CORS issues fetching data from ishare (sharepoint api )

i am developing a mashup on a qlik server where i have no resources to build a separate sever with a database. so i only have a frontend (html pages) where i want to fetch a list from sharepoint api but the CORS wont let me do that. any way to circumvent this ?

Without knowing your app, this is a bit difficult to answer, but as a quick workaround you could use a CORS proxy like

https://cors-anywhere.herokuapp.com/
or
https://crossorigin.me

However you shouldn’t use it with a production build.

thanks DanileSubat, i tried that but it didn’t work
