Python通过Django实现用户注册和邮箱验证功能代码

 def get(self, request):
  register_form = RegisterForm()
  return render(request, "register.html", {'register_form':register_form})

 def post(self, request):
  # 实例化form，验证每个字段是否合法
  register_form = RegisterForm(request.POST)
  pre_check = register_form.is_valid()
  if pre_check:
   # 取出email和password
   user_name = request.POST.get("email", "")
   pass_word = request.POST.get("password", "")
   # 实例化用户，然后赋值
   user_profile = UserProfile()
   user_profile.username = user_name
   user_profile.email = user_name
   # 新建用户为非活跃用户，可通过验证变为活跃用户
   user_profile.is_active = False
   # 将明文转换为密文赋给password
   user_profile.password = make_password(pass_word)
   user_profile.save() # 保存到数据库
   # 此处加入了邮箱验证的手段
   send_register_email(user_name, "register")
   return render(request, "login.html")
  else:
   # form表单验证失败，将错误信息传给前端
   return render(request, "register.html", {"register_form": register_form})
