Android에서 로그인 시스템을 구현하려고하는데 String을 JsonObject으로 변환하는 중에 오류가 발생합니다. 이것은 나의 활동입니다 :오류 : 형식 java.lang.String의 치명적인 값을 JSONObject로 변환 할 수 없습니다.
public class Login extends Activity implements OnClickListener {
private EditText user, pass;
private Button mSubmit;
private ProgressDialog pDialog;
static {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
JSONParser jsonParser = new JSONParser();
private static final String LOGIN_URL = "http://sorifgroupcom.ipage.com/Android/login.php";
private static final String TAG_SUCCESS = "success";
private static final String TAG_MESSAGE = "message";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.login);
user = (EditText) findViewById(R.id.emailLogin);
pass = (EditText) findViewById(R.id.MPLogin);
mSubmit = (Button) findViewById(R.id.BtnLogin);
mSubmit.setOnClickListener(this);
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.BtnLogin:
new AttemptLogin().execute();
break;
default:
break;
}
}
class AttemptLogin extends AsyncTask<String, String, String> {
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(Login.this);
pDialog.setMessage("Attempting login...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
@Override
protected String doInBackground(String... args) {
// TODO Auto-generated method stub
// Check for success tag
int success;
String username = user.getText().toString();
String password = pass.getText().toString();
try {
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("email", username));
params.add(new BasicNameValuePair("motdepasse", password));
Log.d("request!", "starting");
// getting product details by making HTTP request
Log.i("tesssssssssssssssssssst", "test");
JSONObject json = jsonParser.makeHttpRequest(LOGIN_URL, "POST",
params);
// check your log for json response
Log.d("Login attempt", json.toString());
// json success tag
success = json.getInt(TAG_SUCCESS);
if (success == 1) {
Log.d("Login Successful!", json.toString());
// save user data
SharedPreferences sp = PreferenceManager
.getDefaultSharedPreferences(Login.this);
Editor edit = sp.edit();
edit.putString("email", username);
edit.commit();
finish();
return json.getString(TAG_MESSAGE);
} else {
Log.d("Login Failure!", json.getString(TAG_MESSAGE));
return json.getString(TAG_MESSAGE);
}
} catch (JSONException e) {
e.printStackTrace();
}
Log.i("tesssssssssssssssssssst", "test");
return null;
}
protected void onPostExecute(String file_url) {
pDialog.cancel();
if (file_url != null) {
Toast.makeText(Login.this, "", Toast.LENGTH_LONG).show();
}
}
}
내가 TextEdit에 값을 넣을 때 로그 캣 다음과 같은 오류가 출력 :

이 오류가 무엇을 의미합니까? 어떻게 해결할 수 있습니까?
