Powershell：无法解析从 Invoke-RestMethod 返回的 json

Question

I try to parse a json string returned from an API call.

$Response = Invoke-RestMethod -Uri $URIValue -Method Post -Headers $Headers -Body $requestBody -ContentType 'application/json; charset=utf-8'

$Response #Returns: {"results":[{"tables":[{"rows":[{"[Quantity]":200}]}]}]}

Now that I try to parse it Response | ConvertFrom-Json Response | ConvertFrom-Json I get the following error: ConvertFrom-Json: Conversion from JSON failed with error: Unexpected character encountered while parsing value: . Path '', line 0, position 0. ConvertFrom-Json: Conversion from JSON failed with error: Unexpected character encountered while parsing value: . Path '', line 0, position 0.

What am I doing wrong?

Answer 1

The actual solution:

$Response.Substring(1) | ConvertFrom-Json
