same error i am facing…any help

Hi irin, eventually I fixed the problem . You need to re-create your application on twitter again ! How? Simply go to your application on twitter and DELETE and then make a new application that’s it and it works. Let me know if you got result.

I have same problem, I could finish authentication successfully
#----------
registerTwitterOAuth(twitCred)
[1] TRUE
#-------------
but I could not access twitter API by getURL:
#----------
getURL(“https://api.twitter.com/1.1/statuses/show.json?id=340648555121352705.JSON”,
cainfo = system.file(“CurlSSL”, “cacert.pem”, package = “RCurl”))

[1] “{"errors":[{"message":"Bad Authentication data","code":215}]}”
#---------
what am I doing wrong?
@cmq71: I made new application also, but it does not work.

Did anyone make it work??? I have already deleted the app and created a new one. I’m on Windows XP Home edition. I use R 3.0.2 and my packages are updated.

I don’t own a domain. I’m using my blog URL in the website field. Could this be the problem?

#6

has there been a solution to this??

#7

the creation of a new app, new api key and secret, worked for me

#8

Error in function (type, msg, asError = TRUE) :
SSL certificate problem, verify that the CA cert is OK. Details:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

reqURL ← “https://api.twitter.com/oauth/request_token”
accessURL ← “https://api.twitter.com/oauth/access_token”

Error: Unauthorized

I deleted and created new app, yet I am getting the error: Unauthorized message.
Please help resolve this issue.

#11

you have “mykey” both in the consumerKey and consumerSecret line, you want something like “mysecretkey” in the consumerSecret assignment.

#12

could you give your R code? thanks

#13

have tried all of these but didn’t work. any solution about this “Error: Unauthorized” ???

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

twitCred$handshake()
twitCred$handshake(cainfo=“cacert.pem”)
twitCred$handshake(cainfo=“cacert.pem” , ssl.verifypeer = FALSE )
twitCred$handshake(cainfo = system.file(“CurlSSL”, “cacert.pem”, package = “RCurl”))

#14

finally i got the solution, please try this method

library(devtools)
install_github(“twitteR”, username=“geoffjentry”)
library(twitteR)

api_key = “aaa”
api_secret = “bbb”
access_token = “ccc”
access_token_secret = “ddd”
setup_twitter_oauth(api_key,api_secret,access_token,access_token_secret)

#15

I tried the above but last line error.

Error: could not find function “setup_twitter_oauth”
