RequestHeader for get headers in query

Hi!, I trying to get header user agent and another params.

I try this:

@GraphQLQuery(name = "getByCode")
	public UserDTO getByCode(@GraphQLArgument(name = "code") Date code, @RequestHeader(value="User-Agent") String userAgent) {
		
		
		UserDTO out = new UserDTO();
		return out;
	}

And this:

@GraphQLQuery(name = "getByCode")
	public UserDTO getByCode(@GraphQLArgument(name = "code") Date code, @ServletRequest request) {
		
		
		UserDTO out = new UserDTO();
		return out;
	}

How i can get the headers?

Thanks!

By default, SPQR Spring Boot Starter will use DefaultGlobalContext which contains the original request, as you have found out.

You can inject the context using @GraphQLRootContext:

public ResponseDTO buscoYOfrezco(
	 @GraphQLArgument(name = "busco") String busco, 
	@GraphQLArgument(name = "ofrezco") String ofrezco,
	@GraphQLRootContext DefaultGlobalContext context) {
...
}

You can also register a custom ArgumentInjector that would recognize Spring annotations like @RequestHeader. Take a look at the context injector for inspiration.

SPRQ Spring module will eventually have this built-in, but it’s easily added manually as well.

@dguduguntla Yes, that would be correct. You can also create a custom ArgumentInjector to use a custom annotation (e.g. @HttpHeader("Authorization")) for the same purpose. Or if you’re using Spring, you can use Spring’s @RequestHeader("Authorization") annotation. Again, this is not built-in (will be soon), but it’s very easy to add yourself. But, since this is about authorization, the best place to implement such concerns is actually in a ResolverInterceptor. See this test for an example.
