Rezorpay集成使用显示错误在CMD(Firebase云功能)

Question

我正在使用firebase云功能为我的Android应用程序使用'call'函数创建Razorpay的订单id，如下所示。但是我无法上传代码-

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();
const cors = require('cors')({origin: true});
Object.defineProperty(exports, "__esModule", { value: true });
const Razorpay = require('razorpay')
const instance = new Razorpay({ key_id: 'myKey', key_secret: 'mySecretKey' })

exports.createOrder = functions.https.onCall((data, context) => {
var options = {
amount: 50000,  // amount in paisa
currency: "INR",
receipt: "order_rcptid_11"
}; 

try{
const order = await instance.orders.create(options);
res.send(order);
}catch(e){
console.log(e);
res.status(403).send({error: 'error'});
}

});

错误是-

error  Parsing error: Unexpected token instance
events.js:200
throw er; // Unhandled 'error' event
^

这里22表示以下行

const order = await instance.orders.create(options);

有什么问题吗?我不太了解JS和NODE JS。

包。function文件夹中的Json文件

Answer 1

我认为这与await有关。不知道为什么在错误中不那么清楚，然而，await可以在异步函数中使用(参考)。所以我们有3个选项要纠正(可能更多，但这里给出3个):

1. 使函数异步添加async关键字，如下所示:

...
exports.createOrder = functions.https.onCall( async (data, context)=> {
...

2. try使用then代替await:

...
try{
instance.orders.create(options).then(order => res.send(order));
}catch(e){
...

3. 使用回调函数，就像在Razorpay的例子。

我在我这边测试了前2个，它们部署正确。我不知道这是否正常工作，因为这是我第一次看到Razorpay。但是，它部署时没有错误。
