cURL表现很奇怪 [英] cURL acting very strange

问题描述

我正在成功使用cURL从外部域导入一些数据，直到尝试使用此URI: http://www.airbnb.com/calendar/ical/760186.ics?s=29623a93eb0e693c77591a711f082f06 ，这是一个ics日历. 我可以在命令行上成功运行它(尝试一下): shell >> curl https://www.airbnb.com/calendar/ical/760660.ics?s=593cc556438a8f0919beb6107b6f508d ，所以这不是网络问题.

I'm importing some data from external domains successful with cURL, until I tried with this URI: http://www.airbnb.com/calendar/ical/760186.ics?s=29623a93eb0e693c77591a711f082f06, which is a ics calendar. I can successfully run it on a command line (try for your selves): shell>> curl https://www.airbnb.com/calendar/ical/760660.ics?s=593cc556438a8f0919beb6107b6f508d, so it's not a network issue.

但是我的php脚本(确实返回其他URI)不返回这个.或更妙的是它返回false.

but my php script (that do return other URI) DO NOT return this. or better it return false.

这是小php

function file_get_contents_curl($url) {
    $ch = curl_init();

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

    $data = curl_exec($ch);
    curl_close($ch);
    return $data;
}

$ical1= "http://www.airbnb.com/calendar/ical/760186.ics?s=29623a93eb0e693c77591a711f082f06";
echo file_get_contents_curl($ical1);

我确实认为这与我的apache或php配置有关，因为它在appfog上运行，并且在我的旧xampp安装上运行. 要恢复:所有URI都使用旧的xampp安装，现在只有示例中的URI失败了.

I do think this has something to do with my apache or php configuration, because it runs on appfog and it run with my old xampp instalation. To resume: all URI worked with old xampp instalation and now just the one from the example fails.

在我的phpinfo()上，我可以阅读:

on my phpinfo() i can read:

推荐答案

URL是有效的，仅将URL放入浏览器就可以毫无问题地下载.

The URL is valid and can be downloaded no problems just by putting the URL in to a browser, so that isn't your problem.

URL重定向到相同的URL，但在安全的服务器上，但是您已经设置了CURLOPT_FOLLOWLOCATION，所以这也不是问题.

The URL redirects to the same URL but on a secure server, but you have set CURLOPT_FOLLOWLOCATION so that isn't your problem either.

但是，安全网址会执行javascript重定向到英国站点，这是您的问题.您正在拉回错误的文件.

However, the secure URL carries out a javascript redirect to the UK site, and this is your problem. You're pulling back the wrong file.

尝试使用URL https://www.airbnb.co.uk/calendar/ical/760186.ics?s=29623a93eb0e693c77591a711f082f06进行尝试，并查看其运行方式.

Try it with the URL https://www.airbnb.co.uk/calendar/ical/760186.ics?s=29623a93eb0e693c77591a711f082f06 instead and see how it goes.
