Workers
https://dash.cloudflare.com/构建无服务器应用程序并在全球范围内即时部署，从而获得卓越的性能、可靠性和规模性。
1+代访问代码块1
const hostname = "https://bk.abc.com" //http或https，含端口
function handleRequest(request) {
let url = new URL(request.url);
return fetch(new Request(hostname + url.pathname,request))
}
addEventListener("fetch", event => {
event.respondWith(handleRequest(event.request))
})
2+转发http/https 请求-代码块2
addEventListener(
"fetch",event => {
let url=new URL(event.request.url);
url.protocol="http"; //协议,http或https
url.hostname="bk.abc.com"; //域名
url.port="80"; //http或https服务的端口
let request=new Request(url,event.request);
event. respondWith(
fetch(request)
)
}
)
3+转发http/https 请求-代码块3
var host = "http://bk.abc.com";
addEventListener("fetch", (event) => {
event.respondWith(
handleRequest(event.request).catch(
(err) => new Response(err.stack, { status: 500 })
)
);
});
async function handleRequest(request) {
const url = new URL(request.url);
const newURL = new URL(host + url.pathname + url.search);
const newRequest = new Request(newURL, request);
return await fetch(newRequest);
}
4+301跳转
addEventListener('fetch', event => {
event.respondWith(fetchAndApply(event.request));
})
async function fetchAndApply(request) {
url = 'https://bk.abc.com' // 需要跳转到的地址
return Response.redirect(url, 301)

// 代理的网址.
