一、流程分析：

1.点击忘记密码====》forget.html页面，输入邮箱和验证码，发送验证链接网址的邮件====》发送成功，跳到send_success.html提示

2.到邮箱里找到验证链接网址，访问重设密码网址reset.html===》重设密码提交数据，成功则返回首页，失败则返回错误信息

二、

1.users/forms.py文件中

from django import forms
from captcha.fields import CaptchaField


.......

#forget.html中，用于验证邮箱格式和验证码
class ForgetForm(forms.Form):
  email=forms.EmailField(required=True)
  captcha=CaptchaField(error_messages={'invalid':'验证码错误'})

#reset.html中，用于验证新设的密码长度是否达标
class ResetForm(forms.Form):
  newpwd1=forms.CharField(required=True,min_length=6,error_messages={'required': '密码不能为空.', 'min_length': "至少6位"})
  newpwd2 = forms.CharField(required=True, min_length=6, error_messages={'required': '密码不能为空.', 'min_length': "至少6位"})

2.users/views.py中相关代码：

......
from django.shortcuts import render,redirect
from django.http import HttpResponse
from users.form import ForgetForm,ResetForm
from .models import UserProfile
from django.contrib.auth.hashers import make_password
from apps.utils.email_send import send_register_email
from .models import EmailVerifyRecord

......

class ForgetPwdView(View):
  '''忘记密码'''
  def get(self,request):
    forget_form=ForgetForm()
    return render(request,'forget.html',{'forget_form':forget_form})
  def post(self,request):
    forget_form = ForgetForm(request.POST)
    if forget_form.is_valid():
      email=request.POST.get('email','')
      send_register_email(email,'forget')
      return render(request,'send_success.html')
    else:
      return render(request,'forget.html',{'forget_form':forget_form})


class ResetView(View):
  '''重置密码'''
  def get(self,request,active_code):
    record=EmailVerifyRecord.objects.filter(code=active_code)
    print(record)
    if record:
      for i in record:
        email=i.email
        is_register=UserProfile.objects.filter(email=email)
        if is_register:
          return render(request,'pwd_reset.html',{'email':email})
    return redirect('index')


#因为<form>表单中的路径要是确定的，所以post函数另外定义一个类来完成
class ModifyView(View):
  """重置密码post部分"""
  def post(self,request):
    reset_form=ResetForm(request.POST)
    if reset_form.is_valid():
      pwd1=request.POST.get('newpwd1','')
      pwd2=request.POST.get('newpwd2','')
      email=request.POST.get('email','')
      if pwd1!=pwd2:
        return render(request,'pwd_reset.html',{'msg':'密码不一致！'})
      else:
        user=UserProfile.objects.get(email=email)
        user.password=make_password(pwd2)
        user.save()
        return redirect('index')
    else:
      email=request.POST.get('email','')
      return render(request,'pwd_reset.html',{'msg':reset_form.errors})

3.新建forget.html， success_send.html， pwd_reset.html

#forget.html

<!DOCTYPE html>
{% load staticfiles %}
<html lang="en">

<head>
  <meta charset="UTF-8">
  <title>忘记密码</title>

<style>
.out{
  width: 500px;
  height: 900px;
  margin: 0 auto;
  margin-top: 100px;
}
</style>
</head>
<body>


  <div class="out">
    <h1>真粗心，忘了密码吧？快通过邮箱找回密码吧！</h1>
    <form method="post" action="{% url 'forget_pwd' %}">
      <P><span>邮箱：</span><input type="text" name="email"></P>
      <P><span>验证码：</span>{{ forget_form.captcha }}</P>
      {% csrf_token %}
      <p><input type="submit" value="确认发送验证邮件"></p>
    </form>
    <h1>{{ forget_form.errors }}</h1>
  </div>


</body>
</html>

#success_send.html

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Title</title>
</head>
<body>
<h1>发送邮件成功，快去邮箱查看吧！（收件箱没有，垃圾箱一定有……）</h1>
</body>
</html>

#pwd_reset.html

<!DOCTYPE html>
{% load staticfiles %}
<html lang="en">

<head>
  <meta charset="UTF-8">
  <title>重置密码</title>

<style>
.out{
  width: 500px;
  height: 900px;
  margin: 0 auto;
  margin-top: 100px;
}
</style>
</head>
<body>


  <div class="out">
    <h1>可以重新设置一个好记的新密码啦！</h1>
    <form method="post" action="{% url 'modify' %}">
      <P><span>新密码：</span><input type="password" name="newpwd1" placeholder="至少6位"></P>
      <P><span>确认新密码：</span><input type="password" name="newpwd2" placeholder="至少6位"></P>
      {% csrf_token %}
      <input type="hidden" name="email" value="{{ email }}">
      <p><input type="submit" value="确认"></p>
    </form>
    <h1>{{ msg }}</h1>
  </div>

</body>
</html>

4.配置相关的urls.py：

from users.views import ForgetPwdView,ResetView,ModifyView

......

urlpatterns = [
  .....

  #忘记密码
  path('forget/',ForgetPwdView.as_view(),name='forget_pwd'),
  #重置密码
  path('reset/<str:active_code>',ResetView.as_view(),name='reset'),
  path('modify/',ModifyView.as_view(),name='modify'),


  ......
]

运行项目，点击忘记密码链接（<a href="{% url 'forget_pwd' %}" rel="external nofollow" >忘记密码</a>），就可以完成通过邮箱找回密码的功能啦！

5.send_register_email()方法及其配置详见上一篇文章
