@Component
public class AuthFilter implements GlobalFilter, Ordered {
    @Override
    public Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) {
        ServerHttpRequest request = exchange.getRequest();
        ServerHttpRequest.Builder mutate = request.mutate();
        /*获取请求头*/
        String contentType = request.getHeaders().getFirst(HttpHeaders.CONTENT_TYPE);
        /*添加、或更新*/
        mutate.header(HttpHeaders.CONTENT_TYPE, URLEncoder.encode(MediaType.APPLICATION_JSON_VALUE, Constants.UTF8));
        /*删除*/
        mutate.headers(httpHeaders -> httpHeaders.remove(name)).build();
        return chain.filter(exchange.mutate().request(mutate.build()).build());
    }

    @Override
    public int getOrder() {
        return -200;
    }
}
