Beacon API

User Tracking

https://caniuse.com/#feat=beacon

Question & Solution

Beacon API 不会延缓网页卸载,不会严重影响用户体验。

为了解决网页卸载时,异步请求无法成功的问题,浏览器特别实现了一个 Beacon API,允许异步请求脱离当前主线程,放到浏览器进程里面发出,这样可以保证一定能发出。

navigator.sendBeacon()方法可以保证,异步请求一定会发出;
第一个参数是请求的网址,第二个参数是发送的数据;

Beacon API 发出的是 POST 请求。


window.addEventListener('click', function (event) {
  navigator.sendBeacon('/graphql/api/v3/logs', 'event=click');
});
