Deploy workers: https://workers.cloudflare.com/
Example:
fetch('https://test.cors.workers.dev/?https://httpbin.org/post', {
method: 'post',
headers: {
'x-foo': 'bar',
'x-bar': 'foo',
'x-cors-headers': JSON.stringify({
// allows to send forbidden headers
// https://developer.mozilla.org/en-US/docs/Glossary/Forbidden_header_name
'cookies': 'x=123'
})
}
}).then(res => {
// allows to read all headers (even forbidden headers like set-cookies)
const headers = JSON.parse(res.headers.get('cors-received-headers'))
console.log(headers)
return res.json()
}).then(console.log)Note:
All received headers are also returned in "cors-received-headers" header.
Note about the DEMO url:
Abuse (other than testing) of the demo will result in a ban.
The demo accepts only fetch and xmlhttprequest.
To create your own is very easy, you just need to set up a cloudflare account and upload the worker code.
My personal thanks to Damien Collis for his generous and unique donation.
