demo: oauth1-twitter.r does not work

[petermeissner]

The demo shown in oauth1-twitter.r does not work (tested on Win7 / Win8 with up to date httr from CRAN)

require(httr)

## Loading required package: httr

#1. Find OAuth settings for twitter:
#    https://dev.twitter.com/docs/auth/oauth
oauth_endpoints("twitter")

## <oauth_endpoint>
##  request:   https://api.twitter.com/oauth/request_token
##  authorize: https://api.twitter.com/oauth/authenticate
##  access:    https://api.twitter.com/oauth/access_token

#2. Register an application at https://apps.twitter.com/
#    Insert your values below - if secret is omitted, it will look it up in
#    the TWITTER_CONSUMER_SECRET environmental variable.
myapp <- oauth_app("twitter", 
                   key = "KeyForTwitterApp", 
                   secret="TheAppsTwitterSecret")

#3. Get OAuth credentials
twitter_token <- oauth1.0_token(oauth_endpoints("twitter"), myapp)

## Error in init_oauth1.0(self$endpoint, self$app, permission = self$params$permission): client error: (401) Unauthorized

#4. Use API
req <- GET("https://api.twitter.com/1.1/statuses/home_timeline.json",
  config(token = twitter_token))

## Error in config(token = twitter_token): object 'twitter_token' not found

stop_for_status(req)

## Error in status_code(x): object 'req' not found

content(req)

## Error in inherits(x, "response"): object 'req' not found

Works for me. Auth failure usually indicates you've set up your app incorrectly. Make sure you've set the callback url to "http://127.0.0.1:1410"

[petermeissner]

That was the missing part. Thanks.

[prof-joe]

If I set the callback URL to localhost:1410 twitCred$handshake(cainfo="cacert.pem") does not work, and if set this to space, the browser appears correctly. On the other hand, it seems that setup_twitter_oauth(consumerKey, consumerSecret) requires localhost:1410 but the R terminal disappears then. Can you explain why? I think many people are in trouble.

[petermeissner]

I remember reading a lot about TwitterAPI not working with localhost as callback URL. Try replacing ...

localhost:1410

... by verbose ...

http://127.0.0.1:1410

... and see if this solves the problem.

[prof-joe]

I did it. The situation remains the same.

[schnee]

the "http://127.0.0.1:1410" solution resolved the issue I was having with this.

[briholt100]

I'm having the same problem, even after making the callback = http://127.0.0.1:1410/

After executing this code: twitter_token <- oauth1.0_token(oauth_endpoints("twitter"), myapp)

Rstudio gives me this message while alerting me to a fatal error, wishing to restart a session:

Waiting for authentication in browser.... press ESC/ctrl + C to abort Error in withCallingHandlers(trycatch(evalq((function (has = TRUE, parent = parent.frame(),: object '.rcpp_warning_recorder' not found

I've been trying this on 4 different platforms: Windows 7 and 8, and a linux mint and lubuntu. I've also tried on 2 different locations, one at home (win 8 and the 2 linux machines) and one at work (the win 7).

Where should I begin to trouble shoot this?

[hadley]

@briholt100 that's a different issue, and can be solved by reinstalling Rcpp.

[briholt100]

Thank you. That worked for my Window machines. But it didn't help with the linux machines. I'll have to dig a bit more. Thanks again.

[briholt100]

my linux machines just needed RCurl reinstalled and httr is working. Still learning; thanks for your help.

[ncdingari]

@prof-joe does it finally work? I am having same issue. Handshake does not work and says "Can not connect to server 127.0.0.1"

[isomorphisms]

This helped me with the same error http://stackoverflow.com/a/29505711/563329

[mikefantast]

Thank you for this! It was driving me crazy.

Hi @geoffjentry i have tried almost everything suggested by most of the people here but still i am getting the same error. can someone please help me out with this.

setup_twitter_oauth(api_key,api_secret,access_token,access_token_secret) [1] "Using direct authentication" Error in check_twitter_oauth() : OAuth authentication error: This most likely means that you have incorrectly called setup_twitter_oauth()'

[geoffjentry]

@aishwarya91 Hi - your comment is about twitteR, not httralthough it's possible that the underlying cause leads you back here anyways as the former acts mainly as a passthrough for the latter.

Also note that twitteR is deprecated in favor of rtweet from @mkearney so you might want to look into using that instead.
