　　先是httpPost -------------------------------------------
　　PHP CODE

<?php
header("Content-Type: text/html; charset=UTF-8");
if(isset($_POST['username']) && isset($_POST['password']))
{
$username= $_POST['username'];
$password= $_POST['password'];
if($username== "huzhangyou"&& $password== "windows")
{
$array= array( 'title'=>urlencode('登陆成功'), 'id'=>1, 'value'=>'aaaaaaaaaa');
echo urldecode(json_encode($array));
}
else
{
$array= array( 'title'=>urlencode('登陆失败'), 'id'=>1, 'value'=>md5("错误"));
echo urldecode(json_encode($array));
}
break;
}
else
{
$array= array( 'title'=>urlencode('未输入'), 'id'=>1, 'value'=>md5("错误"));
echo urldecode(json_encode($array));
}
?>
　　java Code

package socket.mft;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.ArrayList;
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.apache.http.protocol.HTTP;
import org.json.JSONObject;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
public class SocketActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//
HttpPost httpPost = new HttpPost("http://192.168.1.108/android/post.php");
HttpClient client = new DefaultHttpClient();
StringBuilder str = new StringBuilder();
ArrayList<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("username","huzhangyou"));
params.add(new BasicNameValuePair("password","windows"));   
BufferedReader buffer = null;
try
{
httpPost.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));
HttpResponse httpRes = client.execute(httpPost);
if(httpRes.getStatusLine().getStatusCode() == 200)
{
buffer = new BufferedReader(new InputStreamReader(httpRes.getEntity().getContent()));
for(String s = buffer.readLine(); s != null; s = buffer.readLine())
{
str.append(s);
}   
JSONObject json = new JSONObject(str.toString());              
String title = json.getString("title");   
int id = json.getInt("id");   
String value = json.getString("value");   
Log.d("log","Title:"+ title + " ID:"+ id + " Value:"+ value);     
}
}
catch(Exception e)      
{
if(buffer != null)
{
try
{
buffer.close();
} catch(IOException e1)
{  
// TODO Auto-generated catch block
e1.printStackTrace();
}
}
Log.d("log","服务器连接失败");
}        
//\\

}
}
　　再是http GET
　　PHP CODE

<?php
$array = array(
'sendname'=>$_GET['user'],
'username'=>'杨铸',
'password'=>'123456',
'user_id'=>1
);
echo json_encode($array);
?>
　　java Code

import java.io.IOException;
import java.io.InputStreamReader;
import java.util.ArrayList;

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.HttpGet;
import org.apache.http.client.methods.HttpPost;

public class SocketActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//
//http get(获取数据库包)
startUrlCheck("user=yangtao");
//\\

}
private void startUrlCheck(String getStr)
{
HttpClient client = new DefaultHttpClient();
StringBuilder builder = new StringBuilder();
HttpGet myget = new HttpGet("http://192.168.1.108/android/get.php?"+getStr);
try {
HttpResponse response = client.execute(myget);
BufferedReader reader = new BufferedReader(new InputStreamReader(
response.getEntity().getContent()));
for (String s = reader.readLine(); s != null; s = reader.readLine()) {

}
JSONObject jsonObject = new JSONObject(builder.toString());

} catch (Exception e) {
Log.d("log", "连接服务器失败");
e.printStackTrace();
}
