PHP curl可以从服务器端模拟一个http请求,例如抓取网页、模拟登陆等。根据选项设置,可以在curl_exec的返回结果中获取到响应头和body,但这没有响应的状态吗。想要获取状态码,需要在执行curl_exec后再通过curl_getinfo来获取。例如:
$ch = curl_init ();
curl_setopt($ch, CURLOPT_URL, 'http://www.google.com.hk');
curl_setopt($ch, CURLOPT_TIMEOUT, 200);
curl_setopt($ch, CURLOPT_HEADER, FALSE);
curl_setopt($ch, CURLOPT_NOBODY, FALSE);
#curl_setopt( $ch, CURLOPT_POSTFIELDS, "username=".$username."&password=".$password );
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, FALSE);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
curl_exec($ch);
$httpCode = curl_getinfo($ch,CURLINFO_HTTP_CODE);
