Isu sambungan MySQL Laravel Sail Docker
<p>Saya cuba mengakses pangkalan data melalui aplikasi Laravel yang digunakan dalam bekas Docker, tetapi saya mendapat mesej ralat berikut: </p>
<pre class="brush:php;toolbar:false;">SQLSTATE[HY000] [2002] Sambungan ditolak
PILIH * DARI `posts`</pre>
<p>Terdapat jadual yang dipanggil siaran dalam pangkalan data yang saya cuba akses daripada localhost/siaran.</p>
<p>/posts的Blade模板如下:</p>
<pre class="brush:php;toolbar:false;">@extends('app')
@section('kandungan')
<h1>Halaman indeks catatan</h1>
@forelse ($posts sebagai $post)
<h2>{{ $post->tajuk }}</h2>
@kosong
<h2>Tiada siaran!</h2>
@endforelse
@endsection</pre>
<p>负责/posts的web.php中的路由如下:</p>
<pre class="brush:php;toolbar:false;">Route::resource('/posts', PostController::class)->only(['index', 'store']);< /pra>
<p>PostController的index函数如下:</p>
<pre class="brush:php;toolbar:false;">indeks fungsi awam()
{
$posts = Post::semua();
return view('posts.index', compact('posts'));
}</pre>

<p>我的操作系统是Windows 11,我在上面运行MySQL Workbench。这就是为什么我暴露3307端卫口而。 ;/p>
<p>使用当前设置,我可以在wsl终端中无问题地运行php artisan migrate。</p>
<p>为了避免连接被拒绝错误,我可以做什么来从localhost/posts访问posts?</p>
<p><strong>解决方案</strong>
通过将.env中的DB_HOST更改为mysql,同时将DB_PORT更改为3306来解决问题。</p>
<p><strong>编辑后的.env文件</strong></p>
