# httr

## Status

[![Lifecycle: superseded](https://img.shields.io/badge/lifecycle-superseded-blue.svg)](https://lifecycle.r-lib.org/articles/stages.html#superseded)

httr is superseded: only changes necessary to keep it on CRAN will be made. We recommend using [httr2](https://httr2.r-lib.org) instead.

---

[![CRAN status](https://www.r-pkg.org/badges/version/httr)](https://cran.r-project.org/package=httr)

[![R-CMD-check](https://github.com/r-lib/httr/actions/workflows/R-CMD-check.yaml/badge.svg)](https://github.com/r-lib/httr/actions/workflows/R-CMD-check.yaml)

[![Codecov test coverage](https://codecov.io/gh/r-lib/httr/branch/main/graph/badge.svg)](https://app.codecov.io/gh/r-lib/httr?branch=main)

The aim of httr is to provide a wrapper for the [curl](https://cran.r-project.org/package=curl) package, customised to the demands of modern web APIs.

Key features:

* Functions for the most important http verbs: `GET()`, `HEAD()`, `PATCH()`, 

  `PUT()`, `DELETE()` and `POST()`.

* Automatic connection sharing across requests to the same website (by

  default, curl handles are managed automatically), cookies are maintained

  across requests, and a up-to-date root-level SSL certificate store is used.

* Requests return a standard reponse object that captures the http status line,

  headers and body, along with other useful information.

  * Response content is available with `content()` as a raw vector (`as =

    "raw"`), a character vector (`as = "text"`), or parsed into an R object

    (`as = "parsed"`), currently for html, xml, json, png and jpeg.

  * You can convert http errors into R errors with `stop_for_status()`.

* Config functions make it easier to modify the request in common ways:

  `set_cookies()`, `add_headers()`, `authenticate()`, `use_proxy()`, 

  `verbose()`, `timeout()`, `content_type()`, `accept()`, `progress()`.

* Support for OAuth 1.0 and 2.0 with `oauth1.0_token()` and `oauth2.0_token()`.

  The demo directory has eight OAuth demos: four for 1.0 (twitter, vimeo,

  withings and yahoo) and four for 2.0 (facebook, github, google, linkedin). 

  OAuth credentials are automatically cached within a project. 

httr wouldn't be possible without the hard work of the authors of [curl](https://cran.r-project.org/package=curl) and [libcurl](https://curl.se/). Thanks! httr is inspired by http libraries in other languages, such as [Resty](http://beders.github.io/Resty/Resty/Examples.html), [Requests](https://requests.readthedocs.io/en/latest/) and [httparty](https://github.com/jnunemaker/httparty/tree/master).
