HomeBackend DevelopmentPHP TutorialIE Frame 下 COOKIE SESSION失效的问题解决办法

这几天在做淘宝应用的时候碰到一个比较奇怪的问题,重要的信息在页面跳转之后总是不能保存,搞了半天才知道是session丢失的问题,搜索相关资料才发现php里面还存在session在ie的IFrame下存在易丢失这样的一个问题,遂总结了几种解决办法,好话不多说,如下。

解决IE下Iframe的Cookie失效问题问题的根是由于iframe跨站点cookie被阻导致session失效。

IE6/IE7支持的P3P(Platform for Privacy Preferences Project (P3P) specification)协议默认阻止第三方无隐私安全声明的cookie

解决方法: 很简单,在要嵌入的内容中(应用页面)输出P3P的主机头声明加入如下PHP代码:

header('P3P: CP=CAO PSA OUR'); //加入P3P防止IE下写Cookeis失败

解决IE下Iframe的Session失效问题IE6/IE7支持的P3P(Platform for Privacy Preferences Project (P3P) specification)协议默认阻止第三方无隐私安全声明的cookie,Firefox目前还不支持P3P安全特 性,firefox中不存在此问题具体的解决方式是在分页的Action处理方法中加上如下代码:

header('P3P: CP="CURa ADMa DEVa PSAo PSDo OUR BUS UNI PUR INT DEM STA PRE COM NAV OTC NOI DSP COR"');

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.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
