推荐答案

请记住，您的依赖性占用空间将影响部署和冷启动时间.这是我使用 https.get() 和

Keep in mind that your dependency footprint will affect deployment and cold-start times. Here's how I use https.get() and functions.config() to ping other functions-backed endpoints. You can use the same approach when calling 3rd party services as well.

const functions = require('firebase-functions');
const https = require('https');
const info = functions.config().info;

exports.cronHandler = functions.pubsub.topic('minutely-tick').onPublish((event) => {
    return new Promise((resolve, reject) => {
        const hostname = info.hostname;
        const pathname = info.pathname;
        let data = '';
        const request = https.get(`https://${hostname}${pathname}`, (res) => {
            res.on('data', (d) => {
                data += d;
            });
            res.on('end', resolve);
        });
        request.on('error', reject);
    });
});
