r - 从 R 访问 bitly OAuth2 API

Question

我希望能够访问 bitly OAuth2 api来自 R 并且想知道是否有任何示例实现，或者更好的是，R 库/包装器用于 bitly API 周围？

twitteR 库跨越 R OAuth library, ROAuth ，但这大概不支持 OAuth2？或者 OAuth2 会接受 OAuth1 的提议吗？

Answer 1

这是一种使用httr 的方法——它在packages' examples on GitHub 的脉络中:

require(jsonlite)
require(httr)

# 1. Find OAuth settings for bit.ly:
# http://dev.bitly.com/authentication.html
bitly <- oauth_endpoint(
  authorize = "https://bitly.com/oauth/authorize",
  access = "https://api-ssl.bitly.com/oauth/access_token")

# 2. Register an application at http://dev.bitly.com/my_apps.html
# Insert your values below - if secret is omitted, it will look it up in
# the BITLY_CONSUMER_SECRET environmental variable.
myapp <- oauth_app("bitly", 
                   key = ".............................", # Client ID
                   secret = "............................") # Client Secret

bitly_token <- oauth2.0_token(bitly, myapp, cache = FALSE) 

# 4. Use API
req <- GET("https://api-ssl.bit.ly/v3/user/info", query = list(access_token = bitly_token$credentials$access_token))
stop_for_status(req)
content(req)$data$profile_url
# [1] "http://bitly.com/u/lukeanker"
