Can We implement a custom validation mechanism?

[abdulwahid24]

Hi,

I developed a file upload API and wanted to create a custom validation based on file extension. I am using get_param method. So how can we treat file field in get_json method?

Let's me any workaround.

Thanks

How does your code look like now (with get_param)? How you wish it looked like with get_json?
