Android访问php取回json数据

 

PHP代码============================

$array = array(

  'username'=>'杨铸',

  'password'=>'123456',

  'user_id'=>1

);

echo json_encode($array); 
 

Java代码============================

private void startUrlCheck(String username,String password)

{

HttpClient client = new DefaultHttpClient();

StringBuilder builder = new StringBuilder();

 

HttpGet myget = new HttpGet("http://10.0.2.2/Android/index.php");

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_username = jsonObject.getString("username");

String re_password = jsonObject.getString("password");

int re_user_id = jsonObject.getInt("user_id");

setTitle("用户id_"+re_user_id);

Log.v("url response", "true="+re_username);

Log.v("url response", "true="+re_password);

} catch (Exception e) {

Log.v("url response", "false");

e.printStackTrace();

}

}

 

运行结果===================================

其中http://10.0.2.2为Android访问本机url的ip地址。对应电脑上测试的http://127.0.0.1

 

另外执行代码时会抛出异常PHP100.com

 

java.net.SocketException: Permission denied

 

此为应用访问网络的权限不足 在AndroidManifest.xml中，需要进行如下配置：

就加在

之前就好了

然后测试通过。
