制台报错
                if(data.status){
                    $('#active-msg').html(data.status);

                } else{
                    if(data.user){
                        username_msg=data.user.toString();
                        $('#user-msg').html('用户名'+ username_msg);
                    }
                    if(data.email){
                        email_msg=data.email.toString();
                        $('#email-msg').html('邮箱'+ email_msg);
                    }
                    if(data.pwd){
                        password_msg=data.pwd.toString();
                        $('#pwd-msg').html('密码'+ password_msg);
                    }
                    if(data.captcha){
                        captcha_msg=data.captcha.toString();
                        $('#captcha-msg').html(captcha_msg);
                    }
                    msg=data.__all__.toString();
                    $('#active-msg').html(msg);

                }
            }
        });
    });

提升用户交互体验的js代码：

$("input").bind('input propertychange', function() {
        $('#login-fail').html('');
        $('#user-msg').html('');
        $('#email-msg').html('');
        $('#pwd-msg').html('');
        $('#pwd-msg2').html('');
        $('#captcha-msg').html('');
    });

2.users/form.py代码：（要验证的字段名跟前端input框的name值要保持一致！）

from django import forms
from captcha.fields import CaptchaField
from .models import UserProfile


class RegisterForm(forms.Form):
    """注册信息的验证"""
    user = forms.CharField(required=True, error_messages={'required': '用户名不能为空.'})
    email=forms.EmailField(required=True,error_messages={'required': '邮箱不能为空.'})
    pwd = forms.CharField(required=True,
                          min_length=6,
                          error_messages={'required': '密码不能为空.', 'min_length': "至少6位"})
    pwd2 = forms.CharField(required=True,
                          min_length=6,
                          error_messages={'required': '密码不能为空.', 'min_length': "至少6位"})
    captcha=CaptchaField(error_messages={'invalid':'验证码错误'})

    def clean(self):
        '''验证两次密码是否一致'''
        p1=self.cleaned_data.get('pwd')
        p2=self.cleaned_data.get('pwd2')
        if p1!=p2:
            raise forms.ValidationError('两次输入密码不一致')
        else:
            return self.cleaned_data

3.users/views.py中与注册相关的代码：

......

from django.http import HttpResponse
from .models import UserProfile,ShopProfile
from users.form import RegisterForm
from django.contrib.auth.hashers import make_password
import json

class RegisterView(View):
    """邮箱注册"""
    def post(self, request):
        register_form=RegisterForm(request.POST)
        if register_form.is_valid():
            user_name=request.POST.get('user','')
            email=request.POST.get('email','')
            pass_word=request.POST.get('pwd','')
            u=UserProfile.objects.filter(username=user_name).count()
            e=UserProfile.objects.filter(email=email).count()
            if u or e:
                return HttpResponse('{"status":"该用户名或邮箱已被占用！"}')
            else:
                user_profile=UserProfile()
                user_profile.username=user_name
                user_profile.email=email
                user_profile.password=make_password(pass_word)
                user_profile.is_active=False
                user_profile.save()
                return  HttpResponse('{"status":"注册成功请去邮箱激活！"}')
        msg=register_form.errors
        msg=json.dumps(msg)
        return HttpResponse(msg)

4.配置users/urls.py注册路由：

......

from .views import RegisterView
.....

urlpatterns = [

    ......

    path('register/',RegisterView.as_view(),name='register'),

    ......
    ]

三、邮箱激活已注册的账号：

1.新建个数据表存放邮箱激活码：

在users/models.py中增加代码：

class EmailVerifyRecord(models.Model):
    """邮箱激活码"""
    code=models.CharField(max_length=20,verbose_name='验证码')
    email=models.EmailField(max_length=50,verbose_name='邮箱')
    send_type=models.CharField(verbose_name='验证码类型',choices=(('register','注册'),('forget','忘记密码')),
                               max_length=20)
    send_time=models.DateTimeField(verbose_name='发送时间',default=datetime.now)
    class Meta:
        verbose_name='邮箱验证码'
        verbose_name_plural=verbose_name
    def __str__(self):
        return '{0}({1})'.format(self.code,self.email)

