Question

我一直在考虑通过以下方式验证购买后直接使用Google API来奖励用户（更新Firestore上的用户数据）：

GET https://www.googleapis.com/androidpublisher/v3/applications/packageName/purchases/products/productId/tokens/token

但是授权步骤有些棘手。我如何从一个人那里获得的Cloud功能来实现它：

const functions = require('firebase-functions');
const admin = require('firebase-admin');
const {google} = require("googleapis");
const publisher = google.androidpublisher('v2');
const authClient = new google.auth.JWT({
    email: 'Service Account Email',
    key: 'BEGIN PRIVATE KEY*************END PRIVATE KEY',
    scopes: ['https://www.googleapis.com/auth/androidpublisher']
});
admin.initializeApp();

exports.validatePurchases = functions.database
    .ref('/purchases/{uId}/{orderId}')
    .onCreate((event, context) => {
        const purchase = event.val();
        if (purchase.is_processed === true) {
            console.log('Purchase already processed!, exiting');
            return null;
        }
        const orderId = context.params.orderId;
        const dbRoot = event.ref.root;
        const package_name = purchase.package_name;
        const sku = purchase.sku;
        const my_token = purchase.token;

        authClient.authorize((err, result) => {
            if (err) {
                console.log(err);
            }
            publisher.purchases.products.get({
                auth: authClient,
                packageName: package_name,
                productId: sku,
                token: my_token
            }, (err, response) => {
                if (err) {
                    console.log(err);
                }
                // Result Status must be equals to 200 so that the purchase is valid
                if (response.status === 200) {
                    return event.ref.child('is_validated').set(true);
                } else {
                    return event.ref.child('is_validated').set(false);
                }
            });
        });
        return null;
    });

请找出错误并确定是否可以使用。如何授权和部署功能？谢谢
