How to use dingtalk-message

  1. 1.Identify which messaging channel to use based on your scenario (Webhook, enterprise robot, work notification, or sessionWebhook)
  2. 2.Validate required configuration using `bash scripts/dt_helper.sh --get KEY`
  3. 3.Collect any missing credentials and store them with `bash scripts/dt_helper.sh --set KEY=VALUE`
  4. 4.Obtain access token using `--token` for robots or `--old-token` for work notifications (Webhook needs no token)
  5. 5.Execute the appropriate API call via curl with the correct endpoint and message format from references/api.md

dingtalk-message FAQ

What's the difference between Webhook robots and enterprise application robots?

Webhook robots are simplest for group notifications (URL includes credentials). Enterprise robots require app credentials but support single-chat, message recall, and read status queries.

How do I convert unionId to userId for messaging?

Use `bash scripts/dt_helper.sh --to-userid <unionId>` to convert unionId to the userId format required by message APIs.

Can I send messages to both individuals and groups with the same method?

No. For group messages, ask the user whether to use Webhook or enterprise robot. For single-chat, use enterprise robot messages. Work notifications can target individuals, departments, or the entire organization.

What should I do if a token request fails?

Try refreshing the token cache with `bash scripts/dt_helper.sh --token --nocache` or `bash scripts/dt_helper.sh --old-token --nocache`.

What message formats are supported?

Webhook supports text, Markdown, ActionCard, Link, and FeedCard. Enterprise robots and work notifications support text, Markdown, and other formats detailed in references/api.md.

name: dingtalk-message description: 钉钉消息发送。当用户提到"钉钉消息"、"发消息"、"发通知"、"群通知"、"群消息"、"Webhook"、"机器人消息"、"机器人发消息"、"工作通知"、"单聊消息"、"群聊消息"、"撤回消息"、"消息已读"、"发送Markdown"、"发卡片消息"、"ActionCard"、"@某人"、"@员工"、"at某人"、"提醒某人"、"dingtalk message"、"send message"、"robot message"、"work notification"时使用此技能。支持:群自定义 Webhook 机器人(文本/Markdown/ActionCard/Link/FeedCard + 加签 + @某人)、企业内部应用机器人单聊和群聊发送、消息撤回、已读查询、工作通知等全部消息类操作。

钉钉消息技能

负责钉钉消息发送的所有操作。本文件为策略指南;完整 API 请求格式、场景路由、消息类型速查、身份标识、错误码等见 references/api.md

dt_helper.sh 位于本 SKILL.md 同级目录的 scripts/dt_helper.sh

四种消息通道

通道适用场景Token特点
Webhook 机器人往指定群发通知无需最简单;URL 自带凭证
企业内部应用机器人单聊私信 / 群聊--token(新版)可撤回、查已读
工作通知应用推送到"工作通知"--old-token(旧版)可推全员/部门
sessionWebhook回调中直接回复无需回调消息自带临时 URL

工作流程(每次执行前)

  1. 识别通道 → 按 api.md「场景路由」判断属于哪个通道
  2. 校验配置bash scripts/dt_helper.sh --get KEY 读取该通道所需键值
  3. 收集缺失项 → 一次性询问并 bash scripts/dt_helper.sh --set KEY=VALUE 写入
  4. 获取 Token → 机器人用 --token;工作通知用 --old-token;Webhook/sessionWebhook 无需
  5. 执行 API → 多行逻辑写入 /tmp/<task>.sh 再执行;禁止 heredoc

各通道所需配置

通道所需配置来源说明
WebhookDINGTALK_WEBHOOK_URL(加签额外需 DINGTALK_WEBHOOK_SECRET群设置 → 智能群助手 → 添加自定义机器人
机器人消息DINGTALK_APP_KEY + DINGTALK_APP_SECRET开放平台 → 应用管理 → 凭证信息
工作通知DINGTALK_APP_KEY + DINGTALK_APP_SECRET + DINGTALK_AGENT_IDagentId 在应用管理 → 基本信息
  • robotCode = appKey(完全一致,无需额外配置)
  • 凭证禁止在输出中完整打印,确认时仅显示前 4 位 + ****
  • 消息内容缺失时:先询问用户想发什么,不要自行编造

身份标识

消息 API 只接受 userId(staffId),不接受 unionId。详见 grep -A 20 "^## 身份标识" references/api.md

  • unionId → userId 转换:bash scripts/dt_helper.sh --to-userid <unionId>
  • 群消息发送方式选择:发群消息时须先询问用户用 Webhook 还是企业机器人,详见 grep -A 20 "^### 群消息发送方式选择" references/api.md

执行脚本模板

#!/bin/bash
set -e
HELPER="./scripts/dt_helper.sh"
TOKEN=$(bash "$HELPER" --token)
USER_ID=$(bash "$HELPER" --get DINGTALK_MY_USER_ID | cut -d= -f2)

# 机器人单聊示例
RESP=$(curl -s -w '\nHTTP_STATUS:%{http_code}' -X POST "https://api.dingtalk.com/v1.0/robot/oToMessages/batchSend" \
  -H "x-acs-dingtalk-access-token: $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"robotCode":"'$(bash "$HELPER" --get DINGTALK_APP_KEY | cut -d= -f2)'","userIds":["'$USER_ID'"],"msgKey":"sampleText","msgParam":"{\"content\":\"测试消息\"}"}')
echo "$RESP"
#!/bin/bash
set -e
HELPER="./scripts/dt_helper.sh"
OLD_TOKEN=$(bash "$HELPER" --old-token)
AGENT_ID=$(bash "$HELPER" --get DINGTALK_AGENT_ID | cut -d= -f2)
USER_ID=$(bash "$HELPER" --get DINGTALK_MY_USER_ID | cut -d= -f2)

# 工作通知示例
RESP=$(curl -s -w '\nHTTP_STATUS:%{http_code}' -X POST "https://oapi.dingtalk.com/topapi/message/corpconversation/asyncsend_v2?access_token=$OLD_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"agent_id":"'$AGENT_ID'","userid_list":"'$USER_ID'","msg":{"msgtype":"text","text":{"content":"测试工作通知"}}}')
echo "$RESP"

Token 异常时:bash "$HELPER" --token --nocachebash "$HELPER" --old-token --nocache
