The caching tool provided by Laravel is easy to use, and some basic uses, such as get,put,forget,forever, are introduced in the manual. I used it like this at first:

The copy code is as follows:

If (! $article = Cache::get ('article_1')) {

$article = Article::find (1)

Cache::forever ('article_1',$article)

}

This is the most basic usage, which automatically determines whether the cache exists, or if it does not exist, it is fetched from the database and written to the cache.

Later, it was found that the model also comes with remember and rememberForever methods, for example:

The copy code is as follows:

$article = Article::rememberForever ('article_1')-> where (' id','=',1)

This has its limitations that data cannot be fully cached in complex queries, such as when associated data is preloaded with with ().

Then I found that Cache can also customize macro methods like Response, so I made the following attempt:

The copy code is as follows:

/ / register cache access macros

Cache::macro ('want',function ($key,$minutes=0,$callback) {

If (! $data = Cache::get ($key)) {

$data = call_user_func ($callback)

If ($minutes = = 0) {

Cache::forever ($key,$data)

} else {

Cache::put ($key,$data,$minutes)

}

}

Return $data

});

This method can be placed in bootstrap/start.php or in App::before () in filter, as convenient as your own project, and see how to use it:

The copy code is as follows:

$id = Input::get ('id')

$article = Cache::want ('article_'.$id,0,function () use ($id) {

Return Article::with ('tags')-> findOrFail ($id, [' id','cid','title','content_html as content','created_at','updated_at'])

});
