parse_headers: Parse response headers

In jeroenooms/curl: A Modern and Flexible Web Client for R

Parse response headers

Description

Parse response header data as returned by curl_fetch, either as a set of strings or into a named list.

Usage

parse_headers(txt, multiple = FALSE)

parse_headers_list(txt)

Arguments

txt	raw or character vector with the header data
multiple	parse multiple sets of headers separated by a blank line. See details.

Details

The parse_headers_list function parses the headers into a normalized (lowercase field names, trimmed whitespace) named list.

If a request has followed redirects, the data can contain multiple sets of headers. When multiple = TRUE, the function returns a list with the response headers for each request. By default it only returns the headers of the final request.

Examples

req <- curl_fetch_memory("https://hb.cran.dev/redirect/3")
parse_headers(req$headers)
parse_headers(req$headers, multiple = TRUE)

# Parse into named list
parse_headers_list(req$headers)
