While a web script that returns HTML (such as the Hello World sample web
script) is fine for rendering a user interface, it is not so good for a data web script that
needs to returns a format that is machine-readable, such as JSON. (JSON, short for JavaScript
Object Notation, is a lightweight data interchange format, often used for transmitting
structured data over a network connection.)
A web script may offer multiple response formats where each format is supported by its own response template. Clients that invoke the web script either rely on the default response format or can explicitly ask for a specific response format.
Add another response format to the Hello User web script that returns the greeting in JSON format.
-
Log in to SkyVault Explorer.
- Type http://localhost:8080/SkyVault in the web browser.
- If prompted, log in with the user name admin and password admin.
- Navigate to Company Home > Data Dictionary > Web Scripts Extensions.
-
Create a new web script response template to render the Hello User greeting in
JSON.
- In the Create menu, click Create Content.
- Enter hellouser.get.json.ftl as the template name in the Name field.
- In the Content Type list, select Plain Text.
- Click Next.
-
Type the following in the Enter Content box.
{greeting: "hello", user: "${person.properties.userName}"} - Click Next.
- Click Finish.
- Click OK.
-
Re-register the Hello User web script with SkyVault.
- Type http://localhost:8080/alfresco/service/index in the web browser.
- If prompted, log in with the user name admin and password admin.
- Click Refresh Web Scripts.
A message indicates there is no additional web script (just a response format has been added).
-
Finally, type the following on the command line to test the web script.
curl -uadmin:admin "http://localhost:8080/alfresco/service/hellouser.json"
The message {greeting: "hello", user: "admin"} displays indicating your web script is working.
