R Documentation

What kind of page is this?

Description

Inspects already-fetched HTML for the three things that are not a classifiable site: an anti-bot interstitial, a domain-parking placeholder, and a server's "nothing here" page. No network access.

Usage

page_signals(html, text = NULL, domain = "", status = NULL)

Arguments

`html`	Raw response body.
`text`	Extracted page text. If 'NULL', derived from 'html'.
`domain`	The domain requested, used to spot a page whose only content is its own name.
`status`	HTTP status code, if known.

Details

'parked' and 'unavailable' are **answers, not failures** – they are facts about the domain, plainly stated in the page, that a caller can act on. They are also free: no classification service needs to be consulted.

Value

A one-row tibble: 'page_state' (one of '"content"', '"blocked"', '"parked"', '"unavailable"', '"thin"'), 'blocked', 'block_vendor', 'block_reason', 'parked', 'unavailable', 'thin', 'n_tokens'.

Examples

# A Cloudflare challenge, not a website
page_signals("<html><title>Just a moment...</title><body>cf_chl_opt</body></html>")

# A parking page
page_signals("<html><body>This domain is for sale. Inquire now.</body></html>")

# A real page that merely embeds reCAPTCHA is not blocked
page_signals(paste0("<html><title>Reddit</title><body>",
                    paste(rep("real discussion content", 200), collapse = " "),
                    "<script src='recaptcha/api.js'></script></body></html>"))
