使用超时后：

status = Timeout::timeout(5) {
  # Something that should be interrupted if it takes too much time...
}

我有超时错误：

/Users/galharth/.rvm/rubies/ruby-1.9.2-p136/lib/ruby/1.9.1/net/http.rb:644:in `initialize': execution expired (Timeout::Error)
    from /Users/galharth/.rvm/rubies/ruby-1.9.2-p136/lib/ruby/1.9.1/net/http.rb:644:in `open'
    from /Users/galharth/.rvm/rubies/ruby-1.9.2-p136/lib/ruby/1.9.1/net/http.rb:644:in `block in connect'

    from /Users/galharth/.rvm/gems/ruby-1.9.2-p136/gems/mechanize-1.0.0/lib/mechanize.rb:527:in `fetch_page'
    from /Users/galharth/.rvm/gems/ruby-1.9.2-p136/gems/mechanize-1.0.0/lib/mechanize.rb:259:in `get'

我该怎么办？

解决方法

那么这是 Timeout的预期行为.如果块花费的时间太长,它的执行将被终止并引发异常.

你可能想要捕获异常并适当地处理它：

require 'timeout'
begin
  status = Timeout::timeout(5) {
    # Something that should be interrupted if it takes too much time...
  }
rescue Timeout::Error
  puts 'That took too long,exiting...'
end
