Can not upload files: No 'Access-Control-Allow-Origin' header is present on the requested resource

[Soy yo]

My webapp is running on example-domain2.com but Tinode is running on example-domain1.com.

Its not possible to upload files to the filesystem because of cors errors:

Tinode log:

I2021/02/05 21:37:51 Upload request /v0/file/u/

I2021/02/05 21:37:51 media upload: 405 operation or method not allowed / method 'OPTIONS' not allowed

Browser log:

Access to fetch at 'https://example-domain1.com:6060/v0/file/u/' from origin 'https://www.example-domain2.com' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

I tried:

I modified tinode.conf file and changed:

"fs": {

"upload_dir": "uploads"

},

to:

"fs": {

"upload_dir": "uploads",

 "cors_origins": ["*"]

},

similar like in "s3":{...} example. But it does not work either.

Any ideas how to fix this problem is there is no Access-Control-Allow-Origin header on Tinode's? Thanks.

CORS is not supported for fs. It needs to be added. I'll look into it.

I've added support in https://github.com/tinode/chat/tree/next (https://github.com/tinode/chat/commit/f3748d39ee3ec75ab272f3d3a30df33d1f56620a). Please try it out and tell me if it works as expected.

There is no release yet. You have to build it yourself from the source.
