五、用户注册

主要实现功能

用户输入邮箱、密码和验证码，点注册按钮
如果输入的不正确，提示错误信息
如果正确，发送激活邮件，用户通过邮件激活后才能登陆
即使注册成功，没有激活的用户也不能登陆

5.1.初步视图

users/views.py

class RegisterView(View):
    '''用户注册'''
    def get(self,request):
        return render(request,'register.html')

用户以get方式，直接返回注册页面

5.2.路由设计

# MxOnline/urls.py

from users.views import RegisterView


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

urls中。通过类的as_view方法，调用这个View类

5.3.模板修改

修改index.html

点 “注册 ”应该跳到用户注册页面

 <a style="color:white" class="fr registerbtn" href="/register/">注册</a>

 <a style="color:white" class="fr loginbtn" href="/login/">登录</a>

修改register.html中的静态文件地址

{% load staticfiles %}

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

.
.
.

<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>

测试一下从index界面点注册能不能跳到register界面

5.4.验证码

验证码库：django-simple-captcha，这里面有介绍这个第三方库的使用方法

安装：

pip install  django-simple-captcha

Add captcha to the INSTALLED_APPS in your settings.py

INSTALLED_APPS = [
    'captcha',
]

Add an entry to your urls.py:

urlpatterns = [
    path('captcha/',include('captcha.urls')),
]

生成到数据库

python manage.py makemigrations

python manage.py migrate

可以看到数据库多了一张表

在注册页面显示验证码

定义我们的register form:

# users/forms.py

from captcha.fields import CaptchaField

class RegisterForm(forms.Form):
    '''注册验证表单'''    
    email = forms.EmailField(required=True)
    password = forms.CharField(required=True,min_length=5)
    # 验证码，字段里面可以自定义错误提示信息
    captcha = CaptchaField()

# users/forms.py

from django import forms
from captcha.fields import CaptchaField


class LoginForm(forms.Form):
    '''登录验证表单'''

    username = forms.CharField(required=True)
    password = forms.CharField(required=True,min_length=5)


class RegisterForm(forms.Form):
    '''注册验证表单'''

    email = forms.EmailField(required=True)
    password = forms.CharField(required=True,min_length=5)
    # 验证码
    captcha = CaptchaField(error_messages={'invalid':'验证码错误'})

forms.py

通过{{ register_form.captcha }}获取验证码

<div class="form-group marb8 captcha1 ">
     <label>验&nbsp;证&nbsp;码</label>
     {{ register_form.captcha }}
</div>

5.5.完善注册的后台逻辑

class RegisterView(View):
    '''用户注册'''
    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', None)
            # 如果用户已存在，则提示错误信息
            if UserProfile.objects.filter(email = user_name):
                return render(request, 'register.html', {'register_form':register_form,'msg': '用户已存在'})

            pass_word = request.POST.get('password', None)
            # 实例化一个user_profile对象
            user_profile = UserProfile()
            user_profile.username = user_name
            user_profile.email = user_name
            user_profile.is_active = False
            # 对保存到数据库的密码加密
            user_profile.password = make_password(pass_word)
            user_profile.save()
            send_register_eamil(user_name,'register')
            return render(request,'login.html')
        else:
            return render(request,'register.html',{'register_form':register_form})

# users/views.py

from django.shortcuts import render
from django.contrib.auth import authenticate,login

from django.contrib.auth.backends import ModelBackend
from .models import UserProfile,EmailVerifyRecord
from django.db.models import Q
from django.views.generic.base import View
from .forms import LoginForm,RegisterForm
from django.contrib.auth.hashers import make_password
from utils.email_send import send_register_eamil

#邮箱和用户名都可以登录
# 基础ModelBackend类，因为它有authenticate方法
class CustomBackend(ModelBackend):
    def authenticate(self, request, username=None, password=None, **kwargs):
        try:
            # 不希望用户存在两个，get只能有一个。两个是get失败的一种原因 Q为使用并集查询
            user = UserProfile.objects.get(Q(username=username)|Q(email=username))

