Laravel 查看带有参数的路线显示两次的内容

Question

我正在使用 Laravel 5.5，我有两个带有这样参数的获取路由

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()
    ] );
}

我的基地app.blade.php查看内容是：

            <div class="@yield('container-class')">

我的浏览内容是这样的：

@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

问题是我的视图内容显示重复，一个 404 在实际视图内容之上，如下所示：

Answer 1

这可能是因为您的帖子有问题。如果您在 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。我假设您正在尝试查看一个 post，它有一个像 my/first/post 这样的 slug，如果您在路由中包含一个 where 语句，这将起作用。你必须做这样的事情：

Route::get('route/{parameter}', 'Controller@action')
    ->name('controller.action')
    ->where('parameter', '([A-Za-z0-9\-\/]+)');

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同时显示 post 和 404 页面，看起来你只是在 layouts.app

中包含了默认的 404 页面

Answer 2

我弄明白了，我会留下一个答案以供将来参考，问题不在于 Laravel，而是一个 javascript 问题，我头上有这段代码：

    <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 svg sprite 并将其插入要使用的页面，ajax url 在带有参数的路由上返回 404，因此 404 页面显示在视图上方，我通过使用这样的绝对 url 来修复它：

ajax.open('GET', '{{URL::to('/')}}/images/sprites.svg', true);

谢谢大家的帮助。
