How to get request headers when resolving field?

[paymog]

What's the right way to get request header when resolving a query/mutation? A related issue, #17, lead me to believe that info.context.headers will work but I'm finding that doesn't exist when I try to print it:

 ❮❮❮ curl -i -H 'Content-Type: application/json' -H 'x-authorization-info: testing' -X POST -d '{"query": "query { latestSnapshot { url } }"}' http://localhost:5000/graphql
HTTP/1.0 200 OK
Content-Type: application/json
Content-Length: 160
Server: Werkzeug/0.14.1 Python/3.6.7
Date: Thu, 18 Apr 2019 22:21:51 GMT

{"errors":[{"message":"'dict' object has no attribute 'headers'","locations":[{"line":1,"column":9}],"path":["latestSnapshot"]}],"data":{"latestSnapshot":null}}% 

with a resolver of:

    def resolve_latest_snapshot(self, info: ResolveInfo, org_id: Optional[int] = None) -> models.Snapshot:
        print(info.context.headers)
        # more stuff

I have flask-graphql version 2.0.0.

EDIT: other related packages I have:

graphene==2.1.3
graphql-core==2.1
graphql-relay==0.4.5
graphql-server-core==1.1.1
graphene-sqlalchemy==2.1.1

Oh, looks like

from flask import request

def resolve_latest_snapshot(self, info: ResolveInfo, org_id: Optional[int] = None) -> models.Snapshot:
    print(request.headers)
    # more stuff

works. I wonder if there's a better, more graphene-y solution...

Looks like context is request (if you haven't overrided it): https://github.com/graphql-python/flask-graphql/blob/master/flask_graphql/graphqlview.py#L41

So probably info.context is request, and headers are in info.context.headers, but I haven't verified it.

Oh yup, you're right. I was overriding it but now I've added it back in. Thanks!

When trying to access info.context in mutation I get

"graphql.error.located_error.GraphQLLocatedError: Working outside of request context"

Pretty simple setup:

class SomeMutation(graphene.Mutation):
    """
    """

    def mutate(self, info):
        """
        """

        print(info.context)
         ... snip...

        return

class Mutation(graphene.ObjectType):
    """
    """

    some_mutation = SomeMutation.Field()

schema = graphene.Schema(query=Query, mutation=Mutation, subscription=Subscription)

app.add_url_rule('/graphql',
    view_func=GraphQLView.as_view('graphql',
        schema=schema,
        batch=True,
        graphiql=False,
        executor=GeventExecutor(),
    )
)
