Ruby on rails 没有得到具体的答案

我正在使用ruby并使用一个名为food2fork.com的api 我有两个文件 recipes_controller.rb和recipes.rb

第二个文件是recipes_controller.rb

但当我在命令行中运行recipes_controller.rb文件时，我得到了一个错误

    `

似乎您发送了错误的api密钥

试着这样做：

class Recipe
    include HTTParty

    key_value = ENV['FOOD2FORK_KEY'] || 'YOUR_API_KEY_HERE'

    base_uri "http://food2fork.com/api"
    default_params key: key_value
    default_options.update(verify: false)
    format :json

    def self.for(search_string)
        get('/search', { query: { q: search_string}})["recipes"]
    end
end

---

似乎响应不是JSON。检查是否可以使用提供的密钥手动访问URL。此外，ENV[a4211b7526158c71df283b3b5097eb36]末端的空间是否也是有意的？否则，这可能会导致将nil值作为键传递给请求。当我尝试手动访问它时，它返回403禁止是的，它是这样工作的。您能告诉我出了什么问题吗，因为在此之前，我还使用了提供给我的正确api键。当我注册时？？如果字符串ENV['FOOD2FORK\u key'，则我的脚本设置默认键if ENV key为空，如果字符串ENV['FOOD2FORK\u key']| |“YOUR_API_KEY_HERE”可以工作，但string ENV['FOOD2FORK_KEY']不能工作。这意味着您的ENV中没有FOOD2FORK_KEY，因为您必须在启动脚本之前在环境中设置它。简单例子
