百度UNIT 機器人多輪對話技能創建以及API調用

基於百度UNIT2.0 版本，實現簡單的多輪人機對話功能

創建機器人必備條件

確定有哪些技能
例如：查詢天氣、訂票、講故事等，以暢越冰激凌套餐營銷話術爲例
創建技能
確定技能包含的意圖
分析是任務型、閒聊型還是問答型。
任務型：將用戶意圖的關鍵詞參數化成詞槽，完成任務。例如訂票、退票、辦理業務等
問答型：有固定答案的對話，回答比較明確。例如業務諮詢，套餐查詢
閒聊型：沒有明確的意圖或者任務只是隨意聊天
分析營銷話術屬於任務型，以推銷套餐爲任務的意圖。
流程圖：
確定意圖包含的詞槽
詞槽：類似參數
爲詞槽添加詞典
注意如果詞槽之間詞典有重複的詞語，會出現意圖無法識別問題
爲意圖創建規則
例如：對話中必須出現詞槽中的詞纔會轉到意圖；一個意圖可以匹配多個規則
創建對話模板
不創建對話模板或者對話集，意圖無法生效
訓練模型
通過技能訓練將定義好的意圖訓練成模型，通過測試可以優化詞槽或者修改規則優化模型

調用API

調用技能前提需要創建應用，獲取API key 和Secret Key；使用兩個key值獲取調用api的token。

必備條件
- token, 獲取token需要API key 和Secret Key
- 調用Api地址
- 技能Id
調用實例
參考代碼地址
部分代碼。參考上述代碼，實現多輪對話調用：
獲取token

注意事項
如果需要調用多輪對話，需要將每次獲取到的結果中的bot_session 當做參數調用下一輪對話。
