Magnolia's REST Web service allows you to manipulate content through a Web API. You can create, read, update and delete nodes in the JCR. The nodes can be pages, components, contacts or anything else that is stored in a named workspace. You can also execute commands to activate, export and import content.
The REST service is similar to the Data module in Magnolia 4.5 which pulled data from other sources into Magnolia. However, REST works with the push principle where your application communicates with a Magnolia REST endpoint and exchanges a representation of a resource such as an XML of a page. REST is useful for connection tasks. Use REST to push product data from a third party system into Magnolia and let editors enrich it in a Magnolia app, for example.
Magnolia's REST Web services consist of three modules.
This module installs the endpoints of the REST API: node, property and command.
The REST Integration module installs the integration part of REST. The module:
/config/<module-name>/rest-endpointsfor any new endpoints you want to register. The monitoring mechanism is the same as used for observing registered dialogs, templates and apps.
- Installs a special servlet
RestDispatcherServletwhich dispatches requests to the individual endpoints registered in configuration.
- Lets you define additional providers or marshallers (called
MessageBodyWorkersin RESTeasy) you might need. The providers are responsible for translating the return object into JSON/XML and vice-versa.
- Installs the default
restrole that initially prevents access to unauthorized requests.
The REST Tools module extends the
RestDispatcherServlet with a custom, API-aware servlet that can read API annotations from all available REST endpoints. The servlet enables the endpoints in the Swagger API explorer. If you write your own endpoint you need to add annotations in the code yourself. Not installed by default.
Maven is the easiest way to install the modules. Add the following dependencies to your bundle:
<dependency> <groupId>info.magnolia.rest</groupId> <artifactId>magnolia-rest-services</artifactId> <version>1.2.1</version> </dependency>
<dependency> <groupId>info.magnolia.rest</groupId> <artifactId>magnolia-rest-integration</artifactId> <version>1.2.1</version> </dependency>
<dependency> <groupId>info.magnolia.rest</groupId> <artifactId>magnolia-rest-tools</artifactId> <version>1.2.1</version> </dependency>
Pre-built jars are also available for download. See Installing a module for help.
Preconfigured Magnolia bundles contain the modules magnolia-rest-services and magnolia-rest-integration but not magnolia-rest-tools. When adding magnolia-rest-tools directly to your bundle, please unpack the zip file and add all its files to WEB-INF/libs of your webapps.
Setting the API base path
The Swagger API explorer tool searches for the API at a path set in
/modules/rest-tools/config/apiBasepath. The default value is
. The value for this property must match the following pattern:
When using one of Magnolia's preconfigured bundles running on localhost, set the property to
Set the path to where REST services reside on your system. If you run the standard Magnolia bundle and work on the author instance, set the path to
After setting the base path, restart Magnolia.
Swagger is in Dev > REST Tools.
Permissions to issue REST requests are controlled using Magnolia's standard role-based security mechanism.
The REST module installs a
rest role which has the permission to issue requests to the
properties endpoints by default.
|Get & Post|
|Get & Post|
|Get & Post|
|Get & Post|
superuser account has the
rest role by default so you can use superuser to test your requests. However, for production use you should create a dedicated account for REST. The
anonymous account is specifically denied access to the REST endpoints.
Enabling commands (optional)
Commands are custom actions executed at pre-defined trigger points. Magnolia uses commands to activate content, send email, flush the cache, take backups, import and export data, and to do many other tasks. Commands can perform duties within the system or connect to external resources.
You can make sweeping changes with commands, such as bypassing approval and deleting the whole site. Commands are therefore subject to a special security restrictions.
To enable the use of commands through REST:
- Open the security app and grant the
restrole a permission to the issue requests to the
commandsendpoint. Permission to the endpoint is denied by default. Add a new rule.
- Whitelist any commands you want to expose to REST. The white list is managed in
Enabled commands node.
Arbitrary name for the command. Use any name you like.
Role name. Grants the role permission to execute the command . Add the default
Catalog where the command resides.
Command definition name.
