    // 返回信息

    OutputStream os = ac.getResponse().getOutputStream();
    InputStream is = response.getEntity().getContent();

    // 調用微信平台的Callback
    HttpClientCallbackResult result = new HttpClientCallbackResult(is, os);
    result.setRetCode(getStatusCode());
    try {
        callback.completed(result);
    }
