Question

下面是我的代码是为bot框架编写的，我参考了git hub中的文档，以及大量文章和堆栈溢出的帖子，似乎在WebChat行显示bot时抛出了错误。聊天，这也是stackoverlfow中的帖子中的link：

declare var require: any
var React = require('react');
var ReactDOM = require('react-dom');
var DirectLine  = require('botframework-directlinejs');
//import * as WebChat from 'botframework-webchat';
var WebChat = require('botframework-webchat');


export class Hello extends React.Component {
    constructor() {
        super();
        this.state = { data: [] };
        this.variableValue = { dataValue: [] };

    }
    async componentDidMount() {
        const response = await fetch('https://directline.botframework.com/v3/directline/tokens/generate', {
            method: 'POST',
            headers: {
                'Authorization': 'Bearer secretvalue',
                'Accept': 'application/json',
                'Content-Type': 'application/json',
            },
            body: JSON.stringify({
                accessLevel: 'View',
                allowSaveAs: 'false',
            })
        });
        // const { token } = await res.json();
        const { token } = await response.json();
        console.log(token);
        this.setState({ data: token });
        // 
    }
    render() {
        const {
            state: { data }
        } = this

        return (

            //<div>
            //    <p>Hello there1</p>
            //    <ul>
            //        {data}
            //    </ul>
            //</div>
            <WebChat.Chat
                directLine={{
                   data,
                    webSocket: false
                }}
                style={{
                    height: '100%',
                    width: '100%'
                }}
                //user={{
                //    id: 'default-user',
                //    name: 'Some User'
                //}}
            />



        );
    }

}

ReactDOM.render(<Hello />, document.getElementById('root'));

我能够通过Rest调用获取令牌，但是在使用WebChat.Chat directLine来显示机器人时出现错误错误如下：

编辑我能够使用react和babel在html文件中运行代码，下面是代码。...

        document.querySelector('#webchat > *').focus();
        })().catch(err => console.error(err));
    </script>
  </body>
</html>

但是当我在节点js应用程序中使用它时，在使用WebCHat.Chat时遇到了问题。

Web聊天有两个版本-v3和v4。您引用的StackOverflow问题是使用Web Chat v3，而您使用的依赖项是v4。请查看下面的代码片段，以了解带有Node的Web Chat v4实现的外观。

import React from 'react';

import ReactWebChat, { createDirectLine } from 'botframework-webchat';

export default class extends React.Component {
  constructor(props) {
    super(props);

    this.state = {
      directLine: null
    };
  }

  componentDidMount() {
    this.fetchToken();
  }

  async fetchToken() {
    const res = await fetch('https://webchat-mockbot.azurewebsites.net/directline/token', { method: 'POST' });
    const { token } = await res.json();

    this.setState(() => ({
      directLine: createDirectLine({ token })
    }));
  }

  render() {
    return (
      this.state.directLine ?
        <ReactWebChat
          className="chat"
          directLine={ this.state.directLine }
        />
      :
        <div>Connecting to bot&hellip;</div>
    );
  }
}
