【问题描述】：

我使用以下代码登录网站

$postData = array("login" => "Prijava", "loginEmail" => "****@****.***", "password" => "*****t", "signonForwardAction" => "/press/cm/si.press.viasat.tv?cc=si&lc=si");

$URL = "http://si.press.viasat.tv/press/cm/1.167?cc=si&lc=si";

$connection = curl_init();
curl_setopt($connection, CURLOPT_URL, $URL);
curl_setopt($connection, CURLOPT_POST, 1);

curl_setopt($connection, CURLOPT_POSTFIELDS, $postData);

curl_setopt($connection, CURLOPT_FOLLOWLOCATION, true);

curl_setopt($connection, CURLOPT_REFERER, "http://si.press.viasat.tv");
curl_setopt($connection, CURLOPT_AUTOREFERER, true);
curl_setopt($connection, CURLOPT_HEADER, true);
curl_setopt($connection, CURLOPT_POSTREDIR, 2);

curl_setopt($connection,CURLOPT_COOKIEJAR, "C:\@DEV\TextALG\cookie.txt");
curl_setopt($connection,CURLOPT_COOKIEFILE, "C:\@DEV\TextALG\cookie.txt");

curl_exec($connection);



curl_close($connection);

问题是（在 Firebug 中发现）在登录后站点重定向到 URL（响应：302）。结果我又得到了登录屏幕。

我得到这样的 cookie：

# Netscape HTTP Cookie File
# http://curl.haxx.se/rfc/cookie_spec.html
# This file was generated by libcurl! Edit at your own risk.

si.press.viasat.tv  FALSE   /press  FALSE   0   JSESSIONID  00FC3DCA4CFD806CDEBE2CAA7E999463

有什么想法吗？

【问题讨论】：

它适用于没有 302 响应的网站..
你试过curl_setopt($connection, CURLOPT_HEADER, false);

【解决方案1】：

尝试添加以下选项

CURLOPT_FOLLOWLOCATION => TRUE,     // follow redirects         
CURLOPT_MAXREDIRS      => 10,       // stop after 10 redirects

【解决方案2】：

我尝试了不同的逻辑（浏览逻辑，现在可以了！）

$ch = curl_init();
$randnum = rand(1,5000);
curl_setopt($ch, CURLOPT_COOKIEJAR, "/tmp/cookiejar-$randnum");
curl_setopt($ch, CURLOPT_COOKIEFILE, "/tmp/cookiejar-$randnum");
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1");
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 0);


curl_setopt($ch, CURLOPT_URL,$URL);
$page = curl_exec($ch);

preg_match("/action=\"(.*)\"/", $page, $action);
preg_match("/signonForwardAction\" type=\"hidden\" value=\"(.*)\"/", $page, $signonFA);

$action = $action[1];
$signonFA = $signonFA[1];
$postData['signonForwardAction'] = $signonFA;


curl_setopt($ch, CURLOPT_URL,$URL.$action);
curl_setopt($ch, CURLOPT_REFERER, $URL);
curl_setopt($ch, CURLOPT_HTTPHEADER, Array("Content-Type: application/x-www-form-urlencoded"));
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,http_build_query($postData));
$page = curl_exec($ch);

基本思路是访问站点，设置 cookie，然后将数据（必须是字符串而不是数组！）发布到站点（通过 $action 获取），然后继续爬取站点！
