  • Workers 单页挂载代码
addEventListener('fetch', event => {
  event.respondWith(handleRequest(event.request))
})
// HTML代码
let html = `
<!DOCTYPE html>
<html>
  <head><title>Test</title></head>
  <body><div>Hello world!</div></body>
</html>
`;
/**
 * Respond to the request
 * @param {Request} request
 */
async function handleRequest(request) {
  return new Response(html, {
    headers: {
      'Content-Type': 'text/html; charset=UTF-8'
    },
    status: 200
  })
}
  • Workers 反代任意网站

两个版本代码，第一个功能多一点，第二个功能少一点，任选其一，第一个速度会快一些而且稳定。
