Question

我正在使用 youtube_player_flutter: ^6.1.0+4 插件播放 YouTube 视频，我如何提取视频的详细信息...例如持续时间和大小

import 'package:youtube_player_flutter/youtube_player_flutter.dart';

YoutubePlayerController _youtubecontroller = YoutubePlayerController():
   YoutubePlayer(
     controller: _youtubecontroller,
     showVideoProgressIndicator: true,
   ),

Answer 1

您可以使用 YouTube 嵌入 URL 执行 http 请求并以 JSON 格式获取信息。

https://www.youtube.com/oembed?url=<youtube-video_url_here>&format=json

它包含一些信息，例如缩略图 URL、宽度、高度等。

例如：

import 'package:http/http.dart' as http;

Future<dynamic> getDetail(String userUrl) async {
    String embedUrl = "https://www.youtube.com/oembed?url=$userUrl&format=json";

    //store http request response to res variable
    var res = await http.get(embedUrl);
    print("get youtube detail status code: " + res.statusCode.toString());

    try {
      if (res.statusCode == 200) {
        //return the json from the response
        return json.decode(res.body);

      } else {
        //return null if status code other than 200
        return null;
      }
    } on FormatException catch (e) {
      print('invalid JSON'+ e.toString());
      //return null if error
      return null;
    }
  }

示例如何使用该功能：

String videoUrl = 'https://www.youtube.com/watch?v=d_m5csmrf7I';
var jsonData = await getDetail(videoUrl);
//you can take anything provided in the JSON, just change the key according to
//what is available in the response
String title = jsonData['title'];

在浏览器中打开此链接以查看您在 JSON 中获得的数据：https : //www.youtube.com/oembed? url =https : //www.youtube.com/watch?v= d_m5csmrf7I & format =json
