Question

我正在使用Dialogflow构建聊天机器人，并且正在使用Axios进行发布并获取请求，但有时HTTP调用中的agent.add（）无法正常工作。

我附上示例代码。

const functions = require('firebase-functions');
const {WebhookClient} = require('dialogflow-fulfillment');
const {Card, Suggestion} = require('dialogflow-fulfillment');

// Using some external libraries
//axios for using third party api hosted as http.
const axios = require('axios');
// xml2js for parsing xml output in response
const xml2js = require('xml2js');

const json = require('json');

// Accessing firebase admin
const admin = require('firebase-admin');

function name(agent){


                    return axios.post('http://some-api,
                        {"name": "Kyle"}).then((result) => {

                            console.log('Store datato api');
                            agent.add('What is your email id'); // Sometimes its working and sometimes its not
                            //return Promise.resolve(agent); // I tried this as well but the same issue.


                    });


  }

可能是适当的更改，因为我在研究Stackoverflow上的所有其他问题时，我也尝试返回pomise，但没有用。

您似乎没有正确构造Promise。这是我用来返回需要承诺的响应的格式：

function name(agent) {
    const promise = new Promise(resolve => {

        // logic goes here

        resolve(agent.add(output));
    });
    return promise;
}

如果这不起作用，请检查其他地方是否可能失败-您确定您的网络挂钩在POST请求中没有失败吗？

agent.add（）有时无法在dialogflow中给出结果
