Reproduce a complex curl request with httr2 or httr

General

I usually scrape web pages with rvest::read_html(); however, this time I want to read an html page using a residential proxy:

Proxy username: username

Proxy password: password

Proxy hostname: geo.iproyal.com (my residential proxy service)

Proxy port: port

Let's also assume that I'm trying to read the following web page: https://ipv4.icanhazip.com

The website for my residential proxy service provide the following curl request which works perfectly:

$ curl -v -x http://username:password@geo.iproyal.com:port -L https://ipv4.icanhazip.com

where $ refers to a bash shell.

My goal is to reproduce this curl request using {httr} or {httr2}. Here is my (failed) attempt:

username <- "username"
password <- "password"
port <- "port"
url <- "https://ipv4.icanhazip.com"

req <- httr2::request(base_url = url) |>
    httr2::req_proxy(
      url = "geo.iproyal.com",
      port = port,
      username = username,
      password = password,
      auth = "basic"
)

Thanks in advance for your help.

Fun timing, you might find your answer here or there.

Well it seems that the flags used in the curl request are not currently supported. Thank you for showing those. Also @maelle did tell me about curl_translate().
