get_video_info YouTube 端点突然返回 404 未找到

Question

https://www.youtube.com/get_video_info?video_id={videoId} 正在投掷

响应状态码不表示成功：404（未找到）。

Answer 1

编辑：我发现这可行。我不知道为什么。但它确实有效。

https://www.youtube.com/get_video_info?video_id=onz2k4zoLjQ&eurl=https%3A%2F%2Fyoutube.googleapis.com%2Fv%2Fonz2k4zoLjQ&html5=1&c=TVHTML5&cver=6.20180913

您可以在url中添加&html5=1来修复它。

Answer 2

function getVideo($url)
    {
        parse_str(file_get_contents("https://www.youtube.com/get_video_info?video_id=$url&html5=1"), $data);
        return $finalData = json_decode($data['player_response'], true);
    }

    header('Content-Type: application/json');
    echo json_encode(getVideo('Zrcg7w67Ots'));

我就是这样使用它，但有时它有效，有时它不，即当它返回信息时，有时它不 你能在里面修什么吗，非常感谢

Answer 3

出于某种原因，Google 正试图让它变得更难。

2021 年 8 月编辑：

我刚刚为 C# 开发人员发布了一个新的 NuGet，它带来了 get_video_info 的 URL。享受！ https://www.nuget.org/packages/Youtube.VideoInfo

---

初始值为
https://www.youtube.com/get_video_info?video_id={videoId}&eurl=https://youtube.googleapis.com/v/{videoId}

然后添加HTML5标签：
https://www.youtube.com/get_video_info?html5=1&video_id={videoId}&eurl=https://youtube.googleapis.com/v/{videoId}

现在（2021 年 6 月）新的解决方案是：
https://www.youtube.com/get_video_info?video_id={videoId}&eurl=https%3A%2F%2Fyoutube.googleapis.com%2Fv%2Fonz2k4zoLjQ&html5=1&c=TVHTML5&cver=6.20180913

我们需要睁大眼睛。谷歌中似乎有人不喜欢 YouTube 启用此功能的事实。

Answer 4

我想我找到了 YouTube get_video_info 端点的替代方法。

下面是 CURL 和 PHP (CURL) 的实现 POST 向 youtubei/v1/player 端点发出请求，请求的标头和参数最少。

我已经从请求中删除了许多请求标头和参数，以保持简单和尽可能匿名，就像使用 GET get_video_info 端点时一样。例如 cookie、用户代理等。

下面的示例可能仍然包含可选的请求参数，因为它是在紧急情况下完成的。

在将用户代理设置为电视后，我通过检查 Firefox 中的 XHR 网络请求发现了这个新 API。

firefox-inspect-network-xhr-requests-television-user-agent

以下 CURL 请求中使用的示例视频链接：

 curl 'https://www.youtube.com/youtubei/v1/player?key=AIzaSyAO_FJ2SlqU8Q4STEHLGCilw_Y9_11qcW8' -H 'Content-Type: application/json' --data '{  "context": {    "client": {      "hl": "en",      "clientName": "WEB",      "clientVersion": "2.20210721.00.00",      "clientFormFactor": "UNKNOWN_FORM_FACTOR",   "clientScreen": "WATCH",      "mainAppWebInfo": {        "graftUrl": "/watch?v=UF8uR6Z6KLc",           }    },    "user": {      "lockedSafetyMode": false    },    "request": {      "useSsl": true,      "internalExperimentFlags": [],      "consistencyTokenJars": []    }  },  "videoId": "UF8uR6Z6KLc",  "playbackContext": {    "contentPlaybackContext": {        "vis": 0,      "splay": false,      "autoCaptionsDefaultOn": false,      "autonavState": "STATE_NONE",      "html5Preference": "HTML5_PREF_WANTS",      "lactMilliseconds": "-1"    }  },  "racyCheckOk": false,  "contentCheckOk": false}'

