形式和意圖在Bot框架，wit.ai

Question

我有一個問題：我的機器人不遵循形式，它只是繼續威脅下一個答案的意圖。

http://g.recordit.co/GultDCEndR.gif

當我鍵入的第一條消息「порахуй」，它啓動我的形式Exams.BuildForm，但接下來我的回答使留下的形式，因爲其目的是不同的，因爲我得到了它。

我期望得到什麼：在我定義的意圖機器人開始形式，並不斷詢問問題，直到他們回答。

它在「порахуйконкурснийбал」案件上發佈表格。當消息的意圖與案例不匹配時留下。它預期的行爲？如果是這樣，我應該如何更改我的代碼以使表單提問，直到所有代碼都不會被回答？

我認爲這個問題是由於你怎麼有代碼。一旦你檢測到啓動表單的意圖，你不應該處理任何其他意圖（意思是你不應該允許通過其他開關/情況語句）。表單開始後的後續消息應該是await Conversation.SendAsync(activity, MakeRoot)，這樣才能正常工作。

我的建議是重新做你的邏輯。首先，你需要一個根對話框，你的大部分邏輯應該駐留在那裏;把它放在控制器上並不是一個很好的做法。一旦你這樣做了，你可以等待Conversation.SendAsync(activity,() => YourDialog)和對話框的MessageReceived，你可以調用wit.ai，處理意圖，啓動表單等。

我認爲做這些更改可能就足夠了。
