TypeError:无法读取未使用TypeDi定义的属性“”authService“”

Question

我创建了一个类AuthRouter：

import { Router } from 'express'
import Container, { Service } from 'typedi'
import AuthenticationController from './index'

@Service()  
class AuthenticationRouter {
  constructor (private readonly authenticationController: AuthenticationController) {}

  getRouter () {
    const router = Router()
    router.get('/auth/url', this.authenticationController.getAuthUrl)

    return router
  }
}

const authRouter = Container.get(AuthenticationRouter)
const routes = authRouter.getRouter()

export default routes

AuthController.ts：

import { Request, Response } from 'express'
import { Service } from 'typedi'
import AuthenticationService from './authentication-service'

@Service()
class AuthenticationController {
  constructor (private readonly authService: AuthenticationService) {}

  async getAuthUrl (req: Request<{}, {}, {}, {redirect: string}>, res: Response) {
    return res.redirect(this.authService.generateAuthenticationUrl(req.query.redirect))
  }

  
}

export default AuthenticationController

AuthenticationService：

import { OAuth2Client } from 'google-auth-library'
import { google, oauth2_v2 } from 'googleapis'
import { Service } from 'typedi'


@Service()
class AuthenticationService {
  private oauth2Client: OAuth2Client;
  private auth: oauth2_v2.Oauth2
  constructor () {
    this.oauth2Client = new google.auth.OAuth2({
      clientId: process.env.CLIENT_ID,
      clientSecret: process.env.CLIENT_SECRET,
      redirectUri: process.env.REDIRECT_URI
    })
    this.auth = google.oauth2({
      version: 'v2',
      auth: this.oauth2Client
    })
  }

  generateAuthenticationUrl (redirect: string) {
    const url = this.oauth2Client.generateAuthUrl({
      scope: ['email', 'profile'],
      access_type: 'offline',
      state: redirect || '/'
    })
    return url
  }

}

export default AuthenticationService;

当我运行服务器时，我得到了这个错误：

(node:4470) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'authService' of undefined

我声明了authenticationRouter的容器，但我认为AuthController没有被注入。我怎么才能修复它呢？

我更新了getRouter方法来解决这个问题：

getRouter () {
    const router = Router()
    router.get('/google/url', (req: Request<{}, {}, {}, {redirect: string}>, res) => this.authenticationController.getAuthUrl(req, res))

    return router
  }
