GO语言用户修改加密密码

定义修改密码的结构体

type PasswordReset struct {
    CurrentPassword string `json:"currentPassword"`//当前密码
    Password        string `json:"password"`//新密码
}

• 密码加密算法 ：bcrypt

密码校验部分

//将用户自己密码和传入的旧密码转化成[]byte类型，然后进行对比
func PasswordVerify(encryptedPassword, password string) error {
    if err := bcrypt.CompareHashAndPassword([]byte(encryptedPassword), []byte(password)); err != nil {
        return fmt.Errorf("incorrect password")
    }
    return nil
}
//密码校验
func (u *globaluserOperator) PasswordVerify(username string, password string) error {
    obj, err := u.globalUserGetter.Get("", username)
    if err != nil {
        klog.Error(err)
        return err
    }
    user := obj.(*authv1alpha2.GlobalUser)
    err = PasswordVerify(user.Spec.EncryptedPassword, password)
    if err != nil {
        return fmt.Errorf("incorrect CurrentPassword")
    }
    return nil
}
//根据用户名获取用户
func (u *globaluserOperator) fetch(username string) (*authv1alpha2.GlobalUser, error) {
    obj, err := u.globalUserGetter.Get("", username)
    if err != nil {
        klog.Error(err)
        return nil, err
    }
    user := obj.(*authv1alpha2.GlobalUser).DeepCopy()
    return user, nil
}

修改密码

func (u *globaluserOperator) ModifyPassword(username string, password string)  (*authenticationv1alpha2.GlobalUser, error) {
    //根据用户名获取用户
    user, err := u.fetch(username)
    if err != nil {
        klog.Error(err)
        return nil, err
    }
    //将新密码进行加密
    newpassword, err := encrypt(password)
    //将查到的user里面的密码换成加密的新密码
    user.Spec.EncryptedPassword = newpassword
    globaluser, err := u.kubesspaas.AuthenticationV1alpha2().GlobalUsers().Update(context.Background(), user, metav1.UpdateOptions{})
    if err != nil {
        klog.Error(err)
        return nil, err
    }
    return globaluser, nil
}

Handler层

type PasswordReset struct {
    CurrentPassword string `json:"currentPassword"`
    Password        string `json:"password"`
}

func (a *authenticationHandler) ModifyPassword(request *restful.Request, response *restful.Response)  {
    username := request.PathParameter("globaluser")
    var passwordReset PasswordReset

    err := request.ReadEntity(&passwordReset)
    if err != nil {
        api.HandleBadRequest(request, response, err)
        return
    }
    //判断当前密码和新密码不能为空
    if  passwordReset.CurrentPassword != "" &&passwordReset.Password != ""{
        if err = a.authMode.GlobalUser().PasswordVerify(username, passwordReset.CurrentPassword); err !=nil {
            if err != nil {
                api.HandleError(request, response,  err)
                return
            }
        }
        result,err := a.authMode.GlobalUser().ModifyPassword(username, passwordReset.Password)
        if err != nil {
            api.HandleError(request, response,  err)
            return
        }
        response.WriteEntity(result)
    }else {
        err = errors.New("CurrentPassword or NewPassword is null")
        api.HandleError(request, response,  err)
        return
    }
}
