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 formsfrom 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,redirectfrom django.http import HttpResponsefrom users.form import ForgetForm,ResetFormfrom .models import UserProfilefrom django.contrib.auth.hashers import make_passwordfrom apps.utils.email_send import send_register_emailfrom .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！
