要检查参数是否由调用者传入,请检查 $PSBoundParameters
自动变量:
To check whether a parameter was either passed in by the caller or not, inspect the $PSBoundParameters
automatic variable:
if($PSBoundParameters.ContainsKey('AddHash')) {
# switch parameter was explicitly passed by the caller
# grab its value
$requestparams.Code = $AddHash.IsPresent
}
else {
# parameter was absent from the invocation, don't add it to the request
}
如果您要传递多个开关参数,请遍历 $PSBoundParameters
中的条目并测试每个值的类型:
If you have multiple switch parameters that you want to pass through, iterate over the entries in $PSBoundParameters
and test the type of each value:
param(
[switch]$AddHash,
[switch]$AddOtherStuff,
[switch]$Yolo
)
$requestParams = @{ header = 'value' }
$PSBoundParameters.GetEnumerator() |ForEach-Object {
$value = $_.Value
if($value -is [switch]){
$value = $value.IsPresent
}
$requestParams[$_.Key] = $value
}
