PayPal Express签出的我的客户端实现：

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>
);
}

})

问题是什么？我怎样才能做到这一点呢？

我也面临同样的问题。 我在paypal沙箱中将印度卢比设置为我的货币，但从API调用发送的金额为美元。 所以，我认为我们必须用我们在沙箱中设定的货币进行交易

以前的有效载荷：

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

更改有效载荷后：

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

我也犯了同样的错误。你找到解决这个问题的办法了吗？请分享。

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