如何使用Youtube v3 API获取Youtube视频的mp4链接

36

我该如何在我的应用程序中使用除Youtube之外的其他来源获取完整的mp4 URL以播放视频。由于gdata / youtube API已被弃用，因此我遇到了麻烦。任何帮助将不胜感激。谢谢。

[PHP] 这个解决方案是基于最新的YouTube网站更新（2019年）的。 https://dev59.com/eLLma4cB1Zd3GeqPaWcN#55079527 - Anass

我制作了一个非常简单的API：https://gist.github.com/egyjs/9e60f1ae3168c38cc0f0054c15cd6a83

例如：YouTube视频链接：https://www.youtube.com/watch?v=YGCLs9Bt_KY

现在要获取直接链接，您需要调用API，像这样（将example.com更改为您的站点）：

https://example.com/?url=https://www.youtube.com/watch?v=YGCLs9Bt_KY

返回结果：

抱歉，您无法在Youtube API V3中完成此操作。您必须使用一个不是API的Youtube网址，但是在这里您可以获取与此相关的所有视频。 请参见http://www.youtube.com/get_video_info?&video_id='。$my_id.'&asv=3&el=detailpage&hl=en_US

或者您可以获取所有视频的下载链接，即使它是私有的或不允许您的国家 第一步：转到任何YouTube视频链接的网页https://www.youtube.com/watch?v=9mdJV5-eias 第二步：查看该页面的源代码
第三步：在第188或187行找到源JavaScript代码，其中还提供了带有mp4格式的视频的位置。
您可以通过simplehtmldom和一些php函数完成第二个想法。而使用curl可以获得第一个，这种方法相对容易，但稍微有点难以用php实现。谢谢，希望这会对您有所帮助。

对于本地到Java / Android的情况，以下是我实现此功能的方法，功劳归于@abdo-el-zahaby，我将其PHP脚本转换为等效的Java代码，它使用OkHttp客户端获取URL。

final String videoInfoUrl = "http://www.youtube.com/get_video_info?video_id=some_video_id&el=embedded&ps=default&eurl=&gl=US&hl=en";
                Request request = new Request.Builder()
                        .cacheControl(CacheControl.FORCE_NETWORK)
                        .url(videoInfoUrl)
                        .build();
                final Response response = okHttpClient.newCall(request).execute();
                InputStream inputStream = response.body().byteStream();
                BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
                String line;
                final StringBuilder contentBuilder = new StringBuilder();
                while ((line = bufferedReader.readLine()) != null) {
                    contentBuilder.append(line);
                }

                final String streamKey = "url_encoded_fmt_stream_map";
                final Map<String, String> map = new HashMap<>();
                final String content = contentBuilder.toString();
                String[] ampSplit = content.split("&");
                for (String s : ampSplit) {
                    printDivider();
                    final String[] equalsPlit = s.split("=");
                    if (equalsPlit.length >= 2) {
                        String key;
                        String value;
                        key = equalsPlit[0];
                        value = equalsPlit[1];
                        map.put(key, value);
                    }
                    printDivider();
                }
                int count = 0;
                if (map.containsKey(streamKey)) {
                    String[] streams = map.get(streamKey).split(",");
                    for (String stream : streams) {

                        String[] streamSplit = stream.split("&");
                        for (String s : streamSplit) {
                            printDivider();
                            final String urlDecoded = URLDecoder.decode(s, "UTF-8");
                            String[] details = urlDecoded.split(",");
                            for (String detail : details) {
                                System.out.println("Detail " + URLDecoder.decode(detail, "UTF-8"));
                                final String urlContent= URLDecoder.decode(detail, "UTF-8");
                                final String url = urlContent.substring(urlContent.indexOf("http"), urlContent.indexOf(";"));
                                mp4Url.put(Integer.toString(count++), url);
                            }

                        }
                        printDivider();
                    }
                }

这是我用来下载并存储到SD卡/内部存储的代码。
Request request = new Request.Builder()
              .cacheControl(CacheControl.FORCE_NETWORK)
              .url(url)
              .build();
          final Response response = okHttpClient.newCall(request).execute();
          InputStream inputStream = response.body().byteStream();
          final File newFile = new File(location);
          boolean created = newFile.createNewFile();
          System.out.println(location + " new file created: " + created);

          byte[] buff = new byte[4096];
          long downloaded = 0;
          long target = response.body().contentLength();

