php - CURL 与 get 和 post 保持会话

Question

我已经用帖子登录了一个网站，没关系。当我使用 GET 方法获取该站点时，一切正常（返回“您好，用户名！”等），但是当我尝试向该站点发送帖子时，它会将我重定向到登录页面。似乎 curl 不会使用 post 方法发送 cookie 会话。如何解决？我的代码：

public function curlInit()
{
    $this->_ch = null;
    $this->_ch = curl_init();
    curl_setopt($this->_ch, CURLOPT_USERAGENT, $this->_userAgent);
    curl_setopt($this->_ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($this->_ch, CURLOPT_CONNECTTIMEOUT, 25);
    curl_setopt($this->_ch, CURLOPT_VERBOSE, 1);
    curl_setopt($this->_ch, CURLOPT_COOKIEFILE, dirname(__FILE__) . '/cookies-jar.txt');
    curl_setopt($this->_ch, CURLOPT_COOKIEJAR, dirname(__FILE__) . '/cookies-jar.txt');
    curl_setopt($this->_ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($this->_ch, CURLOPT_COOKIESESSION, 1);
    curl_setopt($this->_ch, CURLOPT_HTTPHEADER, 1);
    curl_setopt($this->_ch, CURLOPT_AUTOREFERER,  1);
    if ($this->proxy)
    {
        curl_setopt ($this->_ch, CURLOPT_PROXY, $this->proxy);
    }
}
public function getPostSite($url, $data)
{
    $this->curlError = false;

    curl_setopt($this->_ch,CURLOPT_URL, $url);
    curl_setopt($this->_ch,CURLOPT_POST, 1);
    curl_setopt($this->_ch,CURLOPT_POSTFIELDS, $data);
    $result = curl_exec($this->_ch);
    if (curl_errno($this->_ch))
    {
        $this->curlError = curl_errno($this->_ch);
        return false;
    }
    return $result;
}
public function  getGetSite($url)
{
    curl_setopt($this->_ch,CURLOPT_POST, 0);
    curl_setopt($this->_ch, CURLOPT_URL, $url);
    $data = curl_exec($this->_ch);
    return $data;
}
