移动到 v2 API 快速自托管

Question

我想在我的 dialogflow fullfilment 中使用 V2 API。但是当我自己托管 express 时，只有 v1 有效，为什么？

使用 firebase 函数，V1 和 V2 使用相同的代码。

我应用这个：https://developers.google.com/actions/reference/nodejs/lib-v1-migration,

欢迎意图错误：

有什么想法吗？

Answer 1

我发现了问题。这是 bodyparser 的错误配置。

这是我的代码：

import express from 'express';
import { SERVER_NAME, ENTRY_POINT, PORT } from './constants';
import { app } from './app/app';

export const server = express();

server.set('port', PORT);
server.set('trust proxy', 'loopback');
server.use(express.json({}));
server.post(ENTRY_POINT, app);
server.get('/', (req, res) => {
  res.send(SERVER_NAME);
});

刚刚使用 express.use() 而不是带有 express 4.16 的正文解析器。在我看来，它解决了这个问题。现在带有 dialogflow 的 V2 API 似乎有效。
