使用HttpURLConnection向CGI（ASP/PHP/JSP）发送文件

				//send to php
				URL url = new URL("http://localhost:1108/testupload/upload2.php");
				HttpURLConnection conn = (HttpURLConnection)url.openConnection();
				conn.setRequestMethod("POST");
				conn.setDoOutput(true);
				String BOUNDARY = "---------------------------7d4a6d158c9"; // 分隔符
				
				
				
				
				
				
				//DataOutputStream dos = new DataOutputStream(conn.getOutputStream());
				
				StringBuffer sb = new StringBuffer();
				sb.append("--");
				sb.append(BOUNDARY);
				sb.append("\r\n");
				sb.append("Content-Disposition: form-data; name=\"pic\"; filename=\"gggg.wav\"\r\n");
				sb.append("Content-Type: application/octet-stream\r\n\r\n");
				
				byte[] data = sb.toString().getBytes();
				byte[] end_data = ("\r\n--" + BOUNDARY + "--\r\n").getBytes();
				
				conn.setRequestProperty("Content-Type", "multipart/form-data; boundary="+BOUNDARY);
				conn.setRequestProperty("Content-Length", String.valueOf(data.length + CopyOfJDKAudioRecorder.buf.length + end_data.length));
				
				OutputStream os = conn.getOutputStream();
				os.write(data);
				os.write(CopyOfJDKAudioRecorder.buf);
				os.write(end_data);
				os.flush();
				os.close();
