如何将特定文件的内容类型更改为 application/json？

Question

对于 Matrix 家庭服务器（在 Modular.im 上），您需要有 2 个文件：

1. domain.tld/.well-known/matrix/server
2. domain.tld/.well-known/matrix/client

...它们还需要application/json代替 firebase 的默认值application/octet-stream。我该如何改变？

当前firebase.json的无效解决方案来自此答案。

$ cat firebase.json 
{
  "hosting": {
    "public": "public",
    "ignore": [
      "firebase.json",
      "**/.*",
      "**/node_modules/**"
    ],
    "rewrites": [
      {

        "source": "/.well-known/matrix/server",
        "destination": "/.well-known/matrix/server",
        "content-type": "application/json",
        "code":200
      },
      {

        "source": "/.well-known/matrix/client",
        "destination": "/.well-known/matrix/client",
        "content-type": "application/json",
        "code":200
      }
   ]
  }
}
$ firebase deploy

=== Deploying to 'dh'...

你遇到的答案是不正确的。您需要指定自定义标题：

{
  "hosting": {
    "headers": [
      {
        "source": "/.well-known/matrix/*",
        "headers": [
          {"key": "Content-Type", "value": "application/json"}
        ]
      }
    ]
  }
}
