Trying to make a request to Paypal's API using PayPal-node-SDK

尝试使用PayPal-node-SDK向Paypal的API发出请求

exports.requestPayment = functions.https.onRequest((req, res) => {
    return new Promise(function (fullfilled, rejected) {
        paypal.payment.create(create_payment_json, {}, function (error, payment) {
            if (error) {
                rejected(error);
            } else {
                console.log("Create Payment Response");
                console.log(payment);
                res.status(200).send(JSON.stringify({
                    paymentID: payment.id
                })).end();
                fullfilled(payment);
            }
        });
     });
});

but I'm constantly getting an error:

但我经常收到一个错误：

Error: getaddrinfo ENOTFOUND api.sandbox.paypal.com api.sandbox.paypal.com:443
    at errnoException (dns.js:28:10)
    at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:76:26)

Things I've tried:

我尝试过的事情：

1. Making a request to a totally different host, still ENOTFOUND
2. 向完全不同的主机发出请求，仍然是ENOTFOUND
3. Wrapping the request with cors(req,res, ()=>{...})
4. 用cors包装请求（req，res，（）=> {...}）
5. Prepending https:// to the host
6. 将https：//预先添加到主机

What is the problem?

问题是什么？
