[lawmicha]

Issue #

Description

This PR adds the ability to specify the authorization mode when making a GraphQLRequest. AppSync specific authorization modes are defined as AWSAuthorizationType in AWSPluginsCore. This a public interface from the "AWS" specific packages.

API Changes

Using GraphQLRequest builders

import Amplify
import AWSPluginsCore

try await Amplify.API.mutate(request: .create(model, authMode: .apiKey))

try await Amplify.API.mutate(request: .update(model, authMode: .apiKey))

try await Amplify.API.mutate(request: .delete(model, authMode: .apiKey))

try await Amplify.API.query(request: .query(Model.self, byIdentifier: model.identifier, authMode: .apiKey))

try await Amplify.API.query(request: .list(Model.self, authMode: .apiKey))

try await Amplify.API.subscribe(request: .onCreate(Model.self, authMode: .apiKey))

try await Amplify.API.subscribe(request: .onUpdate(Model.self, authMode: .apiKey))

try await Amplify.API.subscribe(request: .onDelete(Model.self, authMode: .apiKey))

Adding authMode parameter for all GraphQLRequest builders.

Using GraphQLRequest directly

import Amplify
import AWSPluginsCore

let request = GraphQLRequest<JSONValue>(
    apiName: apiName,
    document: documentString,
    variables: ["id": "id123"],
    responseType: JSONValue.self,
    authorizationMode: AWSAuthorizationType.apiKey)
