mongodb.go에서 Get의 FindeOne 부분을 이용해서 본인계정정보 확인 단계 진행

func (r *MongoDB) Get(opts ...*options.FindOneOptions) (interface{}, base.StatefulError) {
	res := r.col.FindOne(r.ctx, r.doc, opts...)
	if err := res.Err(); err != nil {
		blog.Error(r.ctx, err.Error())
		return nil, errors.ErrDatabaseQuery
	}
	res.Decode(r.doc)

	return r.doc, nil
}

Authorization이 무엇인지 파악

func (r *V1API) Route(rg *base.RouteGroup) {
	rg.Use(r.Authorization)

	rg.Group("/session", &v1.SessionAPI{})
	rg.Group("/code", &v1.CodeAPI{})
	rg.Group("/algorithm", &v1.AlgorithmAPI{})
	rg.Group("/class", &v1.ClassAPI{})

	user := &v1.UserAPI{}
	rg.GET("/user/", user.GetUser)
	rg.GET("/user/search", user.SearchUser)
}

type AuthorizationReq struct {
	base.HeaderRequester `json:"-"`

	Authorization string `header:"authorization"`
}

type AuthorizationResp struct {
}

func (r *V1API) Authorization(ctx *base.Context, req AuthorizationReq) (err base.StatefulError) {
	blog.Debug(ctx, "authorization api")
	defer func() {
		if e := recover(); e != nil {
			blog.Error(ctx, e)
			err = errors.ErrIncorrectToken
		}
	}()
	var user interface{}
	if u, p, ok := ctx.Request.BasicAuth(); ok {
		user, err = r.validateBasic(ctx, u, p)
	} else {
		user, err = r.validateToken(ctx, req.Authorization)
	}

	ctx.SetField(base.ContextUser, user)

	return err
}

 

 

아래 validateToken 및 validateBasic 코드 분석

func (r *V1API) validateToken(ctx *base.Context, auth string) (interface{}, base.StatefulError) {
	err := (base.StatefulError)(nil)
	tk := security.New(ctx, "", map[string]interface{}{})
	t := token.Token{
		Token: auth,
	}

	db := mongodb.New(ctx, &t)
	if _, err = db.Get(); err != nil {
		blog.Error(ctx, err.Error())
		return "", errors.ErrIncorrectToken
	}

	_, claims, err := tk.Validate(auth)

	return claims[security.ClaimUser], err
}

func (r *V1API) validateBasic(ctx *base.Context, email, password string) (interface{}, base.StatefulError) {
	u := user.User{
		Email:    email,
		Password: password,
	}
	db := mongodb.New(ctx, &u)
	_, err := db.Get()
	if err != nil {
		blog.Error(ctx, err.Error())
		return nil, errors.ErrWrongPassword
	}

	return email, nil
}
