JSON结构无法在转换往返中幸存

Question

This command:

ConvertTo-Json (ConvertFrom-Json '{ "abc": [ [1, 2, 3], 4, [5, 6, 7] ] }')

returns:

{ "abc":  [ [ 1, 2, 3 ], 4, [ 5, 6, 7 ] ] }

However, the following (the same value at a deeper level):

ConvertTo-Json (ConvertFrom-Json '{ "abc": { "abc": [ [ 1, 2, 3 ], 4, [5, 6, 7] ] } }')

returns:

{ "abc":  { "abc":  [ "1 2 3", 4, "5 6 7" ] } }

Is this a bug?

Ideally, I'd like to find out what PowerShell value to pass to ConvertTo-Json in order to produce the JSON in the 2nd example, ie:

'{ "abc": { "abc": [ [ 1, 2, 3 ], 4, [5, 6, 7] ] } }'

I usually use ConvertFrom-Json to find out such values.

Answer 1

Passing -Depth 3 to ConvertTo-Json solves the problem:

ConvertTo-Json -Compress -Depth 3 (ConvertFrom-Json '{ "abc": { "abc": [ [ 1, 2, 3 ], 4, [5, 6, 7] ] } }')

produces:

{"abc":{"abc":[[1,2,3],4,[5,6,7]]}}
