Download XML via HTTPS

Question

I'm trying to download XML file (Jenkins config.xml history file) from Jenkins HTTPS server. I searched here and elsewhere but still cannot find the way to get it working.

$url = "https://<server-path>/configOutput?type=xml&timestamp=2018-02-23_13-09-02"

$file = "d:\file.xml"
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Ssl3
$wc = New-Object System.Net.WebClient
$wc.Credentials = Get-Credential
$wc.DownloadFile($url, $file)

After supplying credentials to prompt I'm getting this error:

Exception calling "DownloadFile" with "2" argument(s): "The underlying connection
was closed: An unexpected error occurred on a receive."
At D:\ps\jenkins-config\get_xml.ps1:7 char:1
+ $wc.DownloadFile($url,$file)
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : WebException

I don't see anything wrong with your code (other than SSLv3 being broken), so the issue is probably with the network or the server. Check the Jenkins logs. — Ansgar Wiechers
Ok, so it seems that the problem is with log in. Jenkins expects logged in user and even though I supply correct credentials the information about successful login is not saved anywhere (session, cookie, ..) therefore I am still getting 403. So the problem here is to first log in (in PS script), save this info and then request the page from URL. Is this even possible? — himi

I'd use the Invoke-WebRequest method:

Invoke-WebRequest -Uri $url -ContentType 'application/xml' -OutFile $file -Credential $(Get-Credential) -Timeout 60

I've seen "configOutput" for job history care-of the JobConfigHistory plug-in. I've never seen it to get Jenkin's config file (the one in JENKINS_HOME). If you're trying to control a job's config, double check your URL.
