Youtube搜索API没有'；t返回sd/max分辨率缩略图

我正在使用youtube api v3搜索视频。以下是一个例子：

GET https://www.googleapis.com/youtube/v3/search?part=snippet&maxResults=10&q=taylor+swift&type=video&key={YOUR_API_KEY}

在搜索结果中，我获得了以下缩略图信息：

...
"title": "Taylor Swift - Delicate",
"thumbnails": {
 "default": {
  "url": "https://i.ytimg.com/vi/tCXGJQYZ9JA/default.jpg",
  "width": 120,
  "height": 90
 },
 "medium": {
  "url": "https://i.ytimg.com/vi/tCXGJQYZ9JA/mqdefault.jpg",
  "width": 320,
  "height": 180
 },
 "high": {
  "url": "https://i.ytimg.com/vi/tCXGJQYZ9JA/hqdefault.jpg",
  "width": 480,
  "height": 360
 }
},
...

"title": "Taylor Swift - Delicate",
"thumbnails": {
 "default": {
  "url": "https://i.ytimg.com/vi/tCXGJQYZ9JA/default.jpg",
  "width": 120,
  "height": 90
 },
 "medium": {
  "url": "https://i.ytimg.com/vi/tCXGJQYZ9JA/mqdefault.jpg",
  "width": 320,
  "height": 180
 },
 "high": {
  "url": "https://i.ytimg.com/vi/tCXGJQYZ9JA/hqdefault.jpg",
  "width": 480,
  "height": 360
 },
 "standard": {
  "url": "https://i.ytimg.com/vi/tCXGJQYZ9JA/sddefault.jpg",
  "width": 640,
  "height": 480
 },
 "maxres": {
  "url": "https://i.ytimg.com/vi/tCXGJQYZ9JA/maxresdefault.jpg",
  "width": 1280,
  "height": 720
 }
},

但是，如果我手动更改链接，我可以看到视频的

标准

和

maxres

缩略图也存在-

为什么我没有在搜索结果中得到这些信息？我能做些什么呢？

这似乎是一个你应该做的错误

您的搜索查询仅返回该视频的3个缩略图，但如果您执行视频请求

https://www.googleapis.com/youtube/v3/videos?part=snippet&id=tCXGJQYZ9JA&key={YOUR_API_KEY}

它将返回所有5个缩略图：
