我需要将一些动态数据从控制器添加到app.blade.php，但是我找不到任何控制器。我应该在哪里做？谢谢
您需要从任何控制器加载视图，例如。 HomeController。在那里可以加载视图文件，例如home.blade.php。通常扩展app.blade.php。
因此您可以将数据从HomeController传递到视图。
class HomeController extends Controller
{
/**
* Show the application dashboard.
*
* @return \Illuminate\Contracts\Support\Renderable
*/
public function index()
{
return view('home', ['foo' => 'bar'] );
}
}
home.blade.php
@extends('layouts.app')
@section('content')
<div class="container">
<div class="row justify-content-center">
<div class="col-md-8">
<div class="card">
<div class="card-header">Dashboard</div>
<div class="card-body">
@if (session('status'))
<div class="alert alert-success" role="alert">
{{ session('status') }}
</div>
@endif
You are logged in!
</div>
