您好，我尝试使用HttpClient的将数据发送到服务器。

Hello I am trying to send data to server using httpclient.

下面是我的code

public class MainActivity extends Activity implements OnClickListener { private String TAG; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Button press = (Button) findViewById(R.id.button1); press.setOnClickListener(this); } @Override public void onClick(View v) { switch (v.getId()) { case R.id.button1: String usrName = ((EditText) findViewById(R.id.usrName)).getText() .toString().trim(); String age = ((EditText) findViewById(R.id.age)).getText() .toString().trim(); Toast.makeText(getApplicationContext(), "username:: " + usrName + "---Age::" + age, Toast.LENGTH_SHORT).show(); // Create a new HttpClient and Post Header HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost("192.168.1.40"); String resp = null; try { // create data to POST List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>( 5); nameValuePairs.add(new BasicNameValuePair("UserName", usrName)); nameValuePairs.add(new BasicNameValuePair("Age", age)); httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); // Execute HTTP Post Request HttpResponse response = httpclient.execute(httppost); resp = response.toString(); } catch (ClientProtocolException e) { System.out.println("---" + e.getMessage()); } catch (IOException e1) { System.out.println("---" + e1.getMessage()); } Log.i(TAG, "RTT inside post-data: " + time_passed); Log.i(TAG, resp.toString()); break; case R.id.send: default: break; } } }

我得到在logcat的这个错误
