firebase-hosting - 如何在 Firebase 托管 header 规则中定位域根

Question

我有一个使用自定义域的网络应用程序。此域具有映射到 151.101.1.195 和 151.101.65.195 的 A 记录。

一切正常，但是当我有 firebase.json 时:

{
  "hosting": {
    "public": "dist",
    "headers": [{
      "source": "**/*.html",
      "headers": [{
        "key": "Cache-Control",
        "value": "private, max-age=0, no-cache"
      }]
    }]
  }
}

当我访问 https://mycustomdomain.com 时，我仍然看到这样的响应 header :

accept-ranges:bytes
cache-control:max-age=3600
content-encoding:gzip
content-length:839
content-type:text/html; charset=utf-8
date:Wed, 27 Sep 2017 06:54:58 GMT
etag:"f0b36e6c2a348eb46d07907fea856e9a"
last-modified:Wed, 27 Sep 2017 06:53:07 GMT
server:nginx
status:200
strict-transport-security:max-age=31556926
vary:Accept-Encoding
via:1.1 varnish
x-cache:HIT
x-cache-hits:2
x-powered-by:Express
x-served-by:cache-bma7024-BMA
x-timer:S1506495298.256593,VS0,VE0

我希望缓存控制头被修改，但它不会改变。

如何更改域根的响应 header ？

Answer 1

对于任何人来说，我最终都是这样做的，它似乎有效:

{
  "hosting": {
    "public": "dist",
    "headers": [
      {
        "source": "/",
        "headers": [{
          "key": "Cache-Control",
          "value": "private, max-age=0, no-cache"
        }]
      },
      {
        "source": "**/*",
        "headers": [{
          "key": "Cache-Control",
          "value": "private, max-age=0, no-cache"
        }]
      },
      {
        "source": "**/*.js",
        "headers": [{
          "key": "Cache-Control",
          "value": "max-age=31536000"
        }]
      },
      {
        "source": "**/*.css",
        "headers": [{
          "key": "Cache-Control",
          "value": "max-age=31536000"
        }]
      },
      {
        "source": "**/*.jpg",
        "headers": [{
          "key": "Cache-Control",
          "value": "max-age=31536000"
        }]
      },
      {
        "source": "**/*.png",
        "headers": [{
          "key": "Cache-Control",
          "value": "max-age=31536000"
        }]
      }
    ],
    "rewrites": [
        { "source": "/api/1/mina", "function": "mydata" },
        { "source": "**", "destination": "/index.html" } 
      ]
  }
}

这也适用于函数。请注意，.js 文件也被积极缓存，因为我们使用缓存破坏 url。
