前言

Cloudflare大善人的Workers可以搭建节点，大佬们靠爱发电更新的proxyip一直不稳定，导制很多cloudflare网站打不开。今天闲下来了配置一个自动抓取proxyip然后DDNS更新。

效果演示：

配置教程：

• github创建一个项目，在项目根目录创建 .github/workflows/update-proxy-ip.yml。添加下面代码，代码在最后面。

• 在GitHub仓库的Settings → Secrets中添加：
  • CLOUDFLARE_ZONE_ID：应该是类似 a1b2c3d4e5f6g7h8i9j0 的字符串
  • CLOUDFLARE_API_TOKEN：以 Bearer 开头的API令牌
  • DOMAIN_NAME：完整的域名，如 proxy.example.com

• 手动运行一次，看ip有没有保存到仓库。

• 运行完成无报错，看DDNS更新没有。更新了即成功！

至此结束！不知道cf proxyip用法的自己百度。

最后附上github脚本代码：

name: Update Proxy IP and Cloudflare DNS
on:
  schedule:
    - cron: '0 */6 * * *'  # 每6小时运行一次
  workflow_dispatch:  # 允许手动触发
permissions:
  contents: write  # 添加写入权限
jobs:
  update-proxy-ip:
    runs-on: ubuntu-latest

        # 检查文件是否包含有效IP
        if [ ! -s proxyip.txt ]; then
          echo "Error: Failed to fetch proxy IPs"
          exit 1
        fi

        # 提取第一个IP地址
        FIRST_IP=$(head -n 1 proxyip.txt | grep -Eo '([0-9]{1,3}\.){3}[0-9]{1,3}')

        if [ -z "$FIRST_IP" ]; then
          echo "Error: No valid IP found in the file"
          exit 1
        fi

        echo "First IP: $FIRST_IP"
        echo "FIRST_IP=$FIRST_IP" >> $GITHUB_ENV
