HomeBackend DevelopmentPHP Tutorialphp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。

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AM

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values ​​and handle functions that may return null values.

How does PHP handle object cloning (clone keyword) and the __clone magic method?How does PHP handle object cloning (clone keyword) and the __clone magic method?Apr 17, 2025 am 12:24 AM

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.
