如何集成Neo4j数据库、NestJS框架和GraphQL？

我正在尝试将我的 REST API (NestJS) 与带有 GraphQL 查询的新 Neo4j 数据库集成。有人成功吗？提前致谢

编辑1：（我添加了我的代码）

import { Resolver } from "@nestjs/graphql";
import { Query, forwardRef, Inject, Logger } from "@nestjs/common";
import { Neo4jService } from "src/shared/neo4j/neoj4.service";
import { GraphModelService } from "./models/model.service";
import { Movie } from "src/graphql.schema";

@Resolver('Movie')
    export class GraphService {
    constructor(private readonly _neo4jService: Neo4jService) {}

    @Query()
    async getMovie() {
        console.log("hello");
        return neo4jgraphql(/*i don't know how get the query and params*/);
    }
}

我正在使用一个NestInterceptor为了实现这一点：

@Injectable()
export class Neo4JGraphQLInterceptor implements NestInterceptor {
  intercept(
    context: ExecutionContext,
    next: CallHandler<any>,
  ): Observable<any> | Promise<Observable<any>> {
    const ctx = GqlExecutionContext.create(context);
    return neo4jgraphql(
      ctx.getRoot(),
      ctx.getArgs(),
      ctx.getContext(),
      ctx.getInfo(),
    );
  }
}

要在您的Resolver:

@Resolver('Movie')
@UseInterceptors(Neo4JGraphQLInterceptor)
export class MovieResolver {}

My GraphQLModule配置如下：

@Module({
  imports: [
    GraphQLModule.forRoot({
      typePaths: ['./**/*.gql'],
      transformSchema: augmentSchema,
      context: {
        driver: neo4j.driver(
          'bolt://neo:7687',
          neo4j.auth.basic('neo4j', 'password1234'),
        ),
      },
    }),
  ],
  controllers: [...],
  providers: [..., MovieResolver, Neo4JGraphQLInterceptor],
})

注意使用transformSchema: augmentSchema启用自动生成的突变和查询（GRANDStack：模式增强 https://grandstack.io/docs/neo4j-graphql-js.html#schema-augmentation)

希望有点帮助！
