Giving UrLs as value to input parameters in a powershell script

PowerShell Help
1

Hi, this is my following code with two input parameters,

param(
    [parameter(Mandatory=$true)]
    [ValidateNotNullOrEmpty()]
    [string]
    $textFilePath,
    [parameter(Mandatory=$true)]
    [ValidateNotNullOrEmpty()]
    [string]
    $searchDirectory
)

foreach($FileName in [System.IO.File]::ReadLines($textFilePath)) {
    # if the file could be found
    if(Get-ChildItem -Path $searchDirectory -Filter $Filename -Recurse) {
        return 1 # exit early from the script here
    }
}
return 0 # return is not needed here

i want to input url for the second input parameter, but error occurs as below. Please let me know, what is missing in my code. I have following files listed in the LibraryChecker.SharedEnvironmentLog.txt (specified in the URL)

Middleware.lo.dll
temp.txt

Thanks.

textFilePath: https://github.com/MW/tfsbuildrelease/blob/master/LibraryChecker.SharedEnvironmentLog.txt
searchDirectory: D:\

Before we proceed … When you post code, sample data, console output or error messages please format it as code using the preformatted text button ( </> ). Simply place your cursor on an empty line, click the button and paste your code.

Thanks in advance

Please go back, edit your question and fix your formatting.

I have formatted. Thanks

You cannot read a file directly from the internet like this:

[System.IO.File]::ReadLines($textFilePath)

You have to download the file first.

Can you please help me with code to download the file and then read from it?

Thanks

    [ValidateNotNullOrEmpty()]
    [string]
    $searchDirectory
)


#if(-not (Test-Path -Path $searchDirectory)){
    #Write-Host "The source folder specified is not valid"
#return

#$SourceFilePath = https://github.bnsf.com/raw/MW/tfsbuildrelease/master/LibraryChecker.SharedEnvironmentLog.txt
#$DestFilePath = c:\LibraryChecker.SharedEnvironmentLog.txt

#Download the file
Invoke-WebRequest -Uri $SourceFilePath -OutFile $DestFilePath

# Get-Content -Path $textFilePath

foreach($FileName in [System.IO.File]::ReadLines($DestFilePath)) {

You should learn how to debug your own code. Please keep in mind we cannot see your screen and we cannot read your mind.

Exception calling “ReadLines” with “1” argument(s): “Empty path name is not legal.
Parameter name: path”

It looks like you did not provide a value for the parameter -DestFilePath
