使用超时后:

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

我收到了此超时错误:

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

我该怎么办?

那是Timeout的预期行为。如果块花费的时间太长,则会终止执行并抛出异常。

您可能希望捕获异常并正确处理它:

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

uri = URI.parse("https://example.com")
        # Full control
        http = Net::HTTP.new(uri.host, uri.port)
        http.use_ssl = true
        #http.read_timeout = 500
        request = Net::HTTP::Post.new(uri.request_uri)
        request.set_form_data({"locationcode" => "999", "sublocationcode" => "1"})
        response = http.request(request)
        render :json => response.body
