2 Accessing the Web Service Interfaces
Accessing WSDL
The Web Service Description Language or WSDL (See Reference [1]) definition of IO operations
can be accessed from any installed IO system using a web browser. For example, if the software
is installed on a server with an IP address of <cms-ip-address>, enter the following into the
web browser to access the WSDL:
https://<cms-ip-address>:51443/hpio/controller/soap/v5?wsdl
The browser will show the formal XML definition of the Web Service Interface. The IO API is already
available in the embedded Operations Orchestration when IO is installed.
Security
The IO Web Service is only accessible over HTTPS. The service uses WS-Security UsernameToken
authentication in text form. A username and password of a registered IO user is required to access
the Web Service Interface. A WS-Security timestamp header is also required.
Authorization
If the presented username/password belongs to a Windows user in the Service Provider
Administrator role, the web services are able to view and act on all services. For
username/passwords that belong to a Windows user in the Organization Administrator role, the
web services can operate only on the services owned by that organization. For username/passwords
that belong to Windows users in the Architect or User roles, the web services are only able to view
or act on the services owned by that particular user.
The Activate Service operation (and others) specifies a list of server pools from which the servers
will be allocated. The set of available pools is based on the assignments of the requesting user
(not the service owner). For Administrator users, all pools except Maintenance and Unassigned
are available.
Impersonation
An “Impersonation” feature allows an authenticated Administrator role user to perform an operation
in the context of a specified requesting user. This behavior can be used in the implementation of
enterprise service catalogs to initiate operations on behalf of enterprise users. Impersonation is
achieved by including an HP-IO-Impersonate cookie in the HTTP message header. For example, if
the request includes the HTTP header “Cookie: HP-IO-Impersonate=Steve”, the operation will be
performed as though it were requested by Steve. A message is written to the audit log to record
the impersonation event.
Command Line Interface
An IO installation includes an “ioexec” command line interface (CLI) to access the IO Web Service.
The CLI may be useful for scripting web service invocations and for testing purposes when
developing a web service client. The CLI operations and data model mirror the Web Service
Interface. The CLI may be copied from an IO installation to a different system to operate on the
CMS remotely. The “ioexec” command help provides specific usage details.
