artificial-intelligence - 重铸.ai : TypeError: Cannot read property 'attachment' of undefined

Question

我希望我的 recast.bot 回复用户的回复。这是代码，但我收到以下错误消息。如何解决这个问题？

Bot Server is running on port 5002
TypeError: Cannot read property 'attachment' of undefined
    at new Message (C:\FD\Node\node_modules\recastai\lib\apis\resources\message.js:66:31)

我正在关注他们的 SDK: https://github.com/RecastAI/SDK-NodeJS/wiki/Receive-and-send-messages

    const express = require('express');
    const bodyParser = require('body-parser');
    const recastai = require('recastai').default;
    const build = new recastai.build('xxxxxx', 'en');

    var client = new recastai('xxxxxx')

    const app = express();
    const port = 5002;
    app.use(bodyParser.json());

   app.post('/', function(req, res) {
       client.connect.handleMessage(req, res, onMessage)
    })
    app.listen(port, () => {
        console.log('Bot Server is running on port ' + port);
    })  

    function onMessage (message) {
      var content = message.content    
      var type = message.type    
      message.addReply([{ type: 'text', content: 'Hello, world' }])
      message.reply()
        .then(res => console.log('message sent'))
    }

在 handlemessage 函数中，您正在使用获取消息有效负载中不存在的 .attachment 属性。使用新的构建器，您可以直接在构建器中管理这些消息，而无需事先构建后端
