我正在尝试在 R 中挖掘 twitter 数据,但开始时遇到了麻烦。我创建了一个 twitter 帐户,一个 twitter 开发人员中的应用程序,将设置更改为读取、写入和访问,创建了我的访问令牌,并按照说明注册它:

我的代码:

  > library(twitteR)
  > download.file(url="http://curl.haxx.se/ca/cacert.pem",
  +               destfile="cacert.pem")
  > requestURL <- "https://api.twitter.com/oauth/request_token"
  > accessURL <- "https://api.twitter.com/oauth/access_token"
  > authURL <- "https://api.twitter.com/oauth/authorize"
  > consumerKey <-"my key"      #took this part out for privacy's sake
  > consumerSecret <- "my secret"       #this too
  > twitCred <- OAuthFactory$new(consumerKey=consumerKey, consumerSecret = consumerSecret, requestURL = requestURL, accessURL = accessURL, authURL = authURL)
  > twitCred$handshake(cainfo="cacert.pem")

 To enable the connection, please direct your web browser to: 
 https://api.twitter.com/oauth/authorize?oauth_token=zxgHXJkYAB3wQ2IVAeyJjeyid7WK6EGPfouGmlx1c
 When complete, record the PIN given to you and provide it here: 0010819
 > registerTwitterOAuth(twitCred)
   [1] TRUE
 > save(list="twitCred", file="twitteR_credentials")

然而,这个:

 > s <- searchTwitter('#United', cainfo="cacert.pem")       
   [1] "Unauthorized"
   Error in twInterfaceObj$doAPICall(cmd, params, "GET", ...) : 
   Error: Unauthorized

我快要发脾气了。如果有人可以向我解释出了什么问题,或者更好的是如何解决它,我将非常感激。

谢谢你。
