如何在nuxt.config.js中访问参数

Question

我在nuxt.config.js中有publicRuntimeConfig

  publicRuntimeConfig: {
    baseURL: process.env.BASE_URL || 'https://www.mywebsite.com',
    baseCDN: process.env.BASE_CDN || '',
    logoWhite: THISFROMBASECDN + '/images/logowhite.png',
    logoColor: THISFROMBASECDN + '/images/logocolor.png'
  },
  privateRuntimeConfig: {},
  head: {
    meta: 
    link: [
      { rel: 'icon', type: 'image/x-icon', href: THISFROMBASECDN + '/images/myicon.png' }
    ]
  },

如何在 THISFROMBASECDN 中访问参数baseCDN，因此，如果更改CDN URL，则只需更改baseCDN参数。

谢谢你
