Android和PHP登录认证

我想在android中创建一个应用程序，用户需要登录应用程序才能使用它。登录认证将由PHP Web服务完成。我有一个login.javaCustomeHTTPClient类和这一个是样本代码我已经从internet.There得到的是在login.java类名connectphp的方法连接到web服务，并使用响应于显示吐司消息Android和PHP登录认证

Login.java

package com.boyzcorn.android.fyp; 

import java.util.ArrayList; 
import org.apache.http.NameValuePair; 
import org.apache.http.message.BasicNameValuePair; 


import android.app.Activity; 
import android.content.Intent; 
import android.os.Bundle; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.widget.Button; 
import android.widget.EditText; 
import android.widget.Toast; 


public class login extends Activity { 
/** Called when the activity is first created. */ 
    EditText eText ; 
    EditText eText2 ; 
    Button btnSubmit ; 
    Button btnSignup ; 

    public void validation() 
    { 
     if(eText.getText().toString().equals("") || 
       eText.getText().toString().equals("")) 
       { 
       Toast.makeText(getApplicationContext(),"Fill Empty Fields",Toast.LENGTH_SHORT).show(); 
       } 
     else 
     { 
      connectphp(); 
     } 
     } 


    public void connectphp() 
    { 
    // TODO Auto-generated method stub 
    ArrayList<NameValuePair> postParameters = new ArrayList<NameValuePair>(); 
    postParameters.add(new BasicNameValuePair("username", eText.getText().toString())); 
    postParameters.add(new BasicNameValuePair("pass1", eText2.getText().toString())); 
Passing Parameter to the php web service for authentication 
    //String valid = "1"; 
    String response = null; 
    try { 
    response = CustomHttpClient.executeHttpPost("http://10.0.2.2:8082/WebService/login.php", postParameters); //Enter Your remote PHP,ASP, Servlet file link 
    String res=response.toString(); 
    // res = res.trim(); 
    res= res.replaceAll("\\s+",""); 
    //error.setText(res); 
    if(res.equals("1")) 
    { 
     Toast.makeText(getApplicationContext(),"Correct Username or Password",Toast.LENGTH_SHORT).show(); 
     Intent i = new Intent(login.this,order_pushing.class); 
     startActivity(i); 
    } 
     else 
      if(res.equals("0")) 
     { 

     Toast.makeText(getApplicationContext(),"Sorry!! Incorrect Username or Password",Toast.LENGTH_SHORT).show(); 
     } 
    } catch (Exception e) { 

    eText.setText(e.toString()); 
    }} 
@Override 
public void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 
setContentView(R.layout.login); 
eText = (EditText)findViewById(R.id.uid); 
eText2 = (EditText)findViewById(R.id.editText2); 
btnSubmit = (Button)findViewById(R.id.sbtn); 
btnSignup = (Button)findViewById(R.id.signupbtn); 
btnSubmit.setOnClickListener(new OnClickListener() { 

public void onClick(View v) 
{ 
    validation(); (This is to check empty fields) 


} 
}); 

btnSignup.setOnClickListener(new View.OnClickListener() { 

    public void onClick(View arg0) { 
    Intent i = new Intent(login.this,signup.class); 
    startActivity(i); 
    } 
}); 

}}

这是我的customhtpclient类，其中http连接定义。

**CustomHTTPClient.java** 

package com.boyzcorn.android.fyp; 

import java.util.ArrayList; 
import org.apache.http.NameValuePair; 
import org.apache.http.message.BasicNameValuePair; 


import android.app.Activity; 
import android.content.Intent; 
import android.os.Bundle; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.widget.Button; 
import android.widget.EditText; 
import android.widget.Toast; 


public class login extends Activity { 
/** Called when the activity is first created. */ 
    EditText eText ; 
    EditText eText2 ; 
    Button btnSubmit ; 
    Button btnSignup ; 

    public void validation() 
    { 
     if(eText.getText().toString().equals("") || 
       eText.getText().toString().equals("")) 
       { 
       Toast.makeText(getApplicationContext(),"Fill Empty Fields",Toast.LENGTH_SHORT).show(); 
       } 
     else 
     { 
      connectphp(); 
     } 
     } 


    public void connectphp() 
    { 
    // TODO Auto-generated method stub 
    ArrayList<NameValuePair> postParameters = new ArrayList<NameValuePair>(); 
    postParameters.add(new BasicNameValuePair("username", eText.getText().toString())); 
    postParameters.add(new BasicNameValuePair("pass1", eText2.getText().toString())); 

