安裝

go get -u github.com/kataras/iris

編輯main.go

package main

   import "github.com/kataras/iris"

   func main() {
     app := iris.Default()

     // Method:   GET
     // Resource: http://localhost:8080/
     app.Handle("GET", "/", func(ctx iris.Context) {
       ctx.HTML("Hello world!")
     })

     // same as app.Handle("GET", "/ping", [...])
     // Method:   GET
     // Resource: http://localhost:8080/ping
     app.Get("/ping", func(ctx iris.Context) {
       ctx.WriteString("pong")
     })

     // Method:   GET
     // Resource: http://localhost:8080/hello
     app.Get("/hello", func(ctx iris.Context) {
       ctx.JSON(iris.Map{"message": "Hello iris web framework."})
     })

     // http://localhost:8080
     // http://localhost:8080/ping
     // http://localhost:8080/hello
     app.Run(iris.Addr(":8080"))
   }

運行

go run main.go

新打開個窗口執行 
curl http://localhost:8080 
結果 Hello world! 
或在瀏覽器 訪問http://localhost:8080

測試 
現在對它進行簡單壓力測試 
系統配置 1核 1G內存 ， 操作系統：CentOS 7.4 64位

ab -n 10000 -c 1000 http://localhost:8080/
