使用像“浏览器”这样的gem或类似的。

browser = Browser.new(:ua => "some string", :accept_language => "en-us")
browser.name        # readable browser name
browser.version
browser.safari?
browser.opera?
browser.chrome?
browser.mobile?
browser.tablet?
browser.firefox?
browser.ie?
browser.ie6?        # this goes up to 10
browser.modern?     # Webkit, Firefox 17+, IE 9+ and Opera 12+
browser.platform    # return :mac, :windows, :linux or :other
browser.mac?
browser.windows?
browser.linux?
browser.blackberry?
browser.meta        # an array with several attributes
browser.to_s        # the meta info joined by space
