Question

我正在使用对话流程实现，Google上的操作来创建聊天机器人，并将其托管在AWS Lambda中。我正在尝试请求用户权限，但是当我尝试添加一些Google动作（例如权限）时遇到问题。

我尝试了对话框流程示例在这里所做的事情：

https://github.com/dialogflow/fulfillment-actions-library-nodejs/blob/master/functions/index.js

但是，由于我使用的是AWS Lambda，因此我没有遵循确切的代码，也许我缺少了一些东西。

 router.post('/', (request, response) => {
  const agent = new WebhookClient({ request, response });
  console.log('Dialogflow Request headers: ' + JSON.stringify(request.headers));
  console.log('Dialogflow Request body: ' + JSON.stringify(request.body));

  function welcome(agent) {
    agent.add(`Welcome to the webhook`);
  }

  function fallback(agent) {
    agent.add(`I didn't understand`);
    agent.add(`I'm sorry, can you try again?`);
  } 

function locationIntent(agent) {
    let conv = agent.conv();
    conv.ask(new Permission({
      context: 'To give results in your area',
      permissions: 'DEVICE_PRECISE_LOCATION',
    }))
    agent.add(conv);
  }

// Run the proper function handler based on the matched Dialogflow intent name
  let intentMap = new Map();
  intentMap.set('Default Welcome Intent', welcome);
  intentMap.set('Default Fallback Intent', fallback);

  if (agent.requestSource === agent.ACTIONS_ON_GOOGLE) {
    intentMap.set('location', locationIntent);
  } else {
    intentMap.set(null, other);
  }
  agent.handleRequest(intentMap);
});

app.use('/', router);

module.exports = app;

我已经用过了

const { WebhookClient} = require('dialogflow-fulfillment');

const { dialogflow,
  SimpleResponse,
  BasicCard,
  Suggestions,
  Permission,
  UpdatePermission,
  RegisterUpdate,
  Carousel,
} = require('actions-on-google');

我的依赖项是：

  "dependencies": {
    "actions-on-google": "^2.5.0",
    "aws-serverless-express": "^3.3.5",
    "body-parser": "^1.18.3",
    "compression": "^1.7.3",
    "cors": "^2.8.5",
    "dialogflow": "^4.0.3",
    "dialogflow-fulfillment": "^0.6.1",
    "express": "^4.16.4",
    "googleapis": "^27.0.0"
  }

我从dialogflow博客的这篇文章中获得许可意图： https://blog.dialogflow.com/post/fulfillment-library-beta/

我检查了aws-lambda中的日志，发现了这一点：

TypeError：无法在读取未定义的属性'forEach' V2Agent.addActionsOnGoogle _

这发生在我做agent.add(conv)时。如果我这样做，agent.add("This is location permission intent");可以工作。我希望获得许可，以后再用于一些坐标

我正在使用节点v10.15.0

aws-lambda中的Stracktrace：

注意：我已经尝试使用Google上的其他元素，例如轮播，但失败了。这使我觉得agent.add或conv

出了问题

这强烈表明，尽管列出了相关性，但您使用的是dialogflow-fulfillment库的旧版本。确保您安装了最新版本

npm update

TypeError：无法读取V2Agent.addActionsOnGoogle _
