debugbar github 地址：https://github.com/barryvdh/laravel-debugbar/tree/1.8 laravel 针对1.8版本

Require this package with composer:

composer require barryvdh/laravel-debugbar:~1.8

After updating composer, add the ServiceProvider to the providers array in app/config/app.php

Note for Laravel 5: If you use a catch-all/fallback route, make sure you load the Debugbar ServiceProvider before your own App ServiceProviders.

'Barryvdh\Debugbar\ServiceProvider',

If you want to use the facade to log messages, add this to your facades in app.php:

'Debugbar' => 'Barryvdh\Debugbar\Facade',

The profiler is enabled by default, if you have app.debug=true. You can override that in the config files. You can also set in your config if you want to include/exclude the vendor files also (FontAwesome, Highlight.js and jQuery). If you already use them in your site, set it to false. You can also only display the js of css vendors, by setting it to 'js' or 'css'. (Highlight.js requires both css + js, so set to true for syntax highlighting)

php artisan config:publish barryvdh/laravel-debugbar
