use QL\QueryList;

$client = new GuzzleHttp\Client();
$res = $client->request('GET', 'http://www.aeink.com');
$html = (string)$res->getBody();
$title = QueryList::html($html)->find('.excerpt')->map(function ($Row) {
    global $client;
    $href = $Row->find("header>h2>a")->attr("href");
    preg_match('/www.aeink.com\/(\d+)/', $href, $matches);
    $id = $matches[1];
    $title = $Row->find("header>h2>a")->text();
    $res = $client->request('GET', $href);
    $html = (string)$res->getBody();
    $date = str_replace("日期：", "", QueryList::html($html)->find(".article-meta>span:first")->text());
    $author = QueryList::html($html)->find(".article-meta span:eq(1)")->text();
    $article_content = QueryList::html($html)->find(".article-content");
    $down = $article_content->find("#down-tipid>strong a")->attr("href");
    $article_content->find('.paydown,.post-copyright')->remove();
    $content = $article_content->html();
    $details = preg_replace_callback('/<img.*?src="(.*?)".*?>/is', function ($text) {
        global $title;
        return "\n" . '![' . $title . '](' . $text[1] . ')' . "\n";
    }, $content);
    $details = preg_replace_callback('/<style>(.*?)<\/style>/is', function ($text) {
        return "";
    }, $details);
    $text = QueryList::html($details)->find("")->text();
    $res = $client->request('GET', $down);
    $html = (string)$res->getBody();
    $dw = QueryList::html($html)->find(".panel-body a")->map(function ($R) {
        return [
            'name' => $R->text(),
            'href' => $R->href
        ];
    })->all();
    return [
        'thumb' => $Row->find(".focus img")->attr('src'),
        'title' => $title,
        'href' => $href,
        'id' => $id,
        'date' => $date,
        'author' => $author,
        'text' => $text,
        'dw' => $dw
    ];
});
print_r($title->all());

說明

AE博客安裝有waf（防火牆）建議三個小時執行一次，可以使用Redis緩存。
