用 PushDeer 给你的网站添加一个实时反馈页面吧

关于 PushDeer： https://github.com/easychen/pushdeer

首先你要设置好你的 PushDeer 以确保你可以通过调用 APi 在手机上收到消息。

然后你需要在你的网站上添加一个 iframe：

<iframe src="https://pushdeer-form.jwenjian.workers.dev/?pushkey=<替换成你的 pushkey>" width=100% height=400 />

然后你的用户就可以看到下面的页面：

用户输入信息之后，点击 send ，如果下面显示 OK ，你的手机过一会就回收到通知了

可以去我的页面试试：

good luck

另外，之所以没有在页面直接发起，是因为 push deer 的 api 没有开启 CORS ，所以中间过了一个 cloud flare 的 workers ，你也可以自己实现一套这个页面。

workers 脚本：

addEventListener("fetch", (event) => {
  event.respondWith(
    handleRequest(event.request).catch(
      (err) => new Response(err.stack, { status: 500 })
    )
  );
});

async function handleSend(url) {
  try {
      let searchParams = new URLSearchParams(url.search)
let resp = await fetch("https://api2.pushdeer.com/message/push?pushkey=" +
            searchParams.get('pushkey') +
            "&text=" +
            searchParams.get('text'));
  let json = await resp.json();
  let obj = {
      code: 0
      }
  return new Response(JSON.stringify(obj), {
    headers: {
      'Content-Type': 'application/json; charset=UTF-8'
    },
    status: 200
  })
  } catch(e) {
    let obj = {
        code: -1
    }
    return new Response(JSON.stringify(obj), {
    headers: {
      'Content-Type': 'application/json; charset=UTF-8'
    },
    status: 500
  })
  } 
  
  
}
/**

async function handleRequest(request) {
  let url = new URL(request.url)
  if (url.pathname === '/send') {
    return handleSend(url)
  }

你可以把它部署到你的 workers 账号下面，以防我的免费额度用完，没法继续使用。
