Exclude middleware from some routes after definition

[metinogurlu]

I want to use grouping function after all the middelwares and routes registered. I have tried this solution but it is not suitable for me. I am using oapi generator and oapi already auto generate all the route definations in same place and with only one router. I just want to exclude or remove some middlewares from some endpoints after defined everything.

func (s *Service) registerMiddlewares() *Service {

    s.gin.Use(middlewares.RequestValidatorMiddleware(s.swagger))
    s.gin.Use(apmgin.Middleware(s.gin))
    s.gin.Use(middlewares.CorsMiddleware())
    s.gin.Use(gin.Logger())
    s.gin.Use(middlewares.RequestResponseLoggerMiddleware())

        // I want to exclude from /healthcheck and/or other endpoinds
    s.gin.Use(middlewares.Auth())

    s.gin = server.RegisterHandlers(s.gin, s.api)

    return s
}

This is auto generated code and calls by RegisterHandlers

func RegisterHandlersWithOptions(router *gin.Engine, si ServerInterface, options GinServerOptions) *gin.Engine {
    wrapper := ServerInterfaceWrapper{
        Handler:            si,
        HandlerMiddlewares: options.Middlewares,
    }

        // all the definitions here and runs after registering all the middlewares

    router.GET(options.BaseURL+"/api/v1/data/private", wrapper.GetPrivateData)

    router.GET(options.BaseURL+"/healthcheck", wrapper.GetHealthcheck)

    return router
}

Actual result is all the middlewares works for all endpoints. There is no way to use grouping function.

Do you try like this :

    func (s *Service) registerMiddlewares() *Service {

    s.gin.Use(middlewares.RequestResponseLoggerMiddleware())

        // I want to exclude from /healthcheck and/or other endpoinds
       group1 := s.gin.Group("/healthcheck",middlewares.Auth())
       {
          group1.GET("",func(c *gin.Context) {})
       }

    s.gin = server.RegisterHandlers(s.gin, s.api)

    return s
      }

@suttapak Thank you for your reply. But I think this is not suitable for me. Your example is a normal usage of grouping but in my scenario routes already defining in another place and if I specify some route definition before that (like yours) I am getting "handlers are already registered for path '/healthcheck'" error.

What is the best way to ignore the authentication middleware from some of the routes. Please tell me what todo? thank you

app := gin.Default()
app.Use(middleware.jwt)

/* ---------------------------  Public routes  --------------------------- */
app.POST("/users",userHandler)

 /* ---------------------------  Private routes  --------------------------- */
app.POST("/login",loginHandler)

app.Run()
