odoo 支付接入 - 参考paypal模块

paypal 模块整理

确认订单上 生成 paypal 支付表单

表单包含 订单号，地址，邮箱，价格 等其他订单信息 以及

• return
• paypal nofify
• paypal cancel url

下面我们看看，paypal 这三张地址如何处理
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/">

@http.route('/payment/paypal/dpn', type='http', auth="none", methods=['POST'])
    def paypal_dpn(self, **post):
        """ Paypal DPN """
        _logger.info('Beginning Paypal DPN form_feedback with post data %s', pprint.pformat(post))  # debug
        return_url = self._get_return_url(**post)
        self.paypal_validate_data(**post)
        return werkzeug.utils.redirect(return_url)

notify (IPN)

<input type="hidden" name="notify_url" value="http://192.168.12.207:6182/payment/paypal/ipn/">

@http.route('/payment/paypal/ipn/', type='http', auth='none', methods=['POST'])
    def paypal_ipn(self, **post):
        """ Paypal IPN. """
        _logger.info('Beginning Paypal IPN form_feedback with post data %s', pprint.pformat(post))  # debug
        self.paypal_validate_data(**post)
        return ''

处理post 表单数据
返回支付成功验证信息

cancel

<input type="hidden" name="cancel_return" value="http://192.168.12.207:6182/payment/paypal/cancel/">
返回取消信息
