错误：响应状态：PayPal Rest SDK 上的 400

Question

我在 NodeJS 的帮助下使用一些 PayPal 付款创建了一个平台，到目前为止一切正常，我不知道为什么它会抛出这个错误。 1 小时前我付款了，现在它不会让我付款。我没有修改任何代码或类似的东西。]

这是错误

/Users/calinonaca/Desktop/PEDIGREE-NOTES copy/controllers/feed.js:863 抛出错误； ^

错误：响应状态：400 在传入消息。 （/用户/calinonaca/桌面/PEDIGREE-NOTES 复制/node_modules/paypal-rest-sdk/lib/client.js:130:23) 在 IncomingMessage.emit (events.js:203:15) 在 endReadableNT (_stream_readable.js:1145:12) 在 process._tickCallback (internal/process/next_tick.js:63:19)

这是我的功能

exports.postPayment = (req,res,next) => {
    const uploadedBy = req.body.noteOwner;
    const finalprice = req.body.finalprice;
    const notename = req.body.notename;
    const loggedInUser = req.session.user._id;
    const noteprice = req.body.noteprice;




    const create_payment_json = {
        "intent": "sale",
        "payer": {
            "payment_method": "paypal"
        },
        "redirect_urls": {
            "return_url": "http://localhost/successPayment/"+finalprice+"/"+notename+"/"+uploadedBy+"/"+noteprice+"/"+loggedInUser,
            "cancel_url": "http://localhost/cancel"
        },
        "transactions": [{
            "item_list": {
                "items": [{
                    "name": "Note",
                    "sku": "001",
                    "price": finalprice,
                    "currency": "USD",
                    "quantity": 1
                }]
            },
            "amount": {
                "currency": "USD",
                "total": finalprice
            },
            "description": "Note you ordered"
        }]
    };



    paypal.payment.create(create_payment_json, function (error, payment) {
        if (error) {
            throw error;
        } else {
        for(let i = 0; i < payment.links.length; i++)
        {
            if(payment.links[i].rel === 'approval_url')
            {
                res.redirect(payment.links[i].href);
            }
        }
        }
    });

}

到目前为止一切正常，我不知道出了什么问题，你能帮帮我吗？谢谢！

只有在我复制并粘贴此对象后，我才获得带有重定向 URL 的成功响应。我希望这能帮到您。我会玩弄物体，看看有什么可以忽略的。
