Windows上使用R的ROauth，授权后响应无效
我在R中使用下面的脚本，但是当我将用户重定向到oauth的浏览器时。 并输入PIN码，它会打印一个错误。 请在这种情况下帮助我。 谢谢。
cred=OAuthFactory$new(consumerKey="xxxxx",consumerSecret="xxxxx",requestURL="https://api.twitter.com/oauth/request_token",accessURL="https://api.twitter.com/oauth/authorize",authURL="https://api.twitter.com/oauth/access_token");
cred$handshake(cainfo="cacert.pem");
To enable the connection, please direct your web browser to:
https://api.twitter.com/oauth/access_token?oauth_token=xxxxxxxxxxxxxxxxxxxx
When complete, record the PIN given to you and provide it here: xxxx
Error in cred$handshake(cainfo = "cacert.pem") : Invalid response after authorization.
You likely misentered your PIN, try rerunning this handshake & browser authorization to get a new PIN.

您的代码中存在错误的网址。 用http代替https ：
requestURL <- "https://api.twitter.com/oauth/request_token"
accessURL = "http://api.twitter.com/oauth/access_token"
authURL = "http://api.twitter.com/oauth/authorize"
consumerKey = "mykey"
consumerSecret = "mysecret"
Cred <- OAuthFactory$new(consumerKey=consumerKey,
consumerSecret=consumerSecret,
requestURL=requestURL,
accessURL=accessURL,
authURL=authURL)
Cred$handshake(cainfo = system.file("CurlSSL", "cacert.pem", package = "RCurl") )
registerTwitterOAuth(Cred)
我通常会将此作为评论来写，但这似乎出现了很多。
