go iris初探

首先安装go环境。

$ brew install go

安装iris

$ go get -u github.com/kataras/iris

创建一个go的工作路径

$ mkdir /Users/xxx/goworkdir/src/gowork
$ touch main.go

编辑main.go

package main

import (
    "github.com/kataras/iris"

    "github.com/kataras/iris/middleware/logger"
    "github.com/kataras/iris/middleware/recover"
)

func main() {
    app := iris.New()
    app.Logger().SetLevel("debug")
    // Optionally, add two built'n handlers
    // that can recover from any http-relative panics
    // and log the requests to the terminal.
    app.Use(recover.New())
    app.Use(logger.New())

    // Method:   GET
    // Resource: http://localhost:8080
    app.Handle("GET", "/", func(ctx iris.Context) {
        ctx.HTML("<h1>Welcome</h1>")
    })

    // 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!"})
    })

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

启动server

$ go run main.go

这样就完成了第一次对iris的试探。
