如何根据特定目标设置 Firebase 托管标头？

Question

使用 Firebase 托管，我可以使用firebase.json文件设置标头。

是否可以根据使用的 Firebase project / target设置标头？

例如，有以下目标：

{
  "projects": {
    "default": "myproject",
    "staging": "myproject-staging"
  },
  "targets": {
    "myproject": {
      "hosting": {
        "site": [
          "the-site"
        ]
      }
    },
    "myproject-staging": {
      "hosting": {
        "site": [
          "the-site"
        ]
      }
    }
  }
}

如何根据目标设置在firebase.json配置的一些标头？

{
  "hosting": {
    "target": "site",
    "public": "...",
    "rewrites": [
      ...
    ],
    "headers": [
      {
        "source": "**",
        "headers": [
          {
            "key": "X-Content-Type-Options",
            "value": "nosniff"
          },
          {
            "key": "My-Custom-Header",   <---- This should only be applied if the target is staging (or it's value should be different for the default target)
            "value": "DENY"
          },
        ]
      }
    ]
  }
}

所以当我做

• firebase deploy --project default我希望My-Custom-Header具有值ALLOW
• firebase deploy --project staging我希望My-Custom-Header具有值DENY 。
