Scripting function reference

If you need to request specific resource versions, see REST API versioning.

Functions (access to managed objects, system objects, and configuration objects) within IDM are accessible to scripts via the openidm object, which is included in the top-level scope provided to each script.

Most of the following function examples are in JavaScript. To use the functions in Groovy scripts, make adjustments as necessary. For example, you need to pass parameters using square brackets (not curly braces):

openidm.query("managed/user", ["_queryFilter" : "/userName sw \"user.1\""], ["userName", "_id"])

The script engine supports the following functions:

openidm.create(resourceName, newResourceId, content, params, fields)

This function creates a new resource object.

Parameters

resourceName: string

The container in which the object will be created, for example, managed/user.
newResourceId: string

The identifier of the object to be created, if the client is supplying the ID. If the server should generate the ID, pass null here.
content: JSON object

The content of the object to be created.
params: JSON object (optional)

Additional parameters that are passed to the create request.
fields: JSON array (optional)

An array of the fields that should be returned in the result. The list of fields can include wild cards, such as * or *_ref. If no fields are specified, the entire new object is returned.

Returns

The created resource object.

Throws

An exception is thrown if the object could not be created.

Example

openidm.create("managed/user", ID, JSON object);

openidm.patch(resourceName, rev, value, params, fields)

This function performs a partial modification of a managed or system object. Unlike the update function, only the modified attributes are provided, not the entire object.

Parameters

resourceName

string

The full path to the object being updated, including the ID.

rev

string

The revision of the object to be updated. Use null if the object is not subject to revision control, or if you want to skip the revision check and update the object, regardless of the revision.

value

An array of one or more JSON objects

The value of the modifications to be applied to the object. The patch set includes the operation type, the field to be changed, and the new values. A PATCH request can add, remove, replace, or increment an attribute value.

A remove operation removes a property if the value of that property equals the specified value, or if no value is specified in the request. The following example value removes the marital_status property from the object, if the value of that property is single:

[
    {
        "operation": "remove",
        "field": "marital_status",
        "value": "single"
    }
]

For fields whose value is an array, it’s not necessary to know the position of the value in the array, as long as you specify the full object. If the full object is found in the array, that value is removed. The following example removes user adonnelly from bjensen’s reports:

{
    "operation": "remove",
    "field": "/manager",
    "value": {
      "_ref": "managed/user/adonnelly",
      "_refResourceCollection": "managed/user",
      "_refResourceId": "adonnelly",
      "_refProperties": {
        "_id": "ed6620e4-98ba-410c-abc0-e06dc1be7aa7",
        "_rev": "000000008815942b"
      }
    }
}

If an invalid value is specified (that is a value that does not exist for that property in the current object) the patch request is silently ignored.

A replace operation replaces an existing value, or adds a value if no value exists.

params

JSON object (optional)

Additional parameters that are passed to the patch request.

fields

JSON array (optional)

An array of the fields that should be returned in the result. The list of fields can include wild cards, such as * or *_ref. If no fields are specified, the entire new object is returned.

Returns

The modified resource object.

Throws

An exception is thrown if the object could not be updated.

Examples

Patching an object to add a value to an array:

openidm.patch("managed/role/" + role._id, null, [{"operation":"add", "field":"/members/-", "value": {"_ref":"managed/user/" + user._id}}]);

Patching an object to remove an existing property:

openidm.patch("managed/user/" + user._id, null, [{"operation":"remove", "field":"marital_status", "value":"single"}]);

Patching an object to replace a field value:

openidm.patch("managed/user/" + user._id, null, [{"operation":"replace", "field":"/password", "value":"Passw0rd"}]);

Patching an object to increment an integer value:

openidm.patch("managed/user/" + user._id, null, [{"operation":"increment","field":"/age","value":1}]);

openidm.read(resourceName, params, fields)

This function reads and returns a resource object.

Parameters

resourceName: string

The full path to the object to be read, including the ID.
params: JSON object (optional)

The parameters that are passed to the read request. Generally, no additional parameters are passed to a read request, but this might differ, depending on the request. If you need to specify a list of fields as a third parameter, and you have no additional params to pass, you must pass null here. Otherwise, you simply omit both parameters.
fields: JSON array (optional)

An array of the fields that should be returned in the result. The list of fields can include wild cards, such as * or *_ref. If no fields are specified, the entire object is returned.

Returns

The resource object, or null if not found.

Example

openidm.read("managed/user/"+userId, null, ["*", "manager"]);

openidm.update(resourceName, rev, value, params, fields)

This function updates an entire resource object.

Parameters

id: string

The complete path to the object to be updated, including its ID.
rev: string

The revision of the object to be updated. Use null if the object is not subject to revision control, or if you want to skip the revision check and update the object, regardless of the revision.
value: object

The complete replacement object.
params: JSON object (optional)

The parameters that are passed to the update request.
fields: JSON array (optional)

An array of the fields that should be returned in the result. The list of fields can include wild cards, such as * or *_ref. If no fields are specified, the entire object is returned.

