1. 路由注册
定义一个用户登录路由
v1.POST("user/login", api.UserLogin)
2. 接口编写
2.1 service层
定义用户登录的服务结构
//UserLoginService 管理用户登陆的服务 type UserLoginService struct { UserName string `form:"user_name" json:"user_name" binding:"required,min=5,max=15"` Password string `form:"password" json:"password" binding:"required,min=8,max=16"` }
编写用户登录的服务方法
func (service *UserLoginService) Login() serializer.Response { ... }
2.2 api层
定义用户登录的服务
var userLoginService service.UserLoginService
绑定数据
运行userLoginService对象的login方法
res := userLoginService.Login()
用户登录的接口函数返回
c.JSON(200, res)
用户登录接口的完整代码
func UserLogin(c *gin.Context) { var userLoginService service.UserLoginService if err := c.ShouldBind(&userLoginService); err == nil { res := userLoginService.Login() c.JSON(200, res) } else { c.JSON(400, ErrorResponse(err)) logging.Info(err) } }
2.3 service
查询用户是否存在
if err := model.DB.Where("user_name=?", service.UserName).First(&user).Error; err != nil { //如果查询不到，返回相应的错误 if gorm.IsRecordNotFoundError(err) { logging.Info(err) code = e.ErrorNotExistUser return serializer.Response{ Status: code, Msg: e.GetMsg(code), } } logging.Info(err) code = e.ErrorDatabase return serializer.Response{ Status: code, Msg: e.GetMsg(code), } }
在model/user下进行密码
//CheckPassword 校验密码 func (user *User) CheckPassword(password string) bool { err := bcrypt.CompareHashAndPassword([]byte(user.PasswordDigest), []byte(password)) return err == nil }
验证用户密码
if user.CheckPassword(service.Password) == false { code = e.ErrorNotCompare return serializer.Response{ Status: code, Msg: e.GetMsg(code), } }
给用户签发token
token, err := util.GenerateToken(service.UserName, service.Password, 0)
定义claims的结构体
type Claims struct { ID uint `json:"id"` Username string `json:"username"` Authority int `json:"authority"` jwt.StandardClaims }
生成token函数
我们传入用户的id，username和password以及authority权限加密成token，后续就可以进行身份的验证 func GenerateToken(id uint ,username, password string, authority int) (string, error) { nowTime := time.Now() expireTime := nowTime.Add(24 * time.Hour) claims := Claims{ Username: username, Password: password, Authority: authority, StandardClaims: jwt.StandardClaims{ ExpiresAt: expireTime.Unix(), Issuer: "cmall", }, } tokenClaims := jwt.NewWithClaims(jwt.SigningMethodHS256, claims) token, err := tokenClaims.SignedString(jwtSecret) return token, err }
用户登录服务的完整代码
func (service *UserLoginService) Login() serializer.Response { var user model.User code := e.SUCCESS if err := model.DB.Where("user_name=?", service.UserName).First(&user).Error; err != nil { //如果查询不到，返回相应的错误 if gorm.IsRecordNotFoundError(err) { logging.Info(err) code = e.ErrorNotExistUser return serializer.Response{ Status: code, Msg: e.GetMsg(code), } } logging.Info(err) code = e.ErrorDatabase return serializer.Response{ Status: code, Msg: e.GetMsg(code), } } if user.CheckPassword(service.Password) == false { code = e.ErrorNotCompare return serializer.Response{ Status: code, Msg: e.GetMsg(code), } } token, err := util.GenerateToken(user.ID, service.UserName, 0) if err != nil { logging.Info(err) code = e.ErrorAuthToken return serializer.Response{ Status: code, Msg: e.GetMsg(code), } } return serializer.Response{ Status: code, Data: serializer.TokenData{User: serializer.BuildUser(user), Token: token}, Msg: e.GetMsg(code), } }
