Nuxt.js生成sitemap.xml、seo优化、robots.txt协议添加

npm install @nuxtjs/sitemap
npm install axios

# 在第一行引入
const axios = require('axios')
# 在modules中添加@nuxtjs/sitemap
modules: [
    '@nuxtjs/sitemap'
  ],
# 在最后面添加

    path: '/sitemap.xml', // sitemap path，不用改
    hostname: 'https://www.gaozhe.net/', // sitemap网址的前缀
    cacheTime: 60 * 60 * 6, //  更新频率，只在 generate: false有用
    gzip: true, // 生成 .xml.gz 压缩的 sitemap
    generate: false, // 允许使用 nuxt generate 生成
    // 排除不要页面
    exclude: [
      '/404',
      '/page',
