我是laravel的新手。我的应用程序有一个前端和一个后端。我已经设置了路线，控制器和其他必要的东西。但是每当我点击前端的帖子标题时，它就会重定向到后端而没有显示任何内容。我不知道我的问题在哪里。
[它重定向到后端][2]

这是控制器
<?php
namespace App\Http\Controllers;
use App\Category;
use App\Post;
use App\Tag;
use App\User;
use Illuminate\Http\Request;
class BlogController extends Controller
{
//
protected $limit =5;
public function index(){
$posts = Post::with('author')
->latestFirst()
->published()
->filter(request('term'))
->simplePaginate($this->limit);
return view("blogs.index", compact('posts'));
}
public function category(Category $category){
$categoryName = $category->title;
$posts = $category->posts()
->with('author')
->latestFirst()
->published()
->simplePaginate($this->limit);
return view ("blogs.index",compact('posts','categoryName'));
}
public function show(Post $post)
{
$post->increment('view_count');
return view("blogs.show",compact('post'));
}
public function author(User $author)
{
$authorName = $author->name;
$posts = $author->posts()
->with('category')
->latestFirst()
->published()
->simplePaginate($this->limit);
return view("blogs.index", compact('posts', 'authorName'));
}
public function tag(Tag $tag)
{
$tagName = $tag->title;
$posts = $tag->posts()
->with('author', 'category')
->latestFirst()
->published()
->simplePaginate($this->limit);
return view("blogs.index", compact('posts', 'tagName'));
}
}

答案 0 :(得分：-1)
public function show(Post $post) <-- this need full object for getting result
{
$post->increment('view_count');
return view("blogs.show",compact('post'));
}
just try this
public function show($slug){
$post = Post::where('slug', $slug)->firstorfail();
$post->increment('view_count');
return view("blogs.show",compact('post'));
}
