Asp MVC 贝宝交易

Question

我正在尝试制作一个贝宝处理程序。您在输入中输入金额，然后按捐赠按钮，您将被转发到贝宝页面，您可以登录，然后按继续按钮...按继续按钮后的问题将我转发回@ 987654321@ 页，仅此而已。我的代码中缺少什么来完成贝宝交易？

[HttpPost]
        public ActionResult DoPaymentPaypall(UserModel User_)

            ResultModel<ManageAccountListModel> res_ = new ResultModel<ManageAccountListModel>();
            res_.DataSelect = new ManageAccountListModel();

Answer 1

您上面的代码似乎只显示了流程的初始/开始...所以假设您的意思是在用户批准您的之后请求 使用 Paypal 付款（不要将此混淆为“付款” - 此步骤仅表示用户同意使用 Paypal 付款）您需要Execute the payment。

• Create 付款（这是您上面的代码所映射的内容）- 在此步骤中您将获得 payment id
• 使用您收到的id 将用户重定向到 Paypal approval_url 以获得批准（上面Create 中的详细信息）
• Paypal 将用户发送回您的网站，并提供有关如何Execute 付款的信息（如果用户批准）
• Execute 付款（在您的网站/应用中完成）
