我正在开发Alexa技能（使用v2和javascript），并且试图对USDA API进行API GET调用。
至此，我已经从here复制/粘贴了，并且我正在使用here的USDA API示例（有一些小的更改）。作为尝试使连接正常工作并返回任何证明有效的尝试。
我当前收到的错误是： Error handled: TypeError: Cannot read property 'generalSearchInput' of undefined at Object.handle (/var/task/index.js:39:32)
at process._tickCallback (internal/process/next_tick.js:68:7)
直接在错误发生之前，我得到了返回： USDA API中关于干酪的每个条目，即[ 控制台日志告诉我，我正在从呼叫中收到数据，因此我知道它正在工作。我的问题是：如何将 我正在寻找的 我收到的答复是：console.log(response)中的[[WAY too too]]。我只想要第一个，甚至就是名字。speechOutput设置为所需的特定信息，而不是返回的整个API对象？speechOutput应该说：对不起，我无法按您的要求去做。请再试一次
