android > android 客户端 ,PHP 服务器端 HttpGet类和HttpPost类

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

package socket.mft;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStreamReader;import java.util.ArrayList;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.HttpGet;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);                //       //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()) {    builder.append(s);    }    JSONObject jsonObject = new JSONObject(builder.toString());    String re_sendname = jsonObject.getString("sendname");    String re_username = jsonObject.getString("username");    String re_password = jsonObject.getString("password");    int re_user_id = jsonObject.getInt("user_id");    Log.d("log", "sendname:"+re_sendname+",name:"+re_username+",pwd:"+re_password+",id:"+re_user_id);    } catch (Exception e) {    Log.d("log", "连接服务器失败");    e.printStackTrace();    }    }    }
