CORS via Greasemonkey/Tampermonkey
当前为
This script enables web front-end developers to bypass CORS to directly access other domains in the easiest and no-fuss way.
The most important update of v2.0 compared to v1.0 is that it supports response data other than text!
(Just install this script and open the console on this page to try it out!)
Simplest trial
CORSViaGM.init()
fetch('https://example.com')
(Bad fun)
Replace any first picture on the current page with the DuckDuckGo icon
CORSViaGM.init()
url = 'https://duckduckgo.com/favicon.ico'
img = Object.assign(new Image, { src: URL.createObjectURL(await (await fetch(url)).blob()) })
document.querySelector('img')?.replaceWith(img)
(More advanced)
If you want to await window._CORSViaGM.inited, add the following element to the <head> of your index.html:
<script>
window._CORSViaGM = (inited => ({ inited: Object.assign(new Promise(r => inited = r), { done: inited }) }))()
</script>
