这是我的android代码，使用task1连接到我的数据库。任何人都可以帮我解决我的问题。感谢大家。它也适用于localhost。：）

的Android

package com.example.kun.carkila;

import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

import com.kosalgeek.genasync12.AsyncResponse;
import com.kosalgeek.genasync12.PostResponseAsyncTask;

import java.util.HashMap;

public class MainActivity extends AppCompatActivity implements View.OnClickListener {
final String LOG = "MainActivity";
Button btnLogin;
EditText etUsername,etPassword;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    etUsername = (EditText)findViewById(R.id.etUsername);
    etPassword = (EditText)findViewById(R.id.etPassword);
    btnLogin = (Button)findViewById(R.id.btnLogin);
    btnLogin.setOnClickListener(this);

}
@Override
public void onClick(View v) {
    HashMap postData = new HashMap();
    String username = etUsername.getText().toString();
    String password = etPassword.getText().toString();
    postData.put("username",username);
    postData.put("password", password);

    PostResponseAsyncTask task1 = new PostResponseAsyncTask(MainActivity.this, postData,
            new AsyncResponse() {
        @Override
        public void processFinish(String s) {
            try {
                if (s.contains("renterowner")) {
                    Toast.makeText(MainActivity.this, "Renter Login Successful!", Toast.LENGTH_SHORT).show();
                    Intent in = new Intent(MainActivity.this, ListActivity.class);
                    startActivity(in);

                } else if (s.contains("ownerrenter")) {
                    Toast.makeText(MainActivity.this, "Owner Login Successful!", Toast.LENGTH_SHORT).show();
                    Intent in = new Intent(MainActivity.this, ownerhome.class);
                    startActivity(in);
                } else {
                    Toast.makeText(MainActivity.this, "Login Failed!", Toast.LENGTH_SHORT).show();
                }

            }
        catch (Exception e) {
            System.out.print("Error: " + e.toString());
        }
        }
                });
    task1.execute("http://carkila.esy.es/index.php");
}
}

每当我在我的机器人上键入正确的登录信息时，它总是以我的else语句结束，但是当我使用http://carkila.esy.es/index.php登录我的网络时，它正在工作。

数据库的config.php

<?php
// define database related variables
$database = '*****';
$host = '*****';
$user = '*****';
$pass = '*****';

// try to conncet to database
$dbh = new PDO("mysql:dbname={$database};host={$host}", $user, $pass);
return $dbh;


try{
if(!$dbh){

  echo "unable to connect to database";
 }
}catch (PDOException $e){
echo $e->getMessage();
}

?>

的index.php

<?php 

$errors = array(
  1=>"Invalid user name or password, Try again",
  2=>"Please login to access this area"
);

$error_id = isset($_GET['err']) ? (int)$_GET['err'] : 0;

if ($error_id == 1) {
   echo $errors[$error_id];

   }elseif ($error_id == 2) {
   echo $errors[$error_id];
  }
?>

authenticate.php

答案 0 :(得分：0)

您正在将请求发送到错误的页面。您的index.php不是负责处理POST数据的人，authenticate.php。

所以，改变你的代码：

task1.execute("http://carkila.esy.es/index.php");

为：

task1.execute("http://carkila.esy.es/authenticate.php");
