GOLANG > How to bind ajax json data to custom struct type?
Why do not binding ajax json data for my custom struct type?
My env:
- golang
- echo framework
go binding function
/**
* function : Model Init
*/
func modelInit(c echo.Context) tetrisModel.Tetris {
tetris := tetrisModel.DefaultInit()
if err := c.Bind(tetris); err != nil {
c.Logger().Error(err)
}
return *tetris
}
call modelInit
func Control(c echo.Context) tetrisModel.Tetris {
tetris := modelInit(c)
fmt.Println("=======================")
fmt.Println(c.FormValue("nowBlockPositionX"))
fmt.Println(tetris.NowBlockPositionX) // do not printing, why?
fmt.Println("=======================")
// ... ... other code... ...
}
the result:
fmt.Println(c.FormValue("nowBlockPositionX")) > working
fmt.Println(tetris.NowBlockPositionX) not working / not printing, why? (do not binding)
I hope, this code will print the '3'
DefaultInit()
func DefaultInit() *Tetris {
tetris := new(Tetris)
// some default data setting...
return tetris
}
tetris model code
type Tetris struct {
NowBlockPositionX int `form:"nowBlockPositionX" json:"nowBlockPositionX"`
NowBlockPositionY int `form:"nowBlockPositionY" json:"nowBlockPositionY"`
NowBlock map[string]int `form:"nowBlock" json:"nowBlock"`
// other data exists...
}
ajax json data(POST type)
{
nowBlockPositionX: 3
, nowBlockPositionY: 0
, nowBlock: {L: 0}
// other data exists...
}
I understand if go struct type has literal string (like this : form:"nowBlock" json:"nowBlock") then the structure auto bind('Bind function'). isn't it?
