如何使用API V3获取chanel封面？

Question

我有这个js代码

$.getJSON('https://www.googleapis.com/youtube/v3/channels?part=snippet,statistics&id=UCAeWo3hCZSmoEaM-vJyzsfg&key=KEY', function(data) {
var chBnrUrl = data.items[0].brandingSettings.image.bannerImageUrl;
alert(chBnrUrl);
 });

但我不知道为什么警报中没有取出徽标？

Channel.list返回channel resource但是并非所有信息都是公开的。某些字段只能为频道所有者返回。您似乎正在使用api密钥，该密钥仅返回有关该频道的公共信息。如果您是频道的所有者，则应使用oauth2并验证此请求，然后您应该看到所有信息。

请求：

获取https://www.googleapis.com/youtube/v3/channels?part=snippet%2Cstatistics&id=UCAeWo3hCZSmoEaM-vJyzsfg&key= {YOUR_API_KEY}

响应：

你没有看到data.items[0].brandingSettings.image.bannerImageUrl;因为brandingSettings不是响应测试的一部分tryme
