I am using Aws Lex for constructing chatbots. I had a scenario where I need to have welcome message initially without user input so that I can give a direction to the user in my chatbot.

推荐答案

您需要使用API​​调用来处理该方案，以与您的用户启动上下文.

You need to work that scenario using API call to start a context with your user.

您可以按照以下步骤操作:

• 您需要创建一个名为AutoWelcomeMessage的Intent.
• 创建一个仅包含一个值的Slot type，即:HelloMe.
• 创建话语HelloMessage.
• 创建Slot如下:必填，名称:answer，插槽类型:HelloMe，提示:'AutoWelcomePrompt'.
• 为您的Fulfillment选择Amazon Lambda，它将发送响应给您的用户.即:

• You need to create an Intent called AutoWelcomeMessage.
• Create a Slot type with only one value i.e: HelloMe.
• Create an Utterances HelloMessage.
• Create a Slot as follow: Required, name: answer, Slot Type: HelloMe, Prompt: 'AutoWelcomePrompt'.
• Pick Amazon Lambda for your Fulfillment that will send a response to your user. I.e:

您好，我可以帮您吗? (该用户将在此处输入另一个Intent，您的Bot会回复).

Hello user, may I help? (Here the user will enter another Intent and your Bot will respond).

现在，与您的用户开始对话，只需通过API调用Lex Bot并发送带有Intent AutoWelcomeMessage的意图，该调用将启动与Lex Bot的上下文，而fulfillment将执行您的Lambda.

Now, start a conversation with your User, just call via API your Lex Bot and send an intention with Intent AutoWelcomeMessage, that call starts a context with your Lex Bot and the fulfillment will execute your Lambda.
