本文章来给大家介绍php CURL不使用文件存取COOKIE一个实例,希望此方示对各位同学会有所帮助哦。

CURL是一个非常实用的PHP扩展,模拟用户登录时经常需要存取COOKIE信息,而使用COOKIEJAR和COOKIEFILE会产生两次或两次以上的I/O操作,性能效率自不必说,在第三方云应用平台(BAE SAE等),有时还需要操作STORAGE来实现存取COOKIE,比较麻烦,今天介绍一个CURL不使用文件存取COOKIE的方法:
 
COOKIEJAR/COOKIEFILE方式:

 代码如下 复制代码

/*-----保存COOKIE-----*/
$url = 'www.bKjia.c0m'; //url地址
$post = "id=user&pwd=123456"; //POST数据
$cookie = tempnam('./','cookie'); //cookie临时文件
$ch = curl_init($url); //初始化
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); //返回获取的输出文本流
curl_setopt($ch,CURLOPT_POSTFIELDS,$post); //发送POST数据
curl_setopt($ch,CURLOPT_COOKIEJAR,$cookie); //保存获得的cookie
curl_exec($ch); //执行curl
curl_close($ch); //关闭curl

/*-----使用COOKIE-----*/
curl_setopt($ch,CURLOPT_COOKIEFILE,$cookie);

新方式(无I/O操作):

 代码如下 复制代码


/*-----保存COOKIE-----*/
$url = 'www.bKjia.c0m'; //url地址
$post = "id=user&pwd=123456"; //POST数据
$cookie = tempnam('./','cookie'); //cookie临时文件
$ch = curl_init($url); //初始化
curl_setopt($ch,CURLOPT_HEADER,1); //将头文件的信息作为数据流输出
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); //返回获取的输出文本流
curl_setopt($ch,CURLOPT_POSTFIELDS,$post); //发送POST数据
$content = curl_exec($ch); //执行curl并赋值给$content
preg_match('/Set-Cookie:(.*);/iU',$content,$str); //正则匹配
$cookie = $str[1]; //获得COOKIE(SESSIONID)
curl_close($ch); //关闭curl

/*-----使用COOKIE-----*/
curl_setopt($ch,CURLOPT_COOKIE,$cookie);

/*-----保存COOKIE-----*/
$url = 'www.bKjia.c0m'; //url地址
$post = "id=user&pwd=123456"; //POST数据
$cookie = tempnam('./','cookie'); //cookie临时文件
$ch = curl_init($url); //初始化
curl_setopt($ch,CURLOPT_HEADER,1); //将头文件的信息作为数据流输出
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); //返回获取的输出文本流
curl_setopt($ch,CURLOPT_POSTFIELDS,$post); //发送POST数据
$content = curl_exec($ch); //执行curl并赋值给$content
preg_match('/Set-Cookie:(.*);/iU',$content,$str); //正则匹配
$cookie = $str[1]; //获得COOKIE(SESSIONID)
curl_close($ch); //关闭curl

/*-----使用COOKIE-----*/
curl_setopt($ch,CURLOPT_COOKIE,$cookie);
