gateway全局过滤器向request header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
@Component
public class AuthSignatureFilter implements GlobalFilter, Ordered {
static Logger logger = LoggerFactory.getLogger(AuthSignatureFilter.class);
@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

此方法在新版本中已经过时 使用新方法新方法
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编程网。
