&lt;p>由于对国内云厂商的厌恶提升，且为了blog服务性能提升，这里将博客静态资源从腾讯云迁移到 Cloudflare R2，其实步骤还是挺繁琐的，包括 rclone 配置、Worker 部署和自定义域名绑定。但得益于AI协助，整个迁移过程大概 1 小时，0.5G 静态资源零停机切换完成。这里大概记录下完整步骤，供大家参考。&lt;/p>

&lt;/h2>&lt;p>将静态资源从腾讯云迁移到 Cloudflare R2 主要有两个目的：&lt;/p>
&lt;ol>
&lt;li>&lt;strong>降低成本&lt;/strong>：Cloudflare R2 出口流量完全免费，后期计划废弃服务依赖国内云，实在是从登录到使用充满了流氓气息。&lt;/li>
&lt;li>&lt;strong>提升性能&lt;/strong>：利用 Cloudflare 全球 CDN 加速，优化博客访问速度和 SEO&lt;/li>
&lt;/ol>

&lt;/h2>&lt;p>通过这次迁移实现了：&lt;/p>
&lt;p>✅ &lt;strong>成本优化&lt;/strong>：R2 出口流量 $0&lt;br>
✅ &lt;strong>性能提升&lt;/strong>：Cloudflare 全球 CDN 加速&lt;br>
✅ &lt;strong>架构优化&lt;/strong>：Private Bucket + Worker 的标准实践&lt;br>
✅ &lt;strong>零停机迁移&lt;/strong>：URL 保持不变，用户无感知&lt;/p>
&lt;p>整个迁移过程仅耗时 &lt;code>1 小时&lt;/code>，0.5G 静态资源全部迁移完成。这是 Cloudflare R2 + Worker 做法。&lt;/p></description></item></channel></rss>
