在模块 payment_paypal 中的 controllers/main.py
return<input type="hidden" name="return" value="http://192.168.12.207:6182/payment/paypal/dpn/">

2.     def paypal_dpn(self, **post):
   
3.         """ Paypal DPN """
   
4.         _logger.info('Beginning Paypal DPN form_feedback with post data %s', pprint.pformat(post))  # debug
   
5.         return_url = self._get_return_url(**post)
   
6.         self.paypal_validate_data(**post)
   
7.         return werkzeug.utils.redirect(return_url)
