private void uploadFile(final String uploadUrl){
      new Thread(){
       public void run() {
       String end = "\r\n";
           String twoHyphens = "--";
           String boundary = "******";
           try
           {
             URL url = new URL(uploadUrl);
             HttpURLConnection httpURLConnection = (HttpURLConnection) url
                 .openConnection();
             httpURLConnection.setChunkedStreamingMode(128 * 1024);// 128K
             // 允许输入输出流
             httpURLConnection.setDoInput(true);
             httpURLConnection.setDoOutput(true);
             httpURLConnection.setUseCaches(false);
             // 使用POST方法
             httpURLConnection.setRequestMethod("POST");
             httpURLConnection.setRequestProperty("Connection", "Keep-Alive");
             httpURLConnection.setRequestProperty("Charset", "UTF-8");
             httpURLConnection.setRequestProperty("Content-Type",
                 "multipart/form-data;boundary=" + boundary);             DataOutputStream dos = new DataOutputStream(
                 httpURLConnection.getOutputStream());
             dos.writeBytes(twoHyphens + boundary + end);
             dos.writeBytes("Content-Disposition: form-data; name=\""+uploadedfile+"\"; filename=\""
                 + srcPath.substring(srcPath.lastIndexOf("/") + 1)
                 + "\""
                 + end);
             dos.writeBytes(end);
             
             FileInputStream fis = new FileInputStream(srcPath);
             byte[] buffer = new byte[8*1024]; // 8k
             int count = 0;
             // 读取文件
             while ((count = fis.read(buffer)) != -1)
             {
               dos.write(buffer, 0, count);
             }
             fis.close();             dos.writeBytes(end);
             dos.writeBytes(twoHyphens + boundary + twoHyphens + end);
             dos.flush();             InputStream is = httpURLConnection.getInputStream();
             InputStreamReader isr = new InputStreamReader(is, "utf-8");
             BufferedReader br = new BufferedReader(isr);
             String result = br.readLine();
             System.out.println(result);
             handler.sendEmptyMessage(1);
             dos.close();
             is.close();           } catch (Exception e)
           {
             e.printStackTrace();
           }
       };
      }.start();
    }这个是拼装方法
