Examples

Example for authentication request

...

  • The JobScheduler REST Web Service (and the JOC Cockpit) are operated on the localhost with port 4446.
  • The URL in use is http://localhost:4446/joc/api/security/login
  • The Authorization header is used for HTTP Authentication, i.e. the constant value Basic and the base64 encoded user name and password separated by a colon.
  • Consider use of the Content-Type header application/json.
  • No body is required for this request.

 


The REST Web Service response is provided in JSON format and could look like this:
