修改URL并重定向

代码

const base = "https://demo.aliyundoc.com/";
const statusCode = 301;

async function handleRequest(request) {
  const url = new URL(request.url);
  const { pathname, search } = url;

  const destinationURL = base + pathname + search;

  return Response.redirect(destinationURL, statusCode);
}

addEventListener("fetch", async event => {
  event.respondWith(handleRequest(event.request));
});

结果

请求的URL被边缘程序替换成了demo.aliyundoc.com域名并返回301重定向。
