Bearer Authorization Headers with saveAs proxy
Is it possible to set Authorization headers when using a proxy with the kendo-file-saver saveAs function? The controller method I am trying to use as the proxy is protected by JWT Bearer token authorization.

Hi,

We are declining this request due to the current level of interest and demand.

However, if interest in this feature increases significantly in the future, we will reconsider its status and evaluate it again.

Unfortunately we are serving many different file types.

Please do open up a feature request to set JWT Bearer Authorization headers for the proxyURL in saveAs. 

We've worked around this for now using a separate library, but saveAs would be much cleaner.

 

Thanks!

Hello, Spencer,

If this is for PDF files, I can suggest the following approach.

Convert the file to a Base64 string and programmatically make the request with the generated string with a library like axios:

https://stackoverflow.com/questions/51586458/how-to-pass-header-jwt-token-with-axios-react/51588921

Also, if you wish I can convert this to a public feature request, where the community can vote for this feature to be added to the saveAs method.
