Question

我的PostCOntroller

 class PostController extends Controller
{
public function index()
{
    $posts = post::all();
    return view('posts.index',['p'=>$posts]);
}

public function show(post $post)
{
    return view('posts.show', ['x'=>$post]);
}

master.blade.php

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <meta http-equiv="X-UA-Compatible" content="ie=edge">

   <title>Document</title>
</head>
<body>
   <div class="container">
    <center><h1>POST<h1></center>
    @yield('body')

</div>

index.blade.php

@extends('posts.master')

@section('body')
  @foreach($p as $post)
  <div class="card mt-2">
  <a href = "{{ route('hello.show'),$post->id}}">{{$post->title}}</a>
  </div>
 @endforeach
@endsection

show.blade.php

@extends('posts.master')

@section('body')

<div class="card">
  <div class="card-body">
     <h3>{{$x->title}}</h3>
  </div>

  <div class="card-body">
     <h3>{{$x->content}}</h3>
  </div>

</div>

@endsection

web.php

Route::resource('hello','PostController');

php artisan route：list

 GET|HEAD  | hello              | hello.index   | App\Http\Controllers\PostController@index   | web          |
 POST      | hello              | hello.store App\Http\Controllers\PostController@store   | web          |
 GET|HEAD  | hello/create       | hello.create  | App\Http\Controllers\PostController@create  | web          |
 GET|HEAD  | hello/{hello}      | hello.show    | App\Http\Controllers\PostController@show    | web

在许多情况下，我已经将以上内容视为解决方案。如果我转到链接-127.0.0.1:8000/hello/2，那么它将向我显示数据..这意味着hello.show页面还可以...索引页面显示错误吗？我在做什么错了？

我尝试过

 <a href = "{{"route('hello.show'), [$post->id]"}}
 <a href = "{{"route('hello.show'), ['id'=>$post->id]"}}
 <a href = "{{"route('hello.show'), auth()->post->id]"}}

没有任何作用

错误

  public static function forMissingParameters($route)
{
    return new static("Missing required parameters for [Route: {$route- 
    >getName()}] [URI: {$route->uri()}].");
}

Missing required parameters for [Route: hello.show] [URI: hello/{hello}].

将参数放入路线函数

   <a href = "{{ route('hello.show',$post->id)}}">{{$post->title}}</a>

缺少路线5.6的必需参数
