如果需要实现程序自动登录功能,涉及到curl时发送cookie
关键方法
curl_setopt($curl, CURLOPT_HEADER, TRUE);
设置返回response header
curl_setopt($curl, CURLOPT_COOKIE, $cookie);
设置发送的cookie内容
Demo
该方法发送请求时,获取response header中的Set-Cookie参数,获得PHPSESSID的值
private function go_login_page() {
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $this->login_page_url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($curl, CURLOPT_HEADER, TRUE);
$content = curl_exec($curl);
preg_match('/^Set-Cookie: PHPSESSID=(.*?);/m', $content, $this->phpsessid);
curl_close($curl);
}
请求登录接口,并把上一个请求中返回的cookie信息带到该请求中
private function go_login() {
$curl = curl_init();
$cookie = "PHPSESSID=" . $this->phpsessid;
$post_data = 'username=xx&password=xx';
curl_setopt($curl, CURLOPT_COOKIE, $cookie);
curl_setopt($curl, CURLOPT_URL, $this->go_login);
curl_setopt($curl, CURLOPT_POST, TRUE);
curl_setopt($curl, CURLOPT_POSTFIELDS, $post_data);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($curl, CURLOPT_HEADER, FALSE);
$content = curl_exec($curl);
curl_close($curl);
}
