PayPal快速结账:无法使用沙盒测试帐户处理付款

我尝试将PayPal Express Checkout集成到我的webapp(服务器端REST)中,我设法:

get create-payment working

但是,当我尝试使用沙箱测试买方帐户登录时,它是failed to process the payment.

POST请求有400个错误请求错误:

POST https://www.sandbox.paypal.com/webapps/hermes/api/batch/setbuyer 400 (Bad Request)

PayPal Express Checkout的客户端实现:

class PayPalButton extends Component {
render() {
    const Btn = paypal.Button.driver('react', {React, ReactDOM});
    const CREATE_PAYMENT_URL = `${ROOT_URL}/paypal/create-payment/${this.props.regId}`;
    const EXECUTE_PAYMENT_URL = `${ROOT_URL}/paypal/execute-payment/${this.props.regId}`;
    const token = localStorage.getItem('deotoken');

    let client = {
        sandbox: 'TO_BE_REPLACED_WITH_SANDBOX_CLIENT_ID'
    };

    let payment = () => {
  return paypal.request({
    method: 'post',
    url: CREATE_PAYMENT_URL,
    headers: {
        authorization: token
    }
  })
  .then(function(data) {
      return data.id;
  });
    };

    let onAuthorize = (data) => {
  return paypal.request({
    method: 'post',
    url: EXECUTE_PAYMENT_URL,
    headers: {
        authorization: token
    },
    json: {
                paymentID: data.paymentID,
      payerID:   data.payerID
    } 
  }).then(function() {
      // The payment is complete!
      // You can now show a confirmation message to the customer
      console.log('done');
  });
    };

return (
    <div>
    <Btn env={'sandbox'}
      client={client}
      payment={payment}
      commit={true}
      onAuthorize={onAuthorize}
    />
    </div>
);
}

我的服务器端实现):

module.exports = {
createPayment(req, res, next) {
    const { registration_id } = req.params;
    const { user } = req;

    Registration.findById(registration_id)
    .populate({ path: 'category', model: 'category' })
    .populate({ path: 'orders.meal', model: 'meal' })
    .then(reg => {
        if (reg) {
            const categoryItem = [{
                name: reg.category.name,
                sku: reg.category.name,
                price: reg.category.price,
                currency: 'MYR',
                quantity: 1
            }];
            const ordersItems = reg.orders.map(order => {
                return {
                    name: order.meal.name,
                    sku: order.meal.name,
                    price: order.meal.price,
                    currency: 'MYR',
                    quantity: order.quantity
                }
            });

            const create_payment_json = {
                intent: 'sale',
                payer: {
                    payment_method: 'paypal'
                },
                redirect_urls: {
                    return_url: 'http://localhost:8080/',
                    cancel_url: 'http://localhost:8080/'
                },
                transactions: [{
                    item_list: {
                        items: [...categoryItem, ...ordersItems]
                    },
                    amount: {
                        currency: 'MYR',
                        total: reg.totalBill
                    }
                }]
            };

            paypal.payment.create(create_payment_json, function(err, payment) {
                if (err) { 
                    next(err); 
                } else {
                    res.send(payment);
                }

            })
        } else {
            return res.status(422).send({error: 'Registration not found'});
        }
    })
    .catch(next);

},
executePayment(req, res, next) {
    const { registration_id } = req.params;
    const { paymentID, payerID } = req.body;

    const execute_payment_json = {
        payer_id: payerID
    }

    paypal.payment.execute(paymentID, execute_payment_json, function(err, paypalResponse) {
        if (err) {
            next(err);
        } else {
            if (paypalResponse.state === 'approved') {
                const payment = new Payment({
                    user: req.user._id,
                    registration: registration_id,
                    amount: paypalResponse.transactions[0].amount.total,
                    currency: paypalResponse.transactions[0].amount.currency,
                    paypalPaymentId: paypalResponse.id
                });

                payment.save()
                    .then(p => res.send(p))
                    .catch(next);
            } else {
                res.status(422).send({ error: 'Payment not approved' });
            }
        }
    });
}

};

有什么问题?我怎样才能做到这一点?

最佳答案 我遇到了同样的问题.

我已将INR设置为我的paypal沙箱中的货币,但是从API调用中将金额作为USD发送.

所以,我认为我们必须使用我们在沙盒中设置的货币进行交易.

以前的有效负载:

transactions: [{
                item_list: {
                    items: [...categoryItem, ...ordersItems]
                },
                amount: {
                    currency: 'USD',
                    total: reg.totalBill
                }
            }]

更改有效负载后:

transactions: [{
                item_list: {
                    items: [...categoryItem, ...ordersItems]
                },
                amount: {
                    currency: 'INR',
                    total: reg.totalBill
                }
            }]

更改货币后,我的代码工作正常!!
