go之web框架 iris

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/
