传递 PayPal Buttons 项目对象

Question

我有点头疼，我想开一家商店，以三种尺寸出售一种东西，然后将这些物品传递给 paypal 付款：

            let itemsArray = [];
            let pplrg = parseInt(document.getElementById('lrg').value);
            let ppsml = parseInt(document.getElementById('sml').value);
            let ppcld = parseInt(document.getElementById('cld').value);
            let ppvalue = 0;
            if(pplrg > 0) {
                itemsArray.push({"name": "Adult Large", "description": "Adult Large size", "unit_amount": { "currency_code": "AUD", "value": "25.95"}, "quantity": pplrg.toString()});
                ppvalue+= pplrg * 25.95
            }
            if(ppsml > 0) {
                itemsArray.push({"name": "Adult Small", "description": "Adult Small size", "unit_amount": { "currency_code": "AUD", "value": "25.95"}, "quantity": ppsml.toString()});
                ppvalue+= ppsml * 25.95
            }
            if(ppcld > 0) {
                itemsArray.push({"name": "Child", "description": "Child size", "unit_amount": { "currency_code": "AUD", "value": "24.95"}, "quantity": ppcld.toString()});
                ppvalue+= ppsml * 24.95
            }
            console.log(JSON.stringify(itemsArray));
            
            paypal.Buttons({
                createOrder: function(data, actions) {
                  return actions.order.create({
                     "purchase_units": [{
                        "amount": {
                          "currency_code": "AUD",
                          "value": ppvalue.toFixed(2),
                          "breakdown": {
                            "item_total": {
                              "currency_code": "AUD",
                              "value": ppvalue.toFixed(2)
                            }
                          }
                        },
                        "items": JSON.stringify(itemsArray)
                      }]
                  });
                },
                
                onApprove: function(data, actions) {
                  return actions.order.capture().then(function(orderData) {
                    // Successful capture! For dev/demo purposes:
                        console.log('Capture result', orderData, JSON.stringify(orderData, null, 2));
                        let transaction = orderData.purchase_units[0].payments.captures[0];
                        let email = transaction.payer[0].email_address;
                        console.log(email);
                        alert('Transaction '+ transaction.status + ': ' + transaction.id + '\n\nSee console for all available details');
                        
                    // When ready to go live, remove the alert and show a success message within this page. For example:
                    var element = document.getElementById('paypal-button-container');
                    element.innerHTML = '';
                    element.innerHTML = '<h3>Thank you for your payment!</h3>';
                    element.innerHTML+= '<p>Paypal should be sending you an receipt with details of your order to '+email+'.</p>';
                  });
                }
            }).render('#paypal-button-container');

这不起作用，但是，如您所见，我 console.log JSON.stringify(itemsArray) 的内容，如果我将 paypal.Buttons 中的 JSON.stringify(itemsArray) 替换为 paypal.Buttons 的内容控制台，它工作正常。即：

            let itemsArray = [];
            let pplrg = parseInt(document.getElementById('lrg').value);
            let ppsml = parseInt(document.getElementById('sml').value);
            let ppcld = parseInt(document.getElementById('cld').value);
            let ppvalue = 0;
            if(pplrg > 0) {
                itemsArray.push({"name": "Adult Large", "description": "Adult Large size", "unit_amount": { "currency_code": "AUD", "value": "25.95"}, "quantity": pplrg.toString()});
                ppvalue+= pplrg * 25.95
            }
            if(ppsml > 0) {
                itemsArray.push({"name": "Adult Small", "description": "Adult Small size", "unit_amount": { "currency_code": "AUD", "value": "25.95"}, "quantity": ppsml.toString()});
                ppvalue+= ppsml * 25.95
            }
            if(ppcld > 0) {
                itemsArray.push({"name": "Child", "description": "Child size", "unit_amount": { "currency_code": "AUD", "value": "24.95"}, "quantity": ppcld.toString()});
                ppvalue+= ppsml * 24.95
            }
            console.log(JSON.stringify(itemsArray));
            
            paypal.Buttons({
                createOrder: function(data, actions) {
                  return actions.order.create({
                     "purchase_units": [{
                        "amount": {
                          "currency_code": "AUD",
                          "value": ppvalue.toFixed(2),
                          "breakdown": {
                            "item_total": {
                              "currency_code": "AUD",
                              "value": ppvalue.toFixed(2)
                            }
                          }
                        },
                        "items": [{"name":"'Adult Large","description":"Adult Large size","unit_amount":{"currency_code":"AUD","value":"25.95"},"quantity":"1"},{"name":"Adult Small","description":"Adult Small size","unit_amount":{"currency_code":"AUD","value":"25.95"},"quantity":"1"}]
                      }]
                  });
                },
                
                onApprove: function(data, actions) {
                  return actions.order.capture().then(function(orderData) {
                    // Successful capture! For dev/demo purposes:
                        console.log('Capture result', orderData, JSON.stringify(orderData, null, 2));
                        let transaction = orderData.purchase_units[0].payments.captures[0];
                        let email = transaction.payer[0].email_address;
                        console.log(email);
                        alert('Transaction '+ transaction.status + ': ' + transaction.id + '\n\nSee console for all available details');
                        
                    // When ready to go live, remove the alert and show a success message within this page. For example:
                    var element = document.getElementById('paypal-button-container');
                    element.innerHTML = '';
                    element.innerHTML = '<h3>Thank you for your payment!</h3>';
                    element.innerHTML+= '<p>Paypal should be sending you an receipt with details of your order to '+email+'.</p>';
                  });
                }
            }).render('#paypal-button-container');

这才是真正让我感到困惑的地方，显然我已经正确构建了我的 itemsArray 并且 JSON.stringify(itemsArray) 以 PayPal 期望的格式呈现文本，但是，它不起作用，有人吗有更多经验的人可以告诉我我做错了什么吗？

我已经对这个问题进行了相当多的搜索，我知道有一些关于这个的问题，但它们似乎都与我遇到的问题有点不同。

Answer 1

简单

"items": itemsArray

没有理由对将要分配给对象中的字符串值的内容进行字符串化，该对象稍后将再次进行字符串化以进行传输。
