问题描述

我试图让在用户需要登录的应用程序使用它在Android上的应用程序。登录认证将PHP Web服务来完成。我有一个 login.java CustomeHTTPClient 而这一次是一个样本code我从网上找来的。有一个在 login.java 类名 connectphp 正在连接到Web服务,并使用响应显示敬酒消息的方法

Login.java

    {
        如果(eText.getText()。的toString()。等于()||
                eText.getText()。的toString()。等于())
                {
                Toast.makeText(getApplicationContext(),填充空字段,Toast.LENGTH_SHORT).show();
                }
        其他
        {
            connectphp();
        }
        }
    公共无效connectphp()
    {
    // TODO自动生成方法存根
    ArrayList的<&的NameValuePair GT; postParameters =新的ArrayList<&的NameValuePair GT;();
    postParameters.add(新BasicNameValuePair(用户名,eText.getText()的toString()));
    postParameters.add(新BasicNameValuePair(PASS1,eText2.getText()的toString())。);
传递参数以用于身份验证的PHP Web服务
    //字符串有效=1;
    串响应=无效;
    尝试{
    响应= CustomHttpClient.executeHttpPost(http://10.0.2.2:8082/WebService/login.php,postParameters); //输入您的远程PHP,ASP,Servlet的文件链接
    字符串资源= response.toString();
    //解析度= res.trim();
    RES = res.replaceAll(\\\\ S +,);
    //error.setText(res);
    如果(res.equals(1))
    {
        Toast.makeText(getApplicationContext(),正确的用户名和密码,Toast.LENGTH_SHORT).show();
        意图I =新意图(login.this,order_pushing.class);
        startActivity(ⅰ);
    }
        其他
            如果(res.equals(0))
        {        Toast.makeText(getApplicationContext(),对不起!错误的用户名和密码,Toast.LENGTH_SHORT).show();
        }
    }赶上(例外五){    eText.setText(e.toString());
    }}
@覆盖

 eText2 =(EditText上)findViewById(R.id.editText2);
btnSubmit按钮=(按钮)findViewById(R.id.sbtn);
 btnSignup =(按钮)findViewById(R.id.signupbtn);
btnSubmit.setOnClickListener(新OnClickListener(){公共无效的onClick(视图v)
{
    验证(); (这是检查空字段)
}
});btnSignup.setOnClickListener(新View.OnClickListener(){    公共无效的onClick(查看为arg0){
    意图I =新意图(login.this,signup.class);
    startActivity(ⅰ);
    }
 });}}

这是我的 customhtpclient 类中的HTTP连接定义。

    startActivity(ⅰ);
    }
 });}}

和我的PHP Web服务名称 login.ph

 < PHP
包括(config.php文件);
//用户名和密码的形式发送

接收参数
    $名为myusername =和addslashes($ _ POST ['用户名']);

  $ =输入mypassword和addslashes($ _ POST ['PASS1']);$ SQL =SELECT * FROM注册WHERE user_ID的='$名为myusername'和密码= $输入mypassword';$结果= mysql_query($的SQL);$行= mysql_fetch_array($结果);$主动= $行['主动'];$数= mysql_num_rows($结果);

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

 如果($计数== 1)
    {回声1;(如果结果发现发送1至Android)    }
其他
    {
回声0;(如果结果没有发现Ø发送到Android)    }?>

配置文件都连接参数,建立与数据库连接的是MySQL和我使用WAMP服务器。结果
*的的config.php 的*

 < PHP$ mysql_hostname =localhost的;$ mysql_user =根;$ mysql_password =;$ mysql_database =KSE;$ BD = mysql_connect($ mysql_hostname,$ mysql_user,$ mysql_password)要么
 死(哎呀有些事情出了问题);mysql_select_db($ mysql_database,$ BD)要么死(哎呀有些事情出了问题);
?>

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


 如果(res.equals(1))
  {
      Toast.makeText(getApplicationContext(),正确的用户名和密码,Toast.LENGTH_SHORT).show();
      意图I =新意图(login.this,order_pushing.class);
      startActivity(ⅰ);
  }
      其他
          如果(res.equals(0))
      {      Toast.makeText(getApplicationContext(),对不起!错误的用户名和密码,Toast.LENGTH_SHORT).show();
      }


但是,当我给正确的信息,没有response..Please帮助我。我只是一个初学者android.If你可以做我的code改正吧。


解决方案

我忘了,从你WAMP服务器即开始我的web服务wamp- 2.and其次我删除此行$活跃= $行['主动'] ;从我的login.php和它现在所有工作

I am trying to make an app on android in which user needs to log in app to use it. log in authentication will be done by PHP web service. I have a login.java class CustomeHTTPClient and this one is an sample code I have got from internet.There is a method in login.java class name connectphp is connecting to web service and using response to display toast message

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);
    }
 });

}}

This is my customhtpclient class in which http connection define.

**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);
    }
 });

}}

And my php web service name login.ph

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


// username and password sent from Form

Receiving parameters $myusername=addslashes($_POST['username']);

$mypassword=addslashes($_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);

If result matched $myusername and $mypassword, table row must be 1 row

if($count==1)
    {

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

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

    }

?>

Config file have all connection parameters to establish connection with database that is mysql and I am using wamp server.
*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");
?>

When I am running my app it is giving me toast messgae if I'm giving wrong log in details as I use if and else here

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();
      }

But when I am giving correct information, no response..Please help me .I am just a beginner to android.If you could make corrections in my code please.

解决方案

I forgot to start my web service from thee wamp server i.e wamp- 2.and secondly i delete this line "$active=$row['active'];" from my login.php and its all working now
