c# - Asp MVC Paypal 交易

Question

我正在尝试制作一个 paypal 处理程序。你在输入中输入金额，然后按下捐赠按钮，你将被转发到 Paypal 页面，你可以登录然后按下继续按钮......按下继续按钮后的问题将我转发回 https://www.example.org/Account/PayPalHandler/页，仅此而已。我的代码缺少什么来完成 Paypal 交易？

[HttpPost]
        public ActionResult DoPaymentPaypall(UserModel User_)
        {
            ResultModel<ManageAccountListModel> res_ = new ResultModel<ManageAccountListModel>();
            res_.DataSelect = new ManageAccountListModel();

            if (SessionManagement.LoginnedUser != null)
            {
                var config = ConfigManager.Instance.GetProperties();
                var accessToken = new OAuthTokenCredential(config).GetAccessToken();
                var apiContext = new APIContext(accessToken);
                string moneyCount_ = User_.moneycount.ToString();
                var payment = Payment.Create(apiContext, new Payment
                {
                    intent = "sale",
                    payer = new Payer
                    {
                        payment_method = "paypal"
                    },
                    transactions = new List<Transaction>
                                    {

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

链接显示完整流程

• Create payment(这是您上面的代码映射到的内容)- 您将在此步骤中获得一个payment id
• 使用您收到的 id 将用户重定向到 Paypal approval_url 以获得批准(详细信息在上面的 Create 中)
• Paypal 将用户发送回您的网站，并提供有关如何执行 付款的信息(如果用户同意)
• 执行付款(这是在您的站点/应用程序中完成的)
