正确获取IP与Host

说明#

  • 本文是说明,如果网关前面有一层nginx 的时候,如何获取正确的ip与端口。
  • 获取正确的之后,在插件以及选择器中,可以根据 ip,与host来进行匹配。

默认实现#

  • Apache ShenYu 网关自带实现为:org.apache.shenyu.web.forward.ForwardedRemoteAddressResolver

  • 它需要你在 nginx 设置 X-Forwarded-For,以便来获取正确的 iphost

扩展实现#

  • 新增一个类 CustomRemoteAddressResolver,实现org.apache.shenyu.plugin.api.RemoteAddressResolver
public interface RemoteAddressResolver {
    /**     * Resolve inet socket address.     *     * @param exchange the exchange     * @return the inet socket address     */    default InetSocketAddress resolve(ServerWebExchange exchange) {        return exchange.getRequest().getRemoteAddress();    }
}
  • 把你新增的实现类注册成为spring的bean,如下
   @Beanpublic RemoteAddressResolver customRemoteAddressResolver() {        return new CustomRemoteAddressResolver();        }
