下面是我为机器人框架编写的代码，我引用了 git hub 中的文档，并关注了很多文章和堆栈溢出的帖子，似乎在 WebChat 行显示机器人时抛出错误。聊天，这里是link也来自 stackoverlflow 中的帖子:
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'));
我可以通过休息调用获取 token ，但在必须使用 WebChat.Chat directLine 显示机器人时出现错误
以下是错误:

但是当我在 Node js 应用程序中使用它时，我在使用 WebCHat.Chat 时遇到了问题。
最佳答案
网络聊天有两个版本 - v3 和 v4。您提到的 StackOverflow 问题使用的是 Web Chat v3，而您使用的依赖项是 v4。请查看下面的代码片段，了解使用 Node 实现的 Web Chat v4 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…</div>
);
}
}
有关更多详细信息，请查看samples GitHub Repo 上的示例 17 是查看 Node 实现的一个很好的示例。
