Question

我最近已将服务器项目从javascript切换为打字稿，并且正在清理一些代码。我曾经将一些Google护照Oauth资料和登录路线保存在单独的文件中，但决定将它们组合在一起。在此过程中，我破坏了一些代码，并且不明白为什么会发生错误或如何修复该错误。预先感谢！

我知道错误发生在server.express.use(auth.initialize())行的index.ts中。我收到错误消息UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): TypeError: Cannot read property 'initialize' of undefined，您能帮我发现我在做什么吗？

index.ts

import { createTypeormConn } from './db/createConn'
import schema from './graphql'
import { pubsub } from './graphql/PubSub'
import * as auth from './middleware/auth'
const express = require('express')
const { GraphQLServer, PubSub } = require('graphql-yoga')
const cookieSession = require('cookie-session')
const cors = require('cors')
const path = require('path')

export const startServer = async () => {
    await createTypeormConn()
    const corsOptions = {
        origin: [
            //omitted for brevity
        ],
        credentials: true
    }

    const options = {
        port: process.env.PORT || 1337,
        endpoint: '/api',
        subscriptions: '/api',
        playground: '/playground'
    }

    const server = new GraphQLServer({
        schema,
        context: req => ({ pubsub, request: req.request })
    })

    server.express.use(
        cookieSession({
            maxAge: 24 * 60 * 60 * 1000,
            keys: [''] //omitted
        })
    )

    server.use(cors(corsOptions))
    server.express.options('/api', cors(corsOptions))
    server.express.use(auth.initialize()) //fails during initialize
    server.express.use(auth.session())
    server.express.use('/auth', auth.routes)
    server.express.use('/', express.static(path.join(__dirname, 'site')))
    server.start(options, ({ port }) => {
        console.log(`Server is running on localhost:${port}`)
    })
}
startServer()

import { User } from '../db/orm'
import * as passport from 'passport'
import { Router } from 'express'
import { OAuth2Strategy } from 'passport-google-oauth'

passport.serializeUser<any, any>((user, done) => {
    done(null, user.id)
})

passport.deserializeUser((id, done) => {
    User.findOne(id).then(user => {
        done(null, user)
    })
})

passport.use(
    new OAuth2Strategy(
        {
            callbackURL: '/auth/google/redirect',
            clientID:'', //omitted
            clientSecret: '' //omitted
        },
        async (accessToken, refreshToken, profile, done) => {
            //omitted
            return done(null, user)
        }
    )
)

const routes = Router()

routes.get('/google/start', (req, res) => {
    passport.authenticate('google', {
        scope: ['profile'],
        state: req.query.stream
    } as any)(req, res)
})

routes.get('/google/redirect', passport.authenticate('google'), (req, res) => {
    //omitted    
})

const initialize = passport.initialize
const session = passport.session
export { initialize, session, routes }

您正在丢失this的{{1}}上下文。替换：

passport

具有：

const initialize = passport.initialize
const session = passport.session

初始化Google Passportjs策略错误
