试图提取Goutte数据以查看

Question

我已经工作了几个小时，试图找出如何从拉拉维尔的观点中提取一些数据。

我的主计长如下：

  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'));
});


    }

然后我的看法是：

@extends('layouts.app')

@section('content')

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


@endsection

任何帮助都将不胜感激！

Answer 1

假设crawler返回一个集合，请尝试如下所示：

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]);
}
