github项目：自动获取优选IP

1，在github里创建项目，例如yxip
2，在项目yxip里创建文件collect_ips.py,填入以下内容

import requests
from bs4 import BeautifulSoup
import re
import os

# 目标URL列表
urls = ['https://monitor.gacjie.cn/page/cloudflare/ipv4.html', 
        'https://ip.164746.xyz'
        ]

# 正则表达式用于匹配IP地址
ip_pattern = r'\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}'

# 检查ip.txt文件是否存在,如果存在则删除它
if os.path.exists('ip.txt'):
    os.remove('ip.txt')

# 创建一个文件来存储IP地址
with open('ip.txt', 'w') as file:
    for url in urls:
        # 发送HTTP请求获取网页内容
        response = requests.get(url)
        
        # 使用BeautifulSoup解析HTML
        soup = BeautifulSoup(response.text, 'html.parser')
        
        # 根据网站的不同结构找到包含IP地址的元素
        if url == 'https://monitor.gacjie.cn/page/cloudflare/ipv4.html':
            elements = soup.find_all('tr')
        elif url == 'https://ip.164746.xyz':
            elements = soup.find_all('tr')
        else:
            elements = soup.find_all('li')
        
        # 遍历所有元素,查找IP地址
        for element in elements:
            element_text = element.get_text()
            ip_matches = re.findall(ip_pattern, element_text)
            
            # 如果找到IP地址,则写入文件
            for ip in ip_matches:
                file.write(ip + '\n')

print('IP地址已保存到ip.txt文件中。')

3，在项目yxip里创建.github/workflows/main.yml文件，填入以下内容

name: Update IP List

on:
  schedule:
    - cron: '*/45 * * * *'  # 每45分钟更新一次
  workflow_dispatch:
  push:

jobs:
  update-ip-list:
    runs-on: ubuntu-latest
    permissions:
      contents: write  # 写入权限必须保留

    steps:
    # 关键修改点1：带token检出
    - uses: actions/checkout@v3
      with:
        token: ${{ secrets.GITHUB_TOKEN }}  # 注入认证信息
        fetch-depth: 0  # 获取完整提交历史

    # 关键修改点2：先同步最新代码
    - name: Pre-sync repository
      run: |
        git config --global user.email "tianshideyou@proton.me"
        git config --global user.name "tianshipapa"
        git remote set-url origin https://x-access-token:${{ secrets.GITHUB_TOKEN }}@github.com/camel52zhang/yxip.git
        git pull origin main  # 普通拉取最新代码

    - name: Set up Python
      uses: actions/setup-python@v4
      with:
        python-version: '3.9'

    - name: Install dependencies
      run: |
        pip install requests beautifulsoup4

    - name: Run script
      run: python ${{ github.workspace }}/collect_ips.py

    # 关键修改点3：智能提交逻辑
    - name: Commit and push changes
      run: |
        # 检测文件变化
        if [ -n "$(git status --porcelain -- ip.txt)" ]; then
          git add ip.txt
          git commit -m "Automatic update: $(date -u +'%Y-%m-%dT%H:%M:%SZ')"
          
          # 带重试的推送机制
          for i in {1..3}; do
            git pull --rebase origin main && break || sleep 5
          done
          
          git push origin HEAD:main
          echo "✅ 更新推送成功"
        else
          echo "🔄 未检测到IP变化"
        fi
