php使用CURL不依赖COOKIEJAR获取COOKIE的方法
本文实例讲述了php使用CURL不依赖COOKIEJAR获取COOKIE的方法。分享给大家供大家参考。具体分析如下:
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];
希望本文所述对大家的php程序设计有所帮助。
