35 String username="username";

36 String password="password";

37 String httpUrl = "http://192.168.1.90:8080/AndroidLogin/loginAction.do?method=login";

39 //创建httpRequest对象

40 HttpPost httpRequest = new HttpPost(httpUrl);

42 List params = new ArrayList();

43 params.add(new BasicNameValuePair("username

60 if (httpResponse.getStatusLine().getStatusCode() == HttpStatus.SC_OK){

61 //取得返回的字符串

62 String strResult = EntityUtils.toString(httpResponse.getEntity());

63 resultText.setText(strResult);

}else{

65 resultText.setText("请求错误!");

66 }
