Interface RemoteAlfrescoTicketService

All Known Implementing Classes:

RemoteAlfrescoTicketServiceImpl

public interface RemoteAlfrescoTicketService

Service for working with a Remote Alfresco instance, which holds user credentials for the remote system via the RemoteCredentialsService, and handles ticket negotiation for you. Currently only Username+Password credentials, exchanged for a regular alf_ticket Alfresco Ticket are supported, but things like OAuth should be supportable too later. All Remote Systems must be registered with this service before use, supplying details of where to find the remote Alfresco for a given Remote System ID. The Remote System names should follow the system naming convention from RemoteCredentialsService TODO OAuth support

Since:

4.0.2

Method Detail

storeRemoteCredentials

BaseCredentialsInfo storeRemoteCredentials(String remoteSystemId,
                                           String username,
                                           String password)
                                    throws org.alfresco.repo.security.authentication.AuthenticationException,
                                           RemoteSystemUnavailableException,
                                           NoSuchSystemException

Validates and stores the remote credentials for the current user

Parameters:

remoteSystemId - The ID of the remote system, as registered with the service

Throws:

org.alfresco.repo.security.authentication.AuthenticationException - If the credentials are invalid

RemoteSystemUnavailableException - If the remote system is unavailable

NoSuchSystemException - If no system has been registered with the given ID

getRemoteCredentials

BaseCredentialsInfo getRemoteCredentials(String remoteSystemId)
                                  throws NoSuchSystemException

Retrieves the remote credentials (if any) for the current user

Parameters:

remoteSystemId - The ID of the remote system, as registered with the service

Returns:

The current user's remote credentials, or null if they don't have any

Throws:

NoSuchSystemException - If no system has been registered with the given ID

deleteRemoteCredentials

boolean deleteRemoteCredentials(String remoteSystemId)
                         throws NoSuchSystemException

Deletes the remote credentials (if any) for the current user

Parameters:

remoteSystemId - The ID of the remote system, as registered with the service

Returns:

Whether credentials were found to delete

Throws:

NoSuchSystemException - If no system has been registered with the given ID

getAlfrescoTicket

RemoteAlfrescoTicketInfo getAlfrescoTicket(String remoteSystemId)
                                    throws org.alfresco.repo.security.authentication.AuthenticationException,
                                           NoCredentialsFoundException,
                                           NoSuchSystemException,
                                           RemoteSystemUnavailableException

Returns the current Alfresco Ticket for the current user on the remote system, fetching if it isn't already cached. Note that because tickets are cached, it is possible that a ticket has become invalid (due to timeout or server restart). If the ticket is rejected by the remote server, you should call refetchAlfrescoTicket(String) to ensure you have the latest ticket, and re-try the request.

Parameters:

remoteSystemId - The ID of the remote system, as registered with the service

Returns:

The Alfresco Ticket for the current user on the remote system

Throws:

org.alfresco.repo.security.authentication.AuthenticationException - If the stored remote credentials are now invalid

NoCredentialsFoundException - If the user has no stored credentials for the remote system

NoSuchSystemException - If no system has been registered with the given ID

RemoteSystemUnavailableException - If it was not possible to talk to the remote system

refetchAlfrescoTicket

RemoteAlfrescoTicketInfo refetchAlfrescoTicket(String remoteSystemId)
                                        throws org.alfresco.repo.security.authentication.AuthenticationException,
                                               NoCredentialsFoundException,
                                               NoSuchSystemException,
                                               RemoteSystemUnavailableException

Forces a re-fetch of the Alfresco Ticket for the current user, if possible, and marks the credentials as failing if not. Normally getAlfrescoTicket(String) should be used initially, with this only used if the ticket received is rejected by the remote server.

Parameters:

remoteSystemId - The ID of the remote system, as registered with the service

Returns:

The Alfresco Ticket for the current user on the remote system

Throws:

org.alfresco.repo.security.authentication.AuthenticationException - If the stored remote credentials are now invalid

NoCredentialsFoundException - If the user has no stored credentials for the remote system

NoSuchSystemException - If no system has been registered with the given ID

RemoteSystemUnavailableException - If it was not possible to talk to the remote system

registerRemoteSystem

void registerRemoteSystem(String remoteSystemId,
                          String baseUrl,
                          Map<String,String> requestHeaders)

Registers the details of a new Remote System with the service.

Parameters:

remoteSystemId - The ID to be used to identify the system

baseUrl - The base URL of Alfresco Services on the remote system, eg http://localhost:8080/alfresco/service/

requestHeaders - Any HTTP headers that must be sent with the request when talking to the server
