spring cloud gateway全局过滤器实现向request header中放数据

exchange.getRequest().getHeaders().set();

是不能向 headers中放文件的

这时配置一个gateway全局过滤器 filter中 做了向 header放数据

@Componentpublic class AuthSignatureFilter implements GlobalFilter, Ordered { static Logger logger = LoggerFactory.getLogger(AuthSignatureFilter.class); /** * 全局过滤器 核心方法 * @param exchange * @param chain * @return */ @Override public Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) {logger.info('request = {}',JSONArray.toJSONString( exchange.getRequest()) );String token = exchange.getRequest().getQueryParams().getFirst('authToken');//向headers中放文件，记得buildServerHttpRequest host = exchange.getRequest().mutate().header('a', '888').build();//将现在的request 变成 change对象 ServerWebExchange build = exchange.mutate().request(host).build();return chain.filter(build); } @Override public int getOrder() {return -200; }}

这样发送给路由的request中就放了我们自定义的数据了

Consumer<HttpHeaders> httpHeaders = httpHeader -> { httpHeader.set('aaaa', 'bbb'); httpHeader.set('xxx', 'cc'); httpHeader.set('bbxx', 'bbbx'); httpHeader.set('aaaa', 'bbb');};ServerHttpRequest serverHttpRequest = exchange.getRequest().mutate().headers(httpHeaders).build();exchange.mutate().request(serverHttpRequest).build();

以上为个人经验，希望能给大家一个参考，也希望大家多多支持好吧啦网。
