如何处理DIRECT_LINE / POST_ACTIVITY_REJECTED

问题描述

我正在基于令牌以及聊天持久性来实现网络聊天，当用户在线时一切正常，但是经过一段时间的空闲后，如果用户离线且没有互联网连接，则大约需要30-45分钟，然后他又恢复在线并每当他发短信给机器人时，他都会声明 DIRECT_LINE / POST_ACTIVITY_REJECTED 并且用户无法与漫游器聊天，它会在我的消息提示框上放弃发送重试。有什么办法可以处理？。

 (async function() {
    'use strict';
    const {
            hooks: { usePostActivity },hooks: { useDirection },ReactWebChat
    } = window.WebChat;
    
     let { token,conversation_Id } = sessionStorage;
    if ( !token ) {
                    const res = await fetch( 'https:/localhost/api/generateToken',{ method: 'POST' } );
                    const { token: directLineToken,conversationId: conversationId } = await res.json();
                    sessionStorage[ 'token' ] = directLineToken;
                    sessionStorage[ 'conversation_Id' ] = conversationId;
                    token = directLineToken;
                    conversation_Id = conversationId;
                    }
                    
    if (token) {
        await setInterval(async () => {
        var myHeaders = new Headers();
        myHeaders.append("Authorization","Bearer "+ sessionStorage[ 'token' ]);
        let res = await fetch( 'https://directline.botframework.com/v3/directline/tokens/refresh',{
                                method: 'POST',headers: myHeaders,});
        const { token: directLineToken,conversationId } = await res.json();
            sessionStorage[ 'token' ] = directLineToken;
            sessionStorage[ 'conversation_Id' ] = conversationId;
            token = directLineToken;
            conversation_Id = conversationId;
        },1000*60*15)}
        
                        
    
    
    const  store = window.WebChat.createStore({},({ dispatch }) => next => action => {
    if(action.payload && action.payload.directLine) {
        const subscription = action.payload.directLine.connectionStatus$.subscribe({
                error: error => console.log( error ),next: value => {
                        if ( value === 0 ) {console.log('Uninitialized')} 
                        else if ( value === 1 ) {console.log('Connecting')} 
                        else if ( value === 2 ) {console.log('Online')}
                        else if  ( value === 3 ) {console.log('Expire Token')}
                        else if ( value === 4 ) {console.log('FailedToConnect')}
                        else if ( value === 5 ) {console.log('Ended')}
                }
            });
        }
     if (action.type === 'DIRECT_LINE/CONNECT_FULFILLED') {
        dispatch({
                type: 'WEB_CHAT/SEND_EVENT',payload: {
                    name: 'Welcome',value: { language: window.navigator.language }
                    }
                });
            }
            
    
    if (action.type === 'DIRECT_LINE/POST_ACTIVITY') {
                action = window.simpleUpdateIn(action,['payload','activity','channelData','CustomChannel'],() =>"webchat");
                }
    
        return next(action);
    });
    
    
   const  botconnection = createDirectLine( {token,webSockets: true,watermark: "0" });
    
    window.ReactDOM.render(
    <ReactWebChat directLine={botconnection}
                  store={store}
        />,document.getElementById('webchat'));
        document.querySelector('#webchat > *').focus();
        })().catch(err => console.error(err));

注意：令牌未过期，如果刷新，则漫游器开始响应。
