Use the AbortWithStatusJSON function in gin to achieve echo-like effects.

package main

import (
        "github.com/gin-gonic/gin"
)

func check() gin.HandlerFunc {
        return func(c *gin.Context) {
                if c.Request.URL.Path != "/test" {
                        c.AbortWithStatusJSON(500, gin.H{"message": "path fail"})
                }
        }
}

func main() {
        r := gin.Default()
        r.Use(check())

        r.GET("/test", func(c *gin.Context) {
                c.JSON(200, gin.H{"message": "path ok"})
        })

        r.Run()
}
// curl 127.0.0.1:8080/test/haha
// {"message":"path fail"}
// curl  127.0.0.1:8080/test
// {"message":"path ok"}
