Gin custom time.Time type can not use ShoudBindQuery get a value ,error : invalid character '-' after top-level value

Description

const Layout     = "2006-01-02 15:04:05"     // datetime
// CTime china time/date
// format Layout
type CTime time.Time

func (t CTime) MarshalJSON() ([]byte, error) {
    return marshalJSON[CTime](t)
}

func (t *CTime) UnmarshalJSON(b []byte) error {
    s := strings.Trim(string(b), `"`)
    if s == "" {
        return nil
    }
    if len(s) <= 10 {
        s = fmt.Sprintf("%s 00:00:00", s)
    }
    ti, err := parse(Layout, s)
    if err != nil {
        return err
    }
    *t = CTime(ti)
    return nil
}
func parse(layout, value string) (t time.Time, err error) {
    t, err = time.ParseInLocation(layout, value, time.Local)
    if err != nil {
        value = fmt.Sprintf(`"%s"`, value)
        err = t.UnmarshalJSON([]byte(value))
        return
    }
    return
}

model

type TOccupyAsset struct {
    global.GVA_MODEL_V2
    T             time.CTime     `json:"t" form:"t" gorm:"column:t;" swaggertype:"string"`
}

query

func FindTOccupyAsset(c *gin.Context) {
    var tOccupyAsset TOccupyAsset
    err := c.ShouldBindQuery(&tOccupyAsset)
    if err != nil {
        response.FailWithMessage(err.Error(), c)
        return
    }
    // ....
}

Actual result

// http://127.0.0.1:8888/tOccupyAsset/findTOccupyAsset?t=2024-08-09 10:10:10

error message:　invalid character '-' after top-level value

this problem occur to the source code: bind query.go and the method func mapForm()

in this function about custom time type error handle

this is not ptr

maybe like gorm handle custom type?

Environment

• go version: v1.22.5
• gin version (or commit ref): v1.9.0

issue like 3919 get request shoudbuildquey has this problem

@JimChenWYU url not shoud add "", this error happened before func (t *CTime) UnmarshalJSON(b []byte) error {xxx}

问题类似3919 获取请求 shoudbuildquey有这个问题

该pr已安全解决上述问题 #3933
