Botframework 如何在node.js中获取Microsoft azure bot sdk 4.0中的会话对象？

附加下面的代码段。botbuilder 4.1.5中不推荐使用UniversalBot和ChatConnector

var bot;
try {
    bot = new BasicBot(conversationState, userState, botConfig);
} catch (err) {
    console.error(`[botInitializationError]: ${ err }`);
    process.exit();
}

// Create HTTP server
// let server = restify.createServer();
let server = express();
server.listen(process.env.port || process.env.PORT || 3978, function() {
    console.log(`\n${ server.name } listening to ${ server.url }`);
    console.log(`\nGet Bot Framework Emulator: https://aka.ms/botframework-emulator`);
    console.log(`\nTo talk to your bot, open basic-bot.bot file in the Emulator`);
});

// Listen for incoming activities and route them to your bot main dialog.
server.post('/api/messages', (req, res) => {
    // Route received a request to adapter for processing
    adapter.processActivity(req, res, async (turnContext) => {
        // route to bot activity handler.
        await bot.onTurn(turnContext);
    });
});

你的问题相当笼统

已删除3.x中的会话对象。而是使用访问器。您将希望在bot类中执行以下操作：

    public onTurn = async (turnContext: TurnContext) => {
        const userProfile = await this.userProfile.get(turnContext, new UserProfile());
        const conversationData = await this.dialogStateAccessor.get(turnContext, { dialogStack: undefined });

        // set vars in cache
        userProfile.yourUserVarProp = "userValue";
        conversationData.yourConversationVarProp = "conversationValue";

        // persist userVars through dialog turn
        await this.userProfile.set(turnContext, userProfile);

        // persist conversationVars through dialog turn
        await this.dialogStateAccessor.set(turnContext, conversationData);


        //
        // -> your dialogs here (await dc.beginDialog("dialogname");)
        //


        // save uservars to db at end of a turn
        await this.userState.saveChanges(turnContext);
        // save conversationVars to db at end of a turn
        await this.conversationState.saveChanges(turnContext);
    }

但是还有一些额外的构造函数

• @param{ConversationState}ConversationState用于存储对话框状态的ConversationState对象
• @param{UserState}UserState用于存储特定于用户的值的UserState对象

。。。以及创建userProfile和dialogStateAccessor本身

对于整个画面，请仔细看一看

或者尝试生成器：
