Invoking the Service using the in-built Swagger UI

Follow the steps below to invoke the added service using the in-built Swagger UI.

Click the following Go to Store button in the top right hand corner of the G-Reg Publisher Home Page, to access the G-Rg Store:
Log in to the G-Reg Store using the following URL and admin/admin credentials: https://<G-REG_HOST>:<G-REG_PORT>/store

Click the Swagger which you added as shown below.
Click the following Swagger UI button, to invoke the Service using the in-built Swagger UI:
Click the pet link in the Swagger UI, and then click on the GET /pet/{petId} box to expand it as shown below.
Enter a value for petId, and click the Try it out! button as shown below, to make an invocation.
Click the icon next to the address bar of your browser, and then click Load unsafe scripts (if you are using Google Chrome) as shown below.

This step is required to enable scripts from unauthenticated sources since by default they are blocked in Web browsers as a standard. Hence, if your page supports http, it will not allow to load content which uses the https protocol and vice versa. You will view different message pop-ups depending on the Web browser you use. For more information on this, see Chrome and Firefox: Blocked Mixed (HTTPS and HTTP) Content.
Repeat steps 6 and 7 above. You view the response of the Service invocation as shown below.