PHP (CURL)

function getVideoInfo($video_id){

    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, 'https://www.youtube.com/youtubei/v1/player?key=AIzaSyAO_FJ2SlqU8Q4STEHLGCilw_Y9_11qcW8');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, '{  "context": {    "client": {      "hl": "en",      "clientName": "WEB",      "clientVersion": "2.20210721.00.00",      "clientFormFactor": "UNKNOWN_FORM_FACTOR",   "clientScreen": "WATCH",      "mainAppWebInfo": {        "graftUrl": "/watch?v='.$video_id.'",           }    },    "user": {      "lockedSafetyMode": false    },    "request": {      "useSsl": true,      "internalExperimentFlags": [],      "consistencyTokenJars": []    }  },  "videoId": "'.$video_id.'",  "playbackContext": {    "contentPlaybackContext": {        "vis": 0,      "splay": false,      "autoCaptionsDefaultOn": false,      "autonavState": "STATE_NONE",      "html5Preference": "HTML5_PREF_WANTS",      "lactMilliseconds": "-1"    }  },  "racyCheckOk": false,  "contentCheckOk": false}');
    curl_setopt($ch, CURLOPT_ENCODING, 'gzip, deflate');

    $headers = array();
    $headers[] = 'Content-Type: application/json';
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

    $result = curl_exec($ch);
    if (curl_errno($ch)) {
        echo 'Error:' . curl_error($ch);
    }
    curl_close($ch);
    return $result;

}

Answer 5

更新（2021 年 7 月）

我已经尝试过这种方式

发布： https://youtubei.googleapis.com/youtubei/v1/player?key=AIzaSyAO_FJ2SlqU8Q4STEHLGCilw_Y9_11qcW8

与身体：

{
 "context": {
   "client": {
    "hl": "en",
    "clientName": "WEB",
    "clientVersion": "2.20210721.00.00",
    "mainAppWebInfo": {
        "graftUrl": "/watch?v={VIDEO_ID}"
    }
   }
  },
  "videoId": "{VIDEO_ID}"
}

这个工作就像一个魅力

Answer 6

你可以试试这个插件

new YouTubeToHtml5();

<script src="https://cdn.jsdelivr.net/gh/thelevicole/youtube-to-html5-loader@4.0.1/dist/YouTubeToHtml5.js"></script>
<video data-yt2html5="https://www.youtube.com/watch?v=ScMzIvxBSi4" controls></video>

Answer 7

尝试 1060 修复 - 此问题尚未在 Pytube 包中修复。在 Pytube 正式可用之前，您可以在系统中安装以下一个以进行下载工作。 https://github.com/Zeecka/pytube/tree/fix_1060

更多详情可以参考https://github.com/pytube/pytube/issues/1060

Answer 8

Youtube （在 2021 年 8 月 8 日撰写本文时） 看起来已将等效输出移至 watch?v= 端点。您应该在它返回的 html 中的 ytInitialPlayerResponse (json) 变量中找到视频格式。

例如https://youtube.com/watch?v=SA8ZBJWo73E 返回 html。在该 html 响应中，ytInitialPlayerResponse 变量包含一个 json 字符串。在该字符串中，您可以在以下位置找到视频格式：[streamingData][formats]。

我很想把所有功劳都归功于这个例子 commit 是我找到答案的地方。

Answer 9

这就是我现在获取 youtube 流数据格式的方式。也许它可以帮助某人。

var videoInfoUrl =  $"https://www.youtube.com/watch?v={videoId}";
using (var client = new HttpClient())
{
  var videoPageContent = await client.GetStringAsync(videoInfoUrl);

  var regex = new Regex(@"ytInitialPlayerResponse\s*=\s*(\{.+?\})\s*;", RegexOptions.Multiline);
  var match = regex.Match(videoPageContent);

  if (!match.Success)
     return "";

  var json = match.Result("$1");

  var playerResponseJson = JToken.Parse(json);
  var formats = playerResponseJson.SelectToken("streamingData.formats").ToList();
}

Answer 10

到目前为止，对于需要来自get_video_info API 的数据的 Python 项目，我发现的最佳解决方案似乎是使用来自pytube project 的the InnerTube API：

>>> from pytube.innertube import InnerTube
>>> innertube = InnerTube()
>>> video_info = innertube.player("dQw4w9WgXcQ")
>>> video_info.keys()
dict_keys(['responseContext', 'trackingParams', 'adBreakParams', 'playabilityStatus', 'streamingData', 'playbackTracking', 'videoDetails', 'annotations', 'playerConfig', 'storyboards', 'attestation', 'videoQualityPromoSupportedRenderers', 'messages', 'endscreen', 'playerSettingsMenuData'])
>>> video_info["videoDetails"]
