在 GitHub Actions 中捕获 Firebase 部署 URL

Question

我正在尝试修改自动生成的 Firebase 部署工作流程。

我想捕获部署 URL 并将其吐出到摘要页面。部署步骤会在日志中返回 url：

Deploying to Firebase preview channel pr---my-branch
  /usr/local/bin/npx firebase-tools@latest hosting:channel:deploy pr---my-branch --expires 7d --project my-project --json
  npm WARN exec The following package was not found and will be installed: [email protected]
  ***
    "status": "success",
    "result": ***
      "my-project": ***
        "site": "my-project",
        "url": "https://my-project--pr-my-branch-w97r0jc8.web.app",
        "version": "",
        "expireTime": "2024-01-19T20:51:42.668928198Z"
      ***
    ***
  ***::endgroup::
  ***
    details_url: 'https://my-project--pr-my-branch-w97r0jc8.web.app',
    conclusion: 'success',
    output: ***
      title: 'Deploy preview succeeded',
      summary: '[https://my-project--pr-my-branch-w97r0jc8.web.app](https://my-project--pr-my-branch-w97r0jc8.web.app)'
    ***
  ***

到目前为止我都失败了。因此我尝试从相同的 GitHub 变量构建它：

# This file was auto-generated by the Firebase CLI
# https://github.com/firebase/firebase-tools

name: Deploy to Firebase Hosting on demand
"on":
  workflow_dispatch:
jobs:
  build_and_preview:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - run: npm ci && npm run build
      - id: deploy
        uses: FirebaseExtended/action-hosting-deploy@v0
        with:
          repoToken: "${{ secrets.GITHUB_TOKEN }}"
          firebaseServiceAccount: "${{ secrets.FIREBASE_SERVICE_ACCOUNT }}"
          projectId: my-project
          channelId: "pr-${{ github.event.number }}-${{ github.event.pull_request.head.ref }}-${{ github.head_ref || github.ref_name }}"
      - name: Set step summary
        run: echo '🚀[Preview URL](https://my-project--pr-${{ github.event.number }}-${{ github.event.pull_request.head.ref }}-${{ github.head_ref || github.ref_name }}.web.app)' >> $GITHUB_STEP_SUMMARY

结果是：

https://my-project--pr---my-branch.web.app/

我想要得到的是：

https://my-project--pr-my-branch-w97r0jc8.web.app

我需要了解

w97r0jc8

部分的来源并重建创建 URL 的方式，或者从前面步骤的日志中捕获实际的 URL。请指教。

我还了解到，仅当工作流程由

github.event.number

触发时，

github.event.pull_request.head.ref

、

github.head_ref

和

pull_request

才可用，因此对于手动调度的工作流程，我可能需要以不同的方式进行此设置。

pull_request

触发了一个。

事实证明这很容易......荣誉@jonrsharpe！对于其他陷入困境的人，以下是如何获取某个步骤的输出变量：

  - name: Set step summary
    run: echo '🚀[Preview URL](${{ steps.deploy.outputs.details_url }})' >> $GITHUB_STEP_SUMMARY
