java - 如何仅从 url 获取 YouTube 视频的标题？

Question

我正在用java编写一个程序，其中我的程序只给出了youtube视频的url，但我想输出url引用的视频的标题。是否有任何 API 或其他方法可以用来解决这个问题？谢谢。

Answer 1

根据官方youtube api docs 。首先，您需要获取您的 API_KEY。然后点击以下端点(使用 YOUR_API_KEY 和 YOUR_VIDEO_ID)

https://www.googleapis.com/youtube/v3/videos?id=YOUR_VIDEO_ID&key=YOUR_API_KEY
 &part=snippet,contentDetails,statistics,status

您将收到一个 JSON 对象作为响应，如下所示

{ 
  "kind": "youtube#videoListResponse",
  "etag": "\"UCBpFjp2h75_b92t44sqraUcyu0/sDAlsG9NGKfr6v5AlPZKSEZdtqA\"",
  "videos": [
      {
        "id": "7lCDEYXw3mM",
        "kind": "youtube#video",
        "etag": "\"UCBpFjp2h75_b92t44sqraUcyu0/iYynQR8AtacsFUwWmrVaw4Smb_Q\"",
        "snippet": { 
        "publishedAt": "2012-06-20T22:45:24.000Z",
        "channelId": "UC_x5XG1OV2P6uZZ5FSM9Ttw",
        "title": "Google I/O 101: Q&A On Using Google APIs",
        "description": "Antonio Fuentes speaks to us and takes questions on working with Google APIs and OAuth 2.0.",
        "thumbnails": {
        "default": {
        "url": "https://i.ytimg.com/vi/7lCDEYXw3mM/default.jpg"
     },
  "medium": {
      "url": "https://i.ytimg.com/vi/7lCDEYXw3mM/mqdefault.jpg"
  },
  "high": {
      "url": "https://i.ytimg.com/vi/7lCDEYXw3mM/hqdefault.jpg"
  }
},
   "categoryId": "28"
},
   "contentDetails": {
      "duration": "PT15M51S",
      "aspectRatio": "RATIO_16_9"
},
  "statistics": {
      "viewCount": "3057",
      "likeCount": "25",
      "dislikeCount": "0",
      "favoriteCount": "17",
      "commentCount": "12"
  },
 "status": {
    "uploadStatus": "STATUS_PROCESSED",
    "privacyStatus": "PRIVACY_PUBLIC"
   }
  }
  ]
}

您可以获得所有信息，包括标题。
