未初始化的常量Student::Net

Question

我在轨道3.0.4上工作。我打算在保存学生记录后向特定号码发送短信。下面我要提到的代码在rails2.X中运行良好，但在rails3.0.4中，我得到了一个错误：

NameError in StudentsController#create 
uninitialized constant Student::Net 

代码：

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

确保您在控制器中的某个位置有适当的require语句，或者最好在environment.rb文件或初始值设定项中：

require 'net/http'
