在 Firebase Cloud Function 中发出 Youtube Data API 请求

Question

我的 Firebase Cloud Function 中有以下代码，它应该进行 youtube.search.list API 调用。

const admin = require('firebase-admin');
const functions = require('firebase-functions');
const {google} = require('googleapis');
const util = require('util')
const API_KEY = '<API_KEY>';

admin.initializeApp(functions.config().firebase);
const db = admin.firestore();

exports.minutely_job =
  functions.pubsub.topic('minutely-tick').onPublish((event) => {
    var urlshortener = google.urlshortener('v1');
    var youtube = google.youtube({version: 'v3', auth: API_KEY});
    var request = youtube.search.list({
        part: 'snippet',
        type: 'video',
        q: 'Helge Schneider',
        maxResults: 10
    }, (err,response) => {
        var docRef = db.collection('collection').doc('document');
        console.log(util.inspect(response, {showHidden: true, depth: null}));
        return 0;
    });
return 0;
  });

此代码不会引发错误。日志语句

console.log(util.inspect(response, {showHidden: true, depth: null}));

显示响应对象，它不包含任何预期的视频 sn-ps。

不幸的是，Log-Statement 在这里被截断了。但我没有从 response.items 中得到任何信息，所以我认为响应中不包含任何视频。

您可以使用“请求”模块代替“googleapis”模块。

const request = require('request');
const API_KEY = '************';


var url = "https://www.googleapis.com/youtube/v3/search?part=snippet&safeSearch=strict&maxResults=5&videoSyndicated=true&videoEmbeddable=true&q=Helge&type=video&key=" + API_KEY;
request(url, function (error, response, body) {
    if (!error && response.statusCode == 200) {
        obj = JSON.parse(body);
        var items = obj.items;
    }});
