我通过PHP curl_exec请求URL时收到302错误消息,但手动执行时得到了代码200。可能导致结果不同的差异是什么?
假设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,或者重定向了所请求的URL。但是,当我手动将URL放置到浏览器中时,它没有进行重定向,而是将我带到正确的位置。
我想念什么吗?这两个请求的结果如何不同?
提前感谢

您好,我在CURLOPT_FOLLOWLOCATION选项设置为true的情况下重新运行了脚本,并且得到了以下输出:

我不确定它在说什么,但是我想它已被重定向到http://somehost.com/circle,然后重定向到http://somehost.com/circle。这是正确的吗?
可能是脚本将重定向用于支票cookie或可能用于其他功能。
您可以在$s
输出中看到重定向URL。只需在脚本末尾插入echo $s;
。
您还可以设置CURLOPT_FOLLOWLOCATION,然后在自动模式下通过重定向将使卷曲卷曲。
尝试添加更多选项
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
