为什么嵌入的 Youtube 视频在上周工作时显示视频不可用？没有代码更改和 Youtube Data V3 API

Question

我正在从我的网页流式传输一堆音乐视频。

我写了一个脚本来挑选可用于流式传输的 Youtube 音乐视频。我使用 requests.get(url).json() 获取每个视频的 json 信息，然后从那里使用这行代码

if url_get.json()['items'] != [] and url_get.json()['items'][0]['status']['uploadStatus'] == "processed" and url_get.json()['items'][0]['status']['embeddable'] == "true":

决定 Youtube 视频是否可以流式传输以及我是否可以嵌入它。

但是，无论我先嵌入哪个视频，当我测试我的网页时，它都显示为视频不可用。

相同的网页代码上周实际上运行良好。剧本我一直在改。

在从我的网页嵌入和流式传输时，我没有向 Youtube 提供任何 API 密钥，所以我想知道为什么尽管检查了视频是否 "embeddable" 和 "processed".

这是我正在使用的脚本的相关部分：

#takes all files and checks if available to stream on youtube
ids = [id.strip("_arousal.csv") for id in glob.glob("*_arousal.csv")]
available_ids = []
unavailable_ids = []

for i in ids:
    url = f'https://www.googleapis.com/youtube/v3/videos?id={i}&part=status&key={your_api_key}'
    url_get = requests.get(url)
    print(url_get.json())
    if url_get.json()['items'] != [] and url_get.json()['items'][0]['status']['uploadStatus'] == "processed" and url_get.json()['items'][0]['status']['embeddable'] == "true":
        assign_score(i)
        available_ids.append(i)
    else:
        unavailable_ids.append(i)  

这是在我网页上的 Youtube 视频中加载的代码：

  //-------------------------- step 3: instantiating javascript objects, data collection

  // 2. This code loads the IFrame Player API code asynchronously.
  var tag = document.createElement('script');

  tag.src = "https://www.youtube.com/iframe_api";
  var firstScriptTag = document.getElementsByTagName('script')[0];
  firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

  // 3. This function creates an <iframe> (and YouTube player)
  //    after the API code downloads.
  var players = [];
  var i;
  function onYouTubeIframeAPIReady() {
    for (i = 0; i < num_media; i++) {
      if (document.getElementById('video_'+i.toString()) != null) {
        let end_time = 60; //show first minute, or for debugging purposes 10s
        if (randomized[i][1] < 60) {
          end_time = randomized[i][1]; //unless video is shorter than a minute
        }
        players.push(new YT.Player('video_'+i.toString(), {
          height: '315',
          width: '420',
          videoId: randomized[i][0],
          playerVars: {'controls':0, 'autoplay':0, 'fs':0, 'end': end_time},
          events: {
            'onError':onPlayerError,
            'onStateChange':onPlayerStateChange
          }
        }));
      } else {
        //music at trial i, just leave player[i] blank
        players.push(null);
      }
    }
  }

  //player.getDuration()?
  function onPlayerStateChange(event) {
    let id = event.target.getIframe().id.split("_")[1]; //string
    let num = parseInt(id, 10); //int
    let canvas = canvases[num];

    if (event.data == YT.PlayerState.ENDED) {
      clearInterval(canvas.data_collection);
      //double clearing the interval, b/c couldn't find documentation about what data_collection is set to after clearInterval
      canvas.data_collection = null;
      canvas.start_time = null;
      let stringv = "";
      let stringa = "";
      for (var i = 0; i < canvas.valences.length; i+=1) {
        stringv = stringv.concat(canvas.valences[i].join(',') + ";");
      }
      stringv.trimRight(";");
      for (var i = 0; i < canvas.arousals.length; i+=1) {
        stringa = stringa.concat(canvas.arousals[i].join(',') + ";");
      }
      stringa.trimRight(";");
      $( "#valences_"+id).attr('value', stringv);
      $( "#arousals_"+id ).attr('value', stringa);
      showSubmit(num);
    } else if (event.data == YT.PlayerState.BUFFERING) {
      clearInterval(canvas.data_collection); //don't record
      //double clearing the interval, b/c couldn't find documentation about what data_collection is set to after clearInterval
      canvas.data_collection = null;
    } else if (event.data == YT.PlayerState.PLAYING && canvas.data_collection == null) {
       //may need to check start_time and devise a timeout that would shift the sample to right times
       if (canvas.start_time == null) {
         canvas.start_time = new Date();
       }
       //setInterval doesn't record starting element, so I do that here
       canvas.valences.push([0, canvas.outputX]);
       canvas.arousals.push([0, canvas.outputY]);
       canvas.data_collection = setInterval(function(){ logKey(num); }, 500);
    } else if (event.data == YT.PlayerState.CUED) {
      //cued doesn't seem to be getting called
      canvas.start_time = new Date();
      canvas.valences.push([0, canvas.outputX]);
      canvas.arousals.push([0, canvas.outputY]);
      canvas.data_collection = setInterval(function(){ logKey(num); }, 500);
    } else if (event.data == YT.PlayerState.PAUSED) {
      //forces the user to keep watching and rating - no pauses allowed! :D
      event.target.playVideo();
    }

  }

  //throw out data if there is a player error???
  function onPlayerError() {
    let num = parseInt(event.target.getIframe().parentNode.split("_")[1], 10); //int
    let canvas = canvases[num];
    canvas.valences = [];
    canvas.arousals = [];
  }

请让我知道为什么视频仍然显示为“视频不可用”的任何建议。谢谢！

通常，当代码正在运行时，YouTube 数据 API 突然停止正常运行，最好的选择是在 Issue Tracker 中报告此类问题 - 这是因为它可能在API.

另外，如果这些视频确实不可用，您是否在浏览器中检查过？ - 有时，某些视频会更改其属性并且 API might 不会更新，或者拥有该视频的用户决定允许 (or not) 嵌入其视频。
