Laravel 啟航 Docker MySQL 未連接

Question

我正在嘗試通過 laravel 應用程序訪問數據庫，該應用程序正在通過 docker 容器部署，但由於某種原因，我收到以下消息：

SQLSTATE[HY000] [2002] Connection refused
SELECT * FROM `posts`

數據庫有一個名為 posts 的表，我正在嘗試從 localhost/posts 訪問。

/posts 的刀片模板如下：

@extends('app')
@section('content')
    <h1>Posts index page</h1>
    @forelse ($posts as $post)
        <h2>{{ $post->title }}</h2>
    @empty
        <h2>No posts!</h2>
    @endforelse
@endsection

web.php 負責 /posts 的 Route 是這個：

Route::resource('/posts', PostController::class)->only(['index', 'store']);

PostController 的索引 function 是這個：

public function index()
    {
        $posts = Post::all();
        return view('posts.index', compact('posts'));
    }

我的 env 文件如下所示：

我的操作系統是 Windows 11，我在上面運行 MySQL Workbench。 這就是為什么我公開 3307 端口而不是 3306 的原因。

使用當前設置，我可以從 wsl 終端毫無問題地運行 php artisan migrate。

我該怎么做才能從 localhost/posts 訪問帖子而不會出現 Connection refused 錯誤？

在 .env 文件中使用mysql作為 DB_HOST 值
