android final 对象,android – 如何从OkHttp Response对象中提取原始JSON字符串？

private static final String URL = "http://www.livroandroid.com.br/livro/carros/carros_{tipo}.json";

public static List getCarros(Context context, String tipo) throws IOException {

String url = URL.replace("{tipo}", tipo);

OkHttpClient okHttpClient = new OkHttpClient();

Request request = new Request.Builder()

.url(URL)

.build();

Response response = okHttpClient.newCall(request).execute();

String json = response.body().toString();

List carros = parserJSON(context, json);

return carros;

}

如果我在调用getCarros方法时打印出json变量的值,我在logcat中看到以下消息：

com.squareup.okhttp.internal.http.RealResponseBody@1e11866

如何记录我收到的实际JSON字符串？
