卷曲重定向，不工作？

Question

我使用下面的代码：

$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; 

但它重定向到这样的：

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

而不是到URL页面。

任何人都可以帮我解决我的问题吗？

Answer 1

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 

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

CURLOPT_FOLLOWLOCATION
TRUE遵循任何“位置：”头，服务器发送的HTTP标头的一部分（注意这是递归的，PHP将遵循尽可能多的“位置：“发送它的标题，除非设置了CURLOPT_MAXREDIRS）。

Answer 2

如果它是由URL重定向才看到下面的代码，我已经证明它给你，让你可以直接轻松地使用它&，你已经两个主要的卷曲选项控制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); 

上述代码处理URL重定向问题，但它不处理cookie（您的本地主机URL似乎是处理cookie）。如果要对付来自卷边资源饼干，那么你可能得给下面卷曲选项一看： CURLOPT_COOKIE CURLOPT_COOKIEFILE CURLOPT_COOKIEJAR
