在dialogflow sdk v2上将参数发送到webhook

Question

我正在尝试将一些参数发送到dialogflow(api.ai),例如用户名,电子邮件等,但我无法弄明白.问题是我无法使用Dialogflow v2 Nodejs SDK获取/设置任何特定数据(例如用户名,电子邮件等).我试图使用queryParams.payload(v1:originalRequest),但它无法以某种方式工作.此外,我试图用数据触发自定义事件,但我无法获得响应的任何事件数据.有人知道如何在dialogFlow上发送会话对话的某些特定数据吗？

有效载荷的例子

  const projectId = 'test-bot-test-1111';
  const sessionId = user.uuid;
  const languageCode = 'en-GB';

  const sessionClient = new dialogFlow.SessionsClient();
  const sessionPath = sessionClient.sessionPath(projectId, sessionId);

  const request = {
    session: sessionPath,
    queryInput: {
      text: {
        text: query,
        languageCode
      }
    },
    queryParams: {
      payload: {
        data: {
           username: 'bob',
           email: 'bob@test.com'
        }
      }
    }
  };

  let resultReq;

  console.log('request :: ', request, '\n\n');

  try {
    resultReq = await sessionClient.detectIntent(request);
  } catch (err) {
    // eslint-disable-next-line no-console
    return console.error('ERROR:', err);
  }

事件的例子

  const projectId = 'test-bot-test-1111';
  const sessionId = user.uuid;
  const languageCode = 'en-GB';

  const sessionClient = new dialogFlow.SessionsClient();
  const sessionPath = sessionClient.sessionPath(projectId, sessionId);

const request = {
    session: sessionPath,
    queryInput: {
      event: {
        name: 'custom_event',
        languageCode,
        parameters: {
          name: 'sam',
          user_name: 'sam',
          a: 'saaaa'
        }
      }
    },
    queryParams: {
      payload: {
        data: user
      }
    }
  };

  let resultReq;

  console.log('request :: ', request, '\n\n');

  try {
    resultReq = await sessionClient.detectIntent(request);
  } catch (err) {
    // eslint-disable-next-line no-console
    return console.error('ERROR:', err);
  }

Dialogflow的v2 API使用gRPC并且有一些怪癖,其中一个是你遇到过的.如果您查看Node.js库的示例,您可以看到如何解决此问题.您需要实现一种jsonToStructProto方法来将JavaScript对象转换为proto结构,或者只是复制样本中的structjson.js文件.下面是一个使用该structjson.js文件的完整工作示例:

// Imports the Dialogflow library
const dialogflow = require('dialogflow');

// Import the JSON to gRPC struct converter
const structjson = require('./structjson.js');

// Instantiates a sessison client
const sessionClient = new dialogflow.SessionsClient();

// The path to identify the agent that owns the created intent.
const sessionPath = sessionClient.sessionPath(projectId, sessionId);

// The text query request.
const request = {
  session: sessionPath,
  queryInput: {
    event: {
      name: eventName,
      parameters: structjson.jsonToStructProto({foo: 'bar'}),
      languageCode: languageCode,
    },
  },
};

sessionClient
  .detectIntent(request)
  .then(responses => {
    console.log('Detected intent');
    logQueryResult(sessionClient, responses[0].queryResult);
  })
  .catch(err => {
    console.error('ERROR:', err);
  });
