I had this working months ago but now I can't figure out how I did it for the life of me.

I want to make a post request to a server i'm running on localhost using the fetch api. I can run Get requests with no troubles but the POST requests always fail, regardless of browser. I get a TypeError: Failed to execute 'fetch' on 'Window': Invalid referrer policy error every time. The server is set to allow cors for "*".

My request looks like this:

val requestOpts = RequestInit().apply {
    method = "POST"
    body = JSON.stringify(postData)
}

window.fetch("<http://localhost:7000>", requestOpts).then { console.log("Post success!" }.catch { console.log("Whomp whooooomp") }

@chadmorrow try with referrerPolicy = "" in RequestInit

That just about did the trick I think. The promise did come back successfully and the server received the data but I got this error in the console:

Error parsing 'integrity' attribute ('null'). The hash algorithm must be one of 'sha256', 'sha384', or 'sha512', followed by a '-' character.

[chadmorrow]

seems like there may just need to be better default values provided for the RequestInit

[chadmorrow]

Yeah, passing an empty string in for integrity takes care of that and there are no more errors

[chadmorrow]

awesome, thanks for the suggestion @samir

[samir]

Yes, empty string solves it. np

I agree about the default values, needs some tweaking.

Could you please file an issue?
