如何用 wit.ai 中的图片回复?
How to answer back with images in wit.ai?
我正在尝试使用 wit.ai.In wit.ai 创建一个 fb_messenger 机器人,我只能回答和提问 text.But 我想回答用户通过显示 images.How 来做到这一点?请指导我。
非常感谢。
您需要使用图片附件模板。
curl -X POST -H "Content-Type: application/json" -d '{
"recipient":{
"id":"<USER_ID>"
},
"message":{
"attachment":{
"type":"image",
"payload":{
"url":"<IMAGE_URL>"
}
}
}
}' "https://graph.facebook.com/v2.6/me/messages?access_token=<PAGE_ACCESS_TOKEN>"

您需要使用 Messenger Bot 在您的 Wit 操作中发送图片:
使用 Node js 的示例:
const actions = {
/**
* This is used by the "Bot sends" action in Wit
* @param sessionId
* @param text
* @returns {Promise.<T>}
*/
send({sessionId}, {text}) {
// Our bot has something to say!
// Let's retrieve the Facebook user whose session belongs to
const recipientId = sessions[sessionId].fbid;
if (recipientId) {
// Yay, we found our recipient!
// Let's forward our bot response to her.
// We return a promise to let our bot know when we're done sending
//bot is a simple wrapper for Messenger node code provided [here][1]
return bot.sendTextMessage(recipientId, text)
.catch((err) => {
console.error(
'Oops! An error occurred while forwarding the response to',
recipientId,
':',
err.stack || err
);
});
} else {
console.error('Oops! Couldn\'t find user for session:', sessionId);
// Giving the wheel back to our bot
return Promise.resolve()
}
},
['my-custom-action']({sessionId, context, entities, message}) {
//Api calls ...
//now i got an image URL i want to send to the user
return bot.sendImageMessage(recipientId, image_url);
return Promise.resolve(context)
},
不要忘记从您在 Wit.ai 上的故事中删除 "Bot sends" 部分,这样您就不会同时发送图片和 URL。
希望对您有所帮助!
