大家好
我開始使用TwitteR 做Text Mining,
目前就是自己註冊了Twitter 建立了一個App
然後跟著網路上的步驟連結R與自己的App
就可以用指令搜尋需要的Tweet
然而 初學者總是會遇到一些系統問題
我使用的是 Mac 10.13.6
我是在
# Saving and using certification to connect to Twitter
# Asing for access
這裡的時候 R會direct我到一個authorize的頁面
但我一按下Authorize (這是我的Twitter App的Authorize頁面）
就顯示：
127.0.0.1 refused to connect.
於是我就開始搜尋可能原因
以下先放上我的code
以及stackoverflow上面有人貼的command
我的mkdir: /private/var/log/apache2: File exists
sudo apachectl configtest
Syntax OK
並沒有出現error message
不知道有沒有也是mac使用者版友有類似經驗的
願意分享一下？
謝謝大家！
[程式範例]:
## Install packages and set up working directory
install.packages(c( "twitteR", "ROAuth", "RCurl" ))
## call the packages ##
library(twitteR)
library(ROAuth)
library(RCurl)
## Getting a curl certification
download.file(url = "http://curl.haxx.se/ca/cacert.pem", destfile =
"cacert.pem")
## Setting the certification from Twitter
# Set constant requestURL
requestURL <- "https://api.twitter.com/oauth/request_token"
# Set constant accessURL
accessURL <- "https://api.twitter.com/oauth/access_token"
# Set constant authURL
authURL <- "https://api.twitter.com/oauth/authorize"
# consumer key and consumer secret
consumerKey <- XXXXXX
consumerSecret <- OOOOOO
# Create authorization object by calling function OAuthFactory
twitCred <- OAuthFactory$new ( consumerKey = consumerKey, consumerSecret =
consumerSecret,
requestURL = requestURL,
accessURL = accessURL,
authURL = authURL)
# Saving and using certification to connect to Twitter
# Asing for access
twitCred$handshake( cainfo = "cacert.pem")
這邊跳出

我也順利進到頁面 但一點authorize就出現

127.0.0.1 refused to connect.
