【问题描述】:
我正在努力在网站上检测用户代理以获得技术支持,这样用户就不需要自己找到它。这是我到目前为止所得到的,但是无论我在什么浏览器上测试它都会显示为默认的“未知”关于我出错的地方有什么建议吗?
def cyberbrowser
mybrowser = ENV["HTTP_USER_AGENT"]
case mybrowser
when /MSIE 8.0/ then "Internet Explorer V8"
when /MSIE 7.0/ then "Internet Explorer V7"
when /MSIE 6.0/ then "Internet Explorer V6.0+"
when /MSIE 5.5/ then "Internet Explorer V5.5"
when /MSIE 5.22/ then "Internet Explorer V5.22"
when /MSIE 5.0/ then "Internet Explorer V5.0+"
when /MSIE 4.0/ then "Internet Explorer V4.0+"
when /MSIE 3.0/ then "Internet Explorer V3.0+"
when /MSIE 2.0/ then "Internet Explorer V2.0+"
when /Firefox/ then "Mozilla Firefox"
when /Camino/ then "Camino"
when /Dillo/ then "Dillo"
when /Epiphany/ then "Epiphany"
when /Firebird/ then "Mozilla Firebird"

-
mybrowser.scan(/MSIE (\d.\d*)/).first将返回 IE 的版本号,如果他们不使用 IE,则返回nil。只是想我会添加。
