import (
  "log"
  "time"

  "github.com/gin-gonic/gin"
)

type Person struct {
  Name     string    `form:"name"`
  Address  string    `form:"address"`
  Birthday time.Time `form:"birthday" time_format:"2006-01-02" time_utc:"1"`
}

func main() {
  route := gin.Default()
  route.GET("/testing", startPage)
  route.Run(":8085")
}

func startPage(c *gin.Context) {
  var person Person
  // Si se usa `GET`, únicamente  es empleado el `Form` binding engine (`query`).
  // Si se emplea `POST`, se revisa primero el `content-type` para `JSON` o `XML`, para así usar entonces `Form` (`form-data`).
  // Véase más en https://github.com/gin-gonic/gin/blob/master/binding/binding.go#L48
  if c.ShouldBind(&person) == nil {
    log.Println(person.Name)
    log.Println(person.Address)
    log.Println(person.Birthday)
  }

  c.String(200, "Success")
}
