未初始化的常量Student :: Net

Question

我正在使用rails 3.0.4.我打算在保存学生记录后将短信发送到特定号码.我在下面提到的代码在rails 2.X中运行良好,但在rails 3.0.4上,我收到一个错误:

NameError in StudentsController#create 
uninitialized constant Student::Net 

码:

def send_welcome_sms
  url=URI.parse("http://webaddress.com");

  #error occuring at this point
  request = Net::HTTP::Post.new(url.path)  
  message = "message goes here"
  request.set_form_data({'username'=>"abc", 'password'=>"xyz", 'to'=> "some number", 'text'=> "#{message}", 'from'=> "someone"})
  response = Net::HTTP.new(url.host, url.port).start {|http| http.request(request) }
  # If U are Behind The Proxy Comment Above Line And  Uncomment Below Line, Give The Proxy Ip & Port
  #response = Net::HTTP::Proxy("PROXY IP", PROXYPORT).new(url.host, url.port).start {|http| http.request(request) }

  case response
  when Net::HTTPSuccess
    puts response.body
  else
    response.body
    response.error!
  end
end

确保require在控制器中或者最好在environment.rb文件或初始化程序中的某处具有相应的语句:

require 'net/http'
