我使用 bot 框架 v4 c# 在本地创建了一个机器人。它有一张欢迎卡，当我将本地 url 连接到模拟器时，它会自动弹出，但最近我在 azure 上部署了我的机器人，并使用直接线路 channel 将其集成到我的网站中。现在，每当我单击时，它都会打开机器人，但欢迎卡不会自行出现，当我从聊天机器人中写一些东西时，它就会出现。我只希望欢迎卡在模拟器中自动出现。伙计们，你能帮我一下吗？下面是我在我的网站中集成的直线代码。

document.getElementsByTagName('body')[0].appendChild(div);
div.outerHTML = "<div id='botDiv' style='width: 400px; height: 0px; margin:10px; position:

BotChat.App({
botConnection: botConnection,
user: user,
bot: bot
}, document.getElementById("botDiv"));
document.getElementsByClassName("wc-header")[0].setAttribute("id", "chatbotheader");
document.querySelector('body').addEventListener('click', function (e) {
e.target.matches = e.target.matches || e.target.msMatchesSelector;
if (e.target.matches('#chatbotheader')) {
var botDiv = document.querySelector('#botDiv');
botDiv.style.height = "0px";
document.getElementById("mychat").style.display = "block";
};
});
document.getElementById("mychat").addEventListener("click", function (e) {
document.getElementById("botDiv").style.height = '500px';
e.target.style.display = "none";
})
}());
</script>
这也是我用 c# 编写的欢迎卡代码
namespace Microsoft.BotBuilderSamples
{
public class WelcomeUser : SaathiDialogBot<MainDialog>
{
protected readonly string[] _cards =
{
Path.Combine(".", "Resources", "WelcomeCard.json"),
};
public WelcomeUser(ConversationState conversationState, UserState userState, MainDialog dialog, ILogger<SaathiDialogBot<MainDialog>> logger)
: base(conversationState, userState, dialog, logger)
{
}
protected override async Task OnMembersAddedAsync(IList<ChannelAccount> membersAdded, ITurnContext<IConversationUpdateActivity> turnContext, CancellationToken cancellationToken)
{
await SendWelcomeMessageAsync(turnContext, cancellationToken);
Random r = new Random();
var cardAttachment = CreateAdaptiveCardAttachment(_cards[r.Next(_cards.Length)]);
await turnContext.SendActivityAsync(MessageFactory.Attachment(cardAttachment), cancellationToken);
}
private static async Task SendWelcomeMessageAsync(ITurnContext turnContext, CancellationToken cancellationToken)
{
foreach (var member in turnContext.Activity.MembersAdded)
{
if (member.Id != turnContext.Activity.Recipient.Id)
{
if (DateTime.Now.Hour < 12)
{
await turnContext.SendActivityAsync(
$"Hi,Good Morning {member.Name}",
cancellationToken: cancellationToken);
}
else if (DateTime.Now.Hour < 17)
{
await turnContext.SendActivityAsync(
$"Hi,Good Afternoon {member.Name}",
cancellationToken: cancellationToken);
}
else
{
await turnContext.SendActivityAsync(
$"Hi,Good Evening {member.Name}",
cancellationToken: cancellationToken);
}
}
}
}
private static Attachment CreateAdaptiveCardAttachment(string filePath)
{
var adaptiveCardJson = File.ReadAllText(filePath);
var adaptiveCardAttachment = new Attachment()
{
ContentType = "application/vnd.microsoft.card.adaptive",
Content = JsonConvert.DeserializeObject(adaptiveCardJson),
};
return adaptiveCardAttachment;
}
}
}
这里是欢迎卡中继承的saathiDialog代码。这是我的 bot 文件夹中的两个文件
namespace Microsoft.BotBuilderSamples
{
public class SaathiDialogBot<T> : ActivityHandler where T : Dialog
{
protected readonly BotState ConversationState;
protected readonly Dialog Dialog;
protected readonly ILogger Logger;
protected readonly BotState UserState;
private DialogSet Dialogs { get; set; }
public SaathiDialogBot(ConversationState conversationState, UserState userState, T dialog, ILogger<SaathiDialogBot<T>> logger)
{
ConversationState = conversationState;
UserState = userState;
Dialog = dialog;
Logger = logger;
}
public override async Task OnTurnAsync(ITurnContext turnContext, CancellationToken cancellationToken = default(CancellationToken))
{
var activity = turnContext.Activity;
if (string.IsNullOrWhiteSpace(activity.Text) && activity.Value != null)
{
activity.Text = JsonConvert.SerializeObject(activity.Value);
}
if (turnContext.Activity.Text == "Yes")
{
await turnContext.SendActivityAsync($"Good bye. I will be here if you need me. ", cancellationToken: cancellationToken);
await turnContext.SendActivityAsync($"Say Hi to wake me up.", cancellationToken: cancellationToken);
}
else
{
await base.OnTurnAsync(turnContext, cancellationToken);
}
await ConversationState.SaveChangesAsync(turnContext, false, cancellationToken);
await UserState.SaveChangesAsync(turnContext, false, cancellationToken);
}
protected override async Task OnMessageActivityAsync(ITurnContext<IMessageActivity> turnContext, CancellationToken cancellationToken)
{
Logger.LogInformation("Running dialog with Message Activity.");
await Dialog.RunAsync(turnContext, ConversationState.CreateProperty<DialogState>(nameof(DialogState)), cancellationToken);
}
}
}
最佳答案
If you are using WebChat or directline, the bot’s ConversationUpdate is sent when the conversation is created and the user sides’ ConversationUpdate is sent when they first send a message. When ConversationUpdate is initially sent, there isn’t enough information in the message to construct the dialog stack. The reason that this appears to work in the emulator, is that the emulator simulates a sort of pseudo DirectLine, but both conversationUpdates are resolved at the same time in the emulator, and this is not the case for how the actual service performs.
解决方法是在建立 DirectLine 连接时向机器人发送反向 channel 欢迎事件，并从 onEventAsync 处理程序而不是 onMembersAdded 发送欢迎消息。

希望这有帮助。
