简单的 DOM file_get_html 不返回任何内容 [英] Simple DOM file_get_html returns nothing

问题描述

我正在尝试从某些网站抓取数据.对于几个站点，它似乎一切正常，但对于一个站点，它似乎无法获得任何 HTML.这是我的代码:

I'm trying to scrape data from some websites. For several sites it all seems to go fine, but for one website it doesn't seem to be able to get any HTML. This is my code:

<?php include_once('simple_html_dom.php');

$html = file_get_html('https://www.magiccardmarket.eu/?mainPage=showSearchResult&searchFor=' . $_POST['data']);

echo $html; ?>

我正在使用 ajax 来获取数据.当我在我的 js 中记录返回的值时，它完全是空的.

I'm using ajax to fetch the data. When I log the returned value in my js it's completely empty.

会不会是因为这个网站是在https上运行的?如果是这样，有没有办法解决它?(我尝试将 url 更改为 http，但结果相同)

Could it be due to the fact that this website is running on https? And if so, is there any way to work around it? (I've tried changed the url to http, but I get the same result)

更新:

如果我 var_dump $html 变量，我得到 bool(false).

If I var_dump the $html variable, I get bool(false).

我的 PHP 错误日志是这样写的:

My PHP error log says this:

推荐答案

这是你的用户代理，file_get_contents 默认不发送，所以:

It's your user agent, file_get_contents doesn't send one by default, so:

$url = 'http://www.magiccardmarket.eu/?mainPage=showSearchResult&searchFor=tarmogoyf';
$context = stream_context_create(array('http' => array('header' => 'User-Agent: Mozilla compatible')));
$response = file_get_contents($url, false, $context);
$html = str_get_html($response);
echo $html;
