django 开发忘记密码通过邮箱找回功能示例

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})
