main.go
package main

import(
    "net/http"
    "github.com/labstack/echo"
)

func main() {
    e := echo.New()
    e.GET("/",root)
    e.Start(":8080")
}
func root(c echo.Context) error {
    if e.Request().Host == "localhost:8080"{
        return c.JSON(http.StatusOK,e.Request().Host)   
    }else{
        return c.JSON(http.StatusBadRequest,e.Request().Host)
    }
}
requset.sh
$curl localhost:8080
