获取Gin的Metadata信息

如果需要打印Gin实例路由注册信息「路径、方法」，如何简单获取？

定义路由

    MetadataV1Router := r.Group("/metadata/v1")

    middleware.MetadataV1Router(MetadataV1Router, r)

定义中间件

import (
    "fmt"
    "github.com/gin-gonic/gin"
    hrequest "gitlab-ecs.litatom.com/infra/hermes/request"
)

func MetadataV1Router(r *gin.RouterGroup, router *gin.Engine) gin.IRoutes {

    {
        r.GET("/apis", MetaAPIInfoMiddleware(router))
    }

    return r
}

type Route struct {
    Method  string
    Path    string
    Handler string
    HandlerFunc any
}

func MetaAPIInfoMiddleware(router *gin.Engine) gin.HandlerFunc {

    return func(c *gin.Context) {

        var (
            req = hrequest.HGin{C: c}
            routes []Route
        )

        for _, route := range router.Routes() {
            fmt.Printf("Method: %s, Path: %s, Handler: %s\n", route.Method, route.Path, route.Handler)
        }

        for _, route := range router.Routes() {
            routes = append(routes, Route{Method: route.Method, Path: route.Path,})
        }
        req.SuccessResponse(routes)

        c.Next()

    }
}

效果
