最近在开发Android软件中，要实现手机端向服务器端提交数据，打算采用Android post请求，向服务器端传递字节流，故而写了一个代码原型，代码如下：
@Override public void onCreate(Bundle savedInstanceState) {     super.onCreate(savedInstanceState);     setContentView(R.layout.main);     post(getData(), "http://www.android-study.com"); } public byte[] getData() {     ByteArrayOutputStream arrayOutputStream = new ByteArrayOutputStream();     DataOutputStream dataOutputStream = new DataOutputStream(arrayOutputStream);     try {         dataOutputStream.writeShort(8);         dataOutputStream.writeUTF("wangjun");         dataOutputStream.flush();         dataOutputStream.close();     } catch (Exception e) {         throw new RuntimeException(e);     }     return arrayOutputStream.toByteArray(); } public boolean post(byte[] paramArrayOfByte,String http) {     ByteArrayEntity arrayEntity = new ByteArrayEntity(paramArrayOfByte);     arrayEntity.setContentType("application/octet-stream");     HttpPost httpPost = new HttpPost(http);     httpPost.setEntity(arrayEntity);     DefaultHttpClient client = new DefaultHttpClient();     try {         int result=client.execute(httpPost).getStatusLine().getStatusCode();         Log.i("huilurry","]]]=" + result);     } catch (Exception e) {         throw new RuntimeException(e);     }     return false; }

这又是啥啊？看不懂、
