如何在PHP中使用curl保持会话信息？

Question

仅当我第一次登录时，才可以访问虚拟页面www.randomDomain.com/onlyForRegisteredUsers 。 所以我这样做：

...
curl_setopt($this->curl, CURLOPT_HEADER, false);
curl_setopt($this->curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($this->curl, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($this->curl, CURLOPT_HTTPPROXYTUNNEL, true);
curl_setopt($this->curl, CURLOPT_CONNECTTIMEOUT, 10);
curl_setopt($this->curl, CURLOPT_TIMEOUT, 10);
curl_setopt($this->curl, CURLOPT_USERAGENT, $this->currentUseragent;
curl_setopt($this->curl, CURLOPT_PROXY, $this->currentIP);
curl_setopt($this->curl, CURLOPT_URL, $this->currentUrl); //www.randomDomain.com/login/
curl_setopt($this->curl, CURLOPT_POST, true);
curl_setopt($this->curl, CURLOPT_POSTFIELDS, $this->currentData);
    //with login RandomUserName and pass *******
$page = curl_exec($this->curl);

在$ page中成功获得了如下结果： ...<p>Welcome back, RandomUserName!</p> 。

如何保留有关我已经登录的会话的信息，然后从www.randomDomain.com/onlyForRegisteredUsers读取内容？

你可以这样做 ：

$cookieFile = 'cookie.txt';
curl_setopt($this->curl, CURLOPT_COOKIESESSION, true);
curl_setopt($this->curl, CURLOPT_COOKIEJAR, realpath($cookieFile));
curl_setopt($this->curl, CURLOPT_COOKIEFILE, realpath($cookieFile));

注意：cookie文件必须存在，如果不存在，可以使用以下命令创建该文件：

if (!file_exists(realpath($cookieFile)))
{
    touch($cookieFile);
}
