Question

代码：

$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, "https://detail.1688.com/offer/543783250479.html?sk=consign");
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$a = curl_exec($ch);
$data = curl_exec($ch);
curl_close($ch);
var_dump($data);

结果：

string(727) "HTTP/1.1 302 Moved Temporarily

注意到我将CURLPT_RETURNTRANSFER设置为true，它仍然给出了302结果。有人可以给我一些建议吗？

Answer 1

设置CURLOPT_FOLLOWLOCATION以使curl遵循重定向。您已将其设置为FALSE。用

纠正它

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

CURLOPT_RETURNTRANSFER是将转移作为curl_exec（）返回值的字符串返回，而不是直接输出。

为什么我的PHP中的cURL不遵循重定向，即使我将“CURLOPT_RETURNTRANSFER”设置为true？
