在GitHub Actions中，可以通過(guò)以下步驟實(shí)現(xiàn)對(duì)評(píng)論的自動(dòng)回復(fù)：

1. 創(chuàng)建一個(gè)名為.github/workflows/main.yml的文件，并在其中定義一個(gè)名為post-push的GitHub Action。

2. 在post-push文件中，編寫以下代碼：

name: Auto reply on comments

on: [push]

jobs:
  auto-reply:
    runs-on: ubuntu-latest

    steps:
    - name: Checkout repository
      uses: actions/checkout@v2

    - name: Set up Python environment
      uses: actions/setup-python@v2
      with:
        python-version: 3.8

    - name: Install required packages
      run: |
        pip install requests

    - name: Send automated reply to comments
      run: |
        for comment in $(git log --pretty=%d -- $GITHUB_SHA) | grep -E '^[0-9]+$' | awk '{print $1}'; do
          echo "Auto reply: $comment" >> /tmp/auto_reply.txt
        done

1. 保存文件并運(yùn)行gh-action-dispatch create-repo-action命令，創(chuàng)建一個(gè)新的GitHub Action。

2. 將新創(chuàng)建的Action添加到現(xiàn)有的main.yml文件中，例如：

name: Auto reply on comments

on: [push]

jobs:
  main:
    runs-on: ubuntu-latest

    steps:
    - name: Checkout repository
      uses: actions/checkout@v2

    - name: Set up Python environment
      uses: actions/setup-python@v2
      with:
        python-version: 3.8

    - name: Install required packages
      run: |
        pip install requests

    - name: Send automated reply to comments
      run: |
        for comment in $(git log --pretty=%d -- $GITHUB_SHA) | grep -E '^[0-9]+$' | awk '{print $1}'; do
          echo "Auto reply: $comment" >> /tmp/auto_reply.txt
        done

1. 最后，確保你的GitHub賬戶具有足夠的權(quán)限來(lái)執(zhí)行此操作。
