r - 使用 RGoogleDocs 登录谷歌电子表格

Question

根据https://github.com/hammer/google-spreadsheets-to-r-dataframe上的指示: 我尝试通过以下方式登录:

sheets.con = getGoogleDocsConnection(getGoogleAuth(, , service = "wise")) spreadsheets = getDocs(sheets.con)

在第二行之后我得到了错误:

Error in function (type, msg, asError = TRUE)  : 
  SSL certificate problem, verify that the CA cert is OK. Details:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

有什么问题，如何让它接受证书？

Answer 1

要么将 verifypeer=FALSE 传递给 RCurl::getURL:

sheets.con = getGoogleDocsConnection(getGoogleAuth(<name>,<psw>, service = "wise")) 
spreadsheets = getDocs(sheets.con, ssl.verifypeer=FALSE)

或者转而传递 cainfo=system.file("CurlSSL", "cacert.pem", package = "RCurl")。
