Spring Cloud Zuul 添加 ZuulFilter

紧接着上篇随笔Spring Cloud Zuul写,添加过滤器,进行权限验证

1.添加过滤器

package com.dzpykj.filter;

import java.io.IOException;

import javax.servlet.http.HttpServletRequest;

import org.springframework.stereotype.Component;

import com.netflix.zuul.ZuulFilter;

import com.netflix.zuul.context.RequestContext;

@Component

public class AccessFilter extends ZuulFilter {

    @Override

    public String filterType() {

        return "pre";

    }

    @Override

    public int filterOrder() {

        return 0;

    }

    @Override

    public boolean shouldFilter() {

        return true;

    }

    @Override

    public Object run() {

        RequestContext ctx = RequestContext.getCurrentContext();

        HttpServletRequest request = ctx.getRequest();

        Object accessToken = request.getParameter("accessToken");

        if (request.getRequestURI().contains("myOrder")) {

            if (accessToken == null) {

                ctx.setSendZuulResponse(false);

                ctx.setResponseStatusCode(401);

                try {

                    ctx.getResponse().getWriter().write("You are unauthorized");

                } catch (IOException e) {

                    e.printStackTrace();

                }

                return null;

            }

        }

        return null;

    }

}
