R 中 twitteR 的 SSL 证书失败 [英] SSL certificate failed for twitteR in R

问题描述

我知道有人又问过类似的问题.但是，我已经尝试了我在此处和谷歌上找到的所有内容，但似乎没有任何效果.

I know similar questions have been asked again. However, I've tried everything I found here and on google and nothing seems to work for me.

我的代码如下:

reqURL <- "http://api.twitter.com/oauth/request_token"
accessURL <- "http://api.twitter.com/oauth/access_token"
authURL <- "http://api.twitter.com/oauth/authorize"
consumerKey <- "xxxxxxxxxxx"
consumerSecret <- "xxxxxxxxxxxxxxxxxxx"
twitCred <- OAuthFactory$new(consumerKey=consumerKey,
                         consumerSecret=consumerSecret,
                         requestURL=reqURL,
                         accessURL=accessURL,
                         authURL=authURL)
twitCred$handshake(cainfo = system.file("CurlSSL", "cacert.pem", package = "RCurl"))
registerTwitterOAuth(twitCred)

我得到:[1] 真

但是如果我尝试这个:tweets = searchTwitter('blabla', n=1500)

我收到以下错误:[1] "SSL 证书问题，验证 CA 证书是否正常.详细信息:\n错误:14090086:SSL 例程:SSL3_GET_SERVER_CERTIFICATE:证书验证失败"twInterfaceObj$doAPICall(cmd, params, "GET", ...) 中的错误:错误:SSL 证书问题，请验证 CA 证书是否正常.细节:错误:14090086:SSL 例程:SSL3_GET_SERVER_CERTIFICATE:证书验证失败

以下是我电脑上的软件包和版本:

Any help would be really useful!!

推荐答案

先执行以下操作，然后运行您的代码:

Do the following first, and then run your code:

library(RCurl) 

# Set SSL certs globally
options(RCurlOptions = list(cainfo = system.file("CurlSSL", "cacert.pem", package = "RCurl")))

这通常可以解决您遇到的问题.

This usually corrects the issue you were experiencing.

编辑(2014 年 8 月):或者更好的是，尝试改用 httr 包(它是 RCurl 的友好包装器，为您设置了有用的默认选项)