Returns

The modified resource object.

Throws

An exception is thrown if the object could not be updated.

Example

In this example, the managed user entry is read (with an openidm.read, the user entry that has been read is updated with a new description, and the entire updated object is replaced with the new value.

var user_read = openidm.read('managed/user/' + source._id);
user_read['description'] = 'The entry has been updated';
openidm.update('managed/user/' + source._id, null, user_read);

openidm.delete(resourceName, rev, params, fields)

This function deletes a resource object.

Parameters

resourceName: string

The complete path to the to be deleted, including its ID.
rev: string

The revision of the object to be deleted. Use null if the object is not subject to revision control, or if you want to skip the revision check and delete the object, regardless of the revision.
params: JSON object (optional)

The parameters that are passed to the delete request.
fields: JSON array (optional)

An array of the fields that should be returned in the result. The list of fields can include wild cards, such as * or *_ref. If no fields are specified, the entire object is returned.

Returns

Returns the deleted object if successful.

Throws

An exception is thrown if the object could not be deleted.

Example

openidm.delete('managed/user/'+ user._id, user._rev);

openidm.query(resourceName, params, fields)

This function performs a query on the specified resource object. For more information, see Construct Queries.

Parameters

resourceName

string

The resource object on which the query should be performed, for example, "managed/user", or "system/ldap/account".

params

JSON object

The parameters that are passed to the query (_queryFilter, or _queryId). Additional parameters passed to the query will differ, depending on the query.

Certain common parameters can be passed to the query to restrict the query results. The following sample query passes paging parameters and sort keys to the query.

reconAudit = openidm.query("audit/recon", {
    "_queryFilter": queryFilter,
    "_pageSize": limit,
    "_pagedResultsOffset": offset,
    "_pagedResultsCookie": string,
    "_sortKeys": "-timestamp"
});

For more information about _queryFilter syntax, see Common Filter Expressions. For more information about paging, see Page Query Results.

fields

list

A list of the fields that should be returned in the result. The list of fields can include wild cards, such as * or *_ref. The following example returns only the userName and _id fields:

openidm.query("managed/user", { "_queryFilter": "/userName sw \"user.1\""}, ["userName", "_id"]);

This parameter is particularly useful in enabling you to return the response from a query without including intermediary code to massage it into the right format.

Fields are specified as JSON pointers.

Returns

The result of the query. A query result includes the following parameters:

query-time-ms

(For JDBC repositories only) the time, in milliseconds, that IDM took to process the query.

result

The list of entries retrieved by the query. The result includes the properties that were requested in the query.

The following example shows the result of a custom query that requests the ID, user name, and email address of all managed users in the repository.

{
  "result": [
    {
      "_id": "9dce06d4-2fc1-4830-a92b-bd35c2f6bcbb",
      "_rev": "00000000a059dc9f",
      "userName": "bjensen",
      "mail": "bjensen@example.com"
    },
    {
      "_id": "42f8a60e-2019-4110-a10d-7231c3578e2b",
      "_rev": "00000000d84ade1c",
      "userName": "scarter",
      "mail": "scarter@example.com"
    }
  ],
  "resultCount": 2,
  "pagedResultsCookie": null,
  "totalPagedResultsPolicy": "NONE",
  "totalPagedResults": -1,
  "remainingPagedResults": -1
}

Throws

An exception is thrown if the given query could not be processed.

Examples

The following sample query uses a _queryFilter to query the managed user repository:

openidm.query("managed/user", {'_queryFilter': userIdPropertyName + ' eq "' + security.authenticationId  + '"'});

The following sample query references the for-userName query, defined in the repository configuration, to query the managed user repository:

openidm.query("managed/user", {"_queryId": "for-userName", "uid": request.additionalParameters.uid });

openidm.action(resource, actionName, content, params, fields)

This function performs an action on the specified resource object. The resource and actionName are required. All other parameters are optional.

Parameters

resource: string

The resource that the function acts upon, for example, managed/user.
actionName: string

The action to execute. Actions are used to represent functionality that is not covered by the standard methods for a resource (create, read, update, delete, patch, or query). In general, you should not use the openidm.action function for create, read, update, patch, delete or query operations. Instead, use the corresponding function specific to the operation (for example, openidm.create).

Using the operation-specific functions lets you benefit from the well-defined REST API, which follows the same pattern as all other standard resources in the system. Using the REST API enhances usability for your own API, and enforces the established patterns.

IDM-defined resources support a fixed set of actions. For user-defined resources (scriptable endpoints) you can implement whatever actions you require.

Supported Actions Per Resource

The following list outlines the supported actions for each resource or endpoint. The actions listed here are also supported over the REST interface.

Actions supported on the authentication endpoint (authentication/*)

reauthenticate

Actions supported on the configuration resource (config/)

No action parameter applies.

