服务器读取客户端数据

    public static String GetInputStreamString(HttpServletRequest request) throws IOException {
        StringBuffer data = new StringBuffer();
        String line = null;
        BufferedReader reader = request.getReader();
        while ((line = reader.readLine()) != null)
            data.append(line);
        return data.toString();
    }

客户端一定要post请求服务器端才能接收数据。
