Golang : Handle sub domain with Gin

Just a supplementary tutorial for the previous tutorial on how to deal with sub domain in Golang. In case you find it too troublesome like me to introduce NewServeMux just to handle sub domain, do check out Gin framework. Below is an example on how to handle sub domain with Gin framework in Golang.

This example is from previous tutorial on how to deal with query string with a minor modification.

 package main

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

 func main() {
  router := gin.Default()
  router.GET("/query", func(c *gin.Context) {
 first := c.Request.URL.Query().Get("first")
 c.String(http.StatusOK, "First is "+first+"\n")

 second := c.Request.URL.Query().Get("second")
 c.String(http.StatusOK, "Second is "+second+"\n")
  })

  router.Run("api.example.com:8080") // port 8080 is optional //<---- here!

 }
