通过Android使用ClientLogin直接上传YouTube

我必须制作一个为特定YouTube用户上传视频的应用程序。我尝试了几个库，但不幸的是没有成功。所以，由于我想做的事情非常简单，我决定自己做，但直到现在运气都不好。我能够成功检索身份验证令牌，但无法使文件上载正常工作。这是我的密码：

    File file = new File(videoPath);
   String boundary = "f93dcbA3";
   String endLine = "\r\n";

   StringBuilder sb = new StringBuilder();
   sb.append("--");
   sb.append(boundary);
   sb.append(endLine);
   sb.append("Content-Type: application/atom+xml; charset=UTF-8"); 
   sb.append(endLine);
   sb.append(endLine);
   sb.append(entry);
   sb.append(endLine);
   sb.append("--");
   sb.append(boundary);
   sb.append(endLine);
   sb.append("Content-Type: video/3gpp");
   sb.append(endLine);
   sb.append("Content-Transfer-Encoding: binary");
   sb.append(endLine);
   sb.append(endLine);

   String bodyStart = sb.toString();

   sb = new StringBuilder();
   sb.append(endLine);
   sb.append("--");
   sb.append(boundary);
   sb.append("--");

   String bodyEnd = sb.toString();

   HttpURLConnection conn;
   try {
    FileInputStream fIn = new FileInputStream(file);
    byte fileBytes[] = new byte[(int) file.length()];
    fIn.read(fileBytes);

    conn = (HttpURLConnection) new URL("http://uploads.gdata.youtube.com/feeds/api/users/" + username + "/uploads")
      .openConnection();

    conn.setRequestMethod("POST");
             conn.setRequestProperty("Content-Type", "multipart/related; boundary=\"" + boundary + "\"");
             conn.setRequestProperty("Host", "uploads.gdata.youtube.com");
             conn.setRequestProperty("Authorization", "GoogleLogin auth=" + auth);
             conn.setRequestProperty("GData-Version", "2");
             conn.setRequestProperty("X-GData-Key", "key=" + devKey);
             conn.setRequestProperty("Slug", "video.3gp");
             conn.setRequestProperty("Content-Length", "" + (bodyStart.getBytes().length
                + fileBytes.length + bodyEnd.getBytes().length)); 
             conn.setRequestProperty("Connection", "close");

             conn.setDoOutput(true);
             conn.setDoInput(true);
             conn.setUseCaches(false);
             try {
     conn.connect();

     Log.d("ID", "" + file.length());

     try {
      OutputStream os = new BufferedOutputStream(conn.getOutputStream());

      os.write(bodyStart.getBytes());
               os.write(fileBytes);
               os.write(bodyEnd.getBytes());
               os.flush();

               String response = "";
               try {
                response = "Success! " + read(conn.getInputStream());
               } catch (FileNotFoundException e) {
                   // Error Stream contains JSON that we can parse to a FB error
                   response = "Error!" + read(conn.getErrorStream());
               }

               Log.d("ID", response);

     } catch (FileNotFoundException e1) {
      Log.d("ID", e1.getMessage(), e1);
     } catch (IOException e) {
      Log.d("ID", e.getMessage(), e);
     }
    } catch (IOException e2) {
     Log.d("ID", e2.getMessage(), e2);
    }
   } catch (MalformedURLException e3) {
    Log.d("ID", e3.getMessage(), e3);
   } catch (IOException e3) {
    Log.d("ID", e3.getMessage(), e3);
   }

以及xml条目（来自规范的简单复制粘贴）：

private static String entry=“”
+ ""
+ ""
+“糟糕的婚礼祝酒词”
+ ""
+“我在朋友的婚礼上做了一个糟糕的祝酒词。也许吧”
+ ""
+“人”
+ ""
+“敬酒，婚礼”
+ ""
+ "";

上面的代码是根据 简而言之，我收到的响应是“411长度要求”，这意味着我在标题中没有内容长度，但我有！我不知道问题出在哪里，我不知道我的代码是否正确：(

如果您能给我提供任何帮助，我将不胜感激：（

我是在Wireshark的帮助下找到的！虽然我仍然看不到它，但在我的身份验证字符串的末尾有一个新行符号。这在我的http头中添加了一个额外的行，该行不应该在那里，最后出于某种奇怪的原因，结果是“411长度必需”

因此，如果您遇到相同的错误，请尝试删除身份验证字符串中的最后一个字符。
