我需要我的Wit.ai聊天機器人來回復某些帶有圖片的信息,並且因爲我已經重構了我的代碼以匹配node-wit SDK中的最新信使示例我無法弄清楚如何去做。Wit.ai - 通過Facebook Messenger發送圖片發送API
此前該FB消息功能爲我工作:
var newMessage = function (recipientId, msg, atts, cb) {
var opts = {
form: {
recipient: {
id: recipientId
},
}
}
if (atts) {
var message = {
attachment: {
"type": "image",
"payload": {
"url": msg
}
}
}
} else {
var message = {
text: msg
}
}
opts.form.message = message
newRequest(opts, function (err, resp, data) {
if (cb) {
cb(err || data.error && data.error.message, data)
}
})
}
現在我已經更新到node-wit SDK messenger example:
const fbMessage = (id, text) => {
const body = JSON.stringify({
recipient: { id },
message: { text },
});
const qs = 'access_token=' + encodeURIComponent(FB_PAGE_TOKEN);
return fetch('https://graph.facebook.com/me/messages?' + qs, {
method: 'POST',
headers: {'Content-Type': 'application/json'},
body,
})
.then(rsp => rsp.json())
.then(json => {
if (json.error && json.error.message) {
throw new Error(json.error.message);
}
return json;
});
};
我已經修改這樣的嘗試,使圖像回覆工作:
const fbMessage = (id, text, atts) => {
if (atts) {
var body = {
attachment: {
"type": "image",
"payload": {
"url": { text }
}
},
};
} else {
var body = JSON.stringify({
recipient: { id },
message: { text },
});
}
const qs = 'access_token=' + encodeURIComponent(FB_PAGE_TOKEN);
return fetch('https://graph.facebook.com/me/messages?' + qs, {
method: 'POST',
headers: {'Content-Type': 'application/json'},
body,
})
.then(rsp => rsp.json())
.then(json => {
if (json.error && json.error.message) {
throw new Error(json.error.message);
}
return json;
});
};
短信正在正常發送,但當我嘗試se nd圖像附件,我的圖像url引用只是作爲字符串發送。
