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   }
