Overview

About

Maintained by Hadley WickhamCRAN page ↗GitHub ↗Website ↗Issues ↗Declared funder: Posit Software, PBC

Tools for creating and modifying HTTP requests, then performing them and processing the results. 'httr2' is a modern re-imagining of 'httr' that uses a pipe-based interface and solves more of the problems that API wrapping packages face.

Changes in 1.3.0

Fixed OAuth token cache pruning so that it actually matches the encrypted .rds.enc files written to disk; previously the pruning pattern only matched an unencrypted .rds file that was never created, so cached tokens were never automatically deleted regardless of age.
httr2 now requires rlang >= 1.3.0, which changes the hash used to name files cached by req_cache() and on-disk OAuth token caches (e.g. from req_oauth_auth_code(cache_disk = TRUE)). Existing cached files won't match the new hash, so they'll be silently ignored (triggering a normal cache miss/re-authentication) and cleaned up over time by the usual pruning rules; you can also delete them manually.
oauth_cache_path() now defaults to a standard R cache directory (via tools::R_user_dir()). Because this release also changes the hash used for cache filenames, existing OAuth tokens will generally not be reused and you may need to authenticate once after upgrading. New tokens are written to the new location, and obsolete tokens in both the old and new locations are removed by the usual pruning rules. httr2 no longer requires the rappdirs package (#800).
New oauth_cache_prune() lets you manually delete cached OAuth tokens older than a given number of days, exposing the pruning that httr2 already performs automatically on load.
req_oauth_*() gains an expiry_margin argument to control how early cached OAuth tokens are treated as expired; the default margin increases from 5 to 30 seconds (@zacdav-db, #860).

From NEWS.md in the release

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("httr2", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("r-lib/httr2")

Development version from r-lib/httr2. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-httr2

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-httr2

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-httr2

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
