Fetching Correct IP Address And Host


  • This doc demonstrates how to get correct IP address and host when Apache ShenYu serves behind nginx reverse proxy.
  • After fetched real IP and host, you can match them with plugins and selectors.

Default Implementation#

  • The embedded implementation in Apache ShenYu is :org.apache.shenyu.web.forward.ForwardedRemoteAddressResolver.

  • You need to config X-Forwarded-For in nginx first to get correct IP address and host.

Implement through a Plugin#

  • Declare a new class named CustomRemoteAddressResolver and implements 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();    }
  • Register defined class as a Spring Bean.
   @Bean   public SignService customRemoteAddressResolver() {         return new CustomRemoteAddressResolver();   }
