In this recipe, we will learn how we can create a controller in Beego.

How to do it…

type FirstController struct 
{
  beego.Controller
}
type Employee struct 
{
  Id int `json:"id"`
  FirstName string `json:"firstName"`
  LastName string `json:"lastName"`
}
type Employees []Employee
var employees []Employee
func init()

  employees = Employees
  {
    Employee{Id: 1, FirstName: "Foo", LastName: "Bar"},
    Employee{Id: 2, FirstName: "Baz", LastName: "Qux"},

func (this *FirstController) GetEmployees() 
{
  this.Ctx.ResponseWriter.WriteHeader(200)
  this.Data...
