Laravel 使验证请求不起作用

Question

当我提交表单时，什么也没有发生。
这是我的步骤。

php artisan make:request PostRequest

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class PostRequest extends FormRequest
{
    public function authorize()
    {
        return true;
    }

    public function rules()
    {
        return [
            'title'=>['required','max:255'],
            'article'=>['required'],
            'image'=>['image']
        ];
    }

    public function messages()
    {
        return [
            'title.required'=>['need title'],
            'article.required'=>['need article'],
        ];
        
    }
}
?>

App/Http/Controllers/PostController.php

<?php

namespace App\Http\Controllers;


use App\Post;
use App\User;
use Illuminate\Http\Request;
use App\Http\Requests\PostRequest;
use Illuminate\Support\Facades\Auth;

class PostController extends Controller
{
    public function store(PostRequest $request)
    {
        Post::create($request->all());
        return redirect()->route('post.index');
    }
}
?>

如果我不使用 PostRequest 它可以完美地工作，就像这样。

app/Http/Controllers/PostController.php

public function store(Request $request)
    {
        $post=new Post;
        $post->user_id=Auth::user()->id;
        $post->title=$request->title;
        $post->article=$request->article;
        $post->image=$request->image;
        $post->save();
        return redirect()->route('post.index');
    }

我错过了什么步骤？ 谢谢大家。

您的 rules() 函数有一个返回数组。

public function rules()
{
    return [
        'title'=>['required','max:255'],
        'article'=>['required'],
        'image'=>['image']
    ];
}

改成

public function rules()
{
    return [
        'title'=>'required|max:255',
        'article'=>'required',
        'image'=>'image'
    ];
}
