我有以下代碼。處理程序func (authHandler *AuthHandler) Login(c *gin.Context) { var user models.User c.Bind(&user) if &user == nil { c.BindJSON(&user) } userObject, err := authHandler.userRepo.FindBy( models.User{ Email: user.Email, }, ) if err != nil { c.JSON(401, gin.H{"_message": "User not found."}) return } passErr := bcrypt.CompareHashAndPassword([]byte(userObject.Password), []byte(user.Password)) if passErr != nil { c.JSON(401, gin.H{"_message": "Password incorrect."}) return } token, err := services.CreateToken(userObject) if err != nil { c.JSON(401, gin.H{"_message": "Password incorrect."}) return } c.JSON(200, gin.H{"token": token, "user": gin.H{ "id": &userObject.ID, "first_name": &userObject.FirstName, "last_name": &userObject.LastName, "email": &userObject.Email, "avatar": &userObject.Avatar, "location": &userObject.Location, "bg_img": &userObject.BgImg, }})}模型// user.gotype User struct { ID string `gorm:"primary_key:true"` FirstName string `form:"first_name" json:"first_name,omitempty"` LastName string `form:"last_name" json:"last_name,omitempty"` Password string `form:"password" json:"password" bindind:"required"` Email string `gorm:"type:varchar(110);unique_index" form:"email" json:"email,omitempty" binding:"required"` Location string `form:"location" json:"location,omitempty"` Avatar string `form:"avatar" json:"avatar,omitempty"` BgImg string `form:"bg_img" json:"bg_img,omitempty"` CreatedAt time.Time UpdatedAt time.Time DeletedAt time.Time}我試過以幾種不同的方式進(jìn)行查找，但沒有運(yùn)氣。我每次都收到 401 響應(yīng)，模型中的 fmt.Prinlnt(err) 顯示record not found錯誤。

所以事實(shí)證明我需要將該DeletedAt字段設(shè)置為空值。在幕后，GORM 會自動檢查一個DeletedAt值。即SELECT * FROM users WHERE email = 'someone@gmail.com' AND deleted_at IS NULL。但是，我的DeletedAt字段被自動設(shè)置為空白日期，從技術(shù)上講，這不是NULL.
我添加了一個結(jié)構(gòu)...
type NullTime struct {
time.Time
Valid bool
}
然后更新了我的模型...
type User struct {
ID string `gorm:"primary_key:true"`
FirstName string `form:"first_name" json:"first_name,omitempty"`
LastName string `form:"last_name" json:"last_name,omitempty"`
Password string `form:"password" json:"password" bindind:"required"`
Email string `gorm:"type:varchar(110);unique_index" form:"email" json:"email,omitempty" binding:"required"`
Location string `form:"location" json:"location,omitempty"`
Avatar string `form:"avatar" json:"avatar,omitempty"`
BgImg string `form:"bg_img" json:"bg_img,omitempty"`
CreatedAt time.Time
UpdatedAt time.Time
DeletedAt NullTime
}

'gorm' 中的約定是在您的結(jié)構(gòu)中包含基本模型。
// Base Model definition from gomodel.go
type Model struct {
ID uint `gorm:"primary_key"`
CreatedAt time.Time
UpdatedAt time.Time
DeletedAt *time.Time
}
// Your struct
type User struct {
gorm.Model
Name string
}
如您所見，'gorm' 需要一個指針來處理 NULL 值。
