Mixing
Powershell $Credential object to prevent the need for user interaction
1
Hello StackOverflow!,
I am trying to create a new object that I can pass the un/pwd too so that i don't require user interaction when speaking to the rest API i am working with.
Microsoft have a handy example (Example 7) of this found at: https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.security/get-credential?view=powershell-6
However when using this method I receive the following:
New-Object : Cannot find an overload for "PSCredential" and the argument
count:
"2".
At line:17 char:15
+ ... redential = New-Object -TypeName

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidArgument: (:) [Invoke-RestMethod],
ParameterB
indingException
+ FullyQualifiedErrorId :
PositionalParameterNotFound,Microsoft.PowerShell.Com
mands.InvokeRestMethodCommand
Just so that you can verify my code, its basically the same as the Microsoft example:
$Uri = 'A url to a rest api'
$User = "A Username"
$PWD = "A Password"
$Credential = New-Object -TypeName
System.Management.Automation.PSCredential -ArgumentList $User, $PWD
#Invokes rest get request to rabbitmq uri
Invoke-RestMethod -Method Get -Uri $uri $Credential
With the error received i imagine i'm not passing the New-Object command something it is expecting ?
Any help is appreciated.
Thanks,

As the error message says. There is no "PSCredential" constructor that accepts two arguments of typeString(docs). The only constructor that accepts 2 arguments expectsStringandSecureString. So your underlying question is: How do I convert a String to a SecureString.

Thanks for this, @TobyU mentioned this as well and can see he included the same conversion that Microsoft used on their page (doh!), I am now converting the string to a SecureString using this method but am still hitting a brick wall when passing this to the Invoke-RestMethod command.

What happens when you explicitly state the parameter name, i.e.-Credential $Credential?

You need to make a SecureString out of the password like:
$User = "A Username"
$PWD = ConvertTo-SecureString -String "A Password" -AsPlainText -Force
$Credential = New-Object System.Management.Automation.PSCredential($User,$PWD)
Invoke-RestMethod -Method Get -Uri $uri -Credential $Credential

As the error message says. There is no "PSCredential" constructor that accepts two arguments of type
String(docs). The only constructor that accepts 2 arguments expectsStringandSecureString. So your underlying question is: How do I convert a String to a SecureString.– Tomalak

Thanks for this, @TobyU mentioned this as well and can see he included the same conversion that Microsoft used on their page (doh!), I am now converting the string to a SecureString using this method but am still hitting a brick wall when passing this to the Invoke-RestMethod command.

What happens when you explicitly state the parameter name, i.e.
-Credential $Credential?– Tomalak
