今天有个朋友咨询我一个问题，截图如下：

在忙完了自己的事情后，我也简单的看了下，然后写了一个Filter来实现这位朋友说的功能，其实就是想记录请求的参数信息，下面我把涉及到的请求都打印了一遍，当然日志格式你可以自定义。

输出日志的Filter

public class DebugRequest extends ZuulFilter {
    @Override
    public String filterType() {
        return "pre";
    }
    @Override
    public int filterOrder() {
        return 1;
    }
    @Override
    public boolean shouldFilter() {
        return true;
    }
    @Override
    public Object run() {
        HttpServletRequest req = (HttpServletRequest)RequestContext.getCurrentContext().getRequest();
        System.err.println("REQUEST:: " + req.getScheme() + " " + req.getRemoteAddr() + ":" + req.getRemotePort());
        System.err.println("REQUEST:: " + req.getScheme() + " " + req.getRemoteAddr() + ":" + req.getRemotePort());
        StringBuilder params = new StringBuilder("?");
        Enumeration<String> names = req.getParameterNames();
        if( req.getMethod().equals("GET") ) {
           while (names.hasMoreElements()) {
              String name = (String) names.nextElement();
              params.append(name);
              params.append("=");
              params.append(req.getParameter(name));
              params.append("&");
              }
        }
        if (params.length() > 0) {
            params.delete(params.length()-1, params.length());
        }
        System.err.println("REQUEST:: > " + req.getMethod() + " " + req.getRequestURI() + params + " " + req.getProtocol());
        Enumeration<String> headers = req.getHeaderNames();
        while (headers.hasMoreElements()) {
            String name = (String) headers.nextElement();
            String value = req.getHeader(name);
            System.err.println("REQUEST:: > " + name + ":" + value);
        }
        final RequestContext ctx = RequestContext.getCurrentContext();
        if (!ctx.isChunkedRequestBody()) {
            ServletInputStream inp = null;
            try {
                inp = ctx.getRequest().getInputStream();
                String body = null;
                if (inp != null) {
                    body = IOUtils.toString(inp);
                    System.err.println("REQUEST:: > " + body);
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        return null;
    }
}
