Symfony2 - 如何检查我们是否被移动设备调用 [英] Symfony2 - How to check if we are being called from a mobile device

问题描述

使用 Symfony2，无论我是从移动设备还是从桌面网络浏览器调用，我都需要检查控制器.

Using Symfony2, I need to check in the controller wether I am being called from a mobile device or from a desktop web browser.

根据请求的来源，根据屏幕大小和条件呈现不同的树枝模板.

Depending on the origin of the request, render different twig templates according to the screen sizes and conditions.

这样做的好方法是什么?我们在控制器中有什么可以检查这个?

What would be a good approach to do this? What do we have in the Controller to check this?

推荐答案

我确信 Symfony 也有一些封装的命令来执行此操作，但是:

I'm sure Symfony has some wrapped command to do this as well but:

$_SERVER['HTTP_USER_AGENT']

将为您提供 user-agent 字符串，该字符串包含字符串Android verNum".

will give you the user-agent string which tents to have a string "Android verNum".
