1. Introduce style file asset() method

We usually use Laravel, if we want to introduce Bootstrap Waiting for styles, sometimes the address we introduce is correct, but the effect of the style cannot be displayed. At this time, we can use the asset() method to introduce the style address. The usage is very simple, src="{{asset('The file that needs to be imported ')}}", when we use this method to introduce styles, there will be no errors, for example:

<link type="text/css" rel="styleSheet"  href="{{asset(&#39;css/bootstrap.min.css&#39;)}}" />
<link rel="stylesheet" type="text/css" href="{{asset(&#39;css/app.css&#39;)}}">
<script src="{{asset(&#39;js/jquery-3.5.0.min.js&#39;)}}"></script>
<script src="{{asset(&#39;js/bootstrap.min.js&#39;)}}"></script>

$url = asset('img/photo.jpg');

laravel comes with laravel-mix for Package static resources such as js, css, pictures, etc. The name of the generated file will be: app.asjduiik2l1323879dasfydua23.js, that is, the original js file name hash .js suffix, because the hash in the middle can change at any time, so when the js file is introduced on the page, the path to the file cannot be written. , instead use mix('app.js'). At this time, laravel will automatically match which app hash .js file the current app.js corresponds to (there will be a mix-manifest.json in the public directory of the project, which is saved The corresponding relationship between the two is determined, and the file will be updated every time the static resources are packaged).

Sometimes we don’t want the hash value to be added to the name of the static resource (in most cases, it is a third-party library of non-nodejs modules that is introduced independently). At this time, we can use the asset method directly, which Just simply and crudely find the file you named it.
