【中文标题】升级到 apollo-server-express 2.0.0 缺少上下文

【英文标题】：upgrading to apollo-server-express 2.0.0 context missing

【问题描述】：

升级前我们有

import express from 'express';
import  graphqlExpress, graphiqlExpress  from 'apollo-server-express';

const app = express();

app.use(
   '/graphql',
   bodyParser.json(),
   graphqlExpress(req => (
   schema,
   tracing: true,
   context:  req ,
 )),
);

app.use(
 '/graphiql',
 graphiqlExpress(
   endpointURL: '/graphql',
 ),
);

在我们的解析器中，我们可以得到 req 并设置 req.session.token 如下，

const customResover = 
Query: 
   custom: async (root, args, context) => 
   console.log(' resolver called with args', args);
   const  req  = context;  
   ... fetch token info and set 
   req.session.token = $token;
   ...

但随着升级到 2.0.0 版，代码更改为以下代码，我不确定如何修复 CustomResolver，设置会话令牌，知道如何完成上述操作吗？

import express from 'express';
import  ApolloServer, gql  from 'apollo-server-express';
import  typeDefs, resolvers  from './schema/';

const app = express();
const apollo = new ApolloServer(
   typeDefs
   resolvers,
   engine: false
);

apollo.applyMiddleware(
   app,
);

【参考方案1】：

https://www.apollographql.com/docs/apollo-server/migration-two-dot.html#request-headers

const apollo = new ApolloServer(
  typeDefs
  resolvers,
  context: ( req ) => ( req )
  engine: false
);

解决了，但是 Cookie 出现问题，令牌无法进入浏览器。
