带参数的CreateStackInput（）

Question

I am converting from using aws cli commands to use the aws go api. Having some trouble figuring out how to pass parameters into the CreateStackInput call.

Here is the commandline I'm attempting to replicate with the aws api:

aws cloudformation create-stack         --stack-name "poc1841"         --template-url "https://s3-us-west-2.amazonaws.com/<path_removed>/cfn-cl-template.json"         --parameters file:///params/poc1841.json

The params file looks like:

[
   {
"ParameterKey":"CNAMEPrefix",
"ParameterValue":"poc1841001"
}]

Here's the api call I'm using:

input := &cloudformation.CreateStackInput{
        TemplateBody: aws.String(templateBody),
        StackName: aws.String(stackName),
        OnFailure: aws.String("ROLLBACK"),
        TimeoutInMinutes: &timeoutInMins }

The CreateStackInput does have a Parameters attribute of type Parameters. What special handling of the params json file do I need to pass these values into the Parameter field?
