无法在 github 操作中获取发布标题

Question

我添加了 github 操作，该操作在每次发布时都会在我们的 slack 频道上发送消息。

我已经设法get repo name and tag from github context，但我也在尝试并未能在该消息中获得发布标题和发布说明。 我试过这些组合：

${{ github.event.payload.release.name || github.event.payload.release || github.event.payload }}

有人知道如何解决这个问题吗？

name: Release
on:
  push:
    tags:
      - 'v*'
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v1

      - name: Sbt
        uses: olafurpg/setup-scala@v10

      - name: Set library version
        run: ./sbt dynver

      - name: Publish stable version
        run: ./sbt publish
        env:
          JFROG_PASSWORD: ${{ secrets.JFROG_PASSWORD }}

      - name: Post to a Slack channel
        id: slack
        uses: slackapi/slack-github-action@v1.17.0

        with:
          channel-id: 'releases'
          slack-message: "Release result: ${{ job.status }}\n${{ github.repository }}: ${{ github.ref_name }}\nRelease info: ${{ github.event.payload.release.name }}, ${{ github.event.payload.release }} ${{ github.event.payload }}"
        env:
          SLACK_BOT_TOKEN: ${{ secrets.SLACK_BOT_TOKEN }}

不是在标签上触发，而是在发布创建时触发。这样发布信息就会出现。

on:
  release:
    types: [published]

标签将在github.event.release.tag_name下，发布在github.event.release.name下。

标签可以独立于版本创建，这就是原因。
