safe_get_content: Safely download and parse web content
Description
This helper function retrieves content from a given URL using httr.
It ensures that common issues (e.g. no internet, timeouts, HTTP errors,
or parsing errors) are handled gracefully with clear, informative error messages.
Usage
safe_get_content(url, ..., timeout_sec = 10)
Value
A character string containing the parsed content of the response
(UTF-8 encoded). On failure, an error is raised with a clear message.
Arguments
url
Character string. The URL of the resource to download.
Numeric. Timeout in seconds for the request (default = 10).
Details
This function is intended for use inside package functions.
For examples, vignettes, or tests, wrap calls in a connectivity check
(e.g. using http_error(HEAD(url))) to avoid CRAN failures
when the resource is temporarily unavailable.
