一、流程分析：

1.點擊忘記密碼====》forget.html頁面，輸入郵箱和驗證碼，發送驗證鏈接網址的郵件====》發送成功，跳到send_success.html提示

2.到郵箱里找到驗證鏈接網址，訪問重設密碼網址reset.html===》重設密碼提交數據，成功則返回首頁，失敗則返回錯誤信息

二、

1.users/forms.py文件中

from django import formsfrom captcha.fields import CaptchaField.......#forget.html中，用于驗證郵箱格式和驗證碼class ForgetForm(forms.Form):  email=forms.EmailField(required=True)  captcha=CaptchaField(error_messages={'invalid':'驗證碼錯誤'})#reset.html中，用于驗證新設的密碼長度是否達標class ResetForm(forms.Form):  newpwd1=forms.CharField(required=True,min_length=6,error_messages={'required': '密碼不能為空.', 'min_length': "至少6位"})  newpwd2 = forms.CharField(required=True, min_length=6, error_messages={'required': '密碼不能為空.', 'min_length': "至少6位"})

2.users/views.py中相關代碼：

......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):  '''忘記密碼'''  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):  '''重置密碼'''  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')#因為<form>表單中的路徑要是確定的，所以post函數另外定義一個類來完成class ModifyView(View):  """重置密碼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':'密碼不一致！'})      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})
