Typescript expressjwt和expressgraphql:error TS2339:Property'；用户'；不存在于类型'；请求'；

我试图让ExpressJWT和graphql在typescript中协同工作

import * as express from 'express'
import * as expressGraphql from 'express-graphql'
import * as expressJwt from 'express-jwt'

import schema from './api/schemas'
import rootValue from './api/resolvers'

const app = express()

app.use(
  expressJwt({
    credentialsRequired: false,
    secret: process.env.JWT_SECRET
  })
)

app.use(
  '/',
  expressGraphql((req, res, graphQLParams) => ({
    schema,
    rootValue,
    context: {
      user: req.user
    }
  }))
)

我导入了相关的打字

@types/express

，

@types/express graphql

和

@types/express jwt

有一个typescript错误：

error TS2339: Property 'user' does not exist on type 'Request'

express jwt

将

user

添加到请求对象上

如何解决此问题？

使用一个属性扩展Express

请求

interface AuthRequest extends express.Request {
  user?: string
}

app.use(
  '/',
  expressGraphql((req: AuthRequest, res, graphQLParams) => ({
    schema,
    rootValue,
    context: {
      user: req.user
    }
  }))
)