在users/adminx.py中注册数据表：

......

from .models import EmailVerifyRecord

......

class EmailVerifyRecordAdmin(object):
    list_display = ['code', 'email', 'send_type', 'send_time']
    search_fields = ['code', 'email', 'send_type']
    list_filter = ['code', 'email', 'send_type', 'send_time']

......

xadmin.site.register(EmailVerifyRecord,EmailVerifyRecordAdmin)

打开终端Terminal执行更新数据库命令：

python manage.py makemigrations
python manage.py migrate

2.写发邮件的脚本：在apps/users/新建utils/email_send.py

from random import Random
from users.models import EmailVerifyRecord
from django.core.mail import send_mail
from xyw.settings import EMAIL_FROM


def random_str(randomlength=8):
    str=''
    chars='AaBbCcDdEeFfGgHhIiJjKkLlMmNnOoPpQqRrSsTtUuVvWwXxYyZz0123456789'
    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)
    email_record.code=code
    email_record.email=email
    email_record.send_type=send_type
    email_record.save()

    email_title=''
    email_body=''

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

        send_status=send_mail(email_title,email_body,EMAIL_FROM,[email])
        if send_status:
            pass
    elif send_type=='forget':
        email_title = '雪易密码重置链接'
        email_body = '请点击下面的链接重置你的密码：http://127.0.0.1:8000/reset/{0}'.format(code)

        send_status = send_mail(email_title, email_body, EMAIL_FROM, [email])
        if send_status:
            pass

3.在settings.py中追加发送邮件的配置代码：

EMAIL_HOST='smtp.sina.cn'
EMAIL_PORT=25
EMAIL_HOST_USER='xxxxxxxx@sina.cn' #你的邮箱
EMAIL_HOST_PASSWORD='********'
EMAIL_USE_TLS=False
EMAIL_FROM='xxxxxxx1@sina.cn' #同样是你的邮箱，跟上面都是发信者邮箱
#我用的新浪的，也可以用别的

4.开启新浪邮箱的smtp服务，不然不能自动发邮件的，步骤如下：

登录新浪邮箱====》设置区====》客户端pop/imp/smtp====》Pop3/SMTP服务====》服务状态：开启====》保存

5.增加激活功能

在users/views.py中增加激活类ActiveUserView(View)代码：

......

from .models import EmailVerifyRecord


......

class ActiveUserView(View):
    """激活账户"""
    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()
            
        return render(request,'index.html')

6.在users/views.py中

对注册类 RegisterView(View)增加发送激活邮件的代码：

......
from apps.utils.email_send import send_register_email


......

class RegisterView(View):
    """邮箱注册"""
    def post(self, request):
   ......
    user_profile.save()

#发送邮件代码start
    send_register_email(email,'register')
#发送邮件代码end

    return  HttpResponse('{"status":"注册成功请去邮箱激活！"}')

对登录LoginView(View)增加验证账户激活与否的代码：

class LoginView(View):
    """用户登录"""
    def post(self,request):
        user_name=request.POST.get("username","")
        pass_word=request.POST.get("pwd","")
        user=authenticate(username=user_name,password=pass_word)
        if user is not None:

#验证账户是否已经激活start
            if user.is_active:
                login(request,user)
                return HttpResponse('{"status":"success"}')
            else:
                return HttpResponse('{"status":"fail","msg":"账户未激活"}')

#验证账户是否已经激活end

        else:
            return HttpResponse('{"status":"fail","msg":"用户名或密码错误"}')

　　至此完成了用邮箱注册及激活，很多时候，激活邮件都会被邮箱自动放入垃圾箱，而且从邮件点击激活链接的时候，还会被提示一些警告信息，可以说通过邮箱注册各种不如通过短信注册，但是……省钱啊！^_^
