# Controllers from scratch
|
|
|
|
This example folder shows how I started to develop
|
|
the Controller idea inside the Iris web framework itself.
|
|
|
|
Now it's built'n feature and can be used as:
|
|
|
|
```go
|
|
// +build go1.9
|
|
|
|
// file main.go
|
|
package main
|
|
|
|
import (
|
|
"github.com/kataras/iris/_examples/routing/mvc/persistence"
|
|
|
|
"github.com/kataras/iris"
|
|
)
|
|
|
|
func main() {
|
|
app := iris.New()
|
|
app.RegisterView(iris.HTML("./views", ".html"))
|
|
|
|
db := persistence.OpenDatabase("a fake db")
|
|
|
|
app.Controller("/user/{userid:int}", NewUserController(db))
|
|
|
|
// http://localhost:8080/
|
|
// http://localhost:8080/user/42
|
|
app.Run(iris.Addr(":8080"))
|
|
}
|
|
```
|
|
|
|
```go
|
|
// +build go1.9
|
|
|
|
// file user_controller.go
|
|
package main
|
|
|
|
import (
|
|
"time"
|
|
|
|
"github.com/kataras/iris/_examples/routing/mvc/persistence"
|
|
|
|
"github.com/kataras/iris"
|
|
)
|
|
|
|
// User is our user example controller.
|
|
type UserController struct {
|
|
iris.Controller
|
|
|
|
// All fields that are tagged with iris:"persistence"`
|
|
// are being persistence and kept between the different requests,
|
|
// meaning that these data will not be reset-ed on each new request,
|
|
// they will be the same for all requests.
|
|
CreatedAt time.Time `iris:"persistence"`
|
|
Title string `iris:"persistence"`
|
|
DB *persistence.Database `iris:"persistence"`
|
|
}
|
|
|
|
func NewUserController(db *persistence.Database) *User {
|
|
return &UserController{
|
|
CreatedAt: time.Now(),
|
|
Title: "User page",
|
|
DB: db,
|
|
}
|
|
}
|
|
|
|
// Get serves using the User controller when HTTP Method is "GET".
|
|
func (c *UserController) Get() {
|
|
c.Tmpl = "user/index.html"
|
|
c.Data["title"] = c.Title
|
|
c.Data["username"] = "kataras " + c.Params.Get("userid")
|
|
c.Data["connstring"] = c.DB.Connstring
|
|
c.Data["uptime"] = time.Now().Sub(c.CreatedAt).Seconds()
|
|
}
|
|
|
|
/* Can use more than one, the factory will make sure
|
|
that the correct http methods are being registed for this
|
|
controller, uncommend these if you want:
|
|
|
|
func (c *User) Post() {}
|
|
func (c *User) Put() {}
|
|
func (c *User) Delete() {}
|
|
func (c *User) Connect() {}
|
|
func (c *User) Head() {}
|
|
func (c *User) Patch() {}
|
|
func (c *User) Options() {}
|
|
func (c *User) Trace() {}
|
|
*/
|
|
|
|
/*
|
|
func (c *User) All() {}
|
|
// OR
|
|
func (c *User) Any() {}
|
|
*/
|
|
```
