Laravel Sail Docker MySQL not connecting

我试图通过一个正在通过docker容器部署的laravel应用程序访问数据库，但由于某种原因，我得到以下消息:

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

数据库有一个名为posts的表，我试图从localhost/posts访问。

/posts的模板如下:

@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中负责/posts的路由是这样的:

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

PostController的索引函数是这样的

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

我的。env文件看起来像这样:

我的操作系统是Windows 11，我在上面运行MySQL工作台。这就是为什么我暴露3307端口而不是3306。

使用当前的设置，我可以在wsl终端上运行php artisan migrate而不会出现问题。

我能做些什么，以便从localhost/posts访问帖子而不获得连接拒绝错误?

<解决方案/strong>通过更改。env中的DB_HOST=mysql以及DB_PORT为3306解决了这个问题。

DB_CONNECTION=mysql
DB_HOST=mysql
DB_PORT=3306
DB_DATABASE=laravel_essentials_app
DB_USERNAME=sail
DB_PASSWORD=password