            # django的后台中密码加密：所以不能password==password
            # UserProfile继承的AbstractUser中有def check_password(self, raw_password):
            if user.check_password(password):
                return user
        except Exception as e:
            return None


class LoginView(View):
    '''用户登录'''

    def get(self,request):
        return render(request, 'login.html')

    def post(self,request):
        # 实例化
        login_form = LoginForm(request.POST)
        if login_form.is_valid():
            # 获取用户提交的用户名和密码
            user_name = request.POST.get('username', None)
            pass_word = request.POST.get('password', None)
            # 成功返回user对象,失败None
            user = authenticate(username=user_name, password=pass_word)
            # 如果不是null说明验证成功
            if user is not None:
                if user.is_active:
                    # 只有注册激活才能登录
                    login(request, user)
                    return render(request, 'index.html')
                else:
                    return render(request, 'login.html', {'msg': '用户名或密码错误', 'login_form': login_form})
            # 只有当用户名或密码不存在时，才返回错误信息到前端
            else:
                return render(request, 'login.html', {'msg': '用户名或密码错误','login_form':login_form})

        # form.is_valid（）已经判断不合法了，所以这里不需要再返回错误信息到前端了
        else:
            return render(request,'login.html',{'login_form':login_form})


# 激活用户
class ActiveUserView(View):
    def get(self, request, active_code):
        # 查询邮箱验证记录是否存在
        all_record = EmailVerifyRecord.objects.filter(code = active_code)

        if all_record:
            for record in all_record:
                # 获取到对应的邮箱
                email = record.email
                # 查找到邮箱对应的user
                user = UserProfile.objects.get(email=email)
                user.is_active = True
                user.save()
         # 验证码不对的时候跳转到激活失败页面
        else:
            return render(request,'active_fail.html')
        # 激活成功跳转到登录页面
        return render(request, "login.html", )


class RegisterView(View):
    '''用户注册'''
    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', None)
            # 如果用户已存在，则提示错误信息
            if UserProfile.objects.filter(email = user_name):
                return render(request, 'register.html', {'register_form':register_form,'msg': '用户已存在'})

            pass_word = request.POST.get('password', None)
            # 实例化一个user_profile对象
            user_profile = UserProfile()
            user_profile.username = user_name
            user_profile.email = user_name
            user_profile.is_active = False
            # 对保存到数据库的密码加密
            user_profile.password = make_password(pass_word)
            user_profile.save()
            send_register_eamil(user_name,'register')
            return render(request,'login.html')
        else:
            return render(request,'register.html',{'register_form':register_form})

views.py所以代码

说明：

如果是get请求，直接返回注册页面给用户
如果是post请求，先生成一个表单实例，并获取用户提交的所有信息（request.POST）
is_valid()方法，验证用户的提交信息是不是合法
如果合法，获取用户提交的email和password
实例化一个user_profile对象，把用户添加到数据库
默认添加的用户是激活状态（is_active=1表示True），在这里我们修改默认的状态（改为is_active = False），只有用户去邮箱激活之后才改为True
对密码加密，然后保存，发送邮箱，username是用户注册的邮箱，‘register’表明是注册
注册成功跳转到登录界面

5.6.发送激活邮件

在Python中已经内置了一个smtp邮件发送模块，Django在此基础上进行了简单地封装，让我们在Django环境中可以更方便更灵活的发送邮件。

所有的功能都在django.core.mail中。

首先settings里面设置

# settings.py

EMAIL_HOST = "smtp.qq.com"  # SMTP服务器主机
EMAIL_PORT = 25             # 端口
EMAIL_HOST_USER = "1184405959@qq.com"       # 邮箱地址
EMAIL_HOST_PASSWORD = "dwjybikexxxxxxxx"    # 密码
EMAIL_USE_TLS= True
EMAIL_FROM = "1184405959@qq.com"            # 邮箱地址

说明：

　　 EMAIL_HOST = "smtp.qq.com"

　　 EMAIL_HOST_PASSWORD = "dwjybikexxxxxxxx"

要想用qq邮箱作为服务器发送邮件，必须先开启SMTP，方法如下：

1）登录邮箱，找到“设置”-->>“用户”

