无法通过.php文件连接wamp服务器和Android应用程序

Question

我不太了解android，因为我正在开发一个Android应用程序，我想首先访问我的数据库来完成一个登录功能。我使用eclipse，wamp服务器和一点点php。

这是我的java类：

 package com.example.marketapp;

import java.io.IOException;
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.Map;

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicNameValuePair;
import org.json.JSONObject;

import android.support.v7.app.ActionBarActivity;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
import android.view.View.OnClickListener;

public class Login extends ActionBarActivity implements OnClickListener{

    EditText EmailAdresst, Passwordt;
    Button blogin,btnregister;

    String email, password;

    HttpClient httpclient;

    HttpPost httppost;

    ArrayList<NameValuePair> nameValuePairs;

    HttpResponse response;
    HttpEntity entity;
    private static InputStream is;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);

        initialise();

    }
        private void initialise(){

    EmailAdresst = (EditText) findViewById(R.id.EmailAdresst);
    Passwordt = (EditText) findViewById(R.id.Passwordt);

    blogin = (Button) findViewById(R.id.btnlogin);
   // btnregister = findViewById(R.id.btnregister);

    blogin.setOnClickListener(this);
    //btnregister.setOnClickListener(this);
        }

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub

            httpclient = new DefaultHttpClient();

            httppost = new HttpPost("http://127.0.0.1/test/index.php");

            email = EmailAdresst.getText().toString();
            password = Passwordt.getText().toString();


        try{
            //Create new Array List
            nameValuePairs = new ArrayList<NameValuePair>();

            //Place them in an array List
            nameValuePairs.add(new BasicNameValuePair("email",email));
            nameValuePairs.add(new BasicNameValuePair("password",password));

            //Add array list to http post
            httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

            //assign executed from container to response
        response = httpclient.execute(httppost);

        if (response.getStatusLine().getStatusCode()==200){

            entity = response.getEntity();

            if(entity != null){

                InputStream instream = entity.getContent();
                JSONObject jsonResponse =new JSONObject (convertStreamToString(instream));

                String retmail = jsonResponse.getString("mail");
                String retpass = jsonResponse.getString("pass");

                //validate login
                if(email.equals(retmail)&& password.equals(retpass)){
                    //Create a new shared preference by getting the preference
                    //Give the shared preference any name you like
                    SharedPreferences sp = getSharedPreferences("Logindetails",0);

                    //Edit the Shared Preference
                    SharedPreferences.Editor spedit = sp.edit();

                    //Put the login details as strings
                    spedit.putString("mail", email);
                    spedit.putString("pass", password);

                    //Close the editor
                    spedit.commit();

                    //Display a Toast saying login was a success
                    Toast.makeText(getBaseContext(), "SUCCESS!", Toast.LENGTH_SHORT).show();

                }else{
                    //display a toast saying it failed.
                    Toast.makeText(getBaseContext(), "Invalid Login Details", Toast.LENGTH_SHORT).show();
                }
            }
        }
        }catch(Exception e){
            e.printStackTrace();
            //Display toast when there is a connection error
            Toast.makeText(getBaseContext(), "Connection Error", Toast.LENGTH_SHORT).show();
        }

        }
        private static String convertStreamToString(InputStream instream) {
              BufferedReader reader = new BufferedReader( new InputStreamReader(is));
                StringBuilder sb = new StringBuilder();

                String line = null;
                {
                try{
                    while ((line = reader.readLine()) !=null){
                        sb.append(line + "\n");
                    }
                }catch (IOException e){
                    e.printStackTrace();
                }finally{
                    try{

</LinearLayout>

这是我的清单文件：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.marketapp"
    android:vesionCode="1"

    <uses-permission android:name="android.permission.INTERNET" />
    <application
        android:allowBackup="true"
        android:icon="@drawable/offer"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity

            <intent-filter>

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".UserPage">
        </activity>
        <activity
            android:name=".Login">
        </activity>
            <!--  account Activity -->
        <activity android:name=".AccountActivity" />
         
        <!--  General Offers Activity -->
        <activity android:name=".GenOffers" />
         
        <!--  Personal Offers Activity -->
        <activity android:name=".PersonOffers" />
 
        <activity
            android:name=".changePassword">
        </activity>
    </application>
</manifest>




And here is my index.php file:

    <?php

        error_reporting(E_ALL ^ E_DEPRECATED);
        error_reporting(E_ALL ^ E_NOTICE ^ E_WARNING);
        error_reporting(E_ERROR | E_PARSE);

        $dbhost="localhost";
        $dbuser="root";
        $dbpass="";
        $dbdb="market";

        $connect = mysql_connect($dbhost, $dbuser, $dbpass) or die("connection error");

        mysql_select_db($dbdb) or die ("database selection error");

        $email =$_POST['email'];
        $password =$_POST['password'];

        $query= mysql_query("SELECT * FROM users WHERE email='$email' AND password='$password'");

        $num = mysql_num_rows($query);

        if ($num==1){

            while($list=mysql_fetch_assoc($query))
                {
                    $output =$list;
                    echo json_encode($output);
                }
                mysql_close();
            }
    ?>

我在phpmyadmin中创建了一个名为“market”的数据库和一个包含2个字段“email”和“password”以及3个记录的表用户。我在eclipse的模拟器上运行应用程序没有错误，当我放置一个记录并单击登录按钮时总是得到“连接错误”。据我所知，这是一个数据库问题。有什么建议吗？
