cloudflare workers

1.将如下代码添加到cloudflare workers中的workers.js中

# 整体架构是这样的，这里面大部分都是正则，可以利用正则匹配来引用到其他cdn里面 这种写法比较简单，而且还能直接使用在cf里面，其他的你需要自行转换，正则匹配的路径

self.addEventListener('fetch', event => {
    const url = new URL(event.request.url);
    let newHostnameOrIp = '';

    const pathToHostMap = [

            hostname: 'fastly.jsdelivr.net'

        // 如果确实需要一个“捕获所有”的规则，请确保它是最后一个，并且前面的规则足够具体以避免不必要的覆盖
    ];

    // 遍历映射，找到匹配的路径
    for (const {
            regex,
            hostname
        }
        of pathToHostMap) {
        if (regex.test(url.pathname)) {
            newHostnameOrIp = hostname;
            break;
        }
    }

    // 如果没有找到匹配的路径，则使用原始的主机名（可选）
    if (!newHostnameOrIp) {
        event.respondWith(fetch(event.request));
        return;
    }

    // 修改请求的URL以使用新的主机名或IP
    url.hostname = newHostnameOrIp;

    // 创建新的请求对象（注意：这里不需要传递event.request作为第二个参数，因为Request构造函数不需要它）
    const newRequest = new Request(url.toString());

    // 响应新的请求
    event.respondWith(fetch(newRequest));
});

Nginx

将如下代码添加到需要反代域名的Nginx配置文件中
