简介

网关的作用

网关可以拦截客户端所有请求，对该请求进行权限控制，负载均衡，日志管理，接口调用监控等。

网关与过滤器的区别

过滤器是拦截单个tomcat服务器进请求，网关是拦截整个微服务所有请求。

网关和Nginx的区别

1. 相同点：Zuul和Nginx都可以实现负载均衡，反向代理，过滤请求，实现网关效果。
2. 不同点：Nginx采用C语音编写，Zuul采用java语音编写。Zuul负载均衡实现：采用Ribbon+Eureka实现本地负载均衡。Nginx实现负载均衡：采用服务器端实现负载均衡。

zuul网关实现反向代理

新建springcloud-zuul-gateway 模块

• AppGateway 启动类

package com.baba.wlb;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;
/**
* @Author wulongbo
* @Date 2021/1/28 11:52
* @Version 1.0
*/@SpringBootApplication
@EnableEurekaClient
@EnableZuulProxy
public class AppGateway {
//@EnableZuulProxy 开启网关代理
public static void main(String[] args) {
SpringApplication.run(AppGateway.class, args);
}
}

启动服务

依次Eureka Server、Zuul网关、Member服务、Order服务
访问订单接口：http://localhost:8200/getOrderByMember?name=11

再访问网关：http://localhost/api-order/getOrderByMember?name=11

实现了反向代理！
