Access to native error / request error type to differentiate network errors about nativescript-http HOT 2 OPEN

Hey!

At this moment, I don't think it's possible to get the original native error. I'm also not sure whether NativeScript has something to provide in that. It's probably better to transform these errors in the plugin to standardized TypeScript errors.
I would accept Pull Requests for that.

Thanks for the answer.

We cannot get the actual native error indeed, I meant the 'wrapped' Javascript version.

On iOS the error returned by session.dataTaskWithRequestCompletionHandler(urlRequest, function (data, response, error) {...} seems to be a 'wrapped' Javascript NSError. On Android though, I'm not sure what errors are mapped to (probably some subclass of a java Exception ?).

I guess it would be somewhat complicated to map iOS NSErrors and Android Exceptions to various error types (no network, timeout etc...) but it might be nice to have a way to retrieve the 'original' (but not native :) ) error.

I'm not super familiar with TypeScript errors, but it looks like one would have to create a subclass for that ? (And add an nativeError / underlyingError property to the Error class).

I don't have a lot of time to delve more into this right now but may try to make a pull request later.
