检查浏览器名称和版本的简单方法
有没有非常简单的方法来了解浏览器调用了控制器的操作。
我想要我的控制器的代码，如下所示：
if mighty_lib.browser.name == "Safari"
if mighty_lib.browser.version >= 5
# Glad to see you, Safari 5, there is a stunning, interactive page for you.
elsif mighty_lib.browser.version >= 4
# Glad to see you, Safari 4, there is a less advanced page for you.
end
if mighty_lib.browser.name == "Firefox"
# Quick brown fox jumps over the lazy dog
elsif mighty_lib.browser.name == "IE"
# Oh, my god ... Change your browser ! There is a "Jurassic Park" movie for you
end
Is there any really easy way to get to know, what browser has called controller's action.
I would like to have a code for my controller, like this:
if mighty_lib.browser.name == "Safari"
if mighty_lib.browser.version >= 5
# Glad to see you, Safari 5, there is a stunning, interactive page for you.
elsif mighty_lib.browser.version >= 4
# Glad to see you, Safari 4, there is a less advanced page for you.
end
if mighty_lib.browser.name == "Firefox"
# Quick brown fox jumps over the lazy dog
elsif mighty_lib.browser.name == "IE"
# Oh, my god ... Change your browser ! There is a "Jurassic Park" movie for you
end

我建议服务器不是处理不同浏览器要求的最佳位置 - 通常，使用智能 css 和（不引人注目的）javascript 根据浏览器的特定功能在客户端打开和关闭功能是更好的方法客户端而不是修复特定版本。

我找到了两个可以完成这项工作的 gem：

您可以使用这个旧插件，或者编写一些使用
request.env["的原始代码HTTP_USER_AGENT"]。另外，请查看 Ruby 论坛 上的评论。You may use this old plugin, or write some raw code that uses
request.env["HTTP_USER_AGENT"]. Also, take a look at this comment at Ruby forums.
