Class ReverseProxySetupMonitor

java.lang.Object

hudson.model.AbstractModelObject

hudson.model.AdministrativeMonitor

hudson.diagnosis.ReverseProxySetupMonitor

All Implemented Interfaces:

ExtensionPoint, ModelObject, SearchableModelObject, SearchItem, org.kohsuke.stapler.StaplerProxy

@Extension
@Symbol("reverseProxy")
public class ReverseProxySetupMonitor
extends AdministrativeMonitor

Looks out for a broken reverse proxy setup that doesn't rewrite the location header correctly.

Have the JavaScript make an AJAX call, to which we respond with 302 redirect. If the reverse proxy is done correctly, this will be handled by web methods, but otherwise we'll report that as an error. Unfortunately, XmlHttpRequest doesn't expose properties that allow the client-side JavaScript to learn the details of the failure, so we have to make do with limited information.

Method Details

isActivated

public boolean isActivated()

Description copied from class: AdministrativeMonitor

Returns true if this monitor is activated and wants to produce a warning message.

This method is called from the HTML rendering thread, so it should run efficiently.

Specified by:

isActivated in class AdministrativeMonitor

doTest

@Restricted(org.kohsuke.accmod.restrictions.DoNotUse.class)
@RestrictedSince("2.235")
public org.kohsuke.stapler.HttpResponse doTest(org.kohsuke.stapler.StaplerRequest request,
 @QueryParameter
 boolean testWithContext)

getTestForReverseProxySetup

@Restricted(org.kohsuke.accmod.restrictions.DoNotUse.class)
@RestrictedSince("2.235")
@StaplerDispatchable
public void getTestForReverseProxySetup(String rest)

getRequiredPermission

public Permission getRequiredPermission()

Description copied from class: AdministrativeMonitor

Required permission to view this admin monitor. By default Jenkins.ADMINISTER, but Jenkins.SYSTEM_READ or Jenkins.MANAGE are also supported.

Changing this permission check to return Jenkins.SYSTEM_READ will make the active administrative monitor appear on manage.jelly and on the globally visible AdministrativeMonitorsDecorator to users without Administer permission. AdministrativeMonitor.doDisable(StaplerRequest, StaplerResponse) will still always require Administer permission.

This method only allows for a single permission to be returned. If more complex permission checks are required, override AdministrativeMonitor.checkRequiredPermission() and AdministrativeMonitor.hasRequiredPermission() instead.

Implementers need to ensure that doAct and other web methods perform necessary permission checks: Users with System Read permissions are expected to be limited to read-only access. Form UI elements that change system state, e.g. toggling a feature on or off, need to be hidden from users lacking Administer permission.

Overrides:

getRequiredPermission in class AdministrativeMonitor

doAct

@Restricted(org.kohsuke.accmod.restrictions.DoNotUse.class)
@RestrictedSince("2.235")
public org.kohsuke.stapler.HttpResponse doAct(@QueryParameter
 String no)
                                       throws IOException

Depending on whether the user said "yes" or "no", send him to the right place.

Throws:

IOException

getDisplayName

public String getDisplayName()

Specified by:

getDisplayName in interface ModelObject

Overrides:

getDisplayName in class AdministrativeMonitor
