dialogflow-es - 如何使用 Dialogflow ES Fulfillment 触发向人类发送电子邮件

问题描述

我在我的编辑器中使用fulfillment 和nodemailer，并想向我的个人电子邮件地址发送一封电子邮件。当我尝试集成到 Dialogflow Messenger Beta 版时，我的聊天机器人无法理解响应。

我的输出：

User: "I would like to send an email to the support service."
Bot: "Sorry. I do not understand your question."

正确的输出：

 User: "I would like to send an email to the support service."
 Bot: "What is your name?"
 User: "Henry"
 Bot: "What is your email?"
 User: "henry65@gmail.com"
 Bot: "Thanks Henry. We will get back to you as soon as possible."

});

我对 Dialogflow 还是很陌生，所以我对 webhook 和履行不是那么精通。请帮我。

解决方案

实现用例的一种方法是激活默认回退意图并启用该意图的实现。但是，您必须确保在回退意图中收集电子邮件地址。

  • 在 Dialogflow 上，webhook 由默认回退触发，它提供问题和 sessionID，然后将其保存在数据库中。
  • 然后回退方法请求一个电子邮件地址。
  • 最后，用户提供一封电子邮件，intent 触发另一个 webhook，它使用电子邮件地址更新原始记录并将请求发送到收件箱。

为了避免这种麻烦，您可以将 Dialoglfow 与任何第三方平台集成，例如Kommunicate，并直接从仪表板发送电子邮件通知。当触发默认回退意图或将人工代理分配给对话时，将自动发送一封电子邮件。

PS：我为 Kommunicate 工作。
