spring cloud zuul配置 权限

spring-cloud 整合zuul 权限控制 token

https://blog.csdn.net/qq_19301269/article/details/78910977

作用是当所有的路由请求到后台时，过滤掉允许访问的路由后，需要一个token验证才可以访问到后台。

 

假设现在注册中心有两个服务service1 port 8001 、service2 port 8002

现在想要访问到这两个服务就需要token验证，新建一个zuul工程配置service1，service2的请求路由过滤。

 

第一步 项目中引入使用的jar包

<dependency>  
    <groupId>org.springframework.cloud</groupId>  
    <artifactId>spring-cloud-starter-zuul</artifactId>  
</dependency>

第二步 过滤器

import com.netflix.zuul.ZuulFilter;  
import com.netflix.zuul.context.RequestContext;  
import javax.servlet.http.HttpServletRequest;  
  
public class Filter extends ZuulFilter  {  
  
    /** 
     * 返回一个字符串代表过滤器的类型 
     * pre表示被路由之前 
     */  
    @Override  
    public String filterType() {  
        return "pre";  
    }  
  
    /** 
     * 过滤顺序 
     */  
  
    @Override  
    public int filterOrder() {  
        return 0;  
    }  
  
    @Override  
    public boolean shouldFilter() {  
        return true;  
    }  
  
    @Override  
    public Object run() {  
        RequestContext ctx = RequestContext.getCurrentContext();  
        HttpServletRequest request = ctx.getRequest();  
        String accessToken = String.valueOf(request.getParameter("Token"));  
        if(!accessToken.equals("zz")) {  
            ctx.setSendZuulResponse(false);  
            ctx.setResponseStatusCode(401);  
            return null;  
        }  
        return null;  
    }  
  
}  

第三步 写配置文件 将service1和service2配置路由

 

spring.application.name=Service-Gateway  
server.port=8003  
# routes to service1  
zuul.routes.service1.path=/service1/**  
zuul.routes.service1.serviceId=service1  
# routes to service2  
zuul.routes.service2.path=/service2/**  
zuul.routes.service2.serviceId=service2  
eureka.client.serviceUrl.defaultZone=http://localhost:8761/eureka/spring.application.name=Service-Gateway  
server.port=8003  
# routes to service1  
zuul.routes.service1.path=/service1/**  
zuul.routes.service1.serviceId=service1  
# routes to service2  
zuul.routes.service2.path=/service2/**  
zuul.routes.service2.serviceId=service2  
eureka.client.serviceUrl.defaultZone=http://localhost:8761/eureka/

 

第四步 过滤器书写之后就可以将这个bean引入主程序

 

import org.springframework.boot.builder.SpringApplicationBuilder;  
import org.springframework.cloud.client.SpringCloudApplication;  
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;  
import org.springframework.context.annotation.Bean;  
  
import com.zz.springcloud.zuulfilter.Filter;  
  
@EnableZuulProxy  
@SpringCloudApplication  
public class GateWayApplication {  
  
    public static void main(String[] args) {  
        new SpringApplicationBuilder(GateWayApplication.class).web(true).run(args);  
    }  
  
    @Bean  
    public Filter getFilter() {  
        return new Filter();  
    }  
  
} 

 

 

嗯，这就配置好了，easy
