Question

我通过PHP curl_exec请求网址时收到302错误消息，但手动执行时获得了代码200。什么可能是使结果不同的差异？

假设我在服务器中有以下代码：

$url = "http://localhost/circle/my_request/susan?confirm_key=c429d674e36ffe1a4f87fd5a17a0200dcfff0884e8bb3801d2a7d559dcc8d8cd1416295160";
$ch = @curl_init($url);
@curl_setopt($ch, CURLOPT_HEADER, true);
@curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);
@curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (compatible; Circle)");
@curl_setopt($ch, CURLOPT_TIMEOUT,60);
$s = @curl_exec($ch);
$curl_info = @curl_getinfo($ch);
$http_code = $curl_info['http_code'];

在这种情况下，$ http_code == 302，或者重定向请求的URL。但是当我手动将URL放到浏览器中时，它没有进行重定向，并把我带到了正确的位置。

我错过了什么吗？为什么这2个请求的结果不同？

提前致谢

您好我在CURLOPT_FOLLOWLOCATION选项设置为true的情况下重新运行脚本，并得到以下输出：

我不确定它的内容，但我猜它被重定向到http://somehost.com/circle然后转到http://somehost.com/circle。这是对的吗？

Answer 1

可能是脚本使用重定向检查cookie或可能是其他功能。

您可以在$s输出中看到重定向网址。只需将echo $s;插入脚本的末尾即可。
您也可以设置CURLOPT_FOLLOWLOCATION，然后在自动模式下通过重定向来卷曲。

Answer 2

尝试添加更多选项

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); 
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
