Question

所以从我读过的所有东西，全局安装了firebase-tools，我的Windows命令提示符在包含我的项目的文件夹中打开，一个正在运行的firebase.json文件（在firebase部署中工作正常）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

但是对于database.json，我收到以下错误：

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

database.json包含以下内容：

{
  "catalogue": {
    "csi": {
      "descriptionRoute": "csi",
      "fileName": "ctk%20Currency%20Strength%20Indicator.algo",

      "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"
    },
    "csh": {
      "descriptionRoute": "csh",
      "fileName": "ctk%20Currency%20Strength%20Heatmap.algo",
      "id": 2,
      "imageUrl": "/images/csh.png",
      "isFeatured": true,
      "name": "Currency Strength Heatmap",

    },

    },
    "atrsl": {
      "descriptionRoute": "atrsl",

      "id": 4,
      "imageUrl": "/images/atrsl.png",
      "isFeatured": false,

      "shortDescription": "Displays ATR and stop loss values based on your requirements.",
      "type": "indicator"
    },
    "ha": {
      "descriptionRoute": "ha",
      "fileName": "ctk%20Heken%20Ashi.algo",
      "id": 5,
      "imageUrl": "/images/ha.png",
      "isFeatured": false,
      "name": "Heiken Ashi",
      "shortDescription": "Paints Heiken Ashi candles on the host chart.",
      "type": "indicator"
    },
    "hama": {
      "descriptionRoute": "hama",
      "fileName": "ctk%20Heken%20Ashi%20Moving%20Average.algo",
      "id": 6,
      "imageUrl": "/images/hama.png",
      "isFeatured": false,
      "name": "Heiken Ashi Moving Average",
      "shortDescription": "Paints Heiken Ashi Moving Average on the host chart.",
      "type": "indicator"
    },
    "psl": {
      "descriptionRoute": "psl",
      "fileName": "ctk%20Psych%20Levels%20.algo",
      "id": 7,
      "imageUrl": "/images/psl.png",
      "isFeatured": false,
      "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，我用Google搜索的一切表明它很好，但错误就是我能得到的。

所以我跑了

firebase database:get / > database2.json

具有以下结果：

{
  "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"
    }
  ]
}

然后不知不觉地跑了

firebase数据库：set / database2.json

并得到了同样的错误。我很难过，如果无法上传下载数据的格式，我需要哪种格式？

Answer 1

我解决了这个问题，正如Bob Snyder暗示问题是文件的编码。

我最初是从Visual Studio 2017中的JSON文件模板创建的。要检查编码，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并运行了原始命令：

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人，请确保您的JSON文件的编码为UTF-8。

使用数据库的格式正确：使用firebase-tools
