Answer 1

您可以使用字符串拆分方法。最简单的方法。

ruby-1.9.2-p290 :004 > a = 'http://share.findmespot.com/shared/faces/viewspots.jsp?glId=0rEE45o3ERRryMevW5teqS9gkNI'
 => "http://share.findmespot.com/shared/faces/viewspots.jsp?glId=0rEE45o3ERRryMevW5teqS9gkNI" 
ruby-1.9.2-p290 :005 > b = a.split('=')[1]
 => "0rEE45o3ERRryMevW5teqS9gkNI"
