Inconsistent behavior from Invoke-RestMethod from Windows Powershell to Powershell Core #6002
Description
Steps to reproduce
This same code, works in Powershell in Windows, where in Linux doesn't.
$contentType = "octet-stream"
$headers = @{"foo"="bar"}
Invoke-RestMethod -method post "http://foo/bar" -Headers $headers -ContentType $contentType -infile $chunkFile
Expected behavior
Actual behavior
The format of value 'octet-stream' is invalid. However, it does allows: "application/octect-stream"

As far as I can tell, a mimetype consists of a type/subtype. Seems like we have 3 options here:

Strict header validation is now default in PS core. This applies to any RFC defined header supplied to
-Headersor-ContentType. One can bypass strict header validation with the-SkipHeaderValidationparameter.https://github.com/PowerShell/PowerShell/blob/master/docs/BREAKINGCHANGES.md#changes-to-web-cmdlets

Actually... there seems to be some odd behavior here. -SkipHeaderValidation doesn't seem to work when
-InFileis used. This is a bug. I'll have to look into it.markekraus commentedon Jan 24, 2018
After investigating,
-SkipHeaderValidationis not being applied at all to-ContentType. I should have a PR to fix this tomorrow or later today. I have the fix code, just need to write tests.
