诺基亚 HTTP_REFERER 问题

[英]Nokia HTTP_REFERER issue

原文 2009-06-16 09:32:26 3 3 php/ mobile/ nokia

We've developing mobile application using CodeIgniter PHP framework.我们使用 CodeIgniter PHP 框架开发移动应用程序。 App was tested on several hardware phones and emulators.应用程序在多个硬件手机和模拟器上进行了测试。 Everything works fine everywhere - except Nokia S40 built-in browser.一切都在任何地方都很好——除了诺基亚 S40 的内置浏览器。 When browsing via thatbrowser, it reveals that $_SERVER['HTTP_REFERER'] is not set at all - even using straight PHP with no frameworks.当通过那个浏览器浏览时，它显示 $_SERVER['HTTP_REFERER'] 根本没有设置 - 即使使用没有框架的直接 PHP。 Specifically, app was tested on Nokia 3500 Classic and 6300. Also, when using Opera Mini on the same phones, all worked like a charm.具体来说，应用程序在诺基亚 3500 Classic 和 6300 上进行了测试。此外，当在同一部手机上使用 Opera Mini 时，一切都很顺利。 Server is Apache2 with PHP5, CodeIgniter 1.7, but I don't think it's a framework issue.服务器是 Apache2 PHP5，CodeIgniter 1.7，但我不认为这是一个框架问题。

Strange thing is, it seems that only a few people in the world got, or mentioned, this issue, with no answer.奇怪的是，世界上似乎只有少数人得到或提到了这个问题，没有答案。 Well, the question is - do we missing something?好吧，问题是——我们是否遗漏了什么？ Does Nokia S40 built-in browser really strips out HTTP_REFERER, or is it server issue? Nokia S40内置浏览器真的去掉了HTTP_REFERER，还是服务器问题？ What could be done to fix or mitigate it?可以做些什么来修复或减轻它？

3 个解决方案

Referers are not required to be sent by any browser.任何浏览器都不需要发送引用。 Do not build anything assuming you will be getting them from a browser;假设您将从浏览器中获取它们，请不要构建任何东西； there are other things that can block their appearance (browser plugins, security software, etc.)还有其他东西可以阻止它们的出现（浏览器插件、安全软件等）

In order for HTTP_REFERER to exist, there needs to be a HTTP_REFERER header. This header does not exist if someone types in the URL directly (ie: does not follow a link to the page).为了使 HTTP_REFERER 存在，需要有一个 HTTP_REFERER header。如果有人直接输入 URL（即：不跟随页面链接），则此 header 不存在。 It only exists when someone clicks on a link from another page.它仅在有人单击另一个页面的链接时存在。 And, some browsers don't send them.而且，某些浏览器不发送它们。

Yes, HTTP_REFERER areoptional http headers.是的，HTTP_REFERER 是可选的 http 标头。 Some carrier, or his transcoders (proxies), are deleting HTTP_REFERER header.某些运营商或其转码器（代理）正在删除 HTTP_REFERER header。
