Apache2 Ubuntu Navigator缺少功能
我一直在开发带有Apache2的Web应用程序，该应用程序最终应该在Raspberry Pi上运行。
最初的开发和测试是在Arch Linux机器（带有HTTPD）上进行的，然后在PI上转移并进一步调试。
最近，我已经开始使用JavaScript和Navigator.getGamePads（）函数将控制器输入到Web应用中。所有在我的拱机上的预期工作，但是当我将代码传输到PI时，我会收到“ Navigator.getGamePads”不是函数的错误。
在进行进一步调查时，我确实可以确认使用Firefox JavaScript控制台缺少该功能，并且Navigator对象本身在两个页面（Arch版本和PI版本）中看起来完全不同。

两个屏幕截图均在同一个屏幕上拍摄机器，同一浏览器，页面从两个位置加载在不同的选项卡中。
有人遇到过类似的问题吗？
I've been developing a web app with Apache2 which is supposed to run on a Raspberry pi running Ubuntu in the end.
Initial developing and testing is done on an Arch Linux machine (with httpd) and then transferred and further debugged on the pi.
Recently, I've started implementing controller input into the web app using javascript and the navigator.getGamepads() function. Everything working as expected on my Arch machine, but when i transfer the code to the pi, i get a "navigator.getGamepads is not a function" error.
When further investigating, I can indeed confirm that the function is missing using the firefox javascript console, as well as that the navigator object itself looks quite different for both pages (the Arch version, and the pi version).

Both screenshots are taken on the same machine, same browser, with the page loaded from both places in different tabs.
Has anyone experienced similar problem, and is there a fix?

事实证明，除非通过SSL（HTTPS）处理连接，否则浏览器（Firefox）不会公开所有导航器功能。
Found an answer after some tinkering.
Turns out the browser (Firefox) will not expose all navigator functions unless the connection is handled through SSL (https).
