意外数组字符串的转换 [英] Unexpected array to string conversion

问题描述

我试图用显示之前收拾我的数据为对象的ConvertTo JSON的。下面的测试案例展示完美我是如何处理的数据，什么问题时：

I'm trying to pack my data into objects before displaying them with ConvertTo-Json. The test case below shows perfectly how I'm dealing with data and what problem occurs:

$array = @("a","b","c")
$data = @{"sub" = @{"sub-sub" = $array}}
$output = @{"root" = $data}
ConvertTo-Json -InputObject $data
ConvertTo-Json -InputObject $output

输出（由专人为清楚起见格式化）：

Output (formatted by hand for clarity):

          { "sub": { "sub-sub": [ "a", "b", "c" ] }}
{ "root": { "sub": { "sub-sub": "a b c" } }}

有什么办法来分配 $数据到 $输出没有这个奇怪的隐式转换？

Is there any way to assign $data to $output without this weird implicit casting?

推荐答案

由于在评论中提到的，的ConvertTo JSON的将尝试的平展的对象结构超出最大嵌套级别，或深度的，通过将它找到的任何对象超出深度为一个字符串。

As mentioned in the comments, ConvertTo-Json will try to flatten the object structure beyond a maximum nesting level, or depth, by converting whatever object it finds beyond that depth to a string.

默认深度为2，但你可以指定它应该去更深的深度参数：

The default depth is 2, but you can specify that it should go deeper with the Depth parameter:

PS C:\> @{root=@{level1=@{level2=@("level3-1","level3-2")}}}|ConvertTo-Json
{
    "root":  {
        "level1":  {
            "level2":  "level3-1 level3-2"
        }
    }
}
PS C:\> @{root=@{level1=@{level2=@("level3-1","level3-2")}}}|ConvertTo-Json -Depth 3
{
    "root":  {
        "level1":  {
            "level2":  [
                "level3-1",
                "level3-2"
            ]
        }
    }
}
