Javascript 如何使用API V3获得香奈儿封面？

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);
 });

但我不知道为什么不在警报中获取徽标？

返回一个标记，但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。您似乎正在使用一个api密钥，该密钥只返回有关频道的公共信息。如果您是通道的所有者，您应该使用oauth2并验证此请求，那么您应该看到所有信息

请求：

获取{YOUR_API_KEY}

您没有看到数据。项[0]。brandingSettings.image.bannerImageUrl；因为brandingSettings不是响应测试的一部分，所以我犯了一个错误，正确的链接是您仍在使用API密钥，因此不会更改它不是公共数据验证您的用户并重试
