这个网站似乎期待一个名为 的 cookie AspxAutoDetectCookieSupport
,如果它没有找到它,它会将您重定向到某个 cookie 检测页面,它会陷入循环:

所以你需要设置这个cookie: AspxAutoDetectCookieSupport=1
:
curl_setopt($ch, CURLOPT_COOKIE, 'AspxAutoDetectCookieSupport=1');
这解决了第一个问题,另一个问题出现了,如果您没有为用户代理设置值,它将向您发送此页面:
<html xmlns:atom="http://www.w3.org/2005/Atom">
<head><meta http-equiv="Content-Type" content="text/xml; charset=iso-8859-1" /><
title>
Untitled Page
</title><link href="App_Themes/Default/Common.css" type="text/css" rel="styleshe
et" /><link href="App_Themes/Default/Container.css" type="text/css" rel="stylesh
eet" /><link href="App_Themes/Default/Content.css" type="text/css" rel="styleshe
et" /><link href="App_Themes/Default/Login.css" type="text/css" rel="stylesheet"
/></head>
<body>
<form name="form1" method="post" action="rssCurrentJobs.aspx?site=5E6F361D43
64703D044F72" id="form1">
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwUKMTc2MTg4
NDc4NmRk" />
<div>
</div>
</form>
</body>
</html>
所以添加一个用户代理值:
curl_setopt($ch, CURLOPT_USERAGENT, "SomeUserAgent");
完整代码:
function url_get_contents ($Url) {
if (!function_exists('curl_init')){
die('CURL is not installed!');
}
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $Url);
curl_setopt($ch, CURLOPT_POST, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_USERAGENT, "SomeUserAgent");
curl_setopt($ch, CURLOPT_COOKIE, 'AspxAutoDetectCookieSupport=1');
$output = curl_exec($ch);
curl_close($ch);
return $output;
}
