完整代码 ：

• 我正在尝试创建一个 API 来读取 YouTube 数据并写入 在我的网站上对我说，如果那个人在心里，但它 总是给我这样的错误

  var express = require('express'(; var app = express((; var bodyParser = require('body-parser'(; var request = require('request'(;

  //Configure app to use bodyParser();
  app.use(bodyParser.urlencoded({ extend: true}));
  app.use(bodyParser.json());
  var port = process.env.PORT || 1337;
  //Routes for the API
  var router = express.Router();
  router.use(function(req, res, next) {
  console.log("Got Request"); // -> Something is happening
  next();
  })
  var API_KEY= '';
  CHANNEL_ID = 'UCmDM6zuSTROOnZnjlt2RJGQ';
  router.get('/', function(req, res) {
  request.get('https://www.googleapis.com/youtube/v3/search', { part:         'snippet', channelId: CHANNEL_ID, type: 'video', eventType: 'live', key: API_KEY         }, function(data) {
  try {
  if(data['items'].length > 0) 
  res.json({status: true});
  }
  catch (err) {
  res.json({status: false});
  console.log(err)
  }
  });
  });
  //Custom URL e.g. example.com:1337/api/ECHO
  router.route('/:echo').get(function(req, res) {
  res.json({echo: req.params.echo});
  })
  
  //All routes will be prefixed with /api
  app.use('/api', router);
  
  //Start the server
  app.listen(port);
  console.log('API server has been started on port ' + port);

错误在此行

if(data['items'].length > 0) 

数据对象没有"项"属性。执行数据对象的控制台.log以查看返回的内容。看起来 Youtube API 未正确调用并返回错误。

请改为在请求中尝试以下代码：

request({url: "https://www.googleapis.com/youtube/v3/search?",
qs:{ 
part: 'snippet', 
channelId: CHANNEL_ID, 
type: 'video', 
eventType: 'live', 
key: API_KEY
}
}, function(err, response, data){
if (err){
console.log(err);
}
console.log(data);
if(data['items'].length > 0) {
res.json({status: true});
}
});
