我正在编写一个URL刮板(只是名称和说明),并试图处理301重定向。PHP Array搜索返回值时返回false数组
现在,我检查标题,如果不是200,我尝试在标题中找到要重定向到的位置。我的问题出现了,因为尽管我在那里看到它,但array_search不返回位置值所在的键。
这是代码片段:
if(strpos($url_headers[0], "200") !== false){
echo "in here";
return $url;
}else{
print_r($url_headers);
//look for location
$location_key = array_search("Location: ", $url_headers);
echo "Location Key: " . $location_key;
$redirect_string = $url_headers[$location_key];
$clean_url = str_replace("Location: ", "", $redirect_string);
return $clean_url;
}
的这个输出是:
Array ([0] => HTTP/1.0 301 Moved Permanently [1] => Location: http://www.google.com/ [2] => Content-Type: text/html; charset=UTF-8 [3] => Date: Wed, 13 Feb 2013 03:30:00 GMT [4] => Expires: Fri, 15 Mar 2013 03:30:00 GMT [5] => Cache-Control: public, max-age=2592000 [6] => Server: gws [7] => Content-Length: 219 [8] => X-XSS-Protection: 1; mode=block [9] => X-Frame-Options: SAMEORIGIN [10] => HTTP/1.0 200 OK [11] => Date: Wed, 13 Feb 2013 03:30:00 GMT [12] => Expires: -1 [13] => Cache-Control: private, max-age=0 [14] => Content-Type: text/html; charset=ISO-8859-1 [15] => Set-Cookie: PREF=ID=fe86e29432d4e240:FF=0:TM=1360726200:LM=1360726200:S=Wg8VEU7kc7UtcKc-; expires=Fri, 13-Feb-2015 03:30:00 GMT; path=/; domain=.google.com [16] => Set-Cookie: NID=67=KH8Zu8EpKjrhje8nD0lk_868mqvQr9pGwsAsaUuPDD_PRUgohJHoOkdlyYEHWmohUtndyENDJ0oZq8pC1aqOg20anXpUn5btQX5GYM6kYlgMhYxIPajtGp9KymmMDO1Y; expires=Thu, 15-Aug-2013 03:30:00 GMT; path=/; domain=.google.com; HttpOnly [17] => P3P: CP="This is not a P3P policy!

我在做什么错?在抓取用户提供的链接时有没有更好的方式来处理重定向?
不会我有一个自动的重定向头解析机制? – 2013-02-13 03:36:22
尝试实施卷曲,如果存在自动重定向机制,则不会启动:请参阅http://tryecruit.com/app/app.php?action=new&object=resource&url=google.com – 2013-02-13 03:56:27
