Question

我有一个春季靴子样本，其中使用一个过滤器检查自定义标头的存在。示例代码如下：

    @Override
    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
        HttpServletRequest request = (HttpServletRequest) servletRequest;
        logger.info("insert into AuthFilter.doFilter");
        String token = request.getHeader("mid-goods-token");
        logger.info("request..");
        // check tokenÊÇ·ñÎª¿Õ
        if (StringUtils.isEmpty(token)) {
            Enumeration<String> headIndexes = request.getHeaderNames();
            while(headIndexes.hasMoreElements()) {
            	String header = headIndexes.nextElement();
            	Enumeration<String> values = request.getHeader(header);
            	log.error("Msg: {} =>{}", header, values);
            }
            return;
        }
        }

然后我开始卷曲：

curl -H“中间商品令牌：abcdef59e3b764839b912f6358558d5c;” .... http://127.0.0.1/

我得到一个令人惊讶的结果，因为token为空，而在迭代结果中确实看到了mid-goods-token标头

使用getHeader（）有什么问题吗？

无法在springboot中获取RequestHeader
