如何为本地托管的视频创建Blob网址？

Question

我已经在本地主机上托管了一个视频

class Type extends Model {
    use \Staudenmeir\EloquentHasManyDeep\HasRelationships;

    public function Apartment() {
        return $this->hasManyDeep(Apartment::class, [City::class, Street::class, House::class])
            ->where('apartments.type_id', $this->id);
    }
}

如何将其转换为blob url，以下是我的代码不起作用

 'localhost:3000/videos/a1.m4'
