我正在尝试将express-graphql切换到apollo-server v2,但是我在迁移软件包方面遇到了困难,尤其是在使用passportjs和会话的情况下。
我当前使用express-graphql进行的设置:
const schema = include('schema')
const app = express()
app.use(bodyParser.urlencoded({ extended: false }))
app.use(bodyParser.json())
app.use(session({
secret: process.env.SESSION_SECRET,
name: 'sessionId',
resave: false,
saveUninitialized: false,
store: new MongoStore({ mongooseConnection: mongoose.connection }),
}))
app.use(passport.initialize())
app.use(passport.session())
app.use('/graphql', expressGraphQL({ schema }))
const server = http.createServer(app)
server.listen(8000, '0.0.0.0', () =>
console.log('Server running on port 8000')
)
现在使用apollo-server-express @ rc:
const schema = include('schema')
const app = express()
app.use(bodyParser.urlencoded({ extended: false }))
app.use(bodyParser.json())
app.use(session({
secret: process.env.SESSION_SECRET,
name: 'sessionId',
resave: false,
saveUninitialized: false,
store: new MongoStore({ mongooseConnection: mongoose.connection }),
}))
app.use(passport.initialize())
app.use(passport.session())
const apollo = new ApolloServer({
schema,
context: ({ req: { user, session } }) => ({ user, session })
})
apollo.applyMiddleware({ app, path: '/graphql' })
server.listen(8000, '0.0.0.0', () =>
console.log('Server running on port 8000')
)
有了这个,我得到了上下文中的user
和session
对象,并且像以前一样工作,但是当我尝试通过{{1}来login()
或logout()
个用户时}它显示context
。
好的,login is not a function
,然后再试一次,但是现在我得到了context: ({ req: { user, session, login, logout } }) => ({ user, session, login, logout })
在我不必使用express-graphql设置上下文之前,这就是我要坚持的地方。请帮忙吗?