2）往下拉找到SMTP服务，点开启，然后点“生成授权码”

3）可以看到授权码，“EMAIL_HOST_PASSWORD”里面填写的就是下面生成的授权码，而不是你的邮箱密码

在apps目录新建package utils,然后新建一个email_send.py文件

# apps/utils/email_send.py

from random import Random
from django.core.mail import send_mail

from users.models import EmailVerifyRecord
from MxOnline.settings import EMAIL_FROM

# 生成随机字符串
def random_str(random_length=8):
    str = ''
    # 生成字符串的可选字符串
    chars = 'AaBbCcDdEeFfGgHhIiJjKkLlMmNnOoPpQqRrSsTtUuVvWwXxYyZz0123456789'
    length = len(chars) - 1
    random = Random()
    for i in range(random_length):
        str += chars[random.randint(0, length)]
    return str

# 发送注册邮件
def send_register_eamil(email, send_type="register"):
    # 发送之前先保存到数据库，到时候查询链接是否存在
    # 实例化一个EmailVerifyRecord对象
    email_record = EmailVerifyRecord()
    # 生成随机的code放入链接
    code = random_str(16)
    email_record.code = code
    email_record.email = email
    email_record.send_type = send_type

    email_record.save()

    # 定义邮件内容:
    email_title = ""
    email_body = ""

    if send_type == "register":
        email_title = "NBA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)

        # 使用Django内置函数完成邮件发送。四个参数：主题，邮件内容，发件人邮箱地址，收件人（是一个字符串列表）
        send_status = send_mail(email_title, email_body, EMAIL_FROM, [email])
        # 如果发送成功
        if send_status:
            pass

官方文档：

def send_mail(subject, message, from_email, recipient_list,
              fail_silently=False, auth_user=None, auth_password=None,
              connection=None, html_message=None):

前面四个参数必须要，后面的参数可以为空

发送电子邮件的最简单方法是使用 django.core.mail.send_mail()。

的subject，message，from_email和recipient_list参数是必需的。

subject：一个字符串。
message：一个字符串。
from_email：一个字符串。
recipient_list：字符串列表，每个字符串都是电子邮件地址。每个成员都recipient_list将在电子邮件的“收件人：”字段中看到其他收件人。
fail_silently：一个布尔值。如果是的话False，send_mail会提出一个smtplib.SMTPException。有关smtplib可能的例外列表，请参阅文档，所有这些例外都是。的子类 SMTPException。
auth_user：用于向SMTP服务器进行身份验证的可选用户名。如果没有提供，Django将使用该EMAIL_HOST_USER设置的值。
auth_password：用于验证SMTP服务器的可选密码。如果没有提供，Django将使用该EMAIL_HOST_PASSWORD设置的值。
connection：用于发送邮件的可选电子邮件后端。如果未指定，将使用默认后端的实例。有关更多详细信息，请参阅电子邮件后端的文档。
html_message：如果html_message被提供，所得到的电子邮件将是一个多部分/替代电子邮件message作为文本/无格式内容类型和html_message作为 text / html的内容类型。

返回值将是成功传递消息的数量（可以是0或1因为它只能发送一条消息）。

5.7.激活用户

根据邮箱找到对应的用户，然后设置is_active = True来实现

# 激活用户
class ActiveUserView(View):
    def get(self, request, active_code):
        # 查询邮箱验证记录是否存在
        all_record = EmailVerifyRecord.objects.filter(code = active_code)

        if all_record:
            for record in all_record:
                # 获取到对应的邮箱
                email = record.email
                # 查找到邮箱对应的user
                user = UserProfile.objects.get(email=email)
                user.is_active = True
                user.save()
         # 验证码不对的时候跳转到激活失败页面
        else:
            return render(request,'active_fail.html')
        # 激活成功跳转到登录页面
        return render(request, "login.html", )

在templates目录下创建 active_fail.html,代码如下：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <p style="color: red;">链接失效</p>
</body>
</html>

