使用Mashape拼写检查API时未初始化的常量Spell_check::Mashape (NameError)

Question

我正在尝试使用Mashape拼写检查API https://www.mashape.com/montanaflynn/spellcheck。我这样做的方式是，我创建了一个类，每当我想要使用拼写检查API时，它都会被初始化。每次我启动它并调用我在那个类中编写的方法时，我都会收到这样的错误消息，check_spell.rb:19:in 'run_script': uninitialized constant Spell_check::Mashape (NameError)，我做错了什么？

可执行文件如下所示: testSpel

#!/usr/bin/env ruby

require_relative './lib/check_url'
require_relative './lib/extract_tags'
require_relative './lib/check_spell'

def instruction 
<<EOS

# Enter the url/file to be checked
# Enter 'Q' or 'q' to exit 
# Enter 'Help' for usage information

EOS
end

def menu 
 puts instruction
 url = gets.chomp
 controller(url)
end

def controller(url)
  if url == "q" || url == "Q" 
   puts "Bye!"
  elsif url == ""
   puts "Invalid url"
   menu
  else
   check_url(url)
  end 
end

def check_url(url)
  if url.length > 0 
    test_url = Url_check.new(url)
    if test_url.validate == 1
      check_tags = Grab_text.new(url)
      text = check_tags.print_p
      check = Spell_check.new(text)
      check.run_script
    else 
      puts "#{url} is not a valid url. Please enter a valid url"
      puts menu
    end 
  end 
end 

menu

lib/check_spell.rb

require 'rubygems'
require 'unirest'
require 'open-uri'
require 'nokogiri'
require 'uri'

class Spell_check

  def initialize(sentence)
    @sentence = sentence
  end 

  def run_script
    response = Unirest.get "https://montanaflynn-spellcheck.p.mashape.com/check/?text=This+sentnce+has+some+probblems.", headers:{:X-Mashape-Key => "yPE6iL0onCmshTi11F0PM89eYtjGp1xxxeBjsnppk45Zxxx"}
    puts response
  end 
end                

Answer 1

我建议你编辑你的问题，从代码中删除你的X-Mashape-Key，因为这可能会被用来对付你。其次，因为Spell_check位于另一个模块中，所以在调用它时需要使用全名表示法。

希望这能帮上忙
