使用 curl_getinfo（）根据您的使用情况，您可以使用 CURLINFO_REDIRECT_URL 或 CURLINFO_EFFECTIVE_URL b
$ b

Use curl_getinfo() with CURLINFO_REDIRECT_URL or CURLINFO_EFFECTIVE_URL depending on your use case.

CURLINFO_REDIRECT_URL - 禁用 CURLOPT_FOLLOWLOCATION ：在最后一个事务中找到的重定向URL，应该手动请求下一个。启用 CURLOPT_FOLLOWLOCATION 选项：此为空。此情况下的重定向网址位于 CURLINFO_EFFECTIVE_URL

CURLINFO_REDIRECT_URL - With the CURLOPT_FOLLOWLOCATION option disabled: redirect URL found in the last transaction, that should be requested manually next. With the CURLOPT_FOLLOWLOCATION option enabled: this is empty. The redirect URL in this case is available in CURLINFO_EFFECTIVE_URL

$url = 'https://google.com/';

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);

$html = curl_exec($ch);

$redirectedUrl = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL);

curl_close($ch);

echo "Original URL:   " . $url . "\n";
echo "Redirected URL: " . $redirectedUrl . "\n";
