ROAuth不再用于支持httr？[推特API]

我在AWS“Ubuntu服务器12.04.2 LTS”上运行R Studio，并通过浏览器访问R Studio

当我尝试使用带有代码的包

ROAuth

在Twitter API上进行身份验证时：

credential<-OAuthFactory$new(consumerKey="xxxxx",
                             consumerSecret="xxxxx",
                             requestURL="https://api.twitter.com/oauth/request_token",
                             accessURL="https://api.twitter.com/oauth/access_token",
                             authURL="https://api.twitter.com/oauth/authorize")

credential$handshake()
registerTwitterOAuth(credential)

---

但是我找不到任何进一步的解释

显然，在我发布此消息之前，twitteR软件包已经更改，因此新的身份验证方法是

setup_twitter_oauth(CUSTOMER_KEY, CUSTOMER_SECRET, ACCESS_TOKEN, ACCESS_secret, credentials_file=NULL)

---

请参见

我在使用setup\u twitter\u oauth功能时遇到一些问题。 我运行以下代码，在运行setup_twitter_oauth函数或加载凭证文件后，没有获取对象

然后我加载cred_1.RData文件，得到一个似乎没有用的sig objetc

我在windows上安装了github版本的软件包

rm(list = ls(,all=T))


setwd("D:\\TWEETS\\cuenta_1")
library(twitteR)
library(httr)

# Credenciales

consumer_key =   "xxxxxxxxxxxxxxxx"
consumer_secret = "xxxxxxxxxxxxxxxx"
access_token = "xxxxxxxxxxxxxxxxxxx"
access_secret = "xxxxxxxxxxxxxxxx"

credentials_file = "cred_1.RData"

setup_twitter_oauth(consumer_key, consumer_secret, access_token, access_secret, credentials_file)
load_twitter_oauth("cred_1.RData")

ls()

> ls()
[1] "access_secret"    "access_token"     "consumer_key"     "consumer_secret" 
[5] "credentials_file"


> load("cred_1.RData")
> 
> ls()
[1] "access_secret"      "access_token"       "consumer_key"       "consumer_secret"    "credentials_file"   "load_twitter_oauth" "set_oauth_sig"     
[8] "sig"               
> 
> print(sig)
Config: 
List of 1
 $ signature:function (method, url)

我对

设置\u twitter\u oauth（）函数有一些问题。我运行了下面的代码，它对我来说没有任何错误

library(RCurl)
require(twitteR)
library(ROAuth)
reqURL <- "https://api.twitter.com/oauth/request_token"
accessURL <- "https://api.twitter.com/oauth/access_token"
authURL <- "https://api.twitter.com/oauth/authorize"
api_Key <-  "XXXXXXX"
api_Secret <- "XXXXXXXXXXXXXXXXX"

twitCred <- OAuthFactory$new(consumerKey=api_key,
                            consumerSecret=api_secret,
                            requestURL=reqURL,
                            accessURL=accessURL,
                            authURL=authURL
)
twitCred$handshake()

以下几点对我很有用：

packages <- c("twitteR","ROAuth")#"openssl","base64enc"
### checking if packages are already installed and installing if not
check.install.load.Package<-function(package_name){
  if(!package_name%in%installed.packages()){

}
for(package in packages){
  check.install.load.Package(package)
}
