我使用的服务是：识别-REST_API

调用的接口是：识别-REST_API

参数设置情况：

        JSONObject params = new JSONObject();

        params.put("format", "pcm");

        params.put("rate", 8000);

        params.put("channel", "1");

        params.put("token", token);

        params.put("cuid", cuid);

        params.put("len", pcmFile.length());

        params.put("speech", DatatypeConverter.printBase64Binary(loadFile(pcmFile)));

        // add request header

        conn.setRequestMethod("POST");

        conn.setRequestProperty("Content-Type", "application/json; charset=utf-8");

        conn.setDoInput(true);

        conn.setDoOutput(true);

        // send request

        DataOutputStream wr = new DataOutputStream(conn.getOutputStream());

        wr.writeBytes(params.toString());

        wr.flush();

        wr.close();

        printResponse(conn);

开发平台和机型：window

SDK版本号：

复现步骤、现象及其他描述：printResponse返回乱码，返回流读取出来的字符串是UTF-8,转码GB2312也是乱码
