testing with curl, issues

i added the package to my setup, and tried to test it using curl from the example of https://github.com/jaydenseric/graphql-multipart-request-spec, i guess it should be working. modified a bit.

upload mutation:

class UploadMutation(graphene.Mutation):
    class Arguments:
        file = Upload(required=True)

    success = graphene.Boolean()

    def mutate(self, info, file, **kwargs):
        # file parameter is key to uploaded file in FILES from context
        uploaded_file = info.context.FILES.get(file)
        # do something with your file
        return UploadMutation(success=True)

class Mutation(graphene.ObjectType):
    upload_mutation = UploadMutation.Field()

i did the ModifiedGraphQLView modification as well.

when i run the current command:

curl http://localhost:8000/graphql -F operations='{ "query": "mutation ($file: Upload!) {
 uploadMutation(file: $file) { id } }", "variables": { "file": null } }' -F map='{ "0": ["variables.file"] }' -F 0=@"C:\
Users\William S. Hansen\Documents\upload.txt"

i only changed the mutation name, the uri, and the path to the file.

i get the following error:

Internal Server Error: /graphql

json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes: line 1 column 3 (char 2)

is it the request that is wrong, or what am i not getting?

what is it with those double quotes?

it seems like the curl command is also complaining a bit, from the terminal:

curl: (6) Could not resolve host: ($file
curl: (6) Could not resolve host: Upload!)
curl: (3) [globbing] unmatched brace in column 1
curl: (6) Could not resolve host: uploadMutation(file
curl: (6) Could not resolve host: $file)
curl: (3) [globbing] unmatched brace in column 1
curl: (6) Could not resolve host: id
curl: (3) [globbing] unmatched close brace/bracket in column 1
curl: (3) [globbing] unmatched close brace/bracket in column 1

thanks 😃

I’ve been getting {"errors":[{"message":"Must provide query string."}]} for the last 2 hours and have been banging my head over this. Turned out it was because I didn’t replace GraphQLView.as_view with FileUploadGraphQLView.as_view in urls.py (which is described in the README for django integration – in case this may help someone else out there.

I made it work. Thanks a lot. I was using the GraphQL, not using the “Multipart form” in insomnia.
