参考：
https://developer.aliyun.com/article/1540773
https://github.com/ViggoZ/producthunt-daily-hot/blob/main/.github/workflows/generate_markdown.yml

1、创建github项目

在这里插入图片描述
目录：
.github/workflows/fetch-news.yml actions执行yaml（必须这样的目录结构）
fetch-news.py 是python脚本

fetch-news.py

import random

def generate_random_number():
    random_number = random.randint(1, 100)  # 生成1到100之间的随机数
    with open("news.txt", "w") as file:
        file.write(f"Random Number: {random_number}\n")

if __name__ == "__main__":
    generate_random_number()

2、构建actions ymal文档

.github/workflows/fetch-news.yml

cron 程序执行周期
token 是秘钥
git push https:// ${{ secrets.PAT }}@github.com/$ {{ github.repository }}.git HEAD:${{ github.ref }} 内容在同步到github上

name: Fetch Latest News

on:
  schedule:
    - cron: '*/5 * * * *'  # 每5分钟运行一次

jobs:
  fetch-news:
    runs-on: ubuntu-latest

    steps:
    - name: Checkout code
      uses: actions/checkout@v2
      with:
        token: ${{ secrets.PAT }}  # 使用 PAT 进行 checkout

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

    - name: Install dependencies
      run: |
        python -m pip install --upgrade pip
        pip install requests

    - name: Fetch news
      run: |
        python fetch_news.py

    - name: Commit and push news
      run: |
        git config --global user.name "github-actions[bot]"
        git config --global user.email "github-actions[bot]@users.noreply.github.com"
        git add news.txt
        git commit -m "Update news"
        git push https://${{ secrets.PAT }}@github.com/${{ github.repository }}.git HEAD:${{ github.ref }}
      env:
        PAT: ${{ secrets.PAT }}
