ExecutionContext

https://docs.nestjs.com/fundamentals/execution-context

• ExecutionContext
  • HTTP
    • GraphQL: GqlExecutionContext
  • RPC
  • WebSocket

	http	graphql
context	context.switchToHttp()	GqlExecutionContext.create(context).getContext()
request	context.switchToHttp().getRequest()	GqlExecutionContext.create(context).getContext().req
response	context.switchToHttp().getResponse()	GqlExecutionContext.create(context).getContext().res

• 고려대상
  • @UseInterceptors(LoggingInterceptor)
  • @RequestHeader() - https://github.com/nestjs/nest/issues/4798
  • @User() - @UseGuards(AuthGuard) 이후의 user 가져오는
  • @UseFilters(ExceptionFilter)

HTTP용과 GraphQL용을 구분해서 각각 만들어도 되고,
서로 다른 context의 출발점을 구분하여 하나로 만들어도 된다.
