使用 Eclipse 连接到 wamp 服务器的 IOException 错误?

IOException error to connect to wamp server with eclipse?

我在使用我用 eclipse 制作的 android 程序连接到 WAMP server 时遇到问题....

这是我的 class:

public class Webservice {

public static String readurl(String url)
{
    try {
        HttpClient client = new DefaultHttpClient();
        HttpPost method = new HttpPost(url);

        HttpResponse response = client.execute(method);
        InputStream inputStream = response.getEntity().getContent();
        String resault = ConvertInputStream(inputStream);
        return resault;
    }
    catch (ClientProtocolException e) {
        //e.printStackTrace();
        Log.i("Log", "Protocol");
    }
    catch (IOException e) {
        //e.printStackTrace();
        Log.i("Log", "IOException");
    }

    return "read";
}


private static String ConvertInputStream(InputStream inputStream)
{
    try
    {
        BufferedReader reader = new BufferedReader(new 
        InputStreamReader(inputStream));
        StringBuilder builder = new StringBuilder();

        String line = null;

        while ((line = reader.readLine()) != null)
        {
            builder.append(line);
        }

        return builder.toString();
    }

    catch (IOException e)
    {
        e.printStackTrace();
    }
    return null;
}

}

这是我的 activity 代码:

public class NotesActivity extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    String resault = Webservice.readurl("http://localhost/note-server");
    Log.i("Log", "Resault: " + resault);

当我 运行 时,它给了我 "IOException" 因为我的 class 中的 "Log" 在 IOException 下,最后给我 "Result: read"!!!!!

我该如何解决?

如果您在模拟器上 运行,那么您应该使用 10.0.2.2 而不是 localhost
