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。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
