django 开发忘记密码通过邮箱找回功能
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！
