CURL不依赖COOKIEJAR获取COOKIE

PHP中CURL类是一个非常牛逼的工具类,具体怎么牛逼就不啰嗦了。
对于COOKIE,CURL类也有很不错的支持,但不够灵活,并未能通过现成的方法以变量的方法获取到,而以要通过以下方法实现。

// 把COOKIE保存至cookie.txt
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookie.txt');
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');

先把COOKIE保存文件,调用的时候还得读取文件,这样意味着两次的IO操作,效率如何,不用说大家都清楚了。
那么有没有办法可以绕过写读文件呢?不卖关子,直接上代码:

// 初始化CURL
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
// 获取头部信息
curl_setopt($ch, CURLOPT_HEADER, 1);
// 返回原生的(Raw)输出
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// 执行并获取返回结果
$content = curl_exec($ch);
// 关闭CURL
curl_close($ch);
// 解析HTTP数据流
list($header, $body) = explode("\r\n\r\n", $content);
// 解析COOKIE
preg_match("/set\-cookie:([^\r\n]*)/i", $header, $matches);
// 后面用CURL提交的时候可以直接使用
// curl_setopt($ch, CURLOPT_COOKIE, $cookie);
$cookie = $matches[1];

打完收工!欢迎大家来喷!

GET用法:

$curl = new Curl();
$curl->get(‘http://www.hdj.me/’);

POST用法

$curl = new Curl();
$curl->get(‘http://www.hdj.me/’, ‘p=1&time=0’);
