我知道类似的问题又被问到了。但是,我已经尝试了在这里和谷歌上找到的所有东西,但似乎没有什么对我有用。
我的代码如下:
reqURL <- "http://api.twitter.com/oauth/request_token"
accessURL <- "http://api.twitter.com/oauth/access_token"
authURL <- "http://api.twitter.com/oauth/authorize"
consumerKey <- "xxxxxxxxxxx"
consumerSecret <- "xxxxxxxxxxxxxxxxxxx"
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)
我在这里得到:
[1] TRUE
但如果我试试这个:
tweets = searchTwitter('blabla', n=1500)
我收到以下错误:
[1] "SSL certificate problem, verify that the CA cert is OK. Details:\nerror:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed"
Error in twInterfaceObj$doAPICall(cmd, params, "GET", ...) :
Error: SSL certificate problem, verify that the CA cert is OK. Details:

任何帮助都会非常有用!
