您好我想对URL进行身份验证并从中获取数据。我找到了smth，但我得到以下错误。可能是什么问题？
public class MainActivity extends Activity {
private static final String URL = "https://mobilogr.uludag.edu.tr/BYService/LoginService.asmx/LoginUser";
@Override
public void onCreate(Bundle savedInstanceState) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void sendJson(View v) {
HttpClient client = new DefaultHttpClient();
HttpConnectionParams.setConnectionTimeout(client.getParams(), 10000); //Timeout Limit
HttpResponse response;
JSONObject json = new JSONObject();
try {
HttpPost post = new HttpPost(URL);
json.put("kullaniciAdi", "asdsads");
json.put("sifre", "asdasdsa");
StringEntity se = new StringEntity( json.toString());
se.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
post.setEntity(se);
response = client.execute(post);
/*Checking response */
if(response!=null){
InputStream in = response.getEntity().getContent(); //Get the data in the entity
}
} catch(Exception e) {
e.printStackTrace();
}
}
}
我收到以下错误：
