如何在PayPal中傳遞總額至（金額：{total：'0.01'，currency：'USD'}）

Question

我已經在我的asp.net網頁中實現了paypal checkout express按鈕。我怎樣才能將orderTotal傳遞給金額：{total：'0.01'，currency：'USD'}。默認情況下它是'0.01'我想要顯示實際的orderTotal。 這是我的代碼 paypal.Button.render（{

            env: 'sandbox', // sandbox | production 

               // PayPal Client IDs - replace with your own 
               // Create a PayPal app: https://developer.paypal.com/developer/applications/create 
               client: { 
                sandbox: 'AZDxjDScFpQtjWTOUtWKbyN_bDt4OgqaF4eYXlewfBP4-8aqX3PiV8e1GWU6liB2CUXlkA59kJXE7M6R', 
                //production: 'AVSYgEO5SUewyQ_We4dW5uCXyEZHgcFDfKK15gCqsd7o0edVH5UOhtHK7n2uqkFQOYtjJt0vvemfgNwg' 
               }, 

               // Show the buyer a 'Pay Now' button in the checkout flow 
               commit: true, 

               // payment() is called when the button is clicked 
               payment: function (data, actions) { 

                // Make a call to the REST api to create the payment 
                return actions.payment.create({ 
                 payment: { 
                  transactions: [ 
                  { 
                   amount: { total: '0.01', currency: 'USD' } 
                  } 
                  ] 
                 } 
                }); 
               }, 
               commit: true, 
               // onAuthorize() is called when the buyer approves the payment 
               onAuthorize: function (data, actions) { 
                // Make a call to the REST api to execute the payment 
                return actions.payment.execute().then(function() { 
                 //window.alert('Payment Complete!'); 
                 onPaypalAuthorize(); 
                }); 
               } 

              }, '#paypal-button-container');

根據您是否使用窗體或MVC。

Web窗體可以使用inline指令 <% =MyTotal %>，你想總。

隨着MVC @ model.MyTotal會在哪裏工作MyTotal將是你想總要傳遞給貝寶。

˚F或者例如，WebForms的

amount: { total: <% =MyTotal %>, currency: 'USD' } 

MVC

amount: { total: @Model.MyTotal, currency: 'USD' } 

一對夫婦的需要指出的事。總數需要是一個字符串，並且需要舍入到兩位小數點。如果你不這樣做，它會反彈和錯誤。
