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！
