Scripted REST Connector
Important
Connectors continue to be released outside the IDM release. For the latest documentation, refer to the ICF documentation.
The Scripted REST connector is an implementation of the Scripted Groovy Connector Toolkit. This connector enables you to interact with any REST API, using Groovy scripts for the ICF operations.
Note
The Scripted REST connector is not a poolable connector.
Configuring the Scripted REST Connector
The Scripted REST Connector is bundled in the JAR openidm/connectors/scriptedrest-connector-1.5.20.11.jar
.
A sample connector configuration and scripts are provided in the /path/to/openidm/samples/scripted-rest-with-dj/
directory and described in Connect to DS With ScriptedREST. The scripts provided with this sample demonstrate how the connector can be used but most likely cannot be used as is in your deployment. They are a good starting point on which to base your customization. For information about writing your own scripts, see Writing Scripted Connectors With the Groovy Connector Toolkit.
Using the Scripted REST Connector With a Proxy Server
If the IDM server is hosted behind a firewall and requests to the resource are routed through a proxy, you must specify the proxy host and port in the connector configuration.
To specify the proxy server details, set the proxyAddress
property in the connector configuration. For example:
"configurationProperties": { ... "proxyAddress": "http://myproxy:8080", ... }
Run scripts through the connector
Groovy Toolkit connectors have two operations that allow you to run arbitrary script actions: runScriptOnConnector
and runScriptOnResource
. runScriptOnConnector
is an operation that sends the script action to the connector to be compiled and executed. runScriptOnResource
is an operation that sends the script to another script to be handled.
runScriptOnConnector
The runScriptOnConnector
script lets you run an arbitrary script action through the connector. This script takes the following variables as input:
configuration
A handler to the connector's configuration object.
options
A handler to the Operation Options.
operation
The operation type that corresponds to the action.
log
A handler to the connector's log.
To run an arbitrary script on a Groovy Toolkit connector, define the script in the systemActions
property of your provisioner file:
"systemActions" : [ { "scriptId" : "MyScript", "actions" : [ { "systemType" : ".*ScriptedConnector", "actionType" : "groovy", "actionFile" : "path/to/scriptname.groovy" } ] } ]
If you wish to define your script in the provisioner file itself rather than in a separate file, you can use the actionSource
property instead of the actionFile
one. A simple example follows:
"systemActions" : [ { "scriptId" : "MyScript", "actions" : [ { "systemType" : ".*ScriptedConnector", "actionType" : "groovy", "actionSource" : "2 * 2" } ] } ]
Note
It is optional to prepend the last script statement in actionSource
with return
.
Running MyScript
will return:
{ "actions" : [ { "result": 4 } ] }
If your script accepts parameters, you can supply them in the request body or the query string. For example:
curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Content-Type: application/json" \
--header "Accept-API-Version: resource=1.0" \
--request POST \
--data-raw '{"param1":"value1"}' \
"http://localhost:8080/openidm/system/groovy?_action=script&scriptId=MyScript¶m2=value2"
You can also call it through the script engine. The system can accept arbitrary parameters:
openidm.action("/system/groovy", "script", {"contentParameter": "value"}, {"scriptId": "MyScript", "additionalParameter1": "value1", "additionalParameter2": "value2"})
runScriptOnResource
To run an arbitrary script using runScriptOnResource
, you must add some configuration details to your provisioner file. These details include a scriptOnResourceScriptFileName
that references a script file located in a path contained in the scriptRoots
array.
Define these properties in your provisioner file:
"configurationProperties": { "scriptRoots": [ "path/to/scripts" ], "scriptOnResourceScriptFileName": "ScriptOnResourceScript.groovy" }, "systemActions" : [ { "scriptId" : "script-1", "actions" : [ { "systemType" : ".*ScriptedConnector", "actionType" : "groovy", "actionFile" : "path/to/scriptname.groovy" } ] } ]
When you have defined the script, call it over REST on the system endpoint:
curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Content-Type: application/json" \
--header "Accept-API-Version: resource=1.0" \
--request POST \
"http://localhost:8080/openidm/system/groovy?_action=script&scriptId=scriptOnResourceScript&scriptExecuteMode=resource"
Implemented Interfaces
The following table lists the ICF interfaces that are implemented for the scripted REST connector:
OpenICF Interfaces Implemented by the Scripted REST Connector
The Scripted REST Connector implements the following OpenICF interfaces.
- Authenticate
Provides simple authentication with two parameters, presumed to be a user name and password.
- Create
Creates an object and its
uid
.- Delete
Deletes an object, referenced by its
uid
.- Resolve Username
Resolves an object by its username and returns the
uid
of the object.- Schema
Describes the object types, operations, and options that the connector supports.
- Script on Connector
Enables an application to run a script in the context of the connector. Any script that runs on the connector has the following characteristics:
The script runs in the same execution environment as the connector and has access to all the classes to which the connector has access.
The script has access to a
connector
variable that is equivalent to an initialized instance of the connector. At a minimum, the script can access the connector configuration.The script has access to any script-arguments passed in by the application.
- Script on Resource
Runs a script on the target resource that is managed by this connector.
- Search
Searches the target resource for all objects that match the specified object class and filter.
- Sync
Polls the target resource for synchronization events, that is, native changes to objects on the target resource.
- Test
Tests the connector configuration. Testing a configuration checks all elements of the environment that are referred to by the configuration are available. For example, the connector might make a physical connection to a host that is specified in the configuration to verify that it exists and that the credentials that are specified in the configuration are valid.
This operation might need to connect to a resource, and, as such, might take some time. Do not invoke this operation too often, such as before every provisioning operation. The test operation is not intended to check that the connector is alive (that is, that its physical connection to the resource has not timed out).
You can invoke the test operation before a connector configuration has been validated.
- Update
Updates (modifies or replaces) objects on a target resource.
