Access-Control-Allow-Headers

[wanton lark]

Hi everyone! I'm trying to migrate to 2.0 and i'm struggling with writing files with Rust: (pic 1)

I couldn't find this anywhere, this is my security config: (pic 2)

How can i fix this problem? Using pic 3 Tauri version

and I also stole function from here: https://github.com/tauri-apps/tauri/issues/9322#issuecomment-2029855260

May sound random, but do you use sentry in your app?

That's the only thing i can remember that caused this issue in the past

if not, could you create a minimal reproduction repo we can test?

[wanton lark]

i dont

[wanton lark]

sure, here it is: https://github.com/MegaSa1nt/TauriCORSTest
same error for me

[wanton lark]

my app also has this unexpected border

[wanton lark]

😭
is there any way to disable cors?

[meager magnet]

only on windows with the --disable-web-security flag which we only recommend in edge cases

[wanton lark]

my app is only for windows, ill test it, thanks!

[meager magnet]

if you need cross platform support you have to use tauri's http api

which, i'd also recommend for windows because the flag is a bit extreme

the flag is for this config btw https://tauri.app/v1/api/config/#windowconfig.additionalbrowserargs

[wanton lark]

wdym http api? how can i use it for invoke?

[meager magnet]

my bad, mixed up the threads

[wanton lark]

dw

[meager magnet]

does this also happen if your command accepts Vec<u8> instead of IpcRequest?

actually, your invoke call is wrong

[wanton lark]

i took it from here

[meager magnet]

brb

[meager magnet]

So what i don't understand is how this works for them in the gh issue

I assume they tested this on Linux and webkitgtk's cors / http-request implementation is broken / doesn't follow the standards.

Because looking at tauri's code (which took a while because i haven't looked at the ipc code for ages) the error you're seeing is correct / expected

@late monolith is this intentional? On one hand we clearly set the allowed headers in ipc/protocol.rs and on the other hand we're exposing this: https://beta.tauri.app/references/v2/js/core/namespacecore/#properties-3

[wanton lark]

when using --disable-web-security flag, it just sends 400 without any error in DevTools or console

[wanton lark]

So if this error is expected and im trying to run simple invoke command, what i need to do to fix this error?

[wanton lark]

When trying to use this function with 8mb Uint8Array, it halts program for 10-20 seconds, then responding "no"

[meager magnet]

for now you'll have to remove the headers.

[wanton lark]

What about #1230067994017927179 message?
Thanks for your answers anyway

[meager magnet]

I think the is-array check logic in the ipc is wrong and it doesn't send the uint8array as binary data.

[wanton lark]

uhh, what can i do?

[late monolith]

i assume this links to the invoke headers right? we should allow any headers indeed (this is useful when the invoke body is supposed to be vec<u8> but you also want to pass other metadata - was designed for the channel api)

[late monolith]

checking it atm

the check should be right

[late monolith]

are you using the isolation pattern? i assume no right?

[wanton lark]

idk what that means 😔 i run command this way:

window.__TAURI__.core.invoke("greet", new Uint8Array(chunk), {
  headers: {
      file: 'test.mp3',
      end: "true"
  }
  }).catch(e => {
      console.log(e);
  });

[late monolith]

works fine on macOS (even the headers work fine @meager magnet 😂 maybe that's why i didn't catch that issue before - windows is my third OS pretty much)

sending a 72mb file using the IPC takes 2.5 seconds

or something like that in debug mode - my inspector is buggy for some reason

i'll try windowws

[late monolith]

a similar function works fine on my end (fixing the headers on the tauri side first ofc)

super fast

btw you should do greetMsgEl.textContent = await so you're not writing a promise to that element

[wanton lark]

sure

[late monolith]

i'm using a 27mb file this time

maybe i can just push the header fix first

https://github.com/tauri-apps/tauri/pull/9561
https://github.com/tauri-apps/plugins-workspace/pull/1251

what i've been trying is to read a large file, then writing it to a different location

with these two changes

if you can push your code to a repo I can try it too
