我正在使用以下代码来获取服务器响应的字符串表示形式。问题是它在尝试传递 response 时抛出了内存不足异常toString()。此代码在 Android 上运行。

String resp = IOUtils.toString(resEntity.getContent(), "UTF-8");

HttpGet httpGet = new HttpGet(url);
httpGet.setHeader("Content-Type", "application/json");
httpGet.setHeader("Accept", "JSON");

HttpResponse httpResponse = httpclient.execute(httpGet);
HttpEntity resEntity = httpResponse.getEntity();
if (resEntity != null) {
  //String resp = EntityUtils.toString(resEntity);
  String resp = IOUtils.toString(resEntity.getContent(), "UTF-8"); // exception here
  Log.i(TAG, resp);
// ........
// gosn parser code here
// ........
}

堆栈跟踪是：