          System.out.println("File size is: " + Long.toString(target));
          OutputStream outStream = new FileOutputStream(newFile);
          while (true) {

            int read = inputStream.read(buff);
            if (read == -1) {
              break;
            }
            outStream.write(buff, 0, read);
            //write buff
            downloaded += read;
          }

          System.out.println("Target: " + target +", Downloaded: " + downloaded);
          outStream.flush();

这很简单，在MSEDGE中，打开网络请求面板，然后输入：

videoplayback

你会得到一个视频播放列表，进入前三个红色的视频中，选择第一个，然后复制URL，进入该URL，然后复制并粘贴出现的原始URL，就完成了！例如： https://www.youtube.com/watch?v=kyCJ17oq6kI 被翻译成 https://rr5---sn-4g5lznek.googlevideo.com/videoplayback?expire=1681055644&ei=PIsyZLKiDf2pxN8Pycma6Ac&ip=197.133.92.36&id=o-AG5C0lZuVpm9QTlY3-bdsnaxXFDmYWZNMfSnHEevldCX&itag=244&aitags=133%2C134%2C135%2C136%2C137%2C160%2C242%2C243%2C244%2C247%2C248%2C271%2C278%2C313%2C394%2C395%2C396%2C397%2C398%2C399%2C400%2C401&source=youtube&requiressl=yes&spc=99c5CQGgativKiOByrtN4P3IwKXbF2U&vprv=1&mime=video%2Fwebm&ns=GZQIER86iMv1E06YUDtOUIUM&gir=yes&clen=51126864&dur=930.629&lmt=1661735478649394&keepalive=yes&fexp=24007246&c=WEB_EMBEDDED_PLAYER&txp=5537434&n=60EJG2vTL7kL_A&sparams=expire%2Cei%2Cip%2Cid%2Caitags%2Csource%2Crequiressl%2Cspc%2Cvprv%2Cmime%2Cns%2Cgir%2Cclen%2Cdur%2Clmt&sig=AOq0QJ8wRQIhAKOA0iAqWrySUp9NpkpcxJNJQ6C1_BWfa6b91zStEu5TAiA80wiRQvGJFEd-4iuq4fjM5r7SAc1zPjr4xv6PweEgxw%3D%3D&alr=yes&cpn=pDl8mDxKkx62PK2k&cver=1.20230402.00.00&range=0-245662&rn=1&rbuf=0&pot=MmQ1aC1VTvzpGTVQZjSBWLyWnbiGJ0bOAtQgoIovIYrGI3nBfAVO60KmMbRKcRxq5ySqI9TAJ4rqBnfcuoXzj7CAgJAA24AmShxWJhrSkAoI0LrSFPC_N6FCyu6xkeOf38wpoFXa&altitags=243%2C242&redirect_counter=1&cm2rm=sn-8vq54voxxb-j5pd7d&req_id=9c5d1ec279bcda59&cms_redirect=yes&cmsv=e&mh=Yy&mm=29&mn=sn-4g5lznek&ms=rdu&mt=1681033985&mv=m&mvi=5&pl=22&lsparams=mh,mm,mn,ms,mv,mvi,pl&lsig=AG3C_xAwRQIgcOPSyxayGZHivxtPhZzhmckywIeotUdp0Ny6sepZS-4CIQD52bhTS6Xu_GOWGg_GCIIl2ZcXXaQpy-mMMzhZaB2Mbg%3D%3D。

我不知道它是如何工作的，但是看看https://podsync.net/。

当您输入YouTube播放列表链接时，它会执行一些魔法并生成一个MP4链接，供播客捕捉器使用。检查返回的XML文件，您将看到每个视频播放列表中的类似于以下行：

<enclosure url="http://podsync.net/download/[random-letters]/[video-id].mp4" length="x" type="video/mp4"></enclosure>

根据我的经验，无论你使用什么视频ID，该URL都可以正常工作。
