package main
import "github.com/kataras/iris/v12"
func main() {
    app := iris.Default()
    app.Get("/ping", func(c iris.Context) {
        c.JSON(iris.Map{"message":"pong"})
    })
    app.Run(iris.Addr(":8080"))
}

编译hello.go

$ go run hello.go
Now listening on: http://0.0.0.0:8080
Application started. Press CMD+C to shut down.

curl

$ curl -X GET "http://127.0.0.1:8080/ping"
{"message":"pong"}

Query 参数

package main
import "github.com/kataras/iris/v12"
func main() {
    app:= iris.Default()
    app.Get("/hello", func(c iris.Context) {
        firstName:= c.URLParamDefault("firstname", "guest")
        lastName := c.URLParam("lastname")
        c.Writef("Hello %s %s\n",firstName,lastName)
    })
    app.Run(iris.Addr(":8080"))
}

curl 请求

Hello Jane Doe

Form

package main
import "github.com/kataras/iris/v12"
func main() {
    app := iris.Default()
    app.Post("/form", func(ctx iris.Context) {
        id := ctx.URLParam("id")
        page := ctx.URLParamInt32Default("page", 0)
        name := ctx.FormValue("name")
        message := ctx.FormValue("message")
        ctx.JSON(iris.Map{"id":id,"page":page,"name":name,"message":message})
    })
    app.Run(iris.Addr(":8080"))
}

$ curl -X POST 'http://127.0.0.1:8080/form?id=123&page=1' -F 'name=tony' -F 'message=hello'
{"id":"123","message":"hello","name":"tony","page":1}

Group

package main
import "github.com/kataras/iris/v12"
func main() {
    app := iris.Default()
    v1 := app.Party("api/v1")
    {
        v1.Post("/login",groupHandle)
    }
    v2 := app.Party("api/v2")
    {
        v2.Post("/login",groupHandle)
    }
    app.Run(iris.Addr(":8080"))
}
func groupHandle(c iris.Context) {
    addr := c.RemoteAddr()
    uri := c.FullRequestURI()
    path := c.Path()
    method := c.Method()
    c.JSON(iris.Map{"addr":addr,"uri":uri,"path":path,"method":method})
}

curl模拟请求测试

curl -X POST 'http://127.0.0.1:8080/api/v1/login'
{"addr":"127.0.0.1","method":"POST","path":"/api/v1/login","uri":"
curl -X POST 'http://127.0.0.1:8080/api/v2/login'
{"addr":"127.0.0.1","method":"POST","path":"/api/v2/login","uri":"http://127.0.0.1:8080/api/v2/login"}

MVC

package main
import (
    "github.com/baxiang/go-note/iris/mvc/hello-world/controller"
    "github.com/kataras/iris/v12"
    "github.com/kataras/iris/v12/mvc"
)
func main() {
    app := iris.Default()
    mvc.New(app).Handle(&controller.HelloController{})
    // http://localhost:8080
    // http://localhost:8080/ping
    // http://localhost:8080/hello
    // http://localhost:8080/custom_path
    app.Run(iris.Addr(":8080"))
}

创建controller

package controller
import (
    "github.com/kataras/iris/v12"
    "github.com/kataras/iris/v12/mvc"
)
type HelloController struct {
}
// Get serves
// Method:   GET
// Resource: http://localhost:8080
func (c *HelloController) Get() mvc.Result {
    return mvc.Response{
        ContentType: "text/html",
        Text:        "<h1>Welcome</h1>",
    }
}
// GetPing serves
// Method:   GET
// Resource: http://localhost:8080/ping
func (c *HelloController) GetPing() string {
    return "pong"
}
// GetHello serves
// Method:   GET
// Resource: http://localhost:8080/hello
func (c *HelloController) GetHello() interface{} {
    return map[string]string{"message": "Hello Iris!"}
}
func (c *HelloController) BeforeActivation(b mvc.BeforeActivation) {
    anyMiddlewareHere := func(ctx iris.Context) {
        ctx.Application().Logger().Warnf("Inside /custom_path")
        ctx.Next()
    }
    b.Handle("GET", "/custom_path", "CustomHandlerWithoutFollowingTheNamingGuide", anyMiddlewareHere)
}
