尝试提取Goutte数据查看

Question

我已经工作了几个小时试图弄清楚如何将一些数据提取到我在 Laravel 中的视图中。

我的控制器如下：

  public function practice(Request $request) 
    {

        $client = new Client();
        $crawler = $client->request('GET', 'https://www.polkadotpassport.com/');

$crawler->filter('.post-header')->each(function($node){
   $title = $node->filter('h2 > a');
    return view('flights', compact('title'));
});


    }

然后我的观点是：

@extends('layouts.app')

@section('content')

@foreach($title as $titles)
<h1>{{$titles}}</h1>
@endforeach


@endsection

如有任何帮助，我们将不胜感激！

假设 crawler 正在返回一个集合，请尝试类似的操作：

public function practice(Request $request)
{
        $client = new Client();
        $crawler = $client->request(
                'GET',
                'https://www.polkadotpassport.com/
        ');

        $titles = $crawler->filter('.post-header')->map(function($node){
                return $node->filter('h2 > a');
        });

        return view('flights', ['titles' => $titles]);
}
