如何在GitHub Actions的pull_request事件中检查PR审批状态

在pull_request事件的上下文里，你可以通过github.event.pull_request.review_decision字段判断PR的整体评审状态，这个字段不需要依赖pull_request_review事件即可生效。

直接使用内置字段判断 #

review_decision的核心取值包括：

• approved：PR已满足分支保护的审批要求
• changes_requested：有评审者提出修改要求
• required：尚未完成必要的评审

你可以直接修改Workflow的if条件，用这个字段控制任务执行：

on:
  pull_request:
    branches:
      - Release
      - Production
      - Development
    types:
      - opened
      - reopened
      - synchronize

jobs:
  runTests:
    runs-on: [self-hosted]
    # 仅当PR未被审批时运行测试
    if: github.event.pull_request.review_decision != 'approved'
    steps:
      - name: Run Unit Tests
        run: |
          # 替换为你的实际测试命令
          echo "Running unit tests..."

  requestReReview:
    runs-on: [self-hosted]
    # 当PR已被审批时触发重新评审请求
    if: github.event.pull_request.review_decision == 'approved'
    steps:
      - name: Request Re-Review
        run: |
          # 替换为你的目标评审者/团队
          gh pr review ${{ github.event.pull_request.number }} --request-reviewer "reviewer1,team-name"
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

更精细的评审状态检查（可选） #

如果需要检查是否有特定评审者的审批记录，而非依赖分支保护的整体决策，可以用GitHub CLI调用API获取PR的所有评审记录，再做判断：

on:
  pull_request:
    branches:
      - Release
      - Production
      - Development
    types:
      - opened
      - reopened
      - synchronize

jobs:
  checkReviewStatus:
    runs-on: [self-hosted]
    outputs:
      has_approved_review: ${{ steps.check_review.outputs.has_approved }}
    steps:
      - name: Check PR Review Status
        id: check_review
        run: |
          # 筛选出状态为APPROVED的评审记录
          APPROVED_REVIEWS=$(gh pr reviews ${{ github.event.pull_request.number }} --state APPROVED --json state | jq 'length > 0')
          echo "has_approved=$APPROVED_REVIEWS" >> $GITHUB_OUTPUT
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

  runTests:
    runs-on: [self-hosted]
    needs: checkReviewStatus
    if: needs.checkReviewStatus.outputs.has_approved == 'false'
    steps:
      - name: Run Unit Tests
        run: echo "Running unit tests..."

  requestReReview:
    runs-on: [self-hosted]
    needs: checkReviewStatus
    if: needs.checkReviewStatus.outputs.has_approved == 'true'
    steps:
      - name: Request Re-Review
        run: gh pr review ${{ github.event.pull_request.number }} --request-reviewer "your-target-reviewers"
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

注意：使用GitHub CLI需要确保自托管运行器已安装gh工具，若未安装可在步骤中添加安装逻辑。
