php-curl-cookie相关
CURLOPT_HEADERFUNCTION 设置一个回调函数,这个函数有两个参数,第一个是cURL的资源句柄,第二个是输出的header数据。header数据的输出必须依赖这个函数,返回已写入的数据大小。
curl_setopt($ch, CURLOPT_COOKIESESSION, TRUE);
CURLOPT_COOKIESESSION 启用时curl会仅仅传递一个session cookie,忽略其他的cookie,默认状况下cURL会将所有的cookie返回给服务端。session cookie是指那些用来判断服务器端的session是否有效而存在的cookie。
To collect cookies recieved with a request, set CURLOPT_COOKIEJAR “cookieFileName”. Then use CURLOPT_COOKIEFILE “cookieFileName” to recall them in subsequent transactions.
curl_setopt($ch, CURLOPT_COOKIEJAR, “cookie.txt”);
curl_setopt($ch, CURLOPT_COOKIEFILE, “cookie.txt”);
Sometimes you can’t use CURLOPT_COOKIEJAR and CURLOPT_COOKIEFILE becoz of the server php-settings(They say u may grab any files from server using these options). Here is the solution
1)Don’t use CURLOPT_FOLLOWLOCATION
2)Use curl_setopt($ch, CURLOPT_HEADER, 1)
3)Grab from the header cookies like this:
preg_match_all(‘|Set-Cookie: (.*);|U’, $content, $results);
$cookies = implode(‘;’, $results[1]);
4)Set them using curl_setopt($ch, CURLOPT_COOKIE, $cookies);
