GBK格式的输入流转化成字符流中文乱码

Question

            StringBuffer contentBuf = new StringBuffer();
    BufferedReader reader = null;
    try
    {
        reader = new BufferedReader(new InputStreamReader(in,“GBK”));
        char[] buf = new char[1024];
        int count = -1;
        while(true)
        {
            count = reader.read(buf);
            if(count==-1)
            {
                break;
            }
            contentBuf.append(buf,0,count);
        }
    }
    这段代码获取接口传入的参数，解析报乱码，接口传入的编码格式是GBK的，如果换成UTF-8的就不乱吗了，但是GBK解析也是乱码
