如何评估laravel中资源收集API的元部分？

Question

我要实现的目标：要访问并打印集合的元部分

我尝试过的事情：

$products = products::where('product_name', 'LIKE', '%' . $q . '%')
    ->where('product_status', 1)
    ->where('publish_status', 1)
    ->orderBy('id', 'DESC')
    ->paginate(8);
// dd($products);

$products->appends(array(
    'query' => Input::get('search_text')
));

return Searchmanager::collection($products)->additional([
    'meta' => [
        'min_mrp' => '100',
    ]
]);

这是我的资源部分：

public function toArray($request)
{
    return parent::toArray($request);
    //dd($this->meta) what i tried but not working
}

这是我的回复：

 {
    "data": [
        {
            "id": 37,
            "product_webid": "pmtrj0vwj4",
            "product_name": "Samsung Galaxy Note 9",
            "slug": "samsung-galaxy-note-9",
            "description": "demo",

        }
    ],
    "links": {
        "first": "https://mobileappdatabase.in/ecomv2/api/search?query=sam&page=1",
        "last": "https://mobileappdatabase.in/ecomv2/api/search?query=sam&page=1",
        "prev": null,
        "next": null
    },
    "meta": {
        "current_page": 1,
        "from": 1,
        "last_page": 1,
        "path": "https://mobileappdatabase.in/ecomv2/api/search",
        "per_page": 8,
        "to": 7,
        "total": 7,
        "min_mrp": "100"
    }
} 

我尝试了dd（$ request）; ，$ this-> meta，$ this-> meta ['mn_mrp']，$ this-> collection-> meta对我不起作用，请帮帮我。
