node.js - 如何正确处理context.sendActivity？

Question

我只想问两个简单的问题，然后出示卡片。问题是，在第二个“sendActivity”中，永远重复“请提供密码”。我尝试在函数之后甚至内部放置另一个 onTurn，结果最差或相同。不想仅仅为了两个问题就实现整个 waterfall 。哪个 ActivityHandler 更适合我想要实现的目标？

async processLogin(context, next, res) {
        await context.sendActivity({
            text: 'please give username'
        })
        const SelectedCard2 = CARDS2[0];
        this.onTurn(async (context, next, res) => {
            let txt = `"${context.activity.text}"`;
            if (txt) {
                var name = JSON.parse(txt);
                console.log(name)
            }

       await context.sendActivity({
                text: 'please give password'
            })
            let txt2 = `"${context.activity.text}"`;
            if (txt2) {
                var password = JSON.parse(txt2);
                console.log(password)
                res = password;
            }

            await next();
            });
            }

enter link description here如果您只是想通过简单的方式从用户那里收集一些信息，您可以一步使用自适应卡，请尝试以下代码:

const { ActivityHandler,CardFactory } = require('botbuilder');


class EchoBot extends ActivityHandler {
    constructor() {
        super();
        // See https://aka.ms/about-bot-activity-message to learn more about the message and other activity types.

        var adaptiveCard = {
            "$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
            "type": "AdaptiveCard",
            "version": "1.0",

                        {
                            "type": "Column",
                            "width": 2,
                            "items": [

                                },
                                {
                                    "type": "Input.Text",
                                    "id": "username",
                                    "placeholder": "your user name here"
                                },
                                {

                                    "wrap": true
                                },
                                {
                                    "type": "Input.Text",
                                    "id": "password",
                                    "placeholder": "makre sure no one is around you ..."
                                }
                            ]
                        }
                    ]
                }
            ],
            "actions": [
                {
                    "type": "Action.Submit",
                    "title": "Submit"
                }
            ]
        };


        this.onMessage(async (context, next) => {

            if(context.activity.text==="login"){

                await context.sendActivity({ attachments: [CardFactory.adaptiveCard(adaptiveCard)] });

            }else if(context.activity.value != undefined){
                var user = context.activity.value;
                await context.sendActivity("hello , your username : " + user.username + ",password :" + user.password);

            }else {
                await context.sendActivity("send login to do test");
            }






            await next();
        });

        this.onMembersAdded(async (context, next) => {
            const membersAdded = context.activity.membersAdded;
            for (let cnt = 0; cnt < membersAdded.length; ++cnt) {
                if (membersAdded[cnt].id !== context.activity.recipient.id) {
                    await context.sendActivity('Hello and welcome!');
                }
            }
            // By calling next() you ensure that the next BotHandler is run.
            await next();
        });

    }
}





module.exports.EchoBot = EchoBot;

此代码基于官方nodejs echo bot，只需覆盖bot.js文件的内容即可测试:

希望有帮助。
