Class AuthenticatedHttpEventProcessor

java.lang.Object

org.alfresco.bm.event.AbstractEventProcessor

org.alfresco.bm.http.AuthenticatedHttpEventProcessor

All Implemented Interfaces:

EventProcessor, org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanNameAware

public abstract class AuthenticatedHttpEventProcessor
extends AbstractEventProcessor

A base class used for EventProcessors that makes use of HTTP-calls that should be done when authenticated against Alfresco. Subclasses can just do the HTTP-call(s) without having to worry about authentication. Use #executeHttpMethodAuthenticated(HttpRequestBase, String) instead of using HttpClient manually or #executeHttpMethodAsAdmin(HttpRequestBase) to run as Alfresco Administrator.

Supports both BASIC Authentication (default) and Ticket-based authentication. In case ticket-based authentication is used, the ticket value is stored on the user data-provider and a new ticket is fetched transparantly when the ticket is expired.

Constructor Detail

AuthenticatedHttpEventProcessor

public AuthenticatedHttpEventProcessor(org.alfresco.http.HttpClientProvider httpClientProvider,
                               org.alfresco.http.AuthenticationDetailsProvider authDetailProvider,
                               String baseUrl)

Parameters:

httpClientProvider - provider class for http-client

authDetailProvider - provider for authentication details

baseUrl - the URL to append to

Method Detail

setTicketBasedAuthentication

public void setTicketBasedAuthentication(boolean ticketBasedAuthentication)

Enable ticket-based authentication. If set to false, BASIC Authentication will be used instead. Defaults to false.

Parameters:

ticketBasedAuthentication - whether or not to use ticket for authentication

getHttpProvider

public org.alfresco.http.HttpClientProvider getHttpProvider()

Returns:

the HttpClientProvider used by this class.

getAuthDetailProvider

public org.alfresco.http.AuthenticationDetailsProvider getAuthDetailProvider()

Returns:

the AuthenticationDetailsProvider used by this class.

getFullUrlForPath

public String getFullUrlForPath(String path)

Parameters:

path - relative path of the URL from alfresco host.

Returns:

full URL including hostname and port for the given path.

executeHttpMethodAsUser

protected <T> T executeHttpMethodAsUser(org.apache.http.client.methods.HttpRequestBase request,
                            String username,
                            org.alfresco.http.HttpRequestCallback<T> callback)

Execute the given method, authenticated as the given user. Automatically closes the response-stream to release the connection. If response should be extracted, this should be done in the HttpRequestCallback.

Parameters:

request - request to execute

username - name of user to authenticate as

callback - called after http-call is executed. When callback returns, the response stream is closed, so all respose-related operations should be done in the callback. Can be null.

Returns:

whatever the callback dictates

executeHttpMethodAsAdmin

protected <T> T executeHttpMethodAsAdmin(org.apache.http.client.methods.HttpRequestBase request,
                             org.alfresco.http.HttpRequestCallback<T> callback)

Execute the given method, authenticated as the Alfresco Administrator.

Parameters:

request - request to execute

callback - called after http-call is executed. When callback returns, the response stream is closed, so all respose-related operations should be done in the callback. Can be null.

Returns:

whatever the callback dictates

releaseResources

protected void releaseResources(org.apache.http.client.methods.HttpRequestBase request,
                    org.apache.http.HttpResponse response)

Release resources associated with an HTTP request. This method handles exceptions internall so no try-catch is required.

Parameters:

request - the HTTP request that might have open resources (null allowed)
