使用phpcrawl与Laravel 5.4

Question

我试图在Laravel5.4中使用cuab的PHPCrawl，并通过composer使用这个软件包：https://packagist.org/packages/mmerian/phpcrawl将它包括进来。

我试过运行以下示例代码：

class MyCrawler extends PHPCrawler  
{ 
  function handleDocumentInfo($DocInfo)  
  { 
    if (PHP_SAPI == "cli"){
      $lb = "\n"; 
    } else {
      $lb = "<br />"; 
    }
    echo "Page requested: ".$DocInfo->url." (".$DocInfo->http_status_code.")".$lb; 
    echo "Referer-page: ".$DocInfo->referer_url.$lb; 

    if ($DocInfo->received == true) {
      echo "Content received: ".$DocInfo->bytes_received." bytes".$lb; 
    }
    else {
      echo "Content not received".$lb;  
    }

    echo $lb; 
    flush(); 
  }  
} 

$crawler = new MyCrawler(); 
$crawler->setURL("www.php.net"); 
$crawler->addContentTypeReceiveRule("#text/html#"); 
$crawler->addURLFilterRule("#\.(jpg|jpeg|gif|png)$# i"); 
$crawler->enableCookieHandling(true);  
$crawler->setTrafficLimit(1000 * 1024); 
$crawler->go(); 
$report = $crawler->getProcessReport(); 

if (PHP_SAPI == "cli") {
  $lb = "\n"; 
} else {
  $lb = "<br />"; 
}

echo "Summary:".$lb; 
echo "Links followed: ".$report->links_followed.$lb; 
echo "Documents received: ".$report->files_received.$lb; 
echo "Bytes received: ".$report->bytes_received." bytes".$lb; 
echo "Process runtime: ".$report->process_runtime." sec".$lb; 

但它会引发多个错误，如下所示：

找不到类‘App\Http\Controller\PHPCrawler’

如何引用正确的命名空间，以便我可以在Laravel中使用脚本？

Answer 1

您应该通过composer.json文件中的类映射添加这些文件。您可以在它们的github页面上看到类映射是什么样子的示例，在编写本报告时，这个示例如下所示：

"autoload": {
    "classmap": [
        "libs/Utils/PHPCrawlerUtils.class.php",
        "libs"
    ]
}

您必须在文件的前缀加上vendor/mmerian/phpcrawl或任何指向libs文件夹的路径。
