在Axios NuxtJS 配置之后，我在我的服务器上创建了一个这样的代理配置nuxt.config.js：

  proxy: {
    '/api/': {
      target: 'https://myapidomain.com/',
      pathRewrite: { '^/api/': '' },
      changeOrigin: true
    }
  }

此配置在dev环境中完美运行，服务器端渲染和客户端渲染。这是我们用来创建 api 包装器的代码api.js：

export default (context, inject) => {
  inject('api', {
    getPageForSlug: (slugRoute) => {
      return context.$axios.$get(`/api/pageForSlug?routeName=${slugRoute}`)
    },
  })
}

然后从任何 vue 类：

const response = await app.$api.getPageForSlug(params.slug_route)

唯一的问题是从zeit now部署中调用此代码。客户端工作正常，但服务器端返回此错误：

如何使服务器端 API 请求适用于所有环境？

这可以使用Vercel 文件rewrite中的 a 来实现。now.json无需破解。

{
  "version": 2,
  "builds": [
    {
      "src": "nuxt.config.js",
      "use": "@nuxtjs/vercel-builder",
      "config": {}
    }
  ],
  "rewrites": [
    {
      "source": "/api/:match*",
      "destination": "https://myapidomain.com/:match*"
    }
  ]
}

你准备好迎接终极黑客了吗？

这实际上是一个普遍的问题。调用时zeit now，服务器实际上并没有得到支撑。因此，您需要自己做。

我唯一一次遇到需要这样做的时候，我用express来解决它。一个快速而肮脏的解决方案是创建另一个脚本 ( proxy.js)，并具有如下内容：

import express from 'express'
import proxy from 'express-http-proxy'
const app = express()
app.use('/', proxy(`https://myapidomain.com`))
export default app

这只是为您的 API 设置反向代理。

从那里，在您的 zeit 配置中，找到您的builds密钥（如果有），并将其替换为：

"builds": [
    { "use": "@now/next", "src": "package.json" },
    { "use": "@now/node", "src": "proxy.js" }
]

proxy.js当您使用构建时，这将支持并执行zeit now。

请注意，这确实意味着您需要让主机proxy.js匹配“正常”主机。如果您知道配置文件的格式（您应该知道），则可以导入并解析它以获得一个事实来源。

让我知道这是否有效。
