我一直在關注來自多個博客Twitter Authentication with R和Using the R twitteR package的腳本和指令以訪問twitter API。註冊後未經授權訪問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")
我沒有問題登記,一切正常,直到我開始使用searchTwitter()函數,它拋出我下面的錯誤。
testSearch = searchTwitter("#food", n = 10, cainfo="cacert.pem")
[1] "Unauthorized"
Error in twInterfaceObj$doAPICall(cmd, params, "GET", ...) :
Error: Unauthorized
我試圖通過看TwitteR, ROAuth and Windows: register OK, but certificate verify failed和Twitter client for R和類似的問題在twitteR help unable to authorize even with registering
然而,爲了解決這個問題,我是不成功的,以解決此問題。任何幫助是非常受歡迎的。提前致謝。

嗨@Stephen,我在Stackoverflow上看到了這個答案。事實上,當我創建一個新應用程序時,問題解決了,但設置沒有區別,訪問類型設置爲「讀取,寫入和訪問直接消息」。無論如何,謝謝你回答希望你的應用程序運行良好。 – MKao
