问题:如何使用 Golang 在 MongoDB 中存储 UUID?

github.com/google/uuid

插入的用户如下所示:

{"_id":{"$binary":"0bHYoNWSTV+KqWSl54YWiQ==","$type":"0"},"name":"Isabella"}
d1b1d8a0-d592-4d5f-8aa9-64a5e7861689
type User struct {
    UserId uuid.UUID `json:"userId" bson:"_id"`
    Name   string    `json:"name" bson:"name"`
}

func (repo userRepo) User(uuidIn uuid.UUID) (model.User, error) {
    collection := repo.database.Collection(mongoCollectionUser)
    var user model.User
    err := collection.FindOne(context.Background(),
        bson.M{"_id": uuidIn},
    ).Decode(&user)
    // err: mongo: no documents in result
}