激活邮箱的邮件如下：

修改login视图

添加一个判断，用户注册的后，等激活才能登陆

# users/views.py

from django.shortcuts import render
from django.contrib.auth import authenticate,login

from django.contrib.auth.backends import ModelBackend
from .models import UserProfile,EmailVerifyRecord
from django.db.models import Q
from django.views.generic.base import View
from .forms import LoginForm,RegisterForm
from django.contrib.auth.hashers import make_password
from utils.email_send import send_register_eamil

#邮箱和用户名都可以登录
# 基础ModelBackend类，因为它有authenticate方法
class CustomBackend(ModelBackend):
    def authenticate(self, request, username=None, password=None, **kwargs):
        try:
            # 不希望用户存在两个，get只能有一个。两个是get失败的一种原因 Q为使用并集查询
            user = UserProfile.objects.get(Q(username=username)|Q(email=username))

            # django的后台中密码加密：所以不能password==password
            # UserProfile继承的AbstractUser中有def check_password(self, raw_password):
            if user.check_password(password):
                return user
        except Exception as e:
            return None


class LoginView(View):
    '''用户登录'''

    def get(self,request):
        return render(request, 'login.html')

    def post(self,request):
        # 实例化
        login_form = LoginForm(request.POST)
        if login_form.is_valid():
            # 获取用户提交的用户名和密码
            user_name = request.POST.get('username', None)
            pass_word = request.POST.get('password', None)
            # 成功返回user对象,失败None
            user = authenticate(username=user_name, password=pass_word)
            # 如果不是null说明验证成功
            if user is not None:
                if user.is_active:
                    # 只有注册激活才能登录
                    login(request, user)
                    return render(request, 'index.html')
                else:
                    return render(request, 'login.html', {'msg': '用户名或密码错误', 'login_form': login_form})
            # 只有当用户名或密码不存在时，才返回错误信息到前端
            else:
                return render(request, 'login.html', {'msg': '用户名或密码错误','login_form':login_form})

        # form.is_valid（）已经判断不合法了，所以这里不需要再返回错误信息到前端了
        else:
            return render(request,'login.html',{'login_form':login_form})


# 激活用户的view

                user.is_active = True
                user.save()
                # 激活成功跳转到登录页面
                return render(request, "login.html", )
        # 自己瞎输的验证码
        else:
            return render(request, "register.html", {"msg": "您的激活链接无效"})


class RegisterView(View):
    '''用户注册'''
    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', None)
            pass_word = request.POST.get('password', None)

            # 实例化一个user_profile对象
            user_profile = UserProfile()
            user_profile.username = user_name
            user_profile.email = user_name
            user_profile.is_active = False

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

views.py

修改register.html

 <form id="email_register_form" method="post" action="{% url 'register' %}" autocomplete="off">
                        <input type='hidden' name='csrfmiddlewaretoken' value='gTZljXgnpvxn0fKZ1XkWrM1PrCGSjiCZ' />

                    <input type='hidden' name='csrfmiddlewaretoken' value='5I2SlleZJOMUX9QbwYLUIAOshdrdpRcy' />
                    {% csrf_token %}
                    </form>

修改的地方说明：

value="{{ register_form.email.value }}

value="{{ register_form.password.value }}    注册的用户不用再手动输入一遍邮箱和密码了

{% if login_form.errors.email %}errorput{% endif %}

{% if login_form.errors.password %}errorput{% endif %}

{% if login_form.errors.captchal %}errorput{% endif %}    提示错误信息并显示红框框

{{ register_form.captcha }}    显示验证码

添加邮件激活的url

# MxOnline/urls.py

import xadmin

from django.urls import path,include,re_path

from django.views.generic import TemplateView
from users.views import LoginView,RegisterView,ActiveUserView


urlpatterns = [
    path('xadmin/', xadmin.site.urls),
    path('', TemplateView.as_view(template_name='index.html'),name='index'),
    path('login/',LoginView.as_view(),name = 'login'),
    path('register/',RegisterView.as_view(),name = 'register'),
    path('captcha/',include('captcha.urls')),
    re_path('active/(?P<active_code>.*)/',ActiveUserView.as_view(),name='user_active'),
]

