SpringCloud全局过虑器GlobalFilter的用法小结

package cn.gybank.gateway.filter;
import org.springframework.cloud.gateway.filter.GatewayFilterChain;
import org.springframework.cloud.gateway.filter.GlobalFilter;
import org.springframework.core.Ordered;
import org.springframework.http.server.reactive.ServerHttpRequest;
import org.springframework.stereotype.Component;
import org.springframework.web.server.ServerWebExchange;
import reactor.core.publisher.Mono;
@Component
public class MyGlobalFilter implements GlobalFilter, Ordered {
    @Override
    public Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) {
        ServerHttpRequest request = exchange.getRequest();
        ServerHttpRequest mutableReq = request.mutate().header("Authorization","").build();
        ServerWebExchange mutableExchange = exchange.mutate().request(mutableReq).build();
        return chain.filter(mutableExchange);
    }
    @Override
    public int getOrder() {
        return -200;
    }
}
