的形式向用户发送消息

Postback received: {"payload":"Chatbots are fun! One day your BFF might be a Chatbot"}

如何更改它以便它只是以消息形式发送它？

Answer 1

Payload仅供您参考，以便当用户点击按钮时，您会在webhook中收到有效负载。然后您可以发回任何您想要的消息。例如，您可以将按钮设置为：

[{"type": "postback",
    "title": "What can Chatbots do",
    "payload": "payload_1",
    }, 
    {
    "type": "postback",
    "title": "The Future",
    "payload": "payload_2",
    }]

在您的webhook中，您可以使用以下方式发回消息：

if (event.postback) {
var text = JSON.stringify(event.postback.payload)

if(text === "\"payload_1\""){
    sendTextMessage(sender, "One day Chatbots will control the Internet of Things! You will be able to control your homes temperature with a text")
}
else if (text === "\"payload_2\""){
    sendTextMessage(sender, "Chatbots are fun! One day your BFF might be a Chatbot")
}
}
