The aim of httr is to provide a wrapper for the 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.

HTTParty is a Ruby library that makes it easy to work with HTTP requests and responses. It is built on top of the Ruby standard library's Net::HTTP and provides a simple, easy-to-use interface for making requests and handling responses.

One of the main features of HTTParty is its ability to automatically parse response bodies as JSON, XML, or other formats. This allows developers to easily access the data returned by an API without having to manually parse the response.

Example Use


library(httr)

# GET requests:
resp <- GET("http://httpbin.org/get")
status_code(resp)  # status code
headers(resp)  # headers
str(content(resp))  # body

# POST requests: 
# Form encoded
resp <- POST(url, body = body, encode = "form")
# Multipart encoded
resp <- POST(url, body = body, encode = "multipart")
# JSON encoded
resp <- POST(url, body = body, encode = "json")

# setting cookies:
resp <- GET("http://httpbin.org/cookies", set_cookies("MeWant" = "cookies"))
content(r)$cookies  # get response cookies
require 'httparty'

# get request:
response = HTTParty.get('http://httpbin.org/get')
puts response.body
puts response.code
puts response.message
puts response.headers.inspect

# post request
response = HTTParty.post('http://httpbin.org/post',
  :body => { :title => 'foo', :body => 'bar', :userId => 1 }.to_json,
  :headers => { 'Content-Type' => 'application/json' } )

puts response.body
