twitteR R包OAuth问题：registerTwitterOAuth（cred）中的错误：oauth参数必须是OAuth类

Posted 2021-05-05

twitteR R Package OAuth issue: Error in registerTwitterOAuth(cred) :    
oauth argument must be of class OAuth

在我第一次进行身份验证后，这是我在R中用于加载身份验证的代码。

我一直收到错误：

Error in registerTwitterOAuth(cred) : oauth argument must be of class OAuth

来自以下代码：

download.file(url="http://curl.haxx.se/ca/cacert.pem", destfile="/xxx/xxx/xxx/cacert.pem")

# to get your consumerKey and consumerSecret see the twitteR documentation for instructions
cred <- OAuthFactory$new(consumerKey='xxxxxxxxx',
                         consumerSecret='xxxxxxxxx',
                         requestURL= NOTE UNABLE TO POST LINKS IN THE POST
                         accessURL = NOTE UNABLE TO POST LINKS IN THE POST
                         authURL= NOTE UNABLE TO POST LINKS IN THE POST)

# necessary step for Windows / Mac
cred$handshake(cainfo="/xxx/xxx/xxx/cacert.pem")

# save for later use for Windows / Mac
save(cred, file="/xxx/xxx/xxx/twitter authentication.Rdata")
cred <- load("/xxx/xxx/xx/twitter authentication.Rdata")
registerTwitterOAuth(cred)

答案

做就是了：

load("/xxx/xxx/xx/twitter authentication.Rdata")

代替：

cred <- load("/xxx/xxx/xx/twitter authentication.Rdata")
