Laravel视图内容显示两次带参数的路径
我正在使用Laravel 5.5，我有两个带有这样的参数的路径
Route::get( 'route/{parameter}', 'Controller@action' )->name( 'controller.action' );
我的控制器操作只是加载视图：
public function action( $slug ) {
return view( 'view', [
'post' => Post::whereSlug( $slug )->first()
] );
}
我的基础app.blade.php查看内容是：

我的观点内容是这样的：
@extends('layouts.app')
@section('title', $title)
@section('container-class', 'container')
@section('content')
@if($post)
<div class="cover" style="background-image:url('{{Storage::url($post->file)}}');"></div>
<article class="article__container">
<h1>{{$post->title}}</h1>
<div>{!!$post->text!!}</div>
</article>
@endif
@stop
问题是我的观看内容显示重复，在实际观看内容之上有一个404，如下所示：

答案 0 :(得分：0)
这可能是由于你帖子的slu ..如果你在slug中包含特殊字符，Laravel将无法自动解决此问题，因为它假定它是另一个URL。我假设你正在尝试查看一个像<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">
<div id="first">
<button><h3>Random <div class ="icon" /></h3></button>
</div>
<div id="second">
<button><h3>Random <div class ="icon" /></h3></button>
</div>
<div id="third">
<button><h3>Random <div class ="icon" /></h3></button>
</div>
<div id="fourth">
<button><h3>Random <div class ="icon" /></h3></button>
</div>
<div id="last">
<button><h3>Random <div class ="icon" /></h3></button>
</div>
</div>这样的帖子的帖子，如果在路线中包含where语句，这将有效。你必须做这样的事情：
my/first/post这样路由将包含一个正则表达式，它验证完整的字符串是否有效。
我不知道为什么它会显示帖子和404页面，看起来你只是在Route::get('route/{parameter}', 'Controller@action')
->name('controller.action')
->where('parameter', '([A-Za-z0-9\-\/]+)');
答案 1 :(得分：0)
我想出来了，我会留下一个答案供将来参考，问题不在于Laravel，这是一个javascript问题，我有这个代码在头上：
<script>
var ajax = new XMLHttpRequest();
ajax.open('GET', '/images/sprites.svg', true);
ajax.send();
ajax.onload = function (e) {
var div = document.createElement('div');
div.innerHTML = ajax.responseText;
document.body.insertBefore(div, document.body.childNodes[0]);
};
</script>
加载一个svg sprite并将其插入要使用的页面中，ajax url在带有参数的路径上返回404，所以在页面上方显示了404页面，我使用像这样的绝对URL修复它：
ajax.open('GET', '{{URL::to('/')}}/images/sprites.svg', true);
谢谢大家的帮助。
