ReferenceError:data is not defined in at exports.action

Question

我正在根据 API.AI 意图编写一个动作，该动作解析请求并从请求中提取起点和终点。问题是它抛出引用错误并显示数据未定义。

ReferenceError: orginalData is not defined
at exports.distanceCalculator.functions.https.onRequest (/user_code/index.js:16:43)
at cloudFunction (/user_code/node_modules/firebase-functions/lib/providers/https.js:26:47)

index.js

'use strict';

process.env.DEBUG = 'actions-on-google:*';
const App = require('actions-on-google').ApiAiApp;
const functions = require('firebase-functions');

exports.distanceCalculator=functions.https.onRequest((request,response) =>{
  const app = new App({request, response});
  console.log('Request headers: ' + JSON.stringify(request.headers));
  console.log('Request body: ' + JSON.stringify(request.body));
  var reJson,distance,duration,resText,reSon;
  var request=require('request');
  var orginalData=JSON.parse(JSON.stringify(request.body || null);
  console.log("The data received is: "+originalData);
  var origin=orginalData.result.parameters.geo_city;
  var destination=orginalData.result.parameters.geo_city;
  var travelMode='driving';
  var reqURL="https://maps.googleapis.com/maps/api/distancematrix/json?origins="+origin+"&destinations="+destination+"&mode="+travelMode;

  //Logger
  console.log('Origin: '+origin);
  console.log('Destination: '+destination);
  console.log('Travel Mode: '+travelMode);
  console.log('Request Url: '+reqURL);

  function disCal(app){
    //Google Maps API call
  request(reqURL,function(error,response,body){
    reJson=JSON.parse(body);
    distance=reJson.rows[0].elements[0].distance.text;
    duration=reJson.rows[0].elements[0].duration.text;
    resText="The distance between "+origin+" and "+destination+" is "+distance+" and it would take you "+duration+" to reach there"
  });

  console.log(global.resText);

     global.reSon=JSON.parse('{"displayText": global.resText}');
    app.post('/webhook', (req, res) => 
      {
        var reSon=JSON.parse('{"displayText": global.resText}');
        return res.json(reSon);
        });
    app.tell(reSon);
    return res.json(reSon);
  }
  let actionMap=new Map();
  actionMap.set('cities.distance',disCal);
  app.handleRequest(actionMap);
});

错误消息告诉您一切 - 哪里出了问题以及确切的行。

注意：

orginalData !== originalData

像 ESLint 这样的好 linter 可以帮助你避免这样的错误。参见：

http://eslint.org/

遵循良好的风格指南也会对您有很大帮助。例如：
