在缓存中包装 laravel 查询::remember

【中文标题】在缓存中包装 laravel 查询::remember【英文标题】：Wrap laravel query inside cache::remember 【发布时间】：2022-01-14 20:31:36 【问题描述】：我想将我的 laravel 查询包装在 cache::remember() 方法中，这不是什么大问题。我的问题是我的查询首先从控制器调用该函数，并且该文件中有一个文件 transaction.php。我正在调用这个函数，在它之后，我在这个函数返回查询的最后放置了一些 where() 条件。最终查询给出结果，我将其传递到 Yajra 数据表中。 简而言之，我的查询不在同一个文件上，因此我可以包装在 cache::remember() 函数中。
我如何包装我的查询，它放在两个文件中，controller 和 transaction.php。希望你能理解。
这是控制器内部的一个函数：

你可以看到附加的图片我的目标是如何在这个查询上使用 cache::remember。
Controller file
transactions.php file
【问题讨论】：
您应该在问题本身中分享相关代码，而不是图片。当人们必须在各个页面中跳转时，很难理解。我个人不太希望 imgur 收集我的任何个人信息，以便我了解您的问题。 我已经添加了代码。 代码太多了。尝试创建minimal reproducible example 并更简要地解释您的问题。 好的，先生，让我来做吧。 【参考方案1】：扩展 transactionUtil 文件以执行整个查询。您还需要收集用于构造查询的所有部分，以形成它们的唯一组合的唯一键。例如，这可能是事务实用程序中的一个函数：
function getFullResult($business_id, $sale_type)
$queryParameters = array_merge(compact('business_id, sale_type'), request()->all()); // You can filter these into the ones that are used for the query only
$cacheDurationSeconds = 3600;
return Cache::remember('getFullResult'.md5(json_encode($queryParameters)), $cacheDurationSeconds, function () use ($business_id, $sale_type)
$sells = $this->getListSells($business_id, $sale_type, request()->customer_id);
if (request()->only_subscriptions)
$sells->where(function ($q)
$q->whereNotNull('transactions.recur_parent_id')
->orWhere('transactions.is_recurring', 1);
);
if (!empty(request()->list_for) && request()->list_for == 'service_staff_report')
$sells->whereNotNull('transactions.res_waiter_id');
// ....
return $sells->where('transactions.is_suspend', 1)
->with($with)
->addSelect('transactions.is_suspend', 'transactions.res_table_id', 'transactions.res_waiter_id', 'transactions.additional_notes')
->get();
);
这里我使用md5 生成唯一密钥，因为它速度快，并且对于这个特定用例而言，哈希冲突的可能性很低。
但是，鉴于查询的复杂性，您需要质疑在请求中获得多个相同参数的可能性，因为如果您不这样做，那么缓存将无济于事。
【讨论】：
所以你的意思是我需要将我所有剩余的代码，包括 getListSell() 包含在缓存中？ 构建和执行查询所需的所有代码都必须放在remember 回调中，因此只有在之前没有缓存过该确切查询的情况下才会执行
哇，非常感谢你每件事都很清楚，我很困惑。以上是关于在缓存中包装 laravel 查询::remember的主要内容，如果未能解决你的问题，请参考以下文章
Laravel 7：禁用登录和自动登录（remember_token）
没有 remember_token 的 Laravel 5 身份验证
在 Laravel 4 中实现 Remember Me 函数会返回错误
