前言

最近开始学习GO的WEB框架,IRIS号称是Go最快的后端Web框架,目前发展最快的Go Web框架。提供完整的MVC功能并且面向未来。
所以先从它开始。

github地址
https://github.com/kataras/iris
文档
https://docs.iris-go.com/

安装

go get -u github.com/kataras/iris

编辑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")) 
   }

运行

go run main.go

新打开个窗口执行
curl http://localhost:8080
结果 Hello world!
或在浏览器 访问http://localhost:8080

测试
现在对它进行简单压力测试
系统配置 1核 1G内存 , 操作系统:CentOS 7.4 64位

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