What is Gin?

Gin is a web framework written in Golang.

It features a Martini-like API, but with performance up to 40 times faster than Martini.

If you need performance and productivity, you will love Gin.

HelloWorld of Gin Framework

首先～要裝gin

$ go get -u github.com/gin-gonic/gin

並在script import

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

hello world example

gin.default()建立一個route

route定義了在”/” path下以HTTP GET method回覆context

http status = 200

http印出hello world

route.Run沒有指定port的話就是預設8080port

package main
import (
 "github.com/gin-gonic/gin"
)
func main() {
 route := gin.Default()
 route.GET("/", func(c *gin.Context) {
  c.String(200, "hello world")
 })
 //default port:8080
 route.Run()
}

使用curl

$ curl -X GET localhost:8080

Gin default會把所有request log print出來
