Dialogflow中的自定义负载

Question

我尝试从履行(nodejs(在Dialogflow中发送自定义负载

我的动机是发送链接及其文本作为对网页的回应。

我的参考样本代码：

const response = {
messages: [
{
payload: {
messages: [
{
speech: 'here are some quick links for your convenience.',
linkmessage: [{
message: 'google',
link: 'www.google.com'
}, {
message: 'yahoo',
link: 'www.yahoo.co.in'
}],
button: [{
buttonname: 'more page'
}]
}
]
}
}
]
};
agent.add(new Payload(agent.UNSPECIFIED, response, { rawPayload: true, sendAsMessage: true}));

在这里我得到的回复是：

{
"fulfillment": {
"speech": "",
"messages": [
{
"lang": "en",
"type": 0,
"speech": ""
}
],
"data": {
"null": {
"messages": [
{
"payload": {
"messages": [
{
"speech": "here are some quick links for your convenience.",
"linkmessage": [{
"message": "google",
"link": "www.google.com"
}, {
"message": "yahoo",
"link": "www.yahoo.co.in"
}],
"button": [{
"buttonname": "more page"
}]
}
]
}
}
]
}
}
}

在这里，您可以看到在响应中，我得到的">null"对象被附加在响应中的数据对象内。

有谁能帮我从dialogflow响应中删除null对象，以及从履行nodejs发送自定义负载的任何其他选项吗。

Answer 1

function update() {
const response = {
messages: [
{
payload: {
messages: [
{
speech: 'here are some quick links for your convenience.',
linkmessage: [{
message: 'google',
link: 'www.google.com'
}, {
message: 'yahoo',
link: 'www.yahoo.co.in'
}],
button: [{
buttonname: 'more page'
}]
}
]
}
}
]
};
agent.add(new Payload(agent.UNSPECIFIED, response, { rawPayload: true, sendAsMessage: true}));
}

在这个函数中，需要添加参数作为代理，这样你就可以获得非"null"对象

参考代码需要更新。

function update(agent) {
const response = {
messages: [
{
payload: {
messages: [
{
speech: 'here are some quick links for your convenience.',
linkmessage: [{
message: 'google',
link: 'www.google.com'
}, {
message: 'yahoo',
link: 'www.yahoo.co.in'
}],
button: [{
buttonname: 'more page'
}]
}
]
}
}
]
};
agent.add(new Payload(agent.UNSPECIFIED, response, { rawPayload: true, sendAsMessage: true}));
}
