Question

我从dialogflow demo那里获得了参考。我收到

错误

';'预期。

在方法sendTextMessageToDialogFlow中

。我该如何解决这个问题？

这是我的代码

router.post('/dialogflow', function(req, res) {
  const projectId = "xxxxxxxxx";

  const LANGUAGE_CODE = 'en-US';
  let credentials = {
    private_key: xxxxxxxxx,
    client_email: "xxxxxxx",
  }
  let sessionClient = new dialogflow.SessionsClient(credentials);
  async sendTextMessageToDialogFlow(req.body.query, req.body.id) {
    const sessionPath = this.sessionClient.sessionPath(projectId, req.body.id);
    const request = {
      session: sessionPath,
      queryInput: {
        text: {
          text: req.body.query,
          languageCode: LANGUAGE_CODE
        }
      }
    }
    try {
      let responses = await this.sessionClient.detectIntent(request)
      console.log('DialogFlow.sendTextMessageToDialogFlow: Detected intent');
      res.json(responses);
    } catch (err) {
      console.error('DialogFlow.sendTextMessageToDialogFlow ERROR:', err);
      cosole.log(err);
    }
  }
})

您似乎缺少了function一词，并且function params中包含句点应该更像：

let sessionClient = new dialogflow.SessionsClient(credentials);
  async function sendTextMessageToDialogFlow(reqBodyQuery, reqBodyId) {
    const sessionPath = this.sessionClient.sessionPath(projectId, reqBodyId);
    const request = {
            session: sessionPath,
            queryInput: {
                text: {
                    text: reqBodyQuery,
                    languageCode: LANGUAGE_CODE
                }
            }
    }
    try {
            let responses = await this.sessionClient.detectIntent(request)          
            console.log('DialogFlow.sendTextMessageToDialogFlow: Detected intent');
            res.json(responses); 
        }
        catch(err) {
            console.error('DialogFlow.sendTextMessageToDialogFlow ERROR:', err);
            cosole.log(err);
        }
  }
})

不能将对象属性用于函数的参数。首先声明“ query”和“ id”变量，然后可以在函数中使用它们，因为它们在同一范围内。另外，您也缺少function关键字。

router.post('/dialogflow', function(req, res) {
  const projectId = "xxxxxxxxx";

  const LANGUAGE_CODE = 'en-US';
  let credentials = {
    private_key: xxxxxxxxx,
    client_email: "xxxxxxx",
  }
  let sessionClient = new dialogflow.SessionsClient(credentials);
  let query = req.body.query;
  let id = req.body.id;

  async function sendTextMessageToDialogFlow() {
    const sessionPath = this.sessionClient.sessionPath(projectId, id);
    const request = {
      session: sessionPath,
      queryInput: {
        text: {
          text: query,
          languageCode: LANGUAGE_CODE
        }
      }
    }
    try {
      let responses = await this.sessionClient.detectIntent(request)
      console.log('DialogFlow.sendTextMessageToDialogFlow: Detected intent');
      res.json(responses);
    } catch (err) {
      console.error('DialogFlow.sendTextMessageToDialogFlow ERROR:', err);
      cosole.log(err);
    }
  }
});
