尝试整合 dialogflow 和 firebase答案

【问题描述】：

我正在尝试使用 Webhook 将 dialogflow 与 firebase 集成。我收到的回复是：

“网络钩子状态”：{ “代码”：13， "message": "Webhook 调用失败。错误：500 内部服务器错误。" }

Webhook 是：https://us-central1-miarduino-844c8.cloudfunctions.net/receiveAssistantRequests

Firebase 规则是：

{
  /* Visit https://firebase.google.com/docs/database/security to learn more about security rules. */
  "rules": {
    ".read": true,
    ".write": true
  }
}

我用过的index.js是：

const functions = require('firebase-functions');

// // Create and Deploy Your First Cloud Functions
// // https://firebase.google.com/docs/functions/write-firebase-functions
//
// exports.helloWorld = functions.https.onRequest((request, response) => {
//  response.send("Hello from Firebase!");
// });
const admin = require('firebase-admin');
admin.initializeApp();

const DialogflowApp = require('actions-on-google').DialogflowApp;

exports.receiveAssistantRequests = functions.https.onRequest((request, response) => {

    const app = new DialogflowApp({ request: request, response: response });

    function handlerRequest(app) {

        const device = app.getArgument('devices');
        const status = app.getArgument('status');

        return admin.database().ref(`/automation/${device}/value`).set(status)
            .then(snapshot => {
                app.ask(`Ok, switching ${device} ${status}. Do you want to control anything else?`);
            });

    }
    app.handleRequest(handlerRequest);
});

如果我使用soapUI 发出请求：https://us-central1-miarduino-844c8.cloudfunctions.net/receiveAssistantRequests 我明白了：

HTTP/1.1 500 Internal Server Error

Content-Type=text/plain; charset=utf-8

X-Content-Type-Options=nosniff

Server=Google Frontend

Content-Length=36

Alt-Svc=quic=":443"; ma=2592000; v="46,43,39"


Error: could not handle the request

有人知道如何解决这个问题吗？

不确定问题出在 Dialogflow 还是 Firebase 中

【问题讨论】：

这听起来你的代码有问题。您可以通过转到console.firebase.google.com，选择左侧的“功能”，然后在顶部导航中选择“日志”来查看调用时的错误日志。如果您使用错误日志的内容更新您的问题，我们可能会提供进一步的帮助。

【解决方案1】：

这可能会对你有所帮助。

const functions = require('firebase-functions');
    const admin = require('firebase-admin');
    admin.initializeApp({
      databaseURL: "YOUR_DATABASE_URL"});
    process.env.DEBUG = 'dialogflow:debug'; // enables lib debugging statements

    exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {
      const agent = new WebhookClient({request,response});
      console.log('dailog firebase admin'+agent);
      console.log('Dialogflow Request headers: ' + JSON.stringify(request.headers));
      console.log('Dialogflow Request body: ' + JSON.stringify(request.body));
      }
