How do I resolve this RCurl error: "SSL certificate problem: certificate has expired"?

Question

我只是想在下面获得一个简单的 URL 响应，但我收到以下错误。该网站是有效的，我过去已经从中提取了数千次。

jsonString <- getURL(full_url)

Error in function (type, msg, asError = TRUE)  : 
  SSL certificate problem: certificate has expired

有什么想法吗？我是运行 R 4.0.0（我升级以查看是否可以解决问题）并且拥有最新的 RCurl 包。

过去几周我一直面临同样的问题。因此，如果您使用 Rstudio 和 Rcurl 包并收到 "Error in function (type, msg, asError = TRUE) : SSL certificate problem: certificate has expired" 错误，请尝试以下代码。

RCurl_raw <- RCurl::postForm(
    uri = redcap_uri
    , token = token
    , content = 'record'
    , format = 'csv'
    , type = 'flat'
    , rawOrLabel = 'raw'
    , exportDataAccessGroups = 'true'
    , .opts = RCurl::curlOptions(ssl.verifypeer=FALSE, verbose=TRUE)
)

ssl.verifypeer 应该是假的。
