火力基地功能真的很慢

Question

我在使用Firebase函数时遇到问题，使用管理员api读取然后写入Firestore。

请参阅下面的代码：

我已经评论了 2 个控制台日志，执行需要 2-5 分钟。Firestore 中的数据集很小(只有几条记录(。 请对我明显做错什么提出任何建议？

谢谢

(根据要求使用其余代码进行编辑。这是直接取自 Stripe 的 github 示例(

const processTheOrderApp = express();
processTheOrderApp.post(
'/',
bodyParser.raw({ type: 'application/json' }),
(
request: { headers: { [x: string]: any }; rawBody: any },
response: {
status: (
arg0: number
) => { (): any; new (): any; send: { (arg0: string): any; new (): any } };
json: (arg0: { received: boolean }) => void;
}
) => {
const sig = request.headers['stripe-signature'];
let event;
try {
event = stripe.webhooks.constructEvent(request.rawBody, sig, endpointSecret);
} catch (err) {
console.log(err);
return response.status(400).send(`Webhook Error: ${err.message}`);
}
// Handle the checkout.session.completed event
if (event.type === 'checkout.session.completed') {
const session = event.data.object;
addPaymentDataToOrder(session); // Here we can proccess the order data after successfull payment
// (e.g. change payment status in Firebase Database and call another function)
}
// Return a response to acknowledge receipt of the event
response.json({ received: true });
}
);
// Exporting our http function
exports.processTheOrder = functions.https.onRequest(processTheOrderApp);

function addPaymentDataToOrder(session: any) {
console.log('adding payment'); ////between this console log
admin
.firestore()
.collection('orders')
.where('paymentSessionId', '==', session.id)
.limit(1)
.get() // getting the order which matches the session id, should be only one so limited to one result
.then((query: any) => {
console.log('found item');  ////and this console log
const thing = query.docs[0];
var orderDoc = thing.data();
thing.ref.update({
checkedOut: true,
payment: session,
});
});
}

它很慢，因为如果 Firebase 云函数中的函数在 2 分钟内未被调用/调用，它将进入冷启动状态。查看此参考。 https://medium.com/@siriwatknp/cold-start-workaround-in-firebase-cloud-functions-8e9db1426bd3
