如何触发@github-actions机器人创建的PR中的所有检查？

先解决权限报错问题 #

你遇到的"Resource not accessible by integration"是因为默认GITHUB_TOKEN权限不足，无法操作PR检查或评论事件。先从权限配置入手：

• 进入仓库Settings → Actions → General，在「Workflow permissions」中选择「Read and write permissions」，让默认token拥有足够操作权限；
• 或者在单个Workflow的jobs节点下显式声明权限：

  permissions:
    contents: write
    pull-requests: write
    actions: write
  

方案一：在创建PR的Action中直接触发检查 #

无需额外评论触发，在cherry-pick并创建PR的Workflow末尾，直接调用GitHub API触发检查，避免多Action联动的麻烦：

1. 假设你用步骤输出了PR编号pr_number，添加以下步骤：

- name: Trigger PR checks
  run: |
    curl -X POST \
      -H "Authorization: token ${{ secrets.GITHUB_TOKEN }}" \
      -H "Accept: application/vnd.github.v3+json" \
      https://api.github.com/repos/${{ github.repository }}/pulls/${{ steps.create_pr.outputs.pr_number }}/check-runs

2. 或者通过编辑PR标题触发检查（无突兀日志）：

- name: Refresh PR to trigger checks
  run: |
    # 先给标题加标记
    curl -X PATCH \
      -H "Authorization: token ${{ secrets.GITHUB_TOKEN }}" \
      -H "Accept: application/vnd.github.v3+json" \
      https://api.github.com/repos/${{ github.repository }}/pulls/${{ steps.create_pr.outputs.pr_number }} \
      -d '{"title":"${{ steps.create_pr.outputs.pr_title }} [refresh]"}'
    # 再改回原标题
    curl -X PATCH \
      -H "Authorization: token ${{ secrets.GITHUB_TOKEN }}" \
      -H "Accept: application/vnd.github.v3+json" \
      https://api.github.com/repos/${{ github.repository }}/pulls/${{ steps.create_pr.outputs.pr_number }} \
      -d '{"title":"${{ steps.create_pr.outputs.pr_title }}"}'

方案二：修复评论触发的Action逻辑 #

如果坚持用评论触发，调整Workflow配置如下：

name: Trigger PR Checks via Comment
on:
  issue_comment:
    types: [created]

jobs:
  trigger-checks:
    runs-on: ubuntu-latest
    # 仅响应PR下的指定评论（比如/re-run-checks）
    if: github.event.issue.pull_request && contains(github.event.comment.body, '/re-run-checks')
    permissions:
      pull-requests: write
      actions: write
    steps:
      - name: Re-run PR checks
        uses: actions/github-script@v6
        with:
          script: |
            const prNumber = context.issue.number;
            // 请求重新审查（触发检查）
            await github.rest.pulls.createReview({
              owner: context.repo.owner,
              repo: context.repo.repo,
              pull_number: prNumber,
              event: 'request_review',
              reviewers: ['github-actions[bot]']
            });
            // 或者直接重新触发最近一次Workflow运行
            await github.rest.actions.reRunWorkflow({
              owner: context.repo.owner,
              repo: context.repo.repo,
              run_id: context.runId
            });
