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发送短信给特定号码。那我要提到的代码中轨下方2.X运作良好，但在轨道3.0.4，我得到一个错误：

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

请确保您有适当require声明的地方，无论是在你的控制，或者最好是在你的environment.rb文件或初始化：

require 'net/http'
