django开发忘记密码通过邮箱找回功能

2018-04-16 16:27 出处:清屏网 人气: 评论(0

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' %}">忘记密码</a>),就可以完成通过邮箱找回密码的功能啦!
