捲曲重定向，不工作？

Question

我使用下面的代碼：

$agent= 'Mozilla/5.0 (Windows; U; Windows NT 5.1; pl; rv:1.9) Gecko/2008052906 Firefox/3.0'; 

$ch = curl_init(); 

curl_setopt($ch, CURLOPT_USERAGENT, $agent); 

curl_setopt($ch, CURLOPT_URL, "www.example.com"); 

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 

curl_setopt($ch, CURLOPT_HEADER, 0); 

$output = curl_exec($ch); 

echo $output; 

但它重定向到這樣的：

http://localhost/aide.do?sht=_aide_cookies_ 

而不是到URL頁面。

任何人都可以幫我解決我的問題嗎？

Answer 1

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 

http://docs.php.net/function.curl-setopt說：

CURLOPT_FOLLOWLOCATION
TRUE遵循任何「位置：」頭，服務器發送的HTTP標頭的一部分（注意這是遞歸的，PHP將遵循儘可能多的「位置：「發送它的標題，除非設置了CURLOPT_MAXREDIRS）。

Answer 2

如果它是由URL重定向纔看到下面的代碼，我已經證明它給你，讓你可以直接輕鬆地使用它&，你已經兩個主要的捲曲選項控制URL重定向（CURLOPT_FOLLOWLOCATION/CURLOPT_MAXREDIRS）：

// create a new cURL resource 
$ch = curl_init(); 

// The URL to fetch. This can also be set when initializing a session with curl_init(). 
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/"); 

// The contents of the "User-Agent: " header to be used in a HTTP request. 
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; pl; rv:1.9) Gecko/2008052906 Firefox/3.0"); 

// TRUE to include the header in the output. 
curl_setopt($ch, CURLOPT_HEADER, false); 

// TRUE to return the transfer as a string of the return value of curl_exec() instead of outputting it out directly. 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 

// TRUE to follow any "Location: " header that the server sends as part of the HTTP header (note this is recursive, PHP will follow as many "Location: " headers that it is sent, unless CURLOPT_MAXREDIRS is set). 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 

// The maximum amount of HTTP redirections to follow. Use this option alongside CURLOPT_FOLLOWLOCATION. 
curl_setopt($ch, CURLOPT_MAXREDIRS, 10); 

// grab URL and pass it to the output variable 
$output = curl_exec($ch); 

// close cURL resource, and free up system resources 
curl_close($ch); 

// Print the output from our variable to the browser 
print_r($output); 

上述代碼處理URL重定向問題，但它不處理cookie（您的本地主機URL似乎是處理cookie）。如果要對付來自卷邊資源餅乾，那麼你可能得給下面捲曲選項一看： CURLOPT_COOKIE CURLOPT_COOKIEFILE CURLOPT_COOKIEJAR
