如何使用volley解析android中以"/“开头的Json？

dependencies {

                         Response.ErrorListener errorListener) {
        super(method, url, errorListener);
        this.listener = listener;
    }

    @Override
    protected Response<JSONObject> parseNetworkResponse(NetworkResponse response) {
        try {
            String jsonString = new String(response.data,
                    HttpHeaderParser.parseCharset(response.headers));
            // 对以"/"开头的JSON数据进行解析
            if (jsonString.startsWith("/")) {
                jsonString = jsonString.substring(1); // 去除开头的"/"
            }
            return Response.success(new JSONObject(jsonString),
                    HttpHeaderParser.parseCacheHeaders(response));
        } catch (UnsupportedEncodingException | JSONException e) {
            return Response.error(new ParseError(e));
        }
    }

    @Override
    protected void deliverResponse(JSONObject response) {
        listener.onResponse(response);
    }
}

                        // 解析成功后的处理逻辑
