Question

我在AWS“Ubuntu Server 12.04.2 LTS”上运行R Studio并通过我的浏览器访问R Studio。

当我尝试使用包ROAuth并使用代码

在Twitter API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)

我在registerTwitterOAuth(credential)说

后收到错误消息

  Error in registerTwitterOAuth(credential) : 
  ROAuth is no longer used in favor of httr, please see ?setup_twitter_oauth

但是我找不到任何进一步的解释..

Answer 1

显然twitteR软件包在我发布之前就已经更改了，所以验证的新方法是

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

请参阅https://github.com/geoffjentry/twitteR

Answer 2

我遇到了setup_twitter_oauth()函数的一些问题。我运行了以下代码，它对我没有任何错误。

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()

编辑：

刚刚对我的应用程序的access_token进行了排序，现在setup_twitter_oauth功能正常运行。

如果生成api_key，api_secret，acsess_token，access_token_secret且没有错误，请使用以下代码对R进行Twitter身份验证。

api_key = "XXXXXXXXX" // your api_key
api_secret = "XXXXXXXXXX" // your api_secret 
access_token = "XXXXXXXXXX" // your access_token 
access_token_secret = "XXXXXXXXXX" // your access_token_sceret 
setup_twitter_oauth(api_key,api_secret,access_token,
                     access_token_secret)

Answer 3

以下对我有用：

obj.saveValueName = "a sample name";
Console.WriteLine(obj.saveValueName); // Outputs "a sample name"

Answer 4

这是为我工作的R脚本：

 library("twitteR")
 library("ROAuth")

download.file(url= "http://curl.haxx.se/ca/cacert.pem", destfile= "cacert.pem")
credentials <- OAuthFactory$new(consumerKey='XXXXXXXXXXXXXXXXXX',
  consumerSecret='XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX',
  requestURL='https://api.twitter.com/oauth/request_token',
  accessURL='https://api.twitter.com/oauth/access_token',
  authURL='https://api.twitter.com/oauth/authorize')

credentials$handshake(cainfo="cacert.pem")

save(credentials, file="twitter authentication.Rdata")

load("twitter authentication.Rdata")

setup_twitter_oauth(credentials$consumerKey, credentials$consumerSecret, 
credentials$oauthKey, credentials$oauthSecret)

Answer 5

我在使用setup_twitter_oauth函数时遇到了一些问题。我运行以下代码，并在运行setup_twitter_oauth函数或加载凭证文件后没有得到对象。

然后我只加载cred_1.RData文件，我得到一个似乎没用的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)

 $ signature:function (method, url)

ROAuth不再用于支持httr？ [Twitter API]
