Question

我的输入是：

    public MainWindow()
    {
        InitializeComponent();
    }

    private void Button1_Click(object sender, RoutedEventArgs e)
    {
        Button button1 = sender as Button;
        button1.Content = "Something";
    }

    private void Button2_Click(object sender, RoutedEventArgs e)
    {
        Button1.Content = "Something2";
    }

我想要的输出是：

input = [
  {
    x = "X1"
    y = "Y1"
  },
  {
    x = "X2"
    y = "Y2"
  },
  {
    x = "X3"
    y = "Y3"
  },
]

如何在Terraform中实现？

Answer 1

为此，我能够在terraform中使用flatten()函数：

flatten([
  for a_map in var.input : [
    { val = a_map.x, description = "This is a value of X" },
    { val = a_map.y, description = "This is a value of Y" },
  ]
])

此方法的一个优点是它将保持值的顺序。

所以输出将是：

[
  {
    "description" = "This is a value of X"
    "val" = "X1"
  },
  {
    "description" = "This is a value of Y"
    "val" = "Y1"
  },
  {
    "description" = "This is a value of X"
    "val" = "X2"
  },
  {
    "description" = "This is a value of Y"
    "val" = "Y2"
  },
  {
    "description" = "This is a value of X"
    "val" = "X3"
  },
  {
    "description" = "This is a value of Y"
    "val" = "Y3"
  },
]

Answer 2

以下产生这样的输出：



variable "input" {

  default = [
    {
      x = "X1"
      y = "Y1"
    },
    {
      x = "X2"
      y = "Y2"
    },
    {
      x = "X3"
      y = "Y3"
    },
  ]

}



locals  {
  part1 = [for v in var.input:
      {
        "val" = v.x,
        "description" = "This is a value of X"
      }]
      
  part2 = [for v in var.input:
      {
        "val" = v.y,
        "description" = "This is a value of Y"
      }]      
}



output "output" {

  value = concat(local.part1, local.part2)

}

我的测试输出：

utput = [
  {
    "description" = "This is a value of X"
    "val" = "X1"
  },
  {
    "description" = "This is a value of X"
    "val" = "X2"
  },
  {
    "description" = "This is a value of X"
    "val" = "X3"
  },
  {
    "description" = "This is a value of Y"
    "val" = "Y1"
  },
  {
    "description" = "This is a value of Y"
    "val" = "Y2"
  },
  {
    "description" = "This is a value of Y"
    "val" = "Y3"
  },
]
