gistfile1.txt

    public static String getsign(String fileName) {
        int minutes = 10; //分钟数
        long etime = System.currentTimeMillis() / 1000 + 60 * minutes;//
        String light = secret + "&" + etime + "&" + fileName;//secret 就是控制台你自己写的那个token 
        String sign = UpYunUtils.md5(light);// 可以替换为自己的md5转换工具类
        String sign8 = sign.substring(12, 20);
        String _upt = sign8 + etime;
        return host + fileName + "?_upt=" + _upt;

    }