Actions supported on custom endpoints

Custom endpoints enable you to run arbitrary scripts through the REST URI, and are routed at endpoint/name, where name generally describes the purpose of the endpoint. For more information on custom endpoints, see Create custom endpoints to launch scripts. You can implement whatever actions you require on a custom endpoint. IDM uses custom endpoints in its workflow implementation. Those endpoints, and their actions are as follows:

endpoint/getprocessforuser - create, complete
endpoint/gettasksview - create, complete

Actions supported on the external endpoint

external/email - send, for example:

{
    emailParams = {
        "from" : 'admin@example.com',
        "to" : user.mail,
        "subject" : 'Password expiry notification',
        "type" : 'text/plain',
        "body" : 'Your password will expire soon. Please change it!'
    }
    openidm.action("external/email", "send",  emailParams);
}

external/email - sendTemplate, for example:

{
    emailParams = {
        "templateName" : "welcome",
        "to" : user.mail,
        "cc" : "ccUser1@example.com,ccUser2@example.com",
        "bcc" : "bigBoss@example.com"
    }
    openidm.action("external/email", "sendTemplate",  emailParams);
}

external/rest - call, for example:

openidm.action("external/rest", "call", params);

Actions supported on the info endpoint (info/*)

No action parameter applies.

Actions supported on managed resources (managed/*)

patch, triggerSyncCheck

Actions supported on the policy resource (policy)

validateObject, validateProperty

For example:

openidm.action("policy/" + fullResourcePath, "validateObject", request.content, { "external" : "true" });

Actions supported on the reconciliation resource (recon)

recon, reconById, cancel

For example:

openidm.action("recon/_id", "cancel", content, params);

A cancel action requires the entire reconciliation resource path (_id).

Actions supported on the repository (repo)

command

For example:

var r, command = {
    "commandId": "purge-by-recon-number-of",
    "numberOf": numOfRecons,
    "includeMapping": includeMapping,
    "excludeMapping": excludeMapping
};
r = openidm.action("repo/audit/recon", "command", {}, command);

Actions supported on the script resource (script)

eval

For example:

openidm.action("script", "eval", getConfig(scriptConfig), {});

Actions supported on the synchronization resource (sync)

getLinkedResources, notifyCreate, notifyDelete, notifyUpdate, performAction

For example:

openidm.action('sync', 'performAction', content, params);

Actions supported on system resources (system/*)

availableConnectors, createCoreConfig, createFullConfig, test, testConfig, liveSync, authenticate, script

For example:

openidm.action("system/ldap/account", "authenticate", {"username" : "bjensen", "password" : "Passw0rd"});

Actions supported on the task scanner resource (taskscanner)

execute, cancel

Actions supported on the workflow resource (workflow/*)

On workflow/processdefinition create, complete

On workflow/processinstance create, complete

For example:

var params = {
    "_key":"contractorOnboarding"
};
openidm.action('workflow/processinstance', 'create', params);

On workflow/taskinstance claim, create, complete

For example:

var params = {
    "userId":"manager1"
};
openidm.action('workflow/taskinstance/15', 'claim', params);

content

object

Content given to the action for processing.

params

object (optional)

Additional parameters passed to the script. The params object must be a set of simple key:value pairs, and cannot include complex values. The parameters must map directly to URL variables, which take the form name1=val1&name2=val2&….

fields

JSON array (optional)

An array of the fields that should be returned in the result. The list of fields can include wild cards, such as * or *_ref. If no fields are specified, the entire object is returned.

Returns: The result of the action may be null.
Throws: If the action cannot be executed, an exception is thrown.

A hashed value to compare to the string.

Returns

Boolean, true if the hash of the string matches the hashed value, and false otherwise.

Throws

An exception is thrown if the string could not be hashed.

These functions can also have a vanity binding to make them more descriptive, such as consent.action() instead of openidm.action("consent" ...), by setting resourceBindings when you declare the script. In this case, the syntax for these functions would omit the resource name from the function parameters.

See Call a script from the IDM configuration for more information about resourceBindings.

Log functions

IDM also provides a logger object to access the Simple Logging Facade for Java (SLF4J) facilities. The following code shows an example of the logger object.

logger.info("Parameters passed in: {} {} {}", param1, param2, param3);

To set the log level for JavaScript scripts, add the following property to your project’s conf/logging.properties file:

org.forgerock.openidm.script.javascript.JavaScript.level

The level can be one of SEVERE (highest value), WARNING, INFO, CONFIG, FINE, FINER, or FINEST (lowest value). For example:

org.forgerock.openidm.script.javascript.JavaScript.level=WARNING

In addition, JavaScript has a useful logging function named console.log(). This function provides an easy way to dump data to the IDM standard output (usually the same output as the OSGi console). The function works well with the JavaScript built-in function JSON.stringify and provides fine-grained details about any given object. For example, the following line will print a formatted JSON structure that represents the HTTP request details to STDOUT.

console.log(JSON.stringify(context.http, null, 4));

These logging functions apply only to JavaScript scripts. To use the logging functions in Groovy scripts, the following lines must be added to the Groovy scripts:

import org.slf4j.*;
logger = LoggerFactory.getLogger('logger');

The script engine supports the following log functions:

logger.debug(string message, object… params)
