Question

我用MS Botframework v4实现了一个聊天机器人。我使用UserState和ConversationState，而我的MemoryStorage是来自Azure的BlobDB。

运行机器人时，我得到了两个UserState数据集，而只有一个ConversationState数据集。

在我的对话框中的某个时刻，Bot似乎“切换”到另一个UserState数据集，并且以前保存在旧集中的所有内容都不再可用。

这是在谈话的早期发生的。

这是我的onTurn。在这里，我是第一次访问UserState和ConversationState：

async onTurn(turnContext) {

        const dc = await this.dialogSet.createContext(turnContext);

        //await logMessageText(this.memoryStorage, turnContext, this.userState);

        // See https://aka.ms/about-bot-activity-message to learn more about the message and other activity types.
        if (turnContext.activity.type === ActivityTypes.value){
            console.log(turnContext.activity.type.value);
        }

        if (turnContext.activity.type === ActivityTypes.Message) {          
            // Continue ongoing dialog
            await dc.continueDialog();
        } else if (turnContext.activity.type === ActivityTypes.ConversationUpdate) {
            // Do we have any new members added to the conversation?
            if (turnContext.activity.membersAdded.length !== 0) {
                // Iterate over all new members added to the conversation
                for (var idx in turnContext.activity.membersAdded) {
                    // Greet anyone that was not the target (recipient) of this message.
                    // Since the bot is the recipient for events from the channel,
                    // context.activity.membersAdded === context.activity.recipient.Id indicates the
                    // bot was added to the conversation, and the opposite indicates this is a user.
                    if (turnContext.activity.membersAdded[idx].id !== turnContext.activity.recipient.id) {


                        // Funktionierender Code, wenn WebChat gefixt
                        console.log("User added");

                        // Read ConversationData from State
                        const conversationData = await this.conversationDataAccessor.get(turnContext, {});
                        const user = await this.userDataAccessor.get(turnContext, {});


                        // Get userID which is either IDA for advisory or IDR for result
                        conversationData.URLparam = turnContext.activity.membersAdded[idx].id;

                        // Manually set userId for Emulator use
                        conversationData.URLparam = "1234A";


                        // Set userID
                        if (!conversationData.userID) {
                            console.log("UserID wird eingetragen");
                            conversationData.userID = conversationData.URLparam.substring(0, conversationData.URLparam.length-1);
                            console.log("Eingetragene user ID:" + conversationData.userID);
                        }

                        // Get last character which determines mode
                        conversationData.mode = conversationData.URLparam.substring(conversationData.URLparam.length-1, conversationData.URLparam.length);

                        // Write user and conversationdata to State
                        await this.conversationDataAccessor.set(turnContext, conversationData);
                        await this.userDataAccessor.set(turnContext, user);


                        // Route to correct dialog depending on treatment and bot type
                        if (treatment.initiation == true && conversationData.mode.localeCompare("A") == 0) {
                            console.log("Advisory Modus");
                            await dc.beginDialog('welcome', conversationData.userID);
                        } else if (treatment.initiation == false) {
                            await dc.beginDialog('startBot', conversationData.userID);
                        } else if (treatment.initiation == true && conversationData.mode.localeCompare("R") == 0) {
                            console.log("Result Modus");
                            await dc.beginDialog('investmentResult', conversationData.userID)
                        }
                    }
                    if (turnContext.activity.membersAdded[idx].id === turnContext.activity.recipient.id) {
                        // Start the dialog.
                        console.log("Bot joined");

                    }
                }
            }
        }

首先调用我的对话框“ welcome”，然后调用“ promptForName”。在下一个代码段中一切正常：

// Function for welcoming user
    async welcomeUser (step) {
        console.log("Welcome User Dialog");

        // Get userId from onTurn()
        const userID = step.options;

        // Get conversation- and userData from bot state
        const conversationData = await this.conversationDataAccessor.get(step.context, {});
        const user = await this.userDataAccessor.get(step.context, {});


        console.log("User in welcome dialog");
        console.log(util.inspect(user, false, null, false ));

        console.log("conversationData from Middleware");
        console.log(util.inspect(conversationData, false, null, false ));


        // Write user and conversationdata to state
        await this.userDataAccessor.set(step.context, user);
        await this.conversationDataAccessor.set(step.context, conversationData);


