如何使用 CURL PHP 从 Google Business 获取评论

Question

我正在尝试在 Google 商务中获取评价。目标是通过 label 进行访问curl，然后从pane.rating.moreReviewslabel中获取值jsaction。

我如何修复下面的代码以获得curl？

function curl($url) {
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
  curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/27.0.1453.94 Safari/537.36');
  $html = curl_exec($ch);
  curl_close($ch);
  return $html;
}

$html = curl("https://www.google.com/maps?cid=12909283986953620003");
$DOM = new DOMDocument();
$DOM->loadHTML($html);
$finder = new DomXPath($DOM);
$classname = 'pane.rating.moreReviews';
$nodes = $finder->query("//*[contains(@jsaction, '$classname')]");
foreach ($nodes as $node) {
  $check_reviews = $node->nodeValue;
  $ses_key = preg_replace('/[^0-9]+/', '', $check_reviews);
}

// result should be: 166
echo $ses_key;

如果我尝试 do var_dump($html);，我会得到：

string(348437) " "

这个数字在每次页面刷新时都会发生变化。

如何查找 CID - 如果您在 Google 地图上有营业的商家：

\n

\n
• 在 Google 地图中搜索企业名称
\n
• 确保它\xe2\x80\x99 是唯一显示的结果。
\n
• 将 URL 中的 http:// 替换为 view-source:
\n
• 单击 CTRL+F 并在源代码中搜索 \xe2\x80\x9cludocid\xe2\x80\x9d
\n
• CID 将是 \xe2\x80\x9cludocid\\u003d\xe2\x80\x9d 之后的数字，直到最后一个数字
