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

@Component public 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build ServerHttpRequest 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服务器之家。
