POST request with Powershell 2.0 using cURL

Question

Scenario

Among other things, Powershell 2.0 doesn\'t have the useful cmdlet Invoke-RestMethod.

I can\'t upgrade to version 3 and most examples I\'ve found

Answer 1

Note that the question is about the curl.exe external program, not about PowerShell's Invoke-WebRequest cmdlet (which, unfortunately, is aliased to curl in later PowerShell versions, preempting calls to the external program unless the .exe extension is explicitly specified (curl.exe ...).

Unfortunately and unexpectedly, you have to \-escape embedded " instances in a string you pass as an argument to an external program.

Therefore, even though:

'{"Id":5,"Email":"test@com","DataFields":null,"Status":0}'

should work, it doesn't, due to a long-standing bug; instead, you must use:

'{\"Id\":5,\"Email\":\"test@com\",\"DataFields\":null,\"Status\":0}'
