Question

我一直在关注多个博客Twitter Authentication with R和Using the R twitteR package的脚本和说明，以访问Twitter API。

library(twitteR)
library(ROAuth)

reqURL <- "https://api.twitter.com/oauth/request_token"
accessURL <- "http://api.twitter.com/oauth/access_token"
authURL <- "http://api.twitter.com/oauth/authorize"
consumerKey <- "-----------------"
consumerSecret <- "-----------------------------"
twitCred <- OAuthFactory$new(consumerKey=consumerKey,
                             consumerSecret=consumerSecret,
                             requestURL=reqURL,
                             accessURL=accessURL,
                             authURL=authURL)
download.file(url="http://curl.haxx.se/ca/cacert.pem",
              destfile="cacert.pem")
twitCred$handshake(cainfo = system.file("CurlSSL", "cacert.pem",
                   package = "RCurl"))
registerTwitterOAuth(twitCred)
testSearch = searchTwitter("#food", n = 10, cainfo="cacert.pem")

我没有注册问题，一切顺利，直到我开始使用searchTwitter（）函数，它会抛出以下错误。

testSearch = searchTwitter("#food", n = 10, cainfo="cacert.pem")
[1] "Unauthorized"
Error in twInterfaceObj$doAPICall(cmd, params, "GET", ...) : 
  Error: Unauthorized

我试图通过查看TwitteR, ROAuth and Windows: register OK, but certificate verify failed和Twitter client for R以及twitteR help unable to authorize even with registering处的类似问题来解决问题

但是，我没有成功解决此问题。非常欢迎任何帮助。提前谢谢。

我遇到了完全相同的问题。

为我修复的是我在https://dev.twitter.com/上的应用设置，并为访问类型选择“读取，写入和访问直接消息” - 您尝试过吗？
