Question

我使用RStudio并且在公司防火墙后面，并将.Renviron文件设置为：

options(internet.info = 0)

http_proxy="http://user:pw@proxy:port"
http_proxy_user="user:pw"
https_proxy="https://user:pw@proxy:port"
https_proxy_user="user:pw"

库（HTTR）

如果我这样做：

raw.result <- GET(url = "http://www.example.com/")

它有效但如果我运行

raw.result <- GET(url = "https://www.example.com/")

我一直收到这个错误：

Error in curl::curl_fetch_memory(url, handle = handle) : 
  error setting certificate verify locations:
  CAfile: /mingw64/ssl/certs/ca-bundle.crt
  CApath: none

我一直在寻找解决方案，但无法弄清楚为什么会这样。

您需要将https代理设置为系统环境变量而不是R变量。

#if you are using Windows you can use this to get the proxy server and port
companyproxy <- curl::ie_proxy_info()$Proxy

#set http proxy due to company's firewall
Sys.setenv(http_proxy=companyproxy)
Sys.setenv(https_proxy=companyproxy)

#GET a https website
raw.result <- GET(url="https://httpbin.org")
