@todo Error processing need to be improved.
You can also throw an exception in your controller as follows:
func (this *MainController) Get() {
this.Abort("401")
v := this.GetSession("asta")
if v == nil {
this.SetSession("asta", int(1))
this.Data["Email"] = 0
} else {
this.SetSession("asta", v.(int)+1)
this.Data["Email"] = v.(int)
}
this.TplNames = "index.tpl"
}
Then Beego will not execute rest code of the function body when you call `this.Abort("401")`, and gives following default page view to users:

Beego supports following error code: 404, 401, 403, 500 and 503, you can customize your error handle, for example, use following code to replace 404 error handle process:
func page_not_found(rw http.ResponseWriter, r *http.Request){
t,_:= template.New("beegoerrortemp").ParseFiles(beego.ViewsPath+"/404.html")
data :=make(map[string]interface{})
data["content"] = "page not found"
t.Execute(rw, data)
}
func main() {
beego.Errorhandler("404",page_not_found)
beego.Router("/", &controllers.MainController{})
beego.Run()
}
You may be able to use your own `404.html` for your 404 error.
Beego also gives you ability to modify error message that shows on the error page, the following example shows how to set more meaningful error message when database has problems:
func dbError(rw http.ResponseWriter, r *http.Request){
t,_:= template.New("beegoerrortemp").ParseFiles(beego.ViewsPath+"/dberror.html")
data :=make(map[string]interface{})
data["content"] = "database is now down"
t.Execute(rw, data)
}
func main() {
beego.Errorhandler("dbError",dbError)
beego.Router("/", &controllers.MainController{})
beego.Run()
}
After you registered this customized error, you can use `this.Abort("dbError")` for any database error in your applications.
