仅用Firebase Hosting却被要求启用Cloud Functions API的问题

通过Firebase CLI初始化了仅用于Hosting的项目，并让其自动生成GitHub CI脚本，相关配置如下：

.firebaserc 配置：

{
  "projects": {
    "default": "project-name"
  }
}

firebase.json 配置：

{
  "hosting": {
    "public": "dist",
    "ignore": ["firebase.json", "**/.*", "**/node_modules/**"],
    "rewrites": [
      {
        "source": "**",
        "destination": "/index.html"
      }
    ]
  }
}

GitHub CI 脚本：

name: deploy on push
"on":
  push:
    branches:
      - main
jobs:
  build_and_deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - run: yarn && yarn build
      - uses: FirebaseExtended/action-hosting-deploy@v0
        with:
          repoToken: "${{ secrets.GITHUB_TOKEN }}"
          firebaseServiceAccount: "${{ secrets.FIREBASE_SERVICE_ACCOUNT_PROJECT_NAME }}"
          channelId: live
          projectId: project-name

但CI脚本运行时出现如下错误：

仅需使用Firebase的Hosting功能，并无启用Cloud Functions的计划，为何CI脚本会要求启用该API？过往同类项目无此要求。

原因 #

你使用的 FirebaseExtended/action-hosting-deploy@v0 版本较旧，该版本的Action默认会尝试检查项目中的Cloud Functions资源，即便你只用到Hosting服务。后续版本的Action修复了这个问题，或者提供了参数可以限定仅操作Hosting。

修复方法 #

有两种可行的解决方式：

• 升级Action版本
  将CI脚本中的 FirebaseExtended/action-hosting-deploy@v0 替换为最新稳定版（比如 v1 或更高版本），新版本默认不会检查无关的服务资源：

  - uses: FirebaseExtended/action-hosting-deploy@v1
    with:
      repoToken: "${{ secrets.GITHUB_TOKEN }}"
      firebaseServiceAccount: "${{ secrets.FIREBASE_SERVICE_ACCOUNT_PROJECT_NAME }}"
      channelId: live
      projectId: project-name
  

• 添加only参数限定服务
  如果你不想升级版本，可以在Action的with参数中添加 only: hosting，明确告知Action仅操作Hosting资源，避免触发Cloud Functions的检查：

  - uses: FirebaseExtended/action-hosting-deploy@v0
    with:
      repoToken: "${{ secrets.GITHUB_TOKEN }}"
      firebaseServiceAccount: "${{ secrets.FIREBASE_SERVICE_ACCOUNT_PROJECT_NAME }}"
      channelId: live
      projectId: project-name
      only: hosting
