The Token Server uses the Thymeleaf template engine to serve pages to the end user via a browser. The templates can be customized to align their look and feel with your mobile application or company standards.
The Token Server uses template sets which contain one or more custom templates. The default template is used when a specific template is not available in the template set. One custom template set can be marked as the default template set for all applications and web clients.
Customized templates can be uploaded and managed via the Token Server admin console. Upload a zip file with the templates to add or modify a custom template set. The main templates must be in the root of the archive. As a reference for the custom template set archive please refer to the default template set.
In the templates the Thymeleaf Layout Dialect and Thymeleaf With Dialect are supported. The template file names are hardcoded and should be equal in the custom template set. The internals of the template like message keys and fragments can be different. For more details about the different templates supported by the Token Server see the templates section in the appendix.
To distribute a templates set from for example a test environment to a production environment it can be exported and imported on the other system. Different versions of a template set can be uploaded by giving them a different name to switch between an old and a new version.
Configuring an application specific template set
For each mobile application and web client a template set can be configured to render screens in the look and feel of this application or web client. When no template set is configured for an application or web client, the default template set is used to render these screens.
Onegini Token Server resolves templates in the following order:
- Within the template set that is configured for the application or web client of the current request.
- When the template is not present in this set, within the template set that is marked as the default template set.
- When no template set is marked as default or when the template is not found, within the templates that are bundled with Onegini Token Server.
- Embed the static resources in the html of the templates. The downside is that the client cannot cache the static resource.
- Serve the static resources via the organisations content management system.
- Serve the static resources via the Onegini Content Server, docker based micro service which can optionally be deployed next to the Token Server.
