CORS issue

[calumpwebb]

Hello,

I keep getting

Access to XMLHttpRequest at '{new_host}/v1/batch' from origin '{our domain}' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https.

Any fix for this?

Finding the same issue. Did you ever find solution or workaround? Thanks.

You can install the cors dependency : https://github.com/rs/cors

go get github.com/rs/cors

Then add this line juste before que "ListenAndServe"

proxy := cors.Default().Handler(proxy)

We are running into this as well, any solution?

Actualy, I noticed since then that the proxy already sends the cors headers, and if you try to add your own, you will see multiple occurences of the cors headers, which breaks everything.

The solution is to not alter the response header, and everything works fine.
