DingtalkBot API

Library supports DSL to build and sends DingtalkBot messages, driven by Vert.x and kotlinx.serialization.

Usage

You need a web hook and an optional signature (in robot settings) to create a DingtalkBot:

val bot = DingtalkBot(WEB_HOOK, SIGNATURE)

There are three ways to send messages:

• Async
• Blocking
• Suspend

Sending messages is implemented by kotlin coroutines.

Message Type

Overview

There are six types of messages:

• Text Message
• Markdown Message
• Link Message
• ActionCard Message
• FeedCard Message

Each of them has different data parameters and patterns in serialization.

Text Message

TextMessage is the simplest type of messages, which only contains a part of plain text.

Here is the way to build a TextMessage:

val at = at { 
	atMobiles = listOf("+86-13800138000","+86-12345678987")
	atAll = true
}

val message = textMessage("Hello, world.", at)

At is optional, and atMobiles includes people to be at. However, if atAll is true, dingtalk will ignore atMobiles.

Parameter	Optional	Default Value
text	No	-
at	Yes	null

Markdown Message

MarkdownMessag is a kind of advanced TextMessage. It has extra parameter —— title and its text supports markdown syntax.

Here is the way to build a MarkdownMessage:

val message = markdownMessage {
	title = "Hello, world"
	text = "# Hello, World"
	at = at{
		atMobiles = listOf("+86-13800138000","+86-12345678987")
		atAll = true
	}
}

Similarly,At is optional.

Parameter	Optional	Default Value
title	No	-
text	No	-
at	Yes	null

Link Message

LinkMessage is a kind of advanced TextMessage as well. It has title, messageUrl, pictureUrl further. Notice that the type of text is plain.

Here is the way to build a LinkMessage:

val message = linkMessage {
	title = "Welcome to MechDancer"
	text = "MechDancer is a robot competition team."
	pictureUrl = "https://github.com/MechDancer/mechdancer.github.io/blob/master/css/images/mechdancer2.png?raw=true"
	messageUrl = "http://mechdancer.org"
}

LinkMessage has a picture in its body, and it's optional.

Parameter	Optional	Default Value
title	No	-
text	No	-
messageUrl	No	-
pictureUrl	Yes	""

ActionCard Message

FeedCard Message
