在 TOML 文件上创建新行

问题描述

我正在尝试理解 TOML 结构和

[[servers]]
ip = "10.0.0.1"
role = "frontend"
[[servers]]
ip = "10.0.0.2"
role = "backend"

developer = "developer_name"

如果我解析上面的得到json

{
  "servers": [
    {
      "ip": "10.0.0.1","role": "frontend"
    },{
      "developer": "developer_name","ip": "10.0.0.2","role": "backend"
    }
  ]
}

如您所见，开发人员嵌套在第二个对象中。但我需要 root 中的开发人员。

我使用本网站来验证 TOML TOML Parser

预期结果

{
      "servers": [
        {
          "ip": "10.0.0.1","role": "frontend"
        },{
          
          "ip": "10.0.0.2","role": "backend"
        }
      ],"developer": "developer_name"
    }

解决方法

Toml 表中的键/值对不保证按任何特定顺序排列。 在根表中获取 'developer' 的方法是将它放在表的 'servers' 数组之前：

developer = "developer_name"
[[servers]]
ip = "10.0.0.1"
role = "frontend"
[[servers]]
ip = "10.0.0.2"
role = "backend"

这将导致这个 Json 结构：

{
    "developer": "developer_name","servers": [
    {
        "ip": "10.0.0.1","role": "frontend"
    },{
        "ip": "10.0.0.2","role": "backend"
    }]
}

这个小例子也可以用内联数组格式化：

servers = [{ip = "10.0.0.1",role = "frontend"},{ip = "10.0.0.2",role = "backend"}]
developer = "developer_name"

这将导致相同的 Json 结构。
