PowerShell Invoke-WebRequest how to configure the selection of a request option in one scenario
Question: How to implement the choice of an action option in one scenario? Is it possible to do this through a function and substitute only the necessary parameters when choosing an option?
There are remote devices that need to be backed up if necessary. There is a way to do this manually, after logging in, waiting for the GUI to fully load - it may take 5-10 minutes. I wrote a CURL authorization request - it works. Then I did not bother with the command line, because there is a need to dodge, there is no necessary functionality. I rewrote it to PowerShell.
Step 1. Request authorization
$ip = Read-Host "Enter the ip address"
$xmlauth = "<request method=""login"" request_id=""1"" username=""name"" password=""pass""/>"
$access = Invoke-WebRequest -Uri ("http://"+$ip+":4000/xap2") `
-Method Post `
-ContentType "text/xml" `
-Body $xmlauth
$sessionid = ([xml]$access.Content).response.session_id
Write-Host $access #example of output after successful authorization
<response username="name" session_id="123456789" request_id="1" access_lvl="2">
<status status="0" status_text="OK"/>
</response>
Write-Host $sessionid #this id is inserted in all subsequent requests
123456789
Step 2. Request to change the parameters
$xml3in = @"
<request method="set" request_id="2" session_id="$sessionid" return_events="false">
<data>
<ports>
<asi_input enable="false" _id="0"/>
<asi_input enable="true" _id="2"/>
<_all _id="8">
<plprep main_globid="2"/>
</_all>
</ports>
</data>
</request>
"@
$request3in = Invoke-WebRequest -Uri ("http://"+$ip+":4000/xap2") `
-Method Post `
-ContentType "text/xml" `
-Body $xml3in
$status = ([xml]$request3in.Content).response.status.status_text
Write-Host $request3in #Example output after successful execution
<response request_id="2">
<status status="0" status_text="OK"/>
</response>
Write-Host $status #An example of the output of the status text, you can also do it by number
OK
if ( $status -like 'ok' ) {
Write-Host "THE DEVICE IS SWITCHED WHERE IT IS NEEDED ($status)" -foregroundcolor Green
}
else {
Write-Host "SOMETHING WENT WRONG ($status)" -foregroundcolor Red
}
Step 3. Request to change the parameters (return to the initial state) The only difference is in the request body.
$xml1in = @"
<request method="set" request_id="3" session_id="$sessionid" return_events="false">
<data>
<ports>
<asi_input enable="true" _id="0"/>
<asi_input enable="false" _id="2"/>
<_all _id="8">
<plprep main_globid="0"/>
</_all>
</ports>
</data>
</request>

Solution
At the moment, this is the working design that has been achieved.
