firebase - Access-Control-Allow-Origin 添加到 firebase.json 但在文件响应 header 中缺失

Question

下面是我的简单的 firebase.json。如果我正确阅读文档，它应该用“Access-Control-Allow-Origin”标记所有文件。不幸的是，没有任何文件被标记，导致错误:

Imported resource from origin 'https://gaspush.firebaseapp.com' has been blocked from loading by Cross-Origin Resource Sharing policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

有人可以看一下并让我知道如何正确允许所有文件发送到所有端点吗？

{
  "firebase": "gaspush",
  "headers": [ {
    "source" : “**”,
    "headers" : [ {
      "key" : "Access-Control-Allow-Origin",
      "value" : "*"
    } ]
  } ],
  "public": ".",
  "ignore": [
    "firebase.json",
    "**/.*",
    "**/node_modules/**"
  ]
}

这可能不再与原来的问题相关，但我在新版本的 Firebase 中遇到了类似的问题。我不小心将 "headers" 部分放置在 "hosting" 键之外。

下面的代码片段对我有用。

"hosting": {
    "public": ".",
    "headers": [ {
        "source" : "**",
        "headers" : [{
          "key" : "Access-Control-Allow-Origin",
          "value" : "*"
        }]
    }]
  }
