YouTube使用網站的mp3轉換

我想製作的程序，可以下載YouTube視頻作爲MP3文件。我用這個網站youtube-mp3.org爲了達到目的。所以，我下載了www.youtube-mp3.org/?c#v=sTbd2e2EyTk的內容，其中sTbd2e2EyTk是視頻ID，現在我必須鏈接到mp3文件（在這種情況下爲http://www.youtube-mp3.org/get?video_id.....），但下載的內容中沒有鏈接。我注意到chrome開發人員工具（ctrl + shift + j，tab Elements）顯示chrome中的鏈接和查看源（ctrl + u）選項給了我使用java下載頁面的相同結果。我如何獲得該鏈接？我試圖使用JSoap獲取數據，但我需要的那些數據沒有立即加載到頁面上，所以我無法獲取它們。YouTube使用網站的mp3轉換

下一個代碼是用於下載網頁的內容...

URL tU = new URL("http://www.youtube-mp3.org/?c#v=sTbd2e2EyTk"); 
HttpURLConnection conn = (HttpURLConnection) tU.openConnection(); 
InputStream ins = conn.getInputStream(); 
BufferedReader rd = new BufferedReader(new InputStreamReader(ins)); 
String line; 
StringBuffer content = new StringBuffer(); 
while ((line = rd.readLine()) != null) { 
    content.append(line); 
} 
System.out.println(content.toString());

我用這個方法得到的文件，但我需要鏈接..

private static void downloadStreamData(String url, String fileName) throws Exception { 
    URL tU = new URL(url); 
    HttpURLConnection conn = (HttpURLConnection) tU.openConnection(); 

    String type = conn.getContentType(); 
    InputStream ins = conn.getInputStream(); 
    FileOutputStream fout = new FileOutputStream(new File(fileName)); 
    byte[] outputByte = new byte[4096]; 
    int bytesRead; 
    int length = conn.getContentLength(); 
    int read = 0; 
    while ((bytesRead = ins.read(outputByte, 0, 4096)) != -1) { 
     read += bytesRead; 
     System.out.println(read + " out of " + length); 
     fout.write(outputByte, 0, bytesRead); 
    } 
    fout.flush(); 
    fout.close(); 
}

我做這個使用YouTube -mp3.org。你可以在這裏看看我的代碼：YoutubeMp3

所有你需要做的是以下幾點：

DownloadManager d = new DownloadManager(); 
    d.download(YoutubeMp3.builder("http://www.youtube.com/watch?v=ebcrEqm5FFg"), "C:\\Users\\loikkk\\Music\\testDownload"); 
    d.setDownloadListener(new DownloadListener() { 

       @Override 
       public void onDownloadStart(long totalFileSize) { 
        // TODO Auto-generated method stub 

       } 

       @Override 
       public void onDownloadProcess(long currentFileSize, long totalFileSize) { 
        // TODO Auto-generated method stub 

       } 

       @Override 
       public void onDownloadFinished() { 
        // TODO Auto-generated method stub 
       } 

       @Override 
       public void onDownloadError(int arg0) { 
        // TODO Auto-generated method stub 

       } 

    });

希望它能幫助，

@hanry和Josh L：

我在Github上刪除了我的帳戶。但是，如果您使用Google Chrome，則可以從網絡角度使用開發人員控制檯。所以你可以反向設計下載鏈接這就是我已經做到的。

提交我的YouTube網址Youtube-mp-3.org
檢查從WebService
響應構建donwload鏈接自己以下這些正在使用的模式。

實施例：

YouTube網址： http://www.youtube.com/watch?v=KMU0tzLwhbE;

請求在內容主體web服務：KMU0tzLwhbE從web服務

響應：信息= { 「標題」：「開發」，「圖像」：「http://i.ytimg.com/vi/KMU0tzLwhbE/default.jpg」，「長度」：「3」，「狀態「：」serving「，」progress_speed「：」「，」progress「：」「，」ads「：」「，」pf「：」http://ping.aclst.com/ping.php/10754233/KMU0tzLwhbE?h=401301「，」h「：」e8e446dbd937a0d8f636fdc8d8bb9874「};

下載鏈接：http://www.youtube-mp3.org/get?ab=128&video_id=KMU0tzLwhbE&h=e8e446dbd937a0d8f636fdc8d8bb9874&r=1388680822878.1534658195

在GitHub上無編號:-( – Hanry

你是如何通過自己的YouTube視頻的網址，該網站以獲取此響應信息？ – Markoe7
