我有从微软获得令牌的功能。

import { ConfidentialClientApplication } from '@azure/msal-node'
import { ConfigurationService } from './configuration/configuration.class.js'
export class TokenService {
  constructor(app) {
    this.app = app
    this.msalApplication = null
    this.accessToken = null
  }
  async initialize(configData) {
    try {
      // Find the values you need in the response data
      const clientId = configData.find((item) => item.setting === 'clientId')?.value
      const tenantId = configData.find((item) => item.setting === 'tenantId')?.value
      const clientSecret = configData.find((item) => item.setting === 'clientSecret')?.value
      // Check if all required values are present
      if (!clientId || !tenantId || !clientSecret) {
        throw new Error('Missing configuration values')
      }
      // Configure the MSAL application with the fetched values
      this.msalApplication = new ConfidentialClientApplication({
        auth: {
          clientId,
          authority: `https://login.microsoftonline.com/${tenantId}`,
          clientSecret,
          grant_type: 'client_credentials'
        }
      })
    } catch (error) {
      console.error('Error initializing TokenService:', error)
      throw error
    }
  }
  async getToken() {
    if (!this.msalApplication) {
      // Fetch the configuration values from the database using your ConfigurationService
      const configService = new ConfigurationService({
        Model: this.app.get('mssqlClient'),
        name: 'application_config' // Make sure this matches your FeathersJS database configuration
      })
      const configData = await configService.find()
      await this.initialize(configData)
    }
    // Pokud nemáme žádný platný token nebo je blízko k expiraci, získejte nový token
    if (!this.accessToken) {
      try {
        const tokenResponse = await this.msalApplication.acquireTokenByClientCredential({
          scopes: ['https://graph.microsoft.com/.default']
        })
        this.accessToken = tokenResponse.accessToken
        return this.accessToken
      } catch (error) {
        console.error('Error acquiring token:', error)
        this.accessToken = null
        throw error
      }
    }
    return this.accessToken
  }
}

它像预期的那样工作，但我需要在令牌到期前5分钟刷新它。我什么都试过了，但都不管用。当我在间隔中刷新它时，我总是得到旧的令牌。请问各位有没有解决这个问题的方法？
