大神在吗?PHP关于session和cookie的修改看不懂啊!

Jun 23, 2016 pm 01:59 PM

帮忙看下下面两个功能是否修改了SESSIONID,为什么我始终获取不到正确的id呢?每次浏览器生成的都是固定的id,而我获取到的id都是在变化的。

/** * session管理函数 * @param string|array $name session名称 如果为数组则表示进行session设置 * @param mixed $value session值 * @return mixed */function session($name,$value='') {    $prefix   =  C('SESSION_PREFIX');    if(is_array($name)) { // session初始化 在session_start 之前调用        if(isset($name['prefix'])) C('SESSION_PREFIX',$name['prefix']);        if(C('VAR_SESSION_ID') && isset($_REQUEST[C('VAR_SESSION_ID')])){            session_id($_REQUEST[C('VAR_SESSION_ID')]);        }elseif(isset($name['id'])) {            session_id($name['id']);        }        ini_set('session.auto_start', 0);        if(isset($name['name']))            session_name($name['name']);        if(isset($name['path']))            session_save_path($name['path']);        if(isset($name['domain']))          ini_set('session.cookie_domain', $name['domain']);        if(isset($name['expire']))          ini_set('session.gc_maxlifetime', $name['expire']);        if(isset($name['use_trans_sid']))   ini_set('session.use_trans_sid', $name['use_trans_sid']?1:0);        if(isset($name['use_cookies']))     ini_set('session.use_cookies', $name['use_cookies']?1:0);        if(isset($name['cache_limiter']))   session_cache_limiter($name['cache_limiter']);        if(isset($name['cache_expire']))    session_cache_expire($name['cache_expire']);

真可怕

真可怕 你在说我么……

一大堆if else


真可怕 你在说我么……

我是说写这段代码的人太逗了

一大堆if else phpthink



真可怕 你在说我么……

我是说写这段代码的人太逗了 phpthink写的啊

thinkphp吧,那里来的phpthink

thinkphp吧,那里来的phpthink 哦 对 你说的对 帮忙看看

这不是 thinkphp 的内置函数吗?
你到底想干什么?

这不是 thinkphp 的内置函数吗?
你到底想干什么? 还是之前的问题没有解决,怀疑不是客户端程序的问题,而是thinkPHP的内部机制问题

你用浏览器能正确访问吗?

你用浏览器能正确访问吗? 可以的啊

那就说明是你的客户端写的有问题

那就说明是你的客户端写的有问题 可是php后端修改了session和cookie啊

无论后端是否修改了session和cookie
只要用浏览器能正常访问,就说说明系统是正常工作的
也就印证了你的客户端存在问题:不能正确的获得cookie

问题没有描述清楚?

无论后端是否修改了session和cookie

也就印证了你的客户端存在问题:不能正确的获得cookie 通常情况下,浏览器产生的session是不固定的吧!可是我这边都是固定的,我查了下说是thinkPHP的问题,配置文件php.ini修改了也无效,所以我觉得是php后端的问题。

问题没有描述清楚? 哪里不明白,请问

session 是服务端产生的,只要浏览器不离开这个网站,session id 就不会变化


问题没有描述清楚? 哪里不明白,请问
thinkphp的session使用也还是依据php的session方法调用。

session 是服务端产生的,只要浏览器不离开这个网站,session id 就不会变化

session_id();
Copy after login
这个不是修改sessionid的函数么



问题没有描述清楚? 哪里不明白,请问
thinkphp的session使用也还是依据php的session方法调用。 怀疑他修改了session

你最好结合楼主的另一帖一起看!
楼主用C#写了个模拟登陆程序,现不能维持登录状态
因此怀疑是 thinkphp 的问题



问题没有描述清楚? 哪里不明白,请问
thinkphp的session使用也还是依据php的session方法调用。

无论 sessionid 是否被改变
你的客户端只需要能正确的读取并发送cookie就可以了

你的客户端只是 模拟浏览器的行为

你的客户端只是 模拟浏览器的行为 好吧!可是C#板块没有人给我解答……

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Apr 17, 2025 am 12:06 AM

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values ​​to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
