Custom Sign Algorithm

Description

• Users can customize the signature authentication algorithm to achieve verification.

Extension

• The default implementation is org.apache.shenyu.plugin.sign.service.DefaultSignService.
• Declare a new class named CustomSignService and implements org.apache.shenyu.plugin.api.SignService.

 public interface SignService {      /**      * Sign verify pair.      *      * @param exchange   the exchange      * @return the pair      */     Pair<Boolean, String> signVerify(ServerWebExchange exchange); }

• When returning true in Pair, the sign verification passes. If there's false, the String in Pair will be return to the frontend to show.
• Register defined class as a Spring Bean.

   @Bean   public SignService customSignService() {         return new CustomSignService();   }
