You can put any data inside the session, including objects. Seeing as a Collectionis just an object, you can do the same.
您可以将任何数据放入会话中，包括对象。将 a 视为一个Collection对象，您也可以这样做。
For example:
例如：
$products = Product::all();
Session::put('products', $products);
dd(Session::get('products'));
Should echo out the collection.
应该回显集合。

You should convert it to a plain array, then convert them back to models:
您应该将其转换为普通数组，然后将它们转换回模型：
Storing in the session
存储在会话中
$products = Product::all()->map(function ($product) {
return $product->getAttributes();
})->all();
Session::put('products', $products);
Retrieving from the session
从会话中检索
$products = Product::hydrate(Session::get('products'));
You can see an example of this method here.
您可以在此处查看此方法的示例。
