Question

我正在Microsoft Bot Framework使用directLine频道。我的Bot是公司客户门户网站的一部分，我从中获取一些用户信息并使用BotState将其存储在stateClient中，如下所示

 public ActionResult Index()
        {
            var userId = ClaimsPrincipal.Current.FindFirst(ClaimTypes.NameIdentifier).Value;
            GetTokenViaBootStrap().Wait();

            var botCred = new MicrosoftAppCredentials(
              ConfigurationManager.AppSettings["MicrosoftAppId"],
              ConfigurationManager.AppSettings["MicrosoftAppPassword"]);
            var stateClient = new StateClient(botCred);
            BotState botState = new BotState(stateClient);
            BotData botData = new BotData(eTag: "*");
            botData.SetProperty<string>("UserName", result.UserInfo.GivenName + " " + result.UserInfo.FamilyName);
            botData.SetProperty<string>("Email", result.UserInfo.DisplayableId);
            botData.SetProperty<string>("GraphAccessToken", UserAccessToken);
            botData.SetProperty<string>("TokenExpiryTime", result.ExpiresOn.ToString());

            stateClient.BotState.SetUserDataAsync("directline", userId, botData).Wait();

            var UserData = new UserInformationModel
            {
                UserId = userId,
                UserName = result.UserInfo.GivenName + " " + result.UserInfo.FamilyName
            };
            return View(UserData);
        }

作为directLine频道，我在javascript中使用秘密连接我的机器人，如下所示：

  BotChat.App({
        bot: { id: 'my_bot_id', name: 'my_bot_id' },
        resize: 'detect',
        sendTyping: true,    // defaults to false. set to true to send 'typing' activities to bot (and other users) when user is typing
        user: { id: UserData.UserId},
        directLine: {
            secret: "my_bot_secret"
        }
    }, document.getElementById('my_bot_id'));

我正在访问MVC站点中捕获的Node js Bot中的用户信息数据，如下所示：

function sessionUserCapture(session) {

    switch (session.message.address.channelId) {
        case 'skypeforbusiness':
            // some code
            break;
        case 'directline':
               userName= session.userData.UserName;
               userEmail= session.userData.Email;
               //some code
            break;
        case 'slack':
        // some code
    }
}

我提到了微软的Save state data from Manage state data以获取上述代码，然后我使用userData中提供的session来访问我的Node.JS Bot中的此数据。

由于StateClient已弃用，我提及this以stateclient替换Azure Table storage。但是，我无法理解如何将上述数据存储在Table Storage中。

有人可以提出任何我可以参考解决此问题的文章吗？

我的机器人位于NodeJs，我在directLine使用C# MVC application频道。

一种选择是使用.NET的 Microsoft Azure存储客户端库，如下面的答案中所述：How to retrieve Saved Conversation Data in Azure (Tablelogger)只需确保遵循完全相同的PartitionKey策略通过TableBotDataStore类，并正确序列化数据字段。

- 编辑：我测试了这个，它确实按预期工作。

 public class WebChatController : Controller
{
    public ActionResult Index()
    {
        var connectionString = ConfigurationManager.ConnectionStrings["StorageConnectionString"].ConnectionString;
        CloudStorageAccount storageAccount = CloudStorageAccount.Parse(connectionString);

        CloudTableClient tableClient = storageAccount.CreateCloudTableClient();

        CloudTable table = tableClient.GetTableReference("BotStore");
        string userId = Guid.NewGuid().ToString();
        TableQuery<BotDataRow> query = new TableQuery<BotDataRow>().Where(TableQuery.GenerateFilterCondition("PartitionKey", QueryComparisons.Equal, userId));

