使用仿真器进行测试时,程序不会等待用户在上下文中输入内容,也不会等待将对话框转发到另一个对话框时
连接新用户时,我的MessagesController会打招呼:
if(activity.Type == ActivityTypes.ConversationUpdate)
{
if (activity.MembersAdded.Count == 1)
{
await Conversation.SendAsync(activity, () => new Dialogs.GreetDialog());
}
}
然后我的“问候”对话框输出“ Hello”,并转发到GatherUserDialog:
public async Task StartAsync(IDialogContext context)
{
context.UserData.Clear();
context.Wait(GatherInfoAsync);
}
private async Task GatherInfoAsync(IDialogContext context, IAwaitable<object> args)
{
var activity = await args as Activity;
if (!(context.UserData.ContainsKey("askedname")))
{
await context.PostAsync("Hello!");
await context.Forward(new GatherUserDialog(), this.MessageReceivedAsync, activity);
}
}
我的GatherUserDialog应该提示用户输入用户名,然后连接到数据库并使用该用户名获取用户:
Object person;
public async Task StartAsync(IDialogContext context)
{
await context.PostAsync("May I please have your username?");
context.UserData.SetValue("askedname", true);
context.Wait(MessageReceivedAsync);
}
private async Task MessageReceivedAsync(IDialogContext context, IAwaitable<object> result)
{
var activity = await result as Activity;
await result;
using (SoCoDirectoryModel model = new SoCoDirectoryModel())
{
var ents = model.Entities;
var text = activity.Text;
this.person = (from e in model.Entities
where e.EmployeeId == activity.Text
select e).SingleOrDefault();
}
if (this.person == null)
{
await context.PostAsync("Could not find that user. Please try again.");
context.Wait(MessageReceivedAsync);
}
else
{
this.person = person as Ent;
await context.PostAsync($"Hello {(this.person as Ent).FirstName}, what can I do for you?");
context.Wait(MessageReceivedAsync);
}
context.Wait(MessageReceivedAsync);
}
```
我不确定在这里放什么,除了上面的代码并更新NuGet软件包以使用最新的稳定版本的软件包之外,我没有做任何其他特别的事情。
预期的行为应该是问候语,然后提示输入用户名,然后传递该用户名以获取帐户信息。
似乎模拟器在启动时会发送2条帖子, state.getConversationData和state.getPrivateConversationData会同时运行,并在机器人应保留输入内容的所有等待中继续运行。到达GatherUserDialog后,该程序无法停止供用户输入,并尝试使用空字符串输入linq代码。 我相信这会导致超时异常,“抱歉,我的机器人代码有问题。”

这是一个已知问题。当bot连接到对话时,以及当用户连接到对话时,Direct Line连接器都会发送ConversationUpdate。当直线连接器发送ConversationUpdate时,它不会发送正确的User.Id,因此该漫游器无法构造对话框堆栈。模拟器的行为有所不同(它立即发送bot和用户ConversationUpdate事件,并且确实发送了正确的user.id。)
一种解决方法是不使用ConversationUpdate,而是从客户端发送事件,然后通过对话框响应该事件。
客户端javascript:
var user = {
id: 'user-id',
name: 'user name'
};
var botConnection = new BotChat.DirectLine({
token: '[DirectLineSecretHere]',
user: user
});
BotChat.App({
user: user,
botConnection: botConnection,
bot: { id: 'bot-id', name: 'bot name' },
resize: 'detect'
}, document.getElementById("bot"));
botConnection
.postActivity({
from: user,
name: 'requestWelcomeDialog',
type: 'event',
value: ''
})
.subscribe(function (id) {
console.log('"trigger requestWelcomeDialog" sent');
});
响应事件:
if (activity.Type == ActivityTypes.Event)
{
var eventActivity = activity.AsEventActivity();
if (eventActivity.Name == "requestWelcomeDialog")
{
await Conversation.SendAsync(activity, () => new Dialogs.GreetDialog());
}
}
