用户配置文件状态在WebChat上为空,但在Directline和Emulator上为空

botframework c#

我正在通过 StateBot访问器 我的多对话机器人。我注意到在 网络聊天 ,通过_statebotaccessor.userprofileaccessor.getasync()检索用户配置文件时返回空值,但会话数据被持久化。通过Emulator和Directline进行的测试显示了正确填充的用户配置文件。

I created a git project built from EnterpriseBot template to show the problem.

下面是我的简单用户配置文件类:

public class UserProfile
{
    public UserProfile(string name)
    {
        this.UserName = name;
    }

    public string UserName { get; set; }
}

下面是我的SimpleConversationData类:

public class ConversationData
{
    public ConversationData(string channelId)
    {
        ChannelId = channelId;
    }

    // The ID of the user's channel.
    public string ChannelId { get; set; }
}

这是我的statebotaccessor类:

public class StateBotAccessors
{
    public StateBotAccessors(ConversationState conversationState, UserState userState)
    {
        ConversationState = conversationState ?? throw new ArgumentNullException("UserProfile");
        UserState = userState ?? throw new ArgumentNullException("ConversationData");
    }

    public IStatePropertyAccessor<UserProfile> UserProfileAccessor { get; set; }

    public IStatePropertyAccessor<ConversationData> ConversationDataAccessor { get; set; }

    public IStatePropertyAccessor<DialogState> DialogStateAccessor { get; set; }

    public ConversationState ConversationState { get; }

    public UserState UserState { get; }
}

在startup.cs上,我注册statebotaccessors。我在这里使用了InMemory存储,我用Blob存储进行了测试,但是结果是相同的。

        var dataStore = new MemoryStorage();
        var userState = new UserState(dataStore);
        var conversationState = new ConversationState(dataStore);

        services.AddSingleton(dataStore);

        var stateBotAccessors = new StateBotAccessors(conversationState, userState)
        {
            DialogStateAccessor = conversationState.CreateProperty<DialogState>("DialogState"),
            ConversationDataAccessor = conversationState.CreateProperty<ConversationData>("ConversationData"),
            UserProfileAccessor = userState.CreateProperty<UserProfile>("UserProfile"),
        };
        services.AddSingleton(stateBotAccessors);

在mainDialog.onStartAsync()上,我立即设置了用户配置文件和会话数据:

    protected override async Task OnStartAsync(DialogContext dc, CancellationToken cancellationToken = default(CancellationToken))
    {
        var context = dc.Context;

        // set userprofile and conversationdata
        await _accessors.ConversationDataAccessor.SetAsync(context, new ConversationData(dc.Context.Activity.ChannelId));
        await _accessors.UserProfileAccessor.SetAsync(context, new UserProfile("Elena"));

        await dc.Context.SendActivityAsync($"ConversationData and UserProfile were set in MainDialog.OnStartAsync()");

        // easier testing, I have this as a convenience method
        var reply = context.Activity.CreateReply();
        reply.Text = "Say 'print out state' or click the button.";
        reply.SuggestedActions = new SuggestedActions()
        {
            Actions = new List<CardAction>()
                {
                    new CardAction(type: ActionTypes.ImBack, title: "Test State", value: "print out state"),
                }
        };
        await context.SendActivityAsync(reply);
    }

我调用seconddialog如果用户的文本输入是“打印输出状态”,那么我将打印出会话数据和用户配置文件的内容,但在WebChat客户端上,用户配置文件始终为空:

        var conversationState = await _accessors.ConversationDataAccessor.GetAsync(sc.Context, () => null);
        var userProfile = await _accessors.UserProfileAccessor.GetAsync(sc.Context, () => null);

        await sc.Context.SendActivityAsync($"conversationState.ChannelId: {conversationState?.ChannelId}");
        await sc.Context.SendActivityAsync($"userProfile.UserName: {userProfile?.UserName}");

测试结果如下:

示例WebChat和Directline客户机位于Git项目的/clients文件夹下。我的网络聊天客户端很简单:

    const res = await fetch('https://directline.botframework.com/v3/directline/conversations', 
        { 
            method: 'POST',
            headers: {
                "Authorization": "Bearer mySecretKey",            
            },
        });
    const { token } = await res.json();

    var dl = window.WebChat.createDirectLine({ token });
    window.WebChat.renderWebChat({
      directLine: dl,
      user : user,
    }, document.getElementById('webchat'));
    document.querySelector('#webchat > *').focus();

我希望用户配置文件像在Emulator和Directline频道上一样在网络聊天频道上保持不变。我有什么东西不见了吗?可能是对网络聊天频道的特殊处理?
