我想使用slug，但是当我单击并跳转到特定帖子时，404 找不到。

  

URL运行良好，所以我不知道为什么我看不到   结果。

web.php

Route::get('results/{post}','ResultsController@show')->name('posts.show');

post.php

public function getRouteKeyName()
{
    return 'slug';
}

ResultsController.php

public function show(Post $post)
{
    $recommended_posts = Post::latest()
                        ->whereDate('date','>',date('Y-m-d'))
                        ->where('category_id','=',$post->category_id)
                        ->where('id','!=',$post->id)
                        ->limit(7)
                        ->get();


    $posts['particular_post'] = $post;
    $posts['recommended_posts'] = $recommended_posts;

    return view('posts.show',compact('posts'));
}

表

Schema::create('posts',function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->string('image');
        $table->unsignedBigInteger('category_id');
        $table->string('title');
        $table->string('slug');
        $table->string('place');
        $table->string('map');
        $table->date('date');
        $table->string('organizer');
        $table->string('organizer_link');
        $table->timestamp('published_at')->nullable();
        $table->text('description');
        $table->timestamps();
    });

PostsController.php

 public function store(CreatePostsrequest $request)
{
    //upload the image to strage
    //dd($request->image->store('posts'));
    $image = $request->image->store('posts');

    //create the posts
    $post = Post::create([
        'image' => $image,'category_id' => $request->category,'title' => $request->title,'slug' => str_slug($request->title),'place' => $request->place,'map' => $request->map,'date' => $request->date,'organizer' => $request->organizer,'organizer_link' => $request->organizer_link,'published_at' => $request->published_at,'description' => $request->description
    ]);

result.blade.php

<a href="{{ route('posts.show',[$post->id,$post->slug]) }}" class="title-link">{{ str_limit($post->title,20) }}</a>
