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

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

{% load staticfiles %}

忘记密码

.out{

width: 500px;

height: 900px;

margin: 0 auto;

margin-top: 100px;

}

#success_send.html

Title

发送邮件成功，快去邮箱查看吧！(收件箱没有，垃圾箱一定有……)

#pwd_reset.html

{% load staticfiles %}

重置密码

.out{

width: 500px;

height: 900px;

margin: 0 auto;

margin-top: 100px;

}

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/',ResetView.as_view(),name='reset'),

path('modify/',ModifyView.as_view(),name='modify'),

......

]

运行项目，点击 忘记密码 链接(忘记密码)，就可以完成通过邮箱找回密码的功能啦！
