IE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

Jun 23, 2016 pm 02:20 PM

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');
Copy after login
getcookie.php
<?phpsession_start();print_r($_COOKIE);echo session_id();
Copy after login

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

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

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,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
