GqlExecutionContext.create(context).getContext().reqって？

バージョン

6.7.1

結論

Expressのresだった

きっかけ

GraphQLとpassportの連携時

import { ExecutionContext, Injectable, Logger } from '@nestjs/common';
import { GqlExecutionContext } from '@nestjs/graphql';
import { AuthGuard } from '@nestjs/passport';

@Injectable()
export class GqlAuthGuard extends AuthGuard('oauth2-client-password') {
  getRequest(context: ExecutionContext) {
    const ctx = GqlExecutionContext.create(context);
    const request = ctx.getContext().req;
    /*
    for (var n in request) {
      if (typeof request[n] === 'function') {
        Logger.log(n);
      }
    }
    */
    Logger.log(request.params);
    Logger.log(request.body);
    Logger.log(request.query);
    return request;
  }
}

ちなみに、graphql-tagでrequest.body.queryをパースした結果
