Wechaty should support Channel Messages #2467
Description
Intro
Channel is kinda like a special link url. In Wechat/Wecom eco, it specifies a video or a live show in a channel account. I'm not sure if other IM has similar messages.
Data Structure
In Wechat/Wecom eco, Channel is defined like this:
export interface ChannelPayload {
avatar: string,
coverUrl: string,
desc: string,
extras: string,
feedType: number,
nickname: string,
thumbUrl: string,
url: string,
/**
* The following two fields are required for Live Channel only.
*/
objectId?: string,
objectNonceId?: string,
}The keys and data types are not very clear in semantic. So in wechaty puppet we should put it this way.
export interface ChannelPayload {
avatar: string,
coverUrl: string,
description: string,
channelType: ChannelType,
nickname: string,
thumbUrl: string,
url: string,
liveId?: string,
liveNonceId?: string,
extras: string
}
export enum ChannelType {
Unknown = 0,
Photo = 2,
Video = 4,
Live = 9,
}Use in Wechaty
We use it just like miniProgram or urlLink.
e.g.: receiving a channel message
const channel = await message.toChannel()
const nickname = channel.nickname()
const type = channel.channelType()e.g.: sending a a channel message
const channel = new bot.Channel({
avatar: 'http://some.website.com/some/avata.png',
channelType: ChannelType.Video
...
})
await contact.say(channel)e.g.: posting a channel moment
const builder = bot.Post.builder()
const channel = new bot.Channel({ ... })
builder.add('This is a channel moment')
builder.type(Post.Moment)
builder.add(channel)
const post = await builder.build()
const publishedPost = bot.publish(post)
