Dialogflow是一种简单的授权方式

虽然没有很好的文档记录,但最简单的身份验证方法是使用谷歌云平台控制台上提供的JSON文件。

const sessionClient = new dialogflow.SessionsClient({
    keyFilename: '/path/to/google.json'
});
const sessionPath = sessionClient.sessionPath(projectId, sessionId);

这也适用于所有其他客户。 ContextsClients , EntityTypesClient 等等

我正在写代码,这对我很有用。请遵循中提供的所有步骤 Reference link 2 出于编码目的,您可以使用提供的代码段。

我还添加了Google Cloud Oauth的JSON示例

//
const projectId = 'mybot';

// generate session id (currently hard coded)
const sessionId = '981dbc33-7c54-5419-2cce-edf90efd2170';
const query = 'hello';
const languageCode = 'en-US';

// Instantiate a DialogFlow client.
const dialogflow = require('dialogflow');
let privateKey = 'YourKey';

// as per goolgle json
let clientEmail = "yourID@mybot.iam.gserviceaccount.com";
let config = {
  credentials: {
    private_key: privateKey,
    client_email: clientEmail
  }
}
const sessionClient = new dialogflow.SessionsClient(config);

// Define session path
const sessionPath = sessionClient.sessionPath(projectId, sessionId);

// The text query request.
const request = {
  session: sessionPath,
  queryInput: {
    text: {
      text: query,
      languageCode: languageCode,
    },
  },
};

// Send request and log result
sessionClient
  .detectIntent(request)
  .then(responses => {
    console.log('Detected intent');
    const result = responses[0].queryResult;
    console.log(`  Query: ${result.queryText}`);
    console.log(`  Response: ${result.fulfillmentText}`);
    if (result.intent) {
      console.log(`  Intent: ${result.intent.displayName}`);
    } else {
      console.log(`  No intent matched.`);
    }
  })
  .catch(err => {
    console.error('ERROR:', err);
  });

几个月前我也有同样的问题,看看这个,我就是这样解决的。 谷歌云从你的JSON中提取这行代码。

const dialogflow = require('dialogflow');
const LANGUAGE_CODE = 'en-US'
const projectId = 'projectid';
const sessionId = 'sessionId';
const query = 'text to check';


let privateKey = "private key JSON";
let clientEmail = "email acount from JSON";
let config = {
credentials: {
    private_key: privateKey,
    client_email: clientEmail
}
};

sessionClient = new dialogflow.SessionsClient(config);

async function sendTextMessageToDialogFlow(textMessage, sessionId) {
// Define session path
const sessionPath = this.sessionClient.sessionPath(projectId, sessionId);
// The text query request.
const request = {
    session: sessionPath,
    queryInput: {
        text: {
            text: textMessage,
            languageCode: LANGUAGE_CODE
        }
    }
}
try {
    let responses = await this.sessionClient.detectIntent(request)
    console.log('DialogFlow.sendTextMessageToDialogFlow: Detected intent', responses);
    return responses
} catch (err) {
    console.error('DialogFlow.sendTextMessageToDialogFlow ERROR:', err);
    throw err
}
};


sendTextMessageToDialogFlow(query, sessionId)

从最初的问题开始,Dialogflow身份验证的文档得到了改进。你应该在这里找到所有答案:

Authentication and access contro

我遵循上述解决方案,但没有什么变化:

// A unique identifier for the given session
const sessionId = uuid.v4();

// Create a new session

const sessionClient = new dialogflow.SessionsClient({
    keyFilename: require("path").join('config/google-credential.json')
});
const sessionPath = sessionClient.sessionPath(process.env.DIALOGFLOW_PROJECTID, sessionId);
