英文:
Please tell me how to bind multi-array to struct
问题
type _getData struct {
Title string json:"title" form:"title"
Date string json:"date" form:"date"
Pages []struct {
Order int json:"order" form:"title"
Description string json:"description" form:"description"
} json:"pages" form:"pages"
}
func CreateDiary(c echo.Context) error {
var getData _getData
c.Bind(&getData)
fmt.Print(getData)
...
通过c.FormParams命令接收以下数据，请告诉我如何将其绑定到_getData结构体中的pages字段。
map[address:[미국 캘리포니아 산타클라라 카운티 쿠퍼티노 ] date:[2021-10-05] location:[37.32779072192643 -122.01981157064436] map_id:[0] pages[0][description]:[123123] pages[0][order]:[0] pages[1][description]:[123123] pages[1][order]:[1] tags[0][id]:[12] tags[0][tag_name]:[sdf] title:[123123]]
我想将pages的数据作为数组获取，但是我得到的是[]。
英文:
type _getData struct {
Title string `json:"title" form:"title"`
Date string `json:"date" form:"date"`
Pages []struct {
Order int `json:"order" form:"title"`
Description string `json:"description" form:"description"`
} `json:"pages" form:"pages"`
func CreateDiary(c echo.Context) error {
var getData _getData
c.Bind(&getData)
fmt.Print(getData)
...
Receive the following data through c.FormParams command, please tell me how to bind it to _getData struct,
map[address:[미국 캘리포니아 산타클라라 카운티 쿠퍼티노 ] date:[2021-10-05] location:[37.32779072192643 -122.01981157064436] map_id:[0] pages[0][description]:[123123] pages[0][order]:[0] pages[1][description]:[123123] pages[1][order]:[1] tags[0][id]:[12] tags[0][tag_name]:[sdf] title:[123123]]
I want to get the data of pages as an array, but I am getting []

你可以使用第三方库。
import "github.com/monoculum/formam/v3"
type MyFormData struct {
Pages []struct {
Order int `formam:"order"`
Description string `formam:"description"`
} `formam:"pages"`
Tags []struct {
TagName string `formam:"tag_name"`
Id string `formam:"id"`
} `formam:"tags"`
Title string `formam:"title"`
}
func HttpHandler(c echo.Context) error {
myFormData := MyFormData{}
form, err := c.FormParams()
if err != nil {
return err
}
dec := formam.NewDecoder(&formam.DecoderOptions{TagName: "formam"})
dec.Decode(form, &myFormData)
return c.JSON(200, myFormData)
}
英文:
You can use 3rd party lib.
import "github.com/monoculum/formam/v3"
type MyFormData struct {
Pages []struct {
Order int `formam:"order"`
Description string `formam:"description"`
} `formam:"pages"`
Tags []struct {
TagName string `formam:"tag_name"`
Id string `formam:"id"`
} `formam:"tags"`
Title string `formam:"title"`
}
func HttpHandler(c echo.Context) error {
myFormData := MyFormData{}
form, err := c.FormParams()
if err != nil {
return err
}
dec := formam.NewDecoder(&formam.DecoderOptions{TagName: "formam"})
dec.Decode(form, &myFormData)
return c.JSON(200, myFormData)
}
