__EVENTTARGET在params哈希表被解析爲一個變量，並從未定義的變量。嘗試"__EVENTTARGET" => "Dt1"。

你是對的。這是我現在得到的新錯誤， /home/nikhil/.rvm/rubies/ruby-1.9.2-head/lib/ruby/1.9.1/net/http.rb:415:in'post_form' ：未定義的方法路徑爲「http://www.nitt.edu/prm/nitreg/ShowRes.aspx":String（NoMethodError） from fetch_scores.rb：27：in'

我通過更改錯誤URL到 URL = URI.parse（'http://www.nitt.edu/prm/nitreg/ShowRes.aspx'）現在我得到這個錯誤＃ Iḿnew to ruby，所以這對我來說都是新的。 – nikhil 2011-06-07 11:19:37

'require'uri'''URL = URI.Parse（「http://www.nitt.edu/prm/nitreg/ShowRes.aspx」）' – 2011-06-07 11:20:06
