我想在Django中编写自定义用户，但是重置密码时出现了问题。我在urls.py中使用以下URL：
url(r'^reset_password_confirm/(?P<uidb64>[0-9A-Za-z_\-\']+)-(?P<token>[0-9A-Za-z\-\']+)/$', PasswordResetConfirmView.as_view() , name='reset_password_confirm'),
url(r'^reset_password', ResetPasswordRequestView.as_view())
这是我对重置密码并确认的观点：
class ResetPasswordRequestView(FormView):
# User = get_user_model()
template_name = "test_template.html" #code for template is given below the view's code
success_url = 'reset_password'
form_class = PasswordResetRequestForm
@staticmethod
def validate_email_address(email):
try:
validate_email(email)
return True
except ValidationError:
return False
def post(self, request, *args, **kwargs):
form = self.form_class(request.POST)
if form.is_valid():
data= form.cleaned_data["email_or_username"]
if self.validate_email_address(data) is True: #uses the method written above

该邮件包含一个无效链接，比如：HTTP://127.0.0.1:8000/reset_password_confirm/b'MjM'-4y1-68809e63d52242805bd7/
当我点击它时，出现了以下信息，显示这是一个无效的链接：The password reset link was invalid, possibly because it has already been used. Please request a new password reset。
我已经搜索了很多但没有找到解决方法。请问有人能帮助我吗？非常感谢。
