Fetching correct IP address and host

description

• This doc demonstrates how to get correct IP address and host when soul 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 soul is :org.dromara.soul.web.forwarde.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 “A” and implements org.dromara.soul.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 a() {
         return new A
   }
