HomeBackend DevelopmentPHP TutorialIE等多TAB浏览器在一个TAB中登录后新开一个TAB打开同一网址如何判断已经登录了跳转到登陆页

之前问过这个问题,但是觉得解答不完整,看hotmail就是登录一个TAB后,打开新tab后就跳转到登录页面了。如何实现?


回复讨论(解决方案)

新开的tab相当于刷新了页面。
session等登录信息如果已经记录了,刷新页面不就是进入到登录页面了么、

我试过了没法获取到SSION,请楼上的解释一下,谢谢 

要看下你浏览器的版本。

IE8,我用相同浏览器去登录我自己的系统和hotmail结果不一样,登录hotmail的时候我打开一个TAB登录了,再打开一个tab访问hotmail直接就跳转登录。

没有人知道吗?

不知道你遇到了什么问题,至少是你没有描述清楚
你可以这样测试一下
setcookie.php

<?phpsession_start();setcookie('name', 'my');
getcookie.php
<?phpsession_start();print_r($_COOKIE);echo session_id();

先在在第一个 TAB 中执行 setcookie.php
然后在第二个 TAB 中执行 getcookie.php
看一下都有什么结果

我碰到的问题就是在一个TAB浏览器中登录了系统了,然后在同一浏览器的tab中在打开同一地址,出现登录状态,用不同帐号登录后,之前登录的帐号就变成后登录的帐号了。

新版 ie 貌似是多session的,不过除了网银,都好久没用ie了,没啥研究

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
