vuepress设置跨域代理

vuepress怎么设置跨域请求？
最近在用vuepress2.x编辑自己的博客，想用第三方接口获取数据，但是遇到跨域问题，在vue里面用config.js可以设置，但是在vuepress的config.js设置怎么不行？还是说需要在哪里设置？

• 文章：Vuepress里如何显示代码块 中也许有你想要的答案，请看下吧
• 除此之外, 这篇博客: VuePress搭建博客教程(五)、vuepress侧边栏设置中的 一、修改confi.js 部分也许能够解决你的问题, 你可以仔细阅读以下内容或跳转源博客中阅读:
  

• 因为所有配置都在config.js中，会显得特别直观，所以我们整改一下目录结构。config.js如下：

  module.exports = {
      title: "小景哥哥",
      description: "小景哥哥带你上王者",
      port: "80",
      head: [
          ["link", {rel: "icon", href: "/logo.jpg"}]
      ],
      markdown: {
          lineNumbers: true
      },
      themeConfig: {
          nav: [
  			{text: "首页", link: "/"},
  			{text: "碎碎念", link: "/life/"},
  			{text: "PAT", link: "/pat/basic/"},
              {text: "剑指offer", link: "/offer/"},
              {text: "LeeCode", link: "/leeCode/"},
              {text: "专栏", link: "/column/"},
              {text: "时光轴", link: "/timeaxle/"}
  		],
          sidebar: {
              "/life/": [
                  "",
                  "魔都折叠",
                  "莎翁的智慧"
              ],
              "/pat/basic/": [
                  "",
                  "1001",
                  "1002"
              ],
              "/timeaxle/": ["","",""]
          }
  
      }
  }