六、找回密码

主要需要实现的功能：

用户点“忘记密码”，跳到找回密码页面
在forgetpwd页面，输入邮箱和验证码成功后，发送邮件提醒
通过点击邮件链接，可以重置密码
两次密码输的正确无误后，密码更新成功，跳到登录界面

6.1.路由设计

from users.views import ForgetPwdView

urlpatterns = [
    path('forget/',ForgetPwdView.as_view(),name='forget_pwd'),
]

6.2.初步视图函数

首先也需要个表单

forms.py

class ForgetPwdForm(forms.Form):
    '''忘记密码'''
    email = forms.EmailField(required=True)
    captcha = CaptchaField(error_messages={'invalid': '验证码错误'})

视图函数

class ForgetPwdView(View):
    '''找回密码'''
    def get(self,request):
        forget_form = ForgetPwdForm()
        return render(request,'forgetpwd.html',{'forget_form':forget_form})

get方式，直接返回忘记密码的表单

6.3.模板修改

修改login.html中的url

<a class="fr" href="{% url 'forget_pwd' %}">忘记密码？</a>

把forgetpwd.html拷贝到templates文件下

修改静态文件路径

显示验证码

 <div class="form-group captcha1 marb38">
     <label>验&nbsp;证&nbsp;码</label>
     {{ forget_pwd.captcha }}
 </div>

6.4.添加发送找回密码邮件

修改utils/email_send.py

发送类型为“forget”

    if send_type == "forget":
        email_title = "NBA找回密码链接"
        email_body = "请点击下面的链接找回你的密码: http://127.0.0.1:8000/reset/{0}".format(code)

        # 使用Django内置函数完成邮件发送。四个参数：主题，邮件内容，从哪里发，接受者list
        send_status = send_mail(email_title, email_body, EMAIL_FROM, [email])
        # 如果发送成功
        if send_status:
            pass

# apps/utils/email_send.py

from random import Random
from django.core.mail import send_mail

from users.models import EmailVerifyRecord
from MxOnline.settings import EMAIL_FROM

# 生成随机字符串
def random_str(random_length=8):
    str = ''
    # 生成字符串的可选字符串
    chars = 'AaBbCcDdEeFfGgHhIiJjKkLlMmNnOoPpQqRrSsTtUuVvWwXxYyZz0123456789'
    length = len(chars) - 1
    random = Random()
    for i in range(random_length):
        str += chars[random.randint(0, length)]
    return str

# 发送注册邮件
def send_register_eamil(email, send_type="register"):
    # 发送之前先保存到数据库，到时候查询链接是否存在
    # 实例化一个EmailVerifyRecord对象
    email_record = EmailVerifyRecord()
    # 生成随机的code放入链接
    code = random_str(16)
    email_record.code = code
    email_record.email = email
    email_record.send_type = send_type

    email_record.save()

    # 定义邮件内容:
    email_title = ""
    email_body = ""

    if send_type == "register":
        email_title = "NBA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)

        # 使用Django内置函数完成邮件发送。四个参数：主题，邮件内容，从哪里发，接受者list
        send_status = send_mail(email_title, email_body, EMAIL_FROM, [email])
        # 如果发送成功
        if send_status:
            pass

    if send_type == "forget":
        email_title = "NBA找回密码链接"
        email_body = "请点击下面的链接找回你的密码: http://127.0.0.1:8000/reset/{0}".format(code)

        # 使用Django内置函数完成邮件发送。四个参数：主题，邮件内容，从哪里发，接受者list
        send_status = send_mail(email_title, email_body, EMAIL_FROM, [email])
        # 如果发送成功
        if send_status:
            pass

email_send.py

6.5.完善找回密码的views

class ForgetPwdView(View):
    '''找回密码'''
    def get(self,request):
        forget_form = ForgetPwdForm()
        return render(request,'forgetpwd.html',{'forget_form':forget_form})

    def post(self,request):
        forget_form = ForgetPwdForm(request.POST)
        if forget_form.is_valid():
            email = request.POST.get('email',None)
            send_register_eamil(email,'forget')
            return render(request, 'send_success.html')
        else:
            return render(request,'forgetpwd.html',{'forget_form':forget_form})

