twitteR throws Forbidden error after entering twit

Question

I am trying to analyze some tweets using R and twitteR package. The handshake and registration code seems to work properly and I get the authorization link from R. However, when I enter the PIN obtained from https://api.twitter.com/oauth/authorize I get a "Forbidden Error." Any help is appreciated.

The Code:

TwitterOAuth<-function(){
  reqURL <- "https://api.twitter.com/oauth/request_token"
  accessURL <- "http://api.twitter.com/oauth/access_token"
  authURL <- "http://api.twitter.com/oauth/authorize"
  consumerKey <- "xxxxxxxxxxxxxxxx"
  consumerSecret <- "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
  twitCred <- OAuthFactory$new(consumerKey=consumerKey,
                             consumerSecret=consumerSecret,
                             requestURL=reqURL,
                             accessURL=accessURL,
                             authURL=authURL)
  options(RCurlOptions = list(cainfo = system.file("CurlSSL", "cacert.pem", package =  "RCurl")))
  twitCred$handshake()
  registerTwitterOAuth(twitCred)
}

The Response:

TwitterOAuth() To enable the connection, please direct your web browser to: http://api.twitter.com/oauth/authorize?oauth_token=X0AwET4FXBC7YRIWWN3iF61WFNE1DjxbfibqtfFjgcc
When complete, record the PIN given to you and provide it here: 1998913

Answer 1

Based on this blog: http://thinktostart.wordpress.com/2013/05/22/twitter-authentification-with-r/

library(RCurl)
# Set SSL certs globally
options(RCurlOptions = list(cainfo = system.file("CurlSSL", "cacert.pem", package = "RCurl")))

require(twitteR)
reqURL <- "https://api.twitter.com/oauth/request_token"

accessURL <- "https://api.twitter.com/oauth/access_token"

authURL <- "https://api.twitter.com/oauth/authorize"

consumerKey <- "yourconsumerkey"

consumerSecret <- "yourconsumersecret"

twitCred <- OAuthFactory$new(consumerKey=consumerKey,consumerSecret=consumerSecret,requestURL=reqURL,accessURL=accessURL,authURL=authURL)

twitCred$handshake(cainfo = system.file("CurlSSL", "cacert.pem", package = "RCurl"))

registerTwitterOAuth(twitCred)

Answer 2

Change your access URL from http to https.

Answer 3

You can follow this step (don't forget, valid URL is use https):

reqURL <- "https://api.twitter.com/oauth/request_token"
accessURL <- "https://api.twitter.com/oauth/access_token"
authURL <- "https://api.twitter.com/oauth/authorize"
consumerKey <- "Mjn6tdsadsadkasdklad2SV1l"
consumerSecret <- "58Z7Eldsdfaslkf;asldsaoeorjkfksaVCQtvri"
twitCred <- OAuthFactory$new(consumerKey=consumerKey,
                             consumerSecret=consumerSecret,
                             requestURL=reqURL,
                             accessURL=accessURL,
                             authURL=authURL)
twitCred$handshake()

After you run this code you will see in R console message like this :

To enable the connection, please direct your web browser to: 
https://api.twitter.com/oauth/authorize?oauth_token=scmVODruosvz6Tdsdadadasdsa
When complete, record the PIN given to you and provide it here:

Just paste the link to your browser then authorize app, last one you will get the PIN code, just copy and paste the PIN code to your R console.

registerTwitterOAuth(twitCred)

R console will show TRUE if you success.

user <- getUser("xxx")
userTimeline(user, n=20, maxID=NULL, sinceID=NULL, includeRts=FALSE)

Answer 4

I had the same "Error: forbidden" response and haven't resolved it today (although I did previously).

My R script for my Windows 8.1 system also includes this line:

download.file(url="http://curl.haxx.se/ca/cacert.pem", destfile="cacert.pem")

I found this line online with the comment to it, "this is a necessary step for Windows"

About three days ago I successfully reached Twitter after entering the online PIN number, but today I can't.

Answer 5

Cookies may be the problem: what appears to be the same thing happened to me, which was fixed when I followed the link given by twitcred$handshake() in a different browser; i.e., I had been trying in Safari, but then gave it a try once in Chrome and the PIN that I received in Chrome was accepted without a problem in R.
