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();
   }
