取得要跳转的url,方便下一步操作。有时候我们不需要跳转的内容,而更需要跳转的网址就可以使用它了

//获得要跳转的网址,进行下一步操作
function  curl_post_302($url,$data=null) {

	$ch = curl_init();
	curl_setopt($ch,  CURLOPT_RETURNTRANSFER, 1);
	curl_setopt($ch, CURLOPT_URL,  $url);
	curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
	curl_setopt($ch, CURLOPT_TIMEOUT, 30);
	curl_setopt($ch, CURLOPT_POST, 1);
	curl_setopt($ch,  CURLOPT_POSTFIELDS, $vars);
	curl_setopt($ch,  CURLOPT_FOLLOWLOCATION, 1); // 获取转向后的内容          
	$data = curl_exec($ch);
	$Headers =  curl_getinfo($ch);		 
	curl_close($ch);
	if ($data != $Headers){		 
		return $Headers["url"];		  
	}else{
		return false;
	}

}
echo curl_post_302($302url);//得到要跳转的地址
