因此，从我读过的所有内容来看，在全局安装了 firebase-tools 后，我的 Windows 命令提示符在包含我的项目的文件夹中打开，一个工作的 firebase.json 文件（在该 firebase deploy 中工作正常）我应该能够运行以下命令覆盖我的firebase数据库的全部内容：

firebase database:set / database.json

但是使用 database.json 我得到以下错误：

Error: HTTP Error: 400, Invalid data; couldn't parse JSON object, array, or value.

database.json 包含以下内容：

      "isFeatured": false,
      "name": "Heiken Ashi Moving Average",
      "shortDescription": "Paints Heiken Ashi Moving Average on the host chart.",
      "type": "indicator"
    },
    "psl": {

      "name": "Psych Levels",
      "shortDescription": "Draws lines at psychological levels that often form string Support and Resistance",
      "type": "indicator"
    }
  }
}

我看不出有什么问题，我在谷歌上搜索的所有内容都表明它很好，但我能得到的只是错误。

所以我跑了

firebase database:get / > database2.json

结果如下：

{
  "catalogue": [
    null,
    {
      "descriptionRoute": "csi",
      "fileName": "ctk%20Currency%20Strength%20Indicator.algo",
      "id": 1,
      "imageUrl": "/images/csi.png",
      "isFeatured": true,
      "name": "Currency Strength Indicator",
      "shortDescription": "Plots the relative strength of 8 major currencies as a line chart",
      "type": "indicator"
    },
    {
      "descriptionRoute": "csh",
      "fileName": "ctk%20Currency%20Strength%20Heatmap.algo",
      "id": 2,
      "imageUrl": "/images/csh.png",
      "isFeatured": true,
      "name": "Currency Strength Heatmap",
      "shortDescription": "Plots the relative strength of 8 major currencies as a heatmap",
      "type": "indicator"
    },
    {
      "descriptionRoute": "ffc",
      "fileName": "ctk%20FF%20Calendar.algo",
      "id": 3,
      "imageUrl": "/images/ffc.png",
      "isFeatured": true,
      "name": "Forex Factory Calendar",
      "shortDescription": "Lists upcoming events from the Forex Factory RSS feed",
      "type": "indicator"
    },
    {
      "descriptionRoute": "atrsl",
      "fileName": "ctk%20ATR%20Stop%20Loss%20Indicator.algo",
      "id": 4,
      "imageUrl": "/images/atrsl.png",
      "isFeatured": false,
      "name": "ATR Stop Loss Indicator",
      "shortDescription": "Displays ATR and stop loss values based on your requirements.",
      "type": "indicator"
    }
  ]
}

然后立马跑了

firebase 数据库：设置/database2.json

并得到同样的错误。我很困惑，如果下载数据的格式无法上传，我需要什么格式？

我解决了这个问题，正如 Bob Snyder 暗示的那样，问题在于文件的编码。

我最初从 Visual Studio 2017 中的 JSON 文件模板创建文件。为了检查编码，我在 NotePad++ 中打开它，它显示编码为 UTF-8-BOM。我在 NP++ 中将编码更改为 UTF-8 并运行原始命令：

firebase database:set / database.json

它第一次工作，我的数据库被覆盖了。

因此，对于遇到此问题的其他任何人，请确保您的 JSON 文件的编码是 UTF-8。
