How to create/get a bean of DataFetchingEnvironment with RequestScope?

[danielborges93]

I want to get a instance of DataFetchingEnvironment per scope as a bean in my code.

My motivation is to get the request authorization header per each request without passing the DataFetchingEnvironment as a resolver method param. What is the best way to do this?

Thanks!

I have the exact same issue, would like to access request information in a layered architecture, without having to pass it from the resolver through each method, maybe by injecting it through some bean in the level i want, is that possible?

@danielborges93 @aymanmoukhtar : I haven't tested it, but have you tried creating a bean with Session scope and manipulate/set the POJO variables at the base query level (once), based on DataFetchingEnvironment and inject it wherever else you need? That should provide you exactly what you need.

Assuming both use cases are security related then I'd advise to add Spring Security to the mix. That's what we use in all our projects. A custom Spring Security filter parses and authorizes the Authorization request header even before it hits the GraphQL resolvers. This means that in the resolver methods but even anywhere down the line you can get a hold of the authenticated principal using default Spring Security mechanisms, e.g. SecurityContextHolder.getContext().getAuthentication().

How about the case when it's not security related? Say we want to get locale header from GraphQL request and pass it to resolvers via some global configuration?

In that case you should try the approach suggested by @neerajsu: #438 (comment).