用户提交邮箱后，提醒成功发送邮件

新建templates/send_success.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <p>邮件已发送，请注意查收</p>
</body>
</html>

修改forgetpwd.html

 <form id="jsFindPwdForm" method="post" action="{% url 'forget_pwd' %}" autocomplete="off">
                    <input type='hidden' name='csrfmiddlewaretoken' value='mymQDzHWl2REXIfPMg2mJaLqDfaS1sD5'/>
                    <div class="form-group marb20 {% if forget_from.errors.email %}errorput{% endif %}">
                        <label>帐&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;号</label>
                        <input type="text" id="account" name="email" value="{{ forget_from.email.value }}"
                               placeholder="邮箱"/>
                    </div>
                    <div class="form-group captcha1 marb38 {% if forget_from.errors.captchal %}errorput{% endif %}">
                        <label>验&nbsp;证&nbsp;码</label>
                        {{ forget_form.captcha }}
                    </div>
                    <div class="error btns" id="jsForgetTips">
                        {% for key,error in forget_from.errors.items %}
                            {{ error }}
                        {% endfor %}
                        {{ msg }}
                    </div>
                    <input type="hidden" name="sms_type" value="1">
                    <input class="btn btn-green" id="jsFindPwdBtn" type="submit" value="提交"/>
                    <p class="form-p" style="bottom:40px;">您还可以<a href="login.html"> [直接登录]</a></p>
                    <input type='hidden' name='csrfmiddlewaretoken' value='5I2SlleZJOMUX9QbwYLUIAOshdrdpRcy'/>
                    {% csrf_token %}
                </form>

测试一下，输入邮箱和验证码看能不能收到邮件

6.6.重置密码

（1）重置密码激活邮箱的url

 re_path('reset/(?P<active_code>.*)/', ResetView.as_view(), name='reset_pwd'),

（2）写重置密码（get方式）后台逻辑

class ResetView(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
                return render(request, "password_reset.html", {"email":email})
        else:
            return render(request, "active_fail.html")
        return render(request, "login.html")

（3）创建修改密码的form表单

class ModifyPwdForm(forms.Form):
    '''重置密码'''
    password1 = forms.CharField(required=True, min_length=5)
    password2 = forms.CharField(required=True, min_length=5)

（4）修改密码的url

上面那个是激活邮箱的url，有active_code参数，只能写get方式的逻辑。

这里必须单独新建一个修改密码的url,因为如果以post方式提交的话，post提交的地方跟get方式（url中需要active_code参数）的地址不一样，action="{% url 'modify_pwd' %}

path('modify_pwd/', ModifyPwdView.as_view(), name='modify_pwd'),

（5）修改密码的后台逻辑

class ModifyPwdView(View):
    def post(self, request):
        modify_form = ModifyPwdForm(request.POST)
        if modify_form.is_valid():
            pwd1 = request.POST.get("password1", "")
            pwd2 = request.POST.get("password2", "")
            email = request.POST.get("email", "")
            if pwd1 != pwd2:
                return render(request, "password_reset.html", {"email":email, "msg":"密码不一致！"})
            user = UserProfile.objects.get(email=email)
            user.password = make_password(pwd2)
            user.save()

            return render(request, "login.html")
        else:
            email = request.POST.get("email", "")
            return render(request, "password_reset.html", {"email":email, "modify_form":modify_form })

（6）修改password_reset.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="renderer" content="webkit">
    <meta http-equiv="X-UA-Compatible" content="IE=Edge,chrome=1">

                    <input type="password" name="password1" id="pwd" placeholder="6-20位非中文字符">

                </li>
                <input type="hidden" name="email" value="{{ email }}">
                <li class="{% if modify_form.errors.password2 %}errorput{% endif %}">

                <div class="error btns" id="jsPasswdResetTips">
                    {% for key,error in modify_form.errors.items %}{{ key }}:{{ error }}{% endfor %}{{ msg }}</div>
                <li class="button">

            {% csrf_token %}
        </form>
    </div>
    <div class="resetpassword" id="reset_password_tips" style="display:none;">
        <h1>修改密码成功,请重新登录</h1>
        <img class="fl" src="/static/images/check2.png">
