Firebase托管多个子域到带有一个项目的应用程序目录

我目前有一个应用程序部署到Firebase托管,其结构如下:

public/
    appSub1/
        index.html
    appSub2
        index.html
    index.html

appSub1.mysite.com/ -> app.firebaseapp.com/
appSub2.mysite.com/ -> app.firebaseapp.com/

我正在尝试配置重定向以将子域与正确的应用程序子文件夹正确关联,以便

appSub1.mysite.com/ -> app.firebaseapp.com/appSub1/
appSub2.mysite.com/ -> app.firebaseapp.com/appSub2/

如果我手动添加子路径,应用程序仍然正确显示,但不能没有它们。所以要 appSub1.mysite.com/ 只不过是一张白纸,但是 appSub1.mysite.com/appSub1/ index.html

这是我当前的主机配置 firebase.json

"hosting": {
    "public": "public",
    "ignore": [
      "firebase.json",
      "**/.*",
      "**/node_modules/**"
    ],
    "rewrites": [
      {
        "source": "appSub1.mysite.com/**",
        "destination": "/appSub1/**",
        "type": 301
      },
      {
        "source": "appSub2.mysite.com/**",
        "destination": "/appSub2/**",
        "type": 301
      }
    ]
  },
