Explore the $o_response variable to check the return values. Call it by: fcn-check-site -UNAME username -UPASS password -URI secureURL
function fcn-check-site {
Param (
[ Parameter( Mandatory = $true ) ]
$UNAME,
[ Parameter( Mandatory = $true ) ]
$UPASS,
[ Parameter( Mandatory = $true ) ]
$URI
)
Begin {
$s_username = $UNAME
$s_password = $UPASS
$s_URI = $URI
}
Process {
try {
# Create a Web Request object. This object can have different properties/payloads attached to be sent to the URL in question.
$o_webrequest = [System.Net.WebRequest]::Create( $s_URI )
$o_secpasswd = $s_password | ConvertTo-SecureString -AsPlainText -Force -ErrorAction Stop
$o_mycreds = New-Object System.Management.Automation.PSCredential ($s_username,$o_secpasswd) -ErrorAction Stop
# The connection test is to check if the login returns a 'good/ok/200' value. Hence, nothing is POST-ed. Only GET-ted.
$o_webrequest.Method = 'GET'
$o_webrequest.Credentials = $o_mycreds
# 30 second timeout on the request to be made.
$o_webrequest.Timeout = 30000
# This C# code makes sure that SSL certificate checks are skipped.
try {
# This erroractionpreference variable will STOP the compilaton errors thrown by C#.
$ErrorActionPreference = 'Stop'
add-type -ErrorAction Stop -TypeDefinition #"
