为什么以下代码返回-1？似乎请求失败.

public static void main(String[] args)
{
    DefaultHttpClient httpClient = new DefaultHttpClient();
    HttpGet httpGet = new HttpGet("http://www.google.de");

    HttpResponse response;
    try
    {
        response = httpClient.execute(httpGet);
        HttpEntity entity = response.getEntity();
        EntityUtils.consume(entity);

        // Prints -1
        System.out.println(entity.getContentLength());
    }
    catch (ClientProtocolException e)
    {
        e.printStackTrace();
    }
    catch (IOException e)
    {
        e.printStackTrace();
    }
    finally
    {
        httpGet.releaseConnection();
    }
}

是否可以将响应作为String？
