将 Dialogflow Conversation 与 Fulfillment SDK 集成时出现异常

Question

我正在使用 Node.js Fulfillment SDK (https://github.com/dialogflow/dialogflow-fulfillment-nodejs)，我想集成 de DialogflowConversation 以访问用户存储。

我正在尝试使用这个简单的代码：

let conv = agent.conv();
conv.ask("HEY");
agent.add(conv);

但是服务器失败并出现此异常：

Error: No responses defined for platform: ACTIONS_ON_GOOGLE
    at V2Agent.sendResponses_ (/srv/node_modules/dialogflow-fulfillment/src/v2-agent.js:243:13)
    at WebhookClient.send_ (/srv/node_modules/dialogflow-fulfillment/src/dialogflow-fulfillment.js:505:17)
    at promise.then (/srv/node_modules/dialogflow-fulfillment/src/dialogflow-fulfillment.js:316:38)
    at <anonymous>
    at process._tickDomainCallback (internal/process/next_tick.js:228:7)

我目前正在使用这个库：

"dependencies": {
    "firebase-admin": "^5.13.1",
    "firebase-functions": "^2.0.2",
    "dialogflow-fulfillment": "^0.6.1",
    "actions-on-google": "^2.5.0",
    "i18n": "^0.8.3"
  }

我做错了什么？

谢谢

Answer 1

我猜 this 是您正在做的事情，导致了上述错误。尝试仅使用 actions-on-google.

这应该可以解决您的错误：

agent.add("HEY");

要访问 user storage，请使用 actions-on-google 库，如下所示：

'use strict';
const {
  dialogflow,
} = require('actions-on-google'); // Import the firebase-functions package for deployment.
const functions = require('firebase-functions'); // Instantiate the Dialogflow client.
const app = dialogflow({
  debug: true
});

app.intent('WELCOME', (conv) => {

  conv.data.count = 1;
  conv.ask('Hi there, what can I help you with today?');

});

检查相似的问题#151 and #160 in the dialogflow-fulfillment-nodejs github repo. It seems to be addressing your problem. Perhaps you could chime in there and provide insights or temporarily use the branch that might have fixed your issue: https://github.com/dialogflow/dialogflow-fulfillment-nodejs/commit/c5f1555e05d4abbc20dd9b39f6edf88249fe4aa1 (referred to in PR #179)

npm install --save dialogflow/dialogflow-fulfillment-nodejs#c5f155

如果您只打算支持 Google 助手作为集成，最好使用 actions-on-google SDK。它对响应和交互有更丰富的支持。
