【问题描述】：

我遇到了这个问题：

我无法访问 apollo 服务器上下文中请求对象中的会话对象，因此我得到未定义为输出。 否则我可以正常访问快速路由内的请求对象中的会话对象。

我该如何解决？

import express,  Application, Request, Response  from 'express';
import bodyParser from "body-parser"; 
import helmet from "helmet";
import xss from 'xss';
import moment from "moment";
import passport from "passport";
import  connect  from "mongoose";
import "reflect-metadata";
import  ApolloServer  from 'apollo-server-express';
import  buildSchema, ResolverData  from "type-graphql";
// Import resolvers
import main_config from './main.config';
import AuthenticationRoutes from './Authentication/Authentication.routes';
import './Authentication/Authentication.strategies';
import  
    topicResolver, docsResolver, courseResolver, articleResolver, projectIdeaResolver 
 from './Graphql/Topics/Topics.resolvers';
import cookieSession from 'cookie-session';
import expressSession from 'express-session';
// const expGql = require("express-graphql");

const app : Application = express();

// Init cookie cookie-session
app.use(cookieSession(
    keys : ["IDFVBHNIOVFFBUE"],
    name : 'DBDIUN',
    secret : "IDFVBHNIOVFFBUE"
));

async function runapp ()
    // Ïnit passport app and routes
    app.use(passport.initialize());
    app.use(passport.session())

    // Run apollo server 
    const apollo = new ApolloServer(
        schema : await buildSchema(
            resolvers : [
                topicResolver, docsResolver, courseResolver, articleResolver, projectIdeaResolver
            ],
            globalMiddlewares: [],
        ),
        context: ( req, res ) =>
            console.log("context")
            console.log(req.session.passport) // cannot get session object then Get undefined 

            return 
                getUser: () => req.user,
                logout: () => req.logout(),
            
        ,
        playground : true
    )
    apollo.applyMiddleware( app );

    // Init body parser and helmet 
    app.use(helmet());
    app.use(bodyParser.json());

    app.use('/auth', AuthenticationRoutes)


runapp();

【参考方案1】：

不要解构 req 为我工作：

 context: (req, res) => 
    return 
      req: req,
      res: res,
    
;
