express-jwt 和 express-graphql：错误 TS2339：属性 'user' 在类型 'Request' 上不存在

Question

我尝试让 express-jwt 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
    }
  }))
)

我导入了相关类型 @types/express、@types/express-graphql 和 @types/express-jwt。

打字错误：

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

user 由 express-jwt 添加到请求对象上。

我该如何解决？

Answer 1

用一个属性

扩展 Express Request

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

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

express-jwt 和 express-graphql：错误 TS2339：属性 'user' 在类型 'Request' 上不存在

express-jwt and express-graphql: error TS2339: Property 'user' does not exist on type 'Request'

typescript

express-jwt

express-graphql