        var dataRow = table.ExecuteQuery(query).FirstOrDefault();
        if(dataRow != null)
        {
            dataRow.Data = Newtonsoft.Json.JsonConvert.SerializeObject(new
            {
                UserName = "This user's name",
                Email = "whatever@email.com",
                GraphAccessToken = "token",
                TokenExpiryTime = DateTime.Now.AddHours(1)
            });
            dataRow.Timestamp = DateTimeOffset.UtcNow;
            table.Execute(TableOperation.Replace(dataRow));
        }
        else
        {
            var row = new BotDataRow(userId, "userData");
            row.Data = Newtonsoft.Json.JsonConvert.SerializeObject(new
            {
                UserName = "This user's name",
                Email = "whatever@email.com",
                GraphAccessToken = "token",
                TokenExpiryTime = DateTime.Now.AddHours(1)
            });
            row.Timestamp = DateTimeOffset.UtcNow;
            table.Execute(TableOperation.Insert(row));
        }

        var vm = new WebChatModel();
        vm.UserId = userId;
        return View(vm);
    }

    public class BotDataRow : TableEntity
    {
        public BotDataRow(string partitionKey, string rowKey)
        {
            this.PartitionKey = partitionKey;
            this.RowKey = rowKey;
        }

        public BotDataRow() { }

        public bool IsCompressed { get; set; }
        public string Data { get; set; }
    }
}

在节点bot中：

'use strict';

const builder = require('botbuilder');
const restify = require('restify');
var azure = require('botbuilder-azure');

var tableName = 'BotStore';
var azureTableClient = new azure.AzureTableClient(tableName,'accountname','accountkey');
var tableStorage = new azure.AzureBotStorage({ gzipData: false }, azureTableClient);


const connector = new builder.ChatConnector({
    appId: process.env.MicrosoftAppId,
    appPassword: process.env.MicrosoftAppPassword
    });

const server = restify.createServer();
server.listen(process.env.port || process.env.PORT || 3979, () => {
    console.log(`${server.name} listening to ${server.url}`);
});

server.post('/api/messages', connector.listen());

var bot = new builder.UniversalBot(connector)
    .set('storage', tableStorage);;

bot.dialog('/',
[
    function (session){
        var data = session.userData;
    }
]);

您使用的代码使用的是已弃用的默认状态，但无效。为了实现您的目标，取决于您在代码中的位置。决定因素是您是否可以访问context对象。

例如，如果您在MessagesController，则无法访问上下文对象，您的代码可能如下所示：

public async Task<HttpResponseMessage> Post([FromBody]Activity activity)
            {
                if (activity.Type == ActivityTypes.Message)
                {

                    var message = activity as IMessageActivity;
                    using (var scope = DialogModule.BeginLifetimeScope(Conversation.Container, message))
                    {
                        var botDataStore = scope.Resolve<IBotDataStore<BotData>>();
                        var key = Address.FromActivity(message);

                        var userData = await botDataStore.LoadAsync(key, BotStoreType.BotUserData, CancellationToken.None);

                        userData.SetProperty("key 1", "value1");
                        userData.SetProperty("key 2", "value2");

                        await botDataStore.SaveAsync(key, BotStoreType.BotUserData, userData, CancellationToken.None);
                        await botDataStore.FlushAsync(key, CancellationToken.None);
                    }
                    await Conversation.SendAsync(activity, () => new Dialogs.RootDialog());
                }
            }

然后获取数据：

userData.GetProperty<string>("key 1");

另一种情况是，如果您确实可以像Dialog中那样访问上下文对象，那么您的代码可能如下所示：

        context.UserData.SetValue("key 1", "value1");
        context.UserData.SetValue("key 2", "value2");

然后获取数据：

context.UserData.GetValue<string>("key 1");

您是否已将机器人配置为连接到Global.asax.cs中的Azure表存储，而不是已弃用的默认状态？
我写了一篇博文，其中详细介绍了如何将机器人状态转移到Azure表存储，您应该查看 here

protected void Application_Start()
    {
        Conversation.UpdateContainer(
            builder =>
            {
                builder.RegisterModule(new AzureModule(Assembly.GetExecutingAssembly()));

                // Using Azure Table for storage
                var store = new TableBotDataStore(ConfigurationManager.ConnectionStrings["StorageConnectionString"].ConnectionString);

                builder.Register(c => store)
                    .Keyed<IBotDataStore<BotData>>(AzureModule.Key_DataStore)
                    .AsSelf()
                    .SingleInstance();
            });

        GlobalConfiguration.Configure(WebApiConfig.Register);
    }