    //String valid = "1"; 
    String response = null; 
    try { 
    response = CustomHttpClient.executeHttpPost("http://10.0.2.2:8082/WebService/login.php",postParameters); //Enter Your remote PHP,ASP, Servlet file link 
    String res=response.toString(); 
    // res = res.trim(); 
    res= res.replaceAll("\\s+",""); 
    //error.setText(res); 
    if(res.equals("1")) 
    { 
     Toast.makeText(getApplicationContext(),"Correct Username or Password",Toast.LENGTH_SHORT).show(); 
     Intent i = new Intent(login.this,order_pushing.class); 
     startActivity(i); 
    } 
     else 
      if(res.equals("0"))//Server response if 0 
     { 

     Toast.makeText(getApplicationContext(),"Sorry!! Incorrect Username or Password",Toast.LENGTH_SHORT).show(); 
     } 
    } catch (Exception e) { 

    eText.setText(e.toString()); 
    }} 
@Override 
public void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 
setContentView(R.layout.login); 
eText = (EditText)findViewById(R.id.uid); 
eText2 = (EditText)findViewById(R.id.editText2); 
btnSubmit = (Button)findViewById(R.id.sbtn); 
btnSignup = (Button)findViewById(R.id.signupbtn); 
btnSubmit.setOnClickListener(new OnClickListener() { 

public void onClick(View v) 
{ 
    validation(); 


} 
}); 

btnSignup.setOnClickListener(new View.OnClickListener() { 

    public void onClick(View arg0) { 
    Intent i = new Intent(login.this,signup.class); 
    startActivity(i); 
    } 
}); 

}}

而且我的PHP Web服务名称login.ph

<?php 
include("Config.php"); 


// username and password sent from Form

接收参数 $名为myUsername =和addslashes（$ _ POST [ '名']）;

$mypassword=addslashes($_POST['pass1']); 

$sql="SELECT * FROM signup WHERE user_id='$myusername' and password='$mypassword'"; 

$result=mysql_query($sql); 

$row=mysql_fetch_array($result); 

$active=$row['active']; 

$count=mysql_num_rows($result);

如果结果匹配$名为myUsername和$输入mypassword，表行必须是1排

if($count==1) 
    { 

echo "1";(If result found send 1 to android) 

    } 
else 
    { 
echo "0";(If result not found send o to android) 

    } 

?>

配置文件都连接参数来建立与数据库的连接是MySQL和我使用WAMP服务器。
* 的config.php *

<?php 

$mysql_hostname = "localhost"; 

$mysql_user = "root"; 

$mysql_password = ""; 

$mysql_database = "kse"; 

$bd = mysql_connect($mysql_hostname, $mysql_user, $mysql_password) 

or 
die("Opps some thing went wrong"); 

mysql_select_db($mysql_database, $bd) 

or 

die("Opps some thing went wrong"); 
?>

当我运行我的应用程序它给我敬酒messgae如果我给错误日志中的细节，因为我用，如果与人在这里

if(res.equals("1")) 
    { 
     Toast.makeText(getApplicationContext(),"Correct Username or Password",Toast.LENGTH_SHORT).show(); 
     Intent i = new Intent(login.this,order_pushing.class); 
     startActivity(i); 
    } 
     else 
      if(res.equals("0")) 
     { 

     Toast.makeText(getApplicationContext(),"Sorry!! Incorrect Username or Password",Toast.LENGTH_SHORT).show(); 
     }

但是，当我给正确的信息，没有response..Please帮我。我只是个初学者到android.If你可以改正我的合作德请。

无关您的问题，但我必须评论其他任何人可能会遇到这从谷歌或其他地方：你应该更加注意PHP侧的SQL注入。 addslashes（）不幸的是没有足够的保护。我可能会推荐查看PHP数据对象（http://www.php.net/manual/en/book.pdo.php），特别是在准备好的语句中？ – Sean

感谢这个信息。 –

那么现在的实际问题是什么？你能详细解释一下吗？ – xDragonZ

我忘了从wamp服务器启动我的web服务，即wamp- 2.其次，我删除了这一行“$ active = $ row ['active'];”从我的login.php和它的所有工作现在
