描述

https://developers.google.com/web/updates/2017/09/abortable-fetch

Currently it is only implemented in Firefox 57 and is coming to other browsers soon.

const controller = new AbortController();
const signal = controller.signal;

setTimeout(() => controller.abort(), 5000);

fetch(url, { signal }).then(response => {
  return response.text();
}).then(text => {
  console.log(text);
});

Will most likely need to implement another npm package that just include AbortController package. I found one but it also pollyfills fetch. https://github.com/mo/abortcontroller-polyfill

研究方向
Implement AbortController support for unfetch. Use an existing AbortController polyfill like 'abortcontroller polyfill' if needed. The main changes should be in the source code where fetch is implemented (likely in 'src/index.js' or similar). Ensure the signal option is passed through and that abort() aborts the request. Check the linked Google Developers article and the polyfill package for reference. Consider using a feature detection for native AbortController before loading polyfill.
