# What to choose as the receiver for the Controller methods
Inside our controller-style routing, we declare a Controller
and all the methods for handling HTTP
requests are defined on the Controller
.
Example:
import "github.com/beego/beego/v2/server/web"
type UserController struct {
web.Controller
}
func (u *UserController) HelloWorld() {
u.Ctx.WriteString("hello, world")
}

Note that the receiver we use here is the Pointer receiver. So can we not use a pointer receiver?
The answer is yes:
import "github.com/beego/beego/v2/server/web"
type UserController struct {
web.Controller
}
func (u UserController) HelloWorld() {
u.Ctx.WriteString("hello, world")
}

It is no different from writing with a pointer receiver, and Beego handles both correctly.
So the question is, which one should we use?
- Preferring the use of pointers, as this is in line with long-standing Beego practice
- If you use the
CtrlXXX
family methods for registration, consider using a non-pointer. Of course there is no functional difference, except that one is(*UserController).HelloWord
and the other isUserController.HelloWord
, the latter one looks more refreshing;
For Beego, it is possible to use any receiver, they do not differ in functionality. The rest is a matter of elegance and personal preference.
