折腾博客 之 通过Freshrss API实现朋友文章

折腾博客 之 通过Freshrss API实现朋友文章

之前玩静态博客用过hexo-circle-of-friends来获取友情链接中的好友文章. 如今这个项目我部署的过程中总是出现各种意外,不想继续折腾了,于是想起在大佬处看到 用FreshRSS 实现友圈rss订阅 于是开始今日的折腾

Docker部署Freshrss

使用docker run 命令

docker run -d --restart unless-stopped --log-opt max-size=10m \
  -p 8282:80 \
  -e TZ=Asia/Shanghai \
  -e 'CRON_MIN=1,31' \
  -v /root/rss/data:/var/www/FreshRSS/data \
  -v /root/rss/extensions:/var/www/FreshRSS/extensions \
  --name freshrss \
  freshrss/freshrss

获取API密码

  1. 认证中打开允许 API 访问 (用于手机应用)选项
  2. 账户-API管理中输入API密码

CF Workers

这时候就要使用CF大法了.

            description: short_desc,
            icon: subscription ? `${siteurl}/${subscription.iconUrl.split('/').pop()}` : ''
        };
    });
}

function stripHtml(html) {
    return html.replace(/<[^>]*>?/gm, ''); // 使用正则表达式去除HTML标签
}

访问看看,输出 https://rss.imsun.workers.dev/ 由于cf的加载速度不是很理想,当然也可以使用php或者bash脚本生成json文件,这样可以加速页面加载的速度,大佬已经有代码贴出来了我就不复制了. 如果是使用静态博客的话 则可以选择使用github工作流 生成静态文件并通过vercel加速访问

调用

我把朋友圈文章加在了友情链接页面

使用php
