自定义token校验过滤器代码实现

import lombok.extern.slf4j.Slf4j;import org.springframework.cloud.gateway.filter.GatewayFilterChain;import org.springframework.cloud.gateway.filter.GlobalFilter;import org.springframework.core.annotation.Order;import org.springframework.stereotype.Component;import org.springframework.web.server.ServerWebExchange;import reactor.core.publisher.Mono;import java.util.Arrays;import java.util.Collection;import java.util.List;import java.util.Optional;@Component@Order(-1)@Slf4jpublic class CheckAuthFilter implements GlobalFilter { @Override public Mono filter(ServerWebExchange exchange, GatewayFilterChain chain) { //校验请求头中的token List token = exchange.getRequest().getHeaders().get("token"); log.info("token的值是:" + token); if (token.isEmpty()) { return chain.filter(exchange); } // TODO token校验 return chain.filter(exchange); }}

测试

启动下面两个服务:
MallOrderApplication
MallGatewayApplication
​

然后postman发起请求
​

http://localhost:8888/order/demo01

控制台输出:

此时就打印出来你访问接口的时候header里面的token的值了, 你就可以利用这个token的值去进行校验token是否合法.
