useragents-rb
Usually, spiders must disguise themselves with plenty of User-Agents, for some
servers are smart. The gem useragents can give you that!
It has frequently-used browsers such as Chrome, Firefox, Internet Explorer, Safari,
Opera and so on, with frequently-used versions.
The usage is simple, just install the gem at first, then require 'useragents,
and at last, UserAgents.rand() works for you!
Enjoy it!
Usage
gem install useragentsrequire 'useragents'
# Generate a random useragent for you
UserAgents.rand()