        // Welcome the user
        if (treatment.introduction == true && treatment.rememberName == true && treatment.gender == true) {
            await sendWithDelay("Hallo und herzlich willkommen, ich bin **Charles**, dein persönlicher **Investmentberater**. Ich begleite dich durch den Beratungsprozess.", step);
        } else if (treatment.introduction == true && treatment.gender == false) {
            var msg = "Hallo und herzlich willkommen, ich bin ein **Robo-Advisor**. Ich begleite dich durch den Beratungsprozess.";
            await sendWithDelay(msg, step);
        } else if (treatment.introduction == false && treatment.selfReference == false && treatment.rememberName == false) {
            var msg = "Du wirst nun durch den Beratungsprozess begleitet.";
            await sendWithDelay(msg, step);
        }

        // Check if bot in testmode and route to dialogs
        if (testing == true) {
            // Start main dialog
            return await step.beginDialog('mainMenu', userID);
        } else {
            // Start Profilecreation
            return await step.beginDialog('createProfile', userID);
        }
    }

    // Functions for creating UserProfile 
        async promptForName (step) {
            console.log("Name Prompt");

            // Get userID from prior step and clear changes
            const userID = step.options;

            // Read UserData from State
            const user = await this.userDataAccessor.get(step.context, {});
            const conversationData = await this.conversationDataAccessor.get(step.context, {});

            // Save User- and Conversationdata to State
            await this.userDataAccessor.set(step.context, user);
            await this.conversationDataAccessor.set(step.context, conversationData);

            // Before prompting, check if value already exists
            if(!user.name){
                if (user.deleted == true) {

                        if (treatment.selfReference == true) {
                            var msg = "Ich stelle dir nun die gleichen Fragen erneut.";
                            await sendWithDelay(msg, step);
                        } else {
                            var msg = "Im folgenden nochmal die gleichen Fragen.";
                            await sendWithDelay(msg, step);
                        }
                } else {
                        if (treatment.selfReference == true) {
                            var msg = "Ich stelle dir nun ein paar Fragen, um deine wichtigsten Daten zu erfassen.";
                            await sendWithDelay(msg, step);
                        } else {
                            var msg = "Im folgenden ein paar Fragen, um deine wichtigsten Daten zu erfassen.";
                            await sendWithDelay(msg, step);
                        }

                }
                // Username doesn't exist --> Prompt
                await delay(userData.name.prompt, step).then(async function() { 
                    return await step.prompt(NAME_PROMPT, userData.name.prompt);
                });
            } else {
                return await step.next();
            }
        }

在下一个将用户的回复写入userData的代码段中，突然创建了一个新的dataSet。

async promptForAge (step) {
            console.log("Age Prompt");

            // Get userID from prior step and clear changes
            var userID = step.options;

            // Get UserData from State
            const user = await this.userDataAccessor.get(step.context, {});

            console.log("User in age dialog");
            console.log(util.inspect(user, false, null, false ));



            // Before saving entry, check if it already exists
            if(!user.name) {

                user.name = step.result;

                // Write userData to State
                await this.userDataAccessor.set(step.context, user);


                // Notify user about his name being remembered
                if (treatment.rememberName == true) {
                    var msg = `Hallo **${user.name}**! Danke, dass du mir deinen Namen verraten hast. Ich werde ihn mir ab jetzt merken.`;
                    await sendWithDelay(msg, step);
                }
            }
            // Before prompting, check if value already exists
            if(!user.age) {
                await delay(userData.age.prompt, step).then(async function() { 
                    return await step.prompt(AGE_PROMPT, userData.age.prompt);
                });

            } else {
                return await step.next();
            }
        }

这是数据库中数据集的外观：

这是两个用户数据集的内容：

正在创建的第一个

{"id":"emulator%2Fusers%2Fdeb871a4-cbb9-4e3c-9fff-e9ed88f597f5","realId":"emulator/users/deb871a4-cbb9-4e3c-9fff-e9ed88f597f5/","document":{"userData":{},"eTag":"*"}}

将step.result一次创建的内容写入user.name：

{"id":"emulator%2Fusers%2Fr_72zsnsmmnp","realId":"emulator/users/r_72zsnsmmnp/","document":{"userData":{"name":"John Doe"},"eTag":"*"}}

为什么UserState两次创建UserDataSet？
