我正在尝试使用 RStudio 的 twitteR 包。
但是我收到一个错误：

“需要代理身份验证”，有时 - “找不到主机”。

有很多线程有同样的问题。
我已经尝试了一切（--internet2,R by setting "~/Rgui.exe" http_proxy=http:/999.99.99.99:8080/ http_proxy_user=ask）。但它没有用。

在我的代码下方找到我的代码（我从我的办公室桌面 RStudio 运行），它需要身份验证：proxyuserpwd="**domain//username:pwd**".

我不确定这条线。我尝试了各种组合，但都没有奏效。

rm(list=ls())
library(twitteR)
library(ROAuth)
library(RCurl)

options(RCurlOptions = list(
  verbose = TRUE,
  proxy ="http://proxy1.domain.com:8080",
  proxyuserpwd="domain//username:pwd",
  proxyauth="ntlm"))

reqURL <- "http://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="cacert.pem")

但是，当我尝试使用以下代码时。

library("RCurl")
opts <- list(
proxy         = "proxy1.domain.com", 
proxyusername = "domain", 
proxypassword = "pwd",
proxyport     = 8080
)
getURL("http://stackoverflow.com", .opts = opts)

...我成功了。

我从这里尝试了多线程解决方案，但他们的解决方案都没有奏效。我不确定我在哪里犯了错误。（是我需要与困扰我的用户名一起放置的域）有人可以对这个问题有所了解。

更新：

当我在 RGui 中运行相同的代码时（设置“~/Rgui.exe”http_proxy=http:/999.99.99.99:8080/http_proxy_user=ask），它提示输入用户名和密码以下载 cacert.pem。
但是当我尝试握手时，它会抛出同样的错误：

错误：需要代理身份验证。

更新：

我收到以下错误：
Error in function (type, msg, asError = TRUE) : Received HTTP code 407 from proxy after CONNECT

更新 正如托马斯建议的那样 - 尝试过 

reqURL <- "https://api.twitter.com/oauth/request_token"
accessURL <- "https://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)

h <- getCurlHandle(
proxy         = "proxy1.domain.com", 
proxyusername = "username",  #but i have to always prefix my domain with username(Domain\username or domain\\username or domain//username)
proxypassword = "password",
proxyport     = 8080,
cainfo = "cacert.pem")
twitCred$handshake(curl=h)

我收到以下错误
Error in strsplit(response, "&") : non-character argument
我正在使用回溯输出更新链接
5: strsplit(response, "&")
4: lapply(X = X, FUN = FUN, ...)
3: sapply(strsplit(response, "&")[[1]], strsplit, "=")
2: parseResponse(resp)
1: twitCred$handshake(curl = h)

感谢托马斯，您的帮助 - 我解决了这个问题。 

rm(list=ls())
library(twitteR)
library(ROAuth)
library(RCurl)

reqURL <- "http://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)

h <- getCurlHandle(
proxy         = "proxy1.domain.com", 
 proxyusername = "username", 
proxypassword = "pwd",
proxyport     = 8080,     cainfo = "cacert.pem")

twitCred$handshake(curl=h)

To enable the connection, please direct your web browser to:

我真的对代理服务器一无所知，但你为什么不试试这个握手线（明确指定 curl 句柄）：

h <- getCurlHandle(
      proxy         = "proxy1.domain.com", 
      proxyusername = "domain", 
      proxypassword = "pwd",
      proxyport     = 8080,
      cainfo = "cacert.pem")
twitCred$handshake(curl=h)

我也在代理服务器后面工作，并且能够使用以下代码访问 twitter。

consumer_key <- '<put your consumer key here>'
consumer_secret <- '<put your consumer secret here>'
access_token <- "<put your access token here>"
access_secret <- "<put your access token secret here>"
set_config(use_proxy(url='proxy- address',port-number, username, password))
setup_twitter_oauth(consumer_key,consumer_secret, access_token , access_secret)

并且能够获取推文。我还写了一篇博客，逐步解决这个问题。您可以从http://analyticsinall.blogspot.in/search/label/Analytics%20for%20Business访问它
