paginate: Get responses from Canvas API pages

In ICTO-FMG/uvacanvas: Utility Functions for ICTO-FMG for CANVAS API

Description

The Canvas headers include a link object (usually), in form: Link: <https://canvas.url/api/v1/[...]?page=1&per_page=10>; rel="current", <https://canvas.url/api/v1/[...]?page=2&per_page=10>; rel="next", <https://canvas.url/api/v1/[...]?page=1&per_page=10>; rel="first", <https://canvas.url/api/v1/[...]?page=15&per_page=10>; rel="last"

In this case, we need to download every page from 1 to 15 to capture all data. This function parses the response object intelligently, using only HEAD requests, to figure out these page requirements.

Usage

paginate(x)

Arguments

x	a httr response object

Value

unparsed responses

Examples

## Not run: resp <- canvas_query(url, args, "HEAD")
get_pages(resp)
## End(Not run)
