Laravel5.5源码详解 – Laravel-debugbar 及使用elementUI - ajax的注意事项

关于laravel对中间件的处理，请参中间件考另文， Laravel5.5源码详解 – 中间件MiddleWare分析 这里只是快速把debugbar的事务处理流程记录一遍。

我在Illuminate\Pipeline\Pipeline的then函数中进行中间件捕获，发现有下面这些中间件，

array:6 [▼
  0 => "Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode"
  1 => "Illuminate\Foundation\Http\Middleware\ValidatePostSize"
  2 => "App\Http\Middleware\TrimStrings"
  3 => "Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull"
  4 => "App\Http\Middleware\TrustProxies"
  5 => "Barryvdh\Debugbar\Middleware\InjectDebugbar"
]
array:6 [▼
  0 => "App\Http\Middleware\EncryptCookies"
  1 => "Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse"
  2 => "Illuminate\Session\Middleware\StartSession"
  3 => "Illuminate\View\Middleware\ShareErrorsFromSession"
  4 => "App\Http\Middleware\VerifyCsrfToken"
  5 => "Illuminate\Routing\Middleware\SubstituteBindings"
]

其中就包括这个Barryvdh\Debugbar\Middleware\InjectDebugbar，它是在larave启动时，在vendor\composer\installed.json发现并引入，

laravel-debugbar的配置在Barryvdh\laravel-debugbar\config\debugbar，里面解释比较详尽，这里也不再重复。顺便说一下，这个类是在Barryvdh\Debugbar\ServiceProvider中注册的，
