Pagination

[Nicholas-Robinson]

I am a little confused with the pagination stuff - I assume that "number" is the page number and "totalPages" is the total number that there will be.

I am confused because number starts at 0 and ends at totalPages - 1, I also cannot request page 0 (even though the 500 error says that index cannot be less than zero).

I am trying to request the next page and I was using load page number + 1 .. But this was just loading the same page every time.

There are two endpoints for recipes with pagination.

1. http://www.computingfacts.com/openhouse/api/recipe/recipes/pageable

For the above endpoint, default for first page =0 and size =10, try this

curl -X GET --header 'Accept: application/hal+json' --header 'Authorization: Bearer eyJhbGciOiJIUzUxMiJ9.eyJzdWIiOiJibGFja25pdGVlIiwiaWF0IjoxNTAyNDkwNjc2LCJleHAiOjE1MzQwMjY2NzZ9.oyvcPaT1Thnqs5wuwZ3HXPMUgJYHr00koHObQIkz41R0TXQsrPvBJnwie6QJFcyH_Rzv7dIlEqRhcZ8kJVhCqQ' 'http://www.computingfacts.com/openhouse/api/recipe/recipes/pageable?page=0&size=10'

To get the second page try this

curl -X GET --header 'Accept: application/hal+json' --header 'Authorization: Bearer eyJhbGciOiJIUzUxMiJ9.eyJzdWIiOiJibGFja25pdGVlIiwiaWF0IjoxNTAyNDkwNjc2LCJleHAiOjE1MzQwMjY2NzZ9.oyvcPaT1Thnqs5wuwZ3HXPMUgJYHr00koHObQIkz41R0TXQsrPvBJnwie6QJFcyH_Rzv7dIlEqRhcZ8kJVhCqQ' 'http://www.computingfacts.com/openhouse/api/recipe/recipes/pageable?page=1&size=10'

Below is the result which shows the second page, in this case just one result.
