내 Android App 용 로그인 및 등록 시스템을 만드는 방법을 배우려고합니다. 나는 그것을위한 유튜브 비디오를 따라 갔고, 나는 나의 App을 실행할 때이 에러를 계속 얻는다.org.json.JSONException : 값 <html><body><java.lang.String 유형의 스크립트를 JSONObject로 변환 할 수 없습니다.

내가 JSON 인코딩에 새로운입니다. 나는이 문제에 관한 많은 글을 읽었지만 그것을 해결하는 방법에 대한 단서는 아직 없다. 이들은 내 PHP와 자바 파일입니다.
Register.php :
<?php
$con = mysqli_connect("my_server", "my_user", "my_password", "my_database");
$username = $_POST["username"];
$password = $_POST["password"];
$statement = mysqli_prepare($con, "INSERT INTO user (username, password) VALUES (?, ?)");
mysqli_stmt_bind_param($statement, "ss", $username, $password);
mysqli_stmt_execute($statement);
$response = array();
$response["success"] = true;
echo json_encode($response);
?>
RegisterRequest.java :
package example.login;
import com.android.volley.Response;
import com.android.volley.toolbox.StringRequest;
import java.util.HashMap;
import java.util.Map;
public class RegisterRequest extends StringRequest {
private static final String REGISTER_REQUEST_URL = "http://www.vipanchith.byethost17.com/file/Register.php";
private Map<String, String> params;
public RegisterRequest(String username, String password, Response.Listener<String> listener) {
super(Method.POST, REGISTER_REQUEST_URL, listener, null);
params = new HashMap<>();
params.put("username", username);
params.put("password", password);
}
@Override
public Map<String, String> getParams() {
return params;
}
}
RegisterActivity.java : 어떤 도움을 주시면 감사하겠습니다
package example.login;

import android.os.Bundle;
import android.support.v7.app.AlertDialog;

import org.json.JSONException;
import org.json.JSONObject;
public class RegisterActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_register);
final EditText etUsername = (EditText) findViewById(R.id.etUsername);
final EditText etPassword = (EditText) findViewById(R.id.etPassword);
final Button bRegister = (Button) findViewById(R.id.bRegister);
assert bRegister != null;
bRegister.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
final String username = etUsername.getText().toString();
final String password = etPassword.getText().toString();
Response.Listener<String> responseListener = new Response.Listener<String>() {
@Override
public void onResponse(String response) {
try {
JSONObject jsonResponse = new JSONObject(response);
boolean success = jsonResponse.getBoolean("success");
if (success) {
Intent intent = new Intent(RegisterActivity.this, LoginActivity.class);
RegisterActivity.this.startActivity(intent);
} else {
AlertDialog.Builder builder = new AlertDialog.Builder(RegisterActivity.this);
builder.setMessage("Registration Failed")
.setNegativeButton("Retry", null)
.create()
.show();
}
} catch (JSONException e) {
e.printStackTrace();
}
}
};
RegisterRequest registerRequest = new RegisterRequest(username, password, responseListener);
RequestQueue queue = Volley.newRequestQueue(RegisterActivity.this);
queue.add(registerRequest);
}
});
}
}
. 고맙습니다.
json으로 구문 분석하기 전에 응답 내용을 인쇄 할 수 있습니다. 아마 오류 페이지 html 코드 – andy
